## The Extent of Relief GDA Seeks and the Reason GDA Seeks the Relief

1. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 61.113(a) Relief from Section 61.113(a), entitled Private pilot privileges and limitations: Pilot in command, is requested to the extent necessary to allow a PIC holding a private pilot certificate and an airman medical certificate, and who has completed the Trimble UX5 UAS training requirements, to conduct the proposed UAS flight operations for compensation. This relief is requested since the limitation set forth in Section 61.113(a) states thatno person who holds a private pilot certificate may act as pilot in command of an aircraft that is carrying passengers or property for compensation or hire; nor may that person, for compensation or hire, act as pilot in command of an aircraft. GDA agrees that an equivalent level of safety will be maintained because no PIC will be allowed to operate the Trimble UX5 unless that PIC has met certain flight-hour requirements. The PIC will demonstrate the ability to safely operate the Trimble UX5 UAS in a manner consistent with the operations specifications as set forth herein, including evasive and emergency maneuvers, as well as maintaining appropriate distances from people, vessels, vehicles and structures. Further, GDA proposes that the additional airmanship experience of a commercially certified pilot would be unnecessary for the GDA’s specific proposed operations.

2. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.7(a) Relief from Section 91.7(a), entitled Civil aircraft airworthiness, is requested to the extent required to allow GDA to determine thatthe Trimble UX5 UAS is in an airworthy condition prior to every flight by ensuring that the UAS is in compliance with the Trimble UX5

### Aerial Imaging Solution User Guide and Maintenance, attached as Appendix B and C, respectively. GDA seeks the requested relief because the Trimble UX5 UAS does not require an airworthiness certificatein accordance with 14 C.F.R. Part21, Subpart H. Therefore, GDA will ensure that the Trimble UX5 UAS is in an airworthy condition based upon its compliance with the operating documents prior to every flight, and as stated in the conditions and limitations (Appendix D).
3. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.119(c) Relief from Section 91.119(c), entitled Minimum safe altitudes: (c) Over other than congested areas, is required because all proposed operations of the Trimble UX5 UAS will take place at an altitude at or below 400 feet AGL. The relief is requested since the limitations set forth in Section 91.119(c) state that no person may operate an aircraft below 500 feet above the surface. As set forth more fully below, GDA submitsthat a level of safety equivalent to Section 91.119(c) will be maintained because operations will be conducted in areas with controlled access and GDA will operate the Trimble UX5 UASunder the safety provisions contained within this petition and the Trimble UX5 Aerial Imaging Solutions operating documents. Additionally, relief from Section 91.119(c) isrequested to the extent necessary to allow operations to be conducted closer than 500 feet topersons, vessels, vehicles, or structures. This relief is requested since the limitations set forth in Section 91.119(c) prohibit operating an aircraft closer than 500 feet to a person, vessel, vehicle, or structure. As set forth more fully below, GDA submits an equivalent level of safety will be maintained because operations closer than 500 feet to a person, vessel, vehicle, or st ructure will first require that the operator receive permission from any nonparticipating persons orthe person who owns/controls the property.

4. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.121 Relief from Section 91.121, entitled Altimeter settings, may be required to allow flight operations of the Trimble UX5 UAS, because the UAS’s altitude reporting equipment may be set on the ground to a pressure level of zero feet AGL, rather than localbarometric pressure or field altitude, before each flight. The Trimble UX5 UAS uses GPS equipment, and radio

### communications to transmit altitude information from the UAS to the PIC at the ground control station (GCS). Considering the limited altitude of the proposed operations, relief from 14 C.F.R. § 91.121 is sought to the extent necessary to comply with the applicable conditionsand limitations stated below. As more fully set forth herein, a level of safety equivalent to Section 91.121 will be ensured as the altitude of the Trimble UX5 UAS will be reported to air traffic control (ATC) in feet above ground level (AGL), and GDA will operate the UAS within visual line of sight, at or below 400 feet AGL.
5. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.151(a)(1) Relief from Section 91.151(a)(1) isrequested to the extent required to allow flights of the battery powered Trimble UX5 UAS during daylight hours in visual flight rules (VFR) conditions to continue for a total duration of 35 minutes, with 10 minutes of battery power remaining. GDA seeks the requested relief because without an exemption from Section 91.151(a)(1), the flight time duration of the battery powered Trimble UX5 UAS will be reduced to 20 minutes, which would eliminate the practicality of any aerial acquisition and researchoperations that GDA proposes to conduct pursuant to this Petition. The technical specifications, operating documents, and proposed operating limitations for the Trimble UX5 UAS, ensure that GDA will safely operate the battery powered UAS during daylight hours in VFR conditions for a total duration of 35 minutes, with10 minutes of battery power remaining (i.e., 20 percent remaining).
6. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) Since Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) only apply to aircraft with an airworthiness certificate, GDA requests relief from these Sections because the Trimble UX5 UAS does not require an airworthiness certificate.As set forth more fully below, the Trimble UX5 UAS meets the conditions of Section 333 for operation without an airworthiness certificate. GDA will use technicians to perform maintenance, alterations, or preventive maintenance on the unmanned aircraftsystem using the methods, techniques, and

### practices prescribed in the manufacturer’s maintenance manual. Furthermore, GDA will document and maintain all maintenance records for the Trimble UX5 UAS. 

## The Reasons Why Granting GDA’s Request Would Be in the Public Interest
Granting the present Petition will further the public interest by allowing GDA to safely, efficiently, and economically perform aerial acquisitions and research within the NAS, commercially, in support of government entities, mining and natural resources, industrial and commercial entities, the petroleum industry, and the country’s infrastructure. Additionally, use of the Trimble UX5 UAS will decrease congestion of the NAS, reduce pollution, and provide significant benefits to the economy. The benefits of the proposedoperation of the Trimble UX5 UAS will be realized without implicating any privacy issues.

1. The Public Will Benefit from the Aerial Acquisition and Research Performed GDA submits this Petition to commerciallyoperate the Trimble UX5 UAS and perform aerial acquisition and research within the NAS, in support of government entities, mining and natural resources, indust rial and commercial entities, the petroleum industry, and the country’s infrastructure. The Trimble UX5 UAS will provide safe, efficient, and economical aerial acquisition and research operations to further each of these fields, all of which are critical to the well-being of the general public. The specific operations that GDA will perf orm with the Trimble UX5 UAS demonstrate how the requested exemption will directly benefit the above-referenced industries and the public. In operations involving infrastructure, the aerial acquisition performed by the Trimble UX5 UAS will be used to preview possible sites for construction projects and provide precise topographic information about selected sites. In mining, natural resources, and the petroleum industry, the Trimble UX5 UAS will be used to surveying and planning new worksites, volumetric analysis, and performing right of way analysis. The Trim ble UX5 UAS will also further environmental management by aiding in identifying, developing, and transporting scarce water resources.

### 2. The Public Will Benefit from Decreased Congestion Of The NAS The Trimble UX5 UAS is battery powered and serves as a safe, efficient, and economical alternative to the manned aircraft traditionally utilized to obtain aerial imagery. By reducing the amount of manned aircraft neededto perform aerial acquisitions, an exemption allowing the use of a Trimble UX5 UAS would reduce the amount of manned aircraft in the NAS, reduce noise and air pollution, as well asincrease the safety of life and property in the air and on the ground. Furthermore, by reducing the number of manned aircraft operating in the NAS, congestion around airports caused by arriving and departing aircraft will be reduced. The Trimble UX5 UAS does not require an airport to takeoff or land. Likewise, a reduction of manned aircraft conducting aerial survey missions would result in fewer aircraft that must be handled by air traffic control during the ground, takeoff, departure, arrival, and landing phases of flight operations.

3. The Public Will Benefit from the Safety and Efficiency of the Trimble UX5 UAS Conducting aerial acquisitions with the Trim ble UX5 UAS, instead of manned aircraft, will greatly benefit the public by drastically reducing the levels of air and noise pollution generated during traditional aerial survey flight operations. By using battery power and electric motors, the Trimble UX5 UAS produces no air pollution, and is the most viable environmentally conscious alternative to the cabin class, six cylinder internal combustion twin engine aircraft that are typically utilized for aerial acquisitions, while burning approximately 20-30 gallons per hour of leaded aviation fuel. The Trimble UX5 UAS, while reducing the carbon footprint of aerial acquisitions, also eliminates noise pollution, as its battery powered electric motors produce lower levels of noise then a single engine aircraft. By using the Trimble UX5 UAS to perform aerial acquisitions, the substantial risk to life and property in the air and on the ground, which is usually associated with traditional manned aircraft flight operations, will be substantially reduced or completely eliminated. Aside from the lack of aircrew members located onboard the aircraft, the Trimble UX5 UAS (weighing approximately 5.5 pounds with a wingspan of 39.4 inches and no fuel on board), has less physical potential for collateral damage to lifeand property on the ground, and in the air, compared to the manned aircraft that typically conduct aerial acquisitions (weighing

### approximately 6,500 pounds with a wingspan of approximately 40 feet, a length of 34 feet, and a fuel capacity of 180 gallons).

4. Performing Aerial Acquisition Operations With the Trimble UX5 UAS Will Benefit The Economy In addition to being safe and efficient, the Trimble UX5UAS is also an economical alternative to using manned aircraft to conduct aerial acquisitions. As such, operation of the Trimble UX5 UAS will allow companies like GDA,to remain competitive and contribute to growth of the U.S. economy. Specifically, withthe rising cost of aviation fuel and the Environmental Protection Agency(“EPA”) regulatory actions phasing out leaded fuels, U.S. owned and operated companies must adopt new and alternative technology in order to remain competitive. Operating the battery powered Trimble UX5 UAS will allow companies greater operational flexibility compared to manned aircraft, but provides such flexibility without the high operational cost of a traditional manned aircraft. By operating the Trimble UX5 UAS, companies such as GDA can remain competitive and profitable, and therefore provide greater job stability to employees and contractors, which will ultimately contribute to growth of the U.S.economy. Improved financial performance of U.S. companies, through commercial use of the Trimble UX5 UAS, provides a stable workforce that increases consumer spending;improves local, state, and federal tax revenues; and allows companies to invest in research and development in order to remain competitive.
5. There Are No Privacy Issues Like the manned aerial acquisition flight operations that have been conducted for decades, the proposed operation of the Trimble UX5 UAS will not implicate any privacy issues. Specifically, the Trimble UX5 UAS will be operated in accordance with operating limitations set forth herein and the Federal Aviation Regulations, including the minimum altitude requirements of 14 C.F.R. § 91.119. Most significantly, the Trimble UX5 UAS will not be operated closer than 500 feet to any person, vessel, vehicle, or structure, which is not directly involved in the operation unless certain conditions are met. Further reinforcing the protection of privacy, the Trimble UX5 will be used to fly a preplanned route where the UAS will fly autonomously while the PIC and Observer monitor the

### airspace within the area. The Trimble UX5 will diverge from this flight path only in the event of identifying a hazard or emergency whereby the UASwill be instructed to conduct an immediate landing at a predesignated location. 

## The Reasons Why Granting The Exemption Would Not Adversely Affect Safety

1. Reasons Why the Trimble UX5 UAS Meets the Conditions of the FAA Modernization and Reform Act of 2012 (FMRA) Section 333 In consideration of the size, weight, speed, and limited operating area associated with the unmanned aircraft and its operation, GDA’s operation of the Trimble UX5 UAS meets the conditions of FMRA Section 333, and will not require an airworthiness certificate in accordance with 14 C.F.R. Part 21, Subpart H. Section 333 provides authority for UAS to operate without airworthiness certification and sets forth requirements for considering whether a UAS will create a hazard to users of the NAS or the public, or otherwise pose a threat to national security. In seeking this exemption, GDA submits that the Trimble UX5 UAS can operate safely in the NAS pursuant to FMRA Section 333, as demonstrated by: (a) the characteristics of the Trimble UX5 UAS; (b) the private pilot certification requirement; and (c) the specific operating limitations.
a. The Specifications of the Trimble UX5 UAS Demonstrate Its Safe Characteristics

The Trimble UX5 UAS does not create a hazard to users of the NAS or the public, or otherwise pose a threat to national security considering its size, weight, speed, and operational capability.

### i. Technical Specifications of the Trimble UX5 UAS PERFORMANCE SPECIFICATIONS • Maximized image footprint without compromising resolution, obtained with a custom wide-angle lens and APSC-type sensor. • Maximized coverage per flight and per hour due to large image footprint, sharp turning capability and high cruise speed. • Reversed thrust technology for a short and steep landing circuit. • Powerful propulsion system for steep climbs and high altitude flights. • High airframe service life due to wing robustness and maintainability. • Short setup time with automated procedures in Trimble Access field software. • Self-check and failsafe procedures for safe operation. • One-button export to Trimble Business Center to create deliverables. • Optimized data accuracy when processed with Trimble Business Center.

### ii. The Trimble UX5 UAS Autonomous Flight And Navigation Modes Enable the UAS to Remain within a Defined Operational Area The UX5 has a semi-autonomous navigation and control system comprised of a Ground Control Station (GCS) and auto-pilot system. All flights are pre-programmed with GPS guidance and do not require human intervention. Flight mission area and routing cannot be changed after launch. Flights are not directed by positive manualcontrol, nor are evasive maneuvers. In the case of unplanned events, the operator inputs pre-programmed evasive maneuvers from the control unit and the control unit executes that maneuver. Pre-programmed operator interventions include diversion to the right; initiation of holding at present position; suspension of mission; fly back to launch point; fly to point and hold; abort mission and land; and emergency power cut off and land (Flight Termination System). iii.

### Although a degradation or loss of the control link, and/or degradation or loss of the source of navigation, is unlikely, it is a situation that is well planned for and therefore, is a benign event. The Trimble UX5 UAS is designed for complete autonomy from launch to landing with a line of sight operator inthe loop monitoring the airframe. Automated safety functions and safety enhancing features of the UX5 include the following:

 Auto-pilot detection of lost GPS or of insufficient satellites initiates an immediate spiral landing.

 Low power on the aircraft triggers escalating alarms at GCS at 35% and 10% levels.

 If the auto-pilot detects a lost-link to the GCS for longer than 30 seconds, landing procedure begins.

 The UX5 is inherently unstable, so auto-pilot fail will result in very rapid exit from flight.

 Aircraft has an on-board failsafe that limits speed in the event of dive to approximately 14 m/s.

 The aircraft, weighing less than 6 lbs., fully loaded, is constructed of EPP foam, or similar material which is intended to absorb impact energy.

 The motor is driven by a pulse width modulated signal, not an analog signal.
iv. Mobile Operation of The Trimble UX5 UAS The Trimble UX5 UAS will not be operated in a mobile capacity. All deployments and operations of the UAS will be from a stationaryposition. The only mobility involving the use of the Trimble UX5 will be in acquisition of the UAS and relocation of the catapult launcher.
b. Flight Operations of the Trimble UX5 UAS are Limited to the Line Of Sight of A Certificated Private Pilot in Command with a Safety Observer GDA will only utilize certificated Private Pilots who possess a valid airman medical certificate to act as a pilot in command of the Trimble UX5 UAS. Additionally, a safety observer will assist all pilots during flight operations. Additionally, both the pilot in command and safety observer must complete the Trimble Operators Courseand be tested to

### ensure knowledge of the functions and operationsof the UAS. The training will be conducted at Frontier Precision, a licensed seller and certifier of the Trimble UX5 UAS, located in Denver, CO.

c. Flights will Be Conducted Pursuant toSpecific Operating Limitations. In seeking this exemption, GDA proposes tocommercially operate the Trimble UX5 UAS for the special purpose of conducting aerialacquisitions within the NAS, pursuant to the specific operating limitations set by the FAA for Trimble Navigation Limited. The limitations have been attached as Appendix D.
2. Reasons Why an Exemption from the Requirements of Section 61.113(a) Would Not Adversely Affect Safety GDA submits that an equivalent level of safety established by Section 61.113(a) will be maintained because no PIC will be allowed to operate the Trimble UX5 UAS unless that PIC has demonstrated, through the Trimble UX5 UAS training, that the PIC is able to safely operate the UAS in a manner consistent with this exemption, including evasive and emergency maneuvers and maintaining appropriate distances from people, vessels, vehicles and structures. Considering GDA’s proposed area of operations and the operating limitations (Appendix D); unlike a conventional aircraft that carries a pilot, passengers, and cargo, the Trimble UX5 UAS in this case is remotely controlled withno passengers or property of others on board. Commercial certification would be unnecessary and not improve the capabilities of the PIC for the operation of the Trimble UX5 UAS beyond the private pilot certification and Trimble UX5 UAS training. Additionally, the FAA has previously granted relief from Section 61.113(a), specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11158, 11159, 11160, 11161, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

Reasons Why An Exemption from the Requirements of Section 91.7(a) Would Not Adversely Affect Safety The level of safety established by Section 91.7(a) will be maintained because prior to every flight, GDA will ensure that the Trimble UX5UAS is in an airworthy condition and safe for flight based upon the Trimble UX5 UAS’s compliance by conducting a pre-flight check before each operation and following its operatingdocuments (i.e., the Trimble UX5 Aerial Imaging Solution User Guide, and the Trimble UX5 Aerial Imaging Solution Maintenance Guide) and as stated in the conditions and limitations. Additionally, the FAA has previously granted relief from Section 91.7(a), specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).
4. Reasons Why An Exemption From The Requirements Of Section 91.119(c) Would Not Adversely Affect Safety
Section 91.119 establishes safe altitudes for operation of civil aircraft. Specifically, 91.119(c) limits aircraft flying over areas other than congested areas to an altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet toany person, vessel, vehicle, or structure. As set forth herein, the UX5 will never operate at higher than 400 feet AGL. It will, however, be operated to avoid congested or populated areas that are depicted in yellow on VFR sectional - 5 - charts. Because aerial survey work must be accomplished at relatively low altitudes and at altitudes less than 500 feet AGL, an exemption from Section 91.119(c) is needed. The equivalent level of safety will be achieved given the size, weight, speed, and material with which the UX5 is built. Also, no flight will be taken without the permission of the land owner or those who control the land. Because of the advance notice to the landowner, all affected individuals will be aware of the survey flights. Compared to aerial survey operations

### conducted with aircraft or rotorcraft weighing far more than 5.5 lbs. and carrying flammable fuel, any risk associated with these operations will be far less than those currently allowed with conventional aircraft operating at or below 500 feetAGL. Indeed, the low-altitude operations of the UAS will maintain separation between these small-UAS operations and the operations of conventional aircraft that must comply with Section 91.119. The FAA has previously granted relief from Section 91.119(c) specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11111, 11112, 11114, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11184, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).
5. Reasons Why an Exemption from the Requirements of Section 91.121 Would Not Adversely Affect Safety The equivalent level of safety established by Section 91.121 will be maintained because the altitude of the Trimble UX5 UAS will be reported to air traffic control (ATC) in feet above ground level (AGL), and GDA will operate the UAS within visual line of sight, at or below 400 feet AGL. Furthermore, the altitude information of the Trimble UX5 UAS will be provided to the PIC via the GPS equipment, and radio communications which transmits altitude information to the control system. Prior to each flight, a zeroaltitude initiation pointis established at ground level. The FAA has previously granted relief from Section 91.121 specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 6. Reasons Why an Exemption from the Requirements of Section 91.151(a) Would Not Adversely Affect Safety This regulation prohibits an individual from beginning “a flight in an airplane under VFR conditions unless (considering wind and forecast weather conditions) there is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed – (1) During the day, to fly after that for at least 30 minutes; or (2) At night, to fly after that for at least 45 minutes.” The UX5 batteries provide approximately 50 minutes of powered flight. Without an exemption from § 14 CFR 91.151, the UAS’s flights would be limited to approximately 20 minutes in length. Given the limitations on its proposed operations and the location of those proposed operations, a longer time frame for flight in daylight VFR conditions is reasonable. GDA believes that an exemption from 14 CFR § 91.151(a) is safe and within the scope of a prior exemption. Operating the small UAS, without 30 minutes of reserve fuel does not engender the type of risks thatSection 91.151(a) was meant to prevent given the size and speed at which the UAS operates. The fact that it carries no pilot, passenger, or cargo also enhances its safety. Additionally, limiting UX5 f lights to 20 minutes would greatly reduce their utility. In the unlikely event that the UX5 should run out of fuel, it would simply land. Given its weight and construction material, the risks are less thancontemplated by the current regulation. GDA believes that an equivalent level of safety can be achieved by maintaining 10 minutes of reserve fuel (battery power), which, allowing 40 minutes of flight time, would be more than adequate to return the UAS to its planned landing zone from anywhere in its operating area. Due to the loss of utility and difficulty of maintaining line of sight of the Trimble UX5 UAS, GDA will not operate the UAS during nighttime operations. The FAA has previously granted relief from Section 91.151, specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 8811, 10808, 10673, 11042, 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 7. Reasons Why An Exemption From The Requirements Of Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), And 91.417(a) & (b) Would Not Adversely Affect Safety Section 91.405(a) requires that an aircraft operator or owner “shall have that aircraft inspected as prescribed in subpart E of this partand shall between required inspections, except as provided in paragraph (c) of this section, have discrepancies repairedas prescribed in part 43 of this chapter . . . .” Section 91.407 similarly makes reference to requirements in Part 43; Section 91.409(a)(2) requires an annual inspection for the issuance of an air worthiness certificate. Section 91.417(a) requires the owner or operator to keep records showing certain maintenance work that has been accomplished by certificated mechanics, under Part 43, or licensed pilots and records of approval of the aircraft for return to service. Maintenance of the UX5 will be accomplished by the owner/operator pursuant to the manuals, such as Exhibit 3, provided by Trimble. An equivalent level of safety will be achieved because the UAS is small in size,will carry no external payload, will operate only in restricted predetermined areas and is not a complex mechanical devise. As provided in the attached Maintenance Manual and the Safety Checklist, which were reviewed as part of Trimble’s SAC application, the operator of UX5 will ensure that the UAS is in working order prior to initiating flight, perform required maintenance, and keep a log of any maintenance that is performed. Moreover, the operator is the person most familiar withthe aircraft and is best suited to maintain the aircraft in an airworthy condition and toensure an equivalent level of safety. The UX5’s Maintenance Manual provides for replacement of the airframe every 50 hours of flight. This will ensure an equivalent level of safety to the maintenance requirements in Part 91. In addition, between such air frame replacements, should a mechanical issue arise, the aircraft will either return to its launch site or immediately land. The FAA has previously granted relief specific to UAS in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188,11189, 11191, 11192, 11193, 11194 ,11195, 11204, 11206, 11208, 11209).

## The Extent of Relief GDA Seeks and the Reason GDA Seeks the Relief

1. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 61.113(a) Relief from Section 61.113(a), entitled Private pilot privileges and limitations: Pilot in command, is requested to the extent necessary to allow a PIC holding a private pilot certificate and an airman medical certificate, and who has completed the Trimble UX5 UAS training requirements, to conduct the proposed UAS flight operations for compensation. This relief is requested since the limitation set forth in Section 61.113(a) states thatno person who holds a private pilot certificate may act as pilot in command of an aircraft that is carrying passengers or property for compensation or hire; nor may that person, for compensation or hire, act as pilot in command of an aircraft. GDA agrees that an equivalent level of safety will be maintained because no PIC will be allowed to operate the Trimble UX5 unless that PIC has met certain flight-hour requirements. The PIC will demonstrate the ability to safely operate the Trimble UX5 UAS in a manner consistent with the operations specifications as set forth herein, including evasive and emergency maneuvers, as well as maintaining appropriate distances from people, vessels, vehicles and structures. Further, GDA proposes that the additional airmanship experience of a commercially certified pilot would be unnecessary for the GDA’s specific proposed operations.

2. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.7(a) Relief from Section 91.7(a), entitled Civil aircraft airworthiness, is requested to the extent required to allow GDA to determine thatthe Trimble UX5 UAS is in an airworthy condition prior to every flight by ensuring that the UAS is in compliance with the Trimble UX5

### Aerial Imaging Solution User Guide and Maintenance, attached as Appendix B and C, respectively. GDA seeks the requested relief because the Trimble UX5 UAS does not require an airworthiness certificatein accordance with 14 C.F.R. Part21, Subpart H. Therefore, GDA will ensure that the Trimble UX5 UAS is in an airworthy condition based upon its compliance with the operating documents prior to every flight, and as stated in the conditions and limitations (Appendix D).
3. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.119(c) Relief from Section 91.119(c), entitled Minimum safe altitudes: (c) Over other than congested areas, is required because all proposed operations of the Trimble UX5 UAS will take place at an altitude at or below 400 feet AGL. The relief is requested since the limitations set forth in Section 91.119(c) state that no person may operate an aircraft below 500 feet above the surface. As set forth more fully below, GDA submitsthat a level of safety equivalent to Section 91.119(c) will be maintained because operations will be conducted in areas with controlled access and GDA will operate the Trimble UX5 UASunder the safety provisions contained within this petition and the Trimble UX5 Aerial Imaging Solutions operating documents. Additionally, relief from Section 91.119(c) isrequested to the extent necessary to allow operations to be conducted closer than 500 feet topersons, vessels, vehicles, or structures. This relief is requested since the limitations set forth in Section 91.119(c) prohibit operating an aircraft closer than 500 feet to a person, vessel, vehicle, or structure. As set forth more fully below, GDA submits an equivalent level of safety will be maintained because operations closer than 500 feet to a person, vessel, vehicle, or st ructure will first require that the operator receive permission from any nonparticipating persons orthe person who owns/controls the property.

4. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.121 Relief from Section 91.121, entitled Altimeter settings, may be required to allow flight operations of the Trimble UX5 UAS, because the UAS’s altitude reporting equipment may be set on the ground to a pressure level of zero feet AGL, rather than localbarometric pressure or field altitude, before each flight. The Trimble UX5 UAS uses GPS equipment, and radio

### communications to transmit altitude information from the UAS to the PIC at the ground control station (GCS). Considering the limited altitude of the proposed operations, relief from 14 C.F.R. § 91.121 is sought to the extent necessary to comply with the applicable conditionsand limitations stated below. As more fully set forth herein, a level of safety equivalent to Section 91.121 will be ensured as the altitude of the Trimble UX5 UAS will be reported to air traffic control (ATC) in feet above ground level (AGL), and GDA will operate the UAS within visual line of sight, at or below 400 feet AGL.
5. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.151(a)(1) Relief from Section 91.151(a)(1) isrequested to the extent required to allow flights of the battery powered Trimble UX5 UAS during daylight hours in visual flight rules (VFR) conditions to continue for a total duration of 35 minutes, with 10 minutes of battery power remaining. GDA seeks the requested relief because without an exemption from Section 91.151(a)(1), the flight time duration of the battery powered Trimble UX5 UAS will be reduced to 20 minutes, which would eliminate the practicality of any aerial acquisition and researchoperations that GDA proposes to conduct pursuant to this Petition. The technical specifications, operating documents, and proposed operating limitations for the Trimble UX5 UAS, ensure that GDA will safely operate the battery powered UAS during daylight hours in VFR conditions for a total duration of 35 minutes, with10 minutes of battery power remaining (i.e., 20 percent remaining).
6. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) Since Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) only apply to aircraft with an airworthiness certificate, GDA requests relief from these Sections because the Trimble UX5 UAS does not require an airworthiness certificate.As set forth more fully below, the Trimble UX5 UAS meets the conditions of Section 333 for operation without an airworthiness certificate. GDA will use technicians to perform maintenance, alterations, or preventive maintenance on the unmanned aircraftsystem using the methods, techniques, and

### practices prescribed in the manufacturer’s maintenance manual. Furthermore, GDA will document and maintain all maintenance records for the Trimble UX5 UAS. 

## The Reasons Why Granting GDA’s Request Would Be in the Public Interest
Granting the present Petition will further the public interest by allowing GDA to safely, efficiently, and economically perform aerial acquisitions and research within the NAS, commercially, in support of government entities, mining and natural resources, industrial and commercial entities, the petroleum industry, and the country’s infrastructure. Additionally, use of the Trimble UX5 UAS will decrease congestion of the NAS, reduce pollution, and provide significant benefits to the economy. The benefits of the proposedoperation of the Trimble UX5 UAS will be realized without implicating any privacy issues.

1. The Public Will Benefit from the Aerial Acquisition and Research Performed GDA submits this Petition to commerciallyoperate the Trimble UX5 UAS and perform aerial acquisition and research within the NAS, in support of government entities, mining and natural resources, indust rial and commercial entities, the petroleum industry, and the country’s infrastructure. The Trimble UX5 UAS will provide safe, efficient, and economical aerial acquisition and research operations to further each of these fields, all of which are critical to the well-being of the general public. The specific operations that GDA will perf orm with the Trimble UX5 UAS demonstrate how the requested exemption will directly benefit the above-referenced industries and the public. In operations involving infrastructure, the aerial acquisition performed by the Trimble UX5 UAS will be used to preview possible sites for construction projects and provide precise topographic information about selected sites. In mining, natural resources, and the petroleum industry, the Trimble UX5 UAS will be used to surveying and planning new worksites, volumetric analysis, and performing right of way analysis. The Trim ble UX5 UAS will also further environmental management by aiding in identifying, developing, and transporting scarce water resources.

### 2. The Public Will Benefit from Decreased Congestion Of The NAS The Trimble UX5 UAS is battery powered and serves as a safe, efficient, and economical alternative to the manned aircraft traditionally utilized to obtain aerial imagery. By reducing the amount of manned aircraft neededto perform aerial acquisitions, an exemption allowing the use of a Trimble UX5 UAS would reduce the amount of manned aircraft in the NAS, reduce noise and air pollution, as well asincrease the safety of life and property in the air and on the ground. Furthermore, by reducing the number of manned aircraft operating in the NAS, congestion around airports caused by arriving and departing aircraft will be reduced. The Trimble UX5 UAS does not require an airport to takeoff or land. Likewise, a reduction of manned aircraft conducting aerial survey missions would result in fewer aircraft that must be handled by air traffic control during the ground, takeoff, departure, arrival, and landing phases of flight operations.

3. The Public Will Benefit from the Safety and Efficiency of the Trimble UX5 UAS Conducting aerial acquisitions with the Trim ble UX5 UAS, instead of manned aircraft, will greatly benefit the public by drastically reducing the levels of air and noise pollution generated during traditional aerial survey flight operations. By using battery power and electric motors, the Trimble UX5 UAS produces no air pollution, and is the most viable environmentally conscious alternative to the cabin class, six cylinder internal combustion twin engine aircraft that are typically utilized for aerial acquisitions, while burning approximately 20-30 gallons per hour of leaded aviation fuel. The Trimble UX5 UAS, while reducing the carbon footprint of aerial acquisitions, also eliminates noise pollution, as its battery powered electric motors produce lower levels of noise then a single engine aircraft. By using the Trimble UX5 UAS to perform aerial acquisitions, the substantial risk to life and property in the air and on the ground, which is usually associated with traditional manned aircraft flight operations, will be substantially reduced or completely eliminated. Aside from the lack of aircrew members located onboard the aircraft, the Trimble UX5 UAS (weighing approximately 5.5 pounds with a wingspan of 39.4 inches and no fuel on board), has less physical potential for collateral damage to lifeand property on the ground, and in the air, compared to the manned aircraft that typically conduct aerial acquisitions (weighing

### approximately 6,500 pounds with a wingspan of approximately 40 feet, a length of 34 feet, and a fuel capacity of 180 gallons).

4. Performing Aerial Acquisition Operations With the Trimble UX5 UAS Will Benefit The Economy In addition to being safe and efficient, the Trimble UX5UAS is also an economical alternative to using manned aircraft to conduct aerial acquisitions. As such, operation of the Trimble UX5 UAS will allow companies like GDA,to remain competitive and contribute to growth of the U.S. economy. Specifically, withthe rising cost of aviation fuel and the Environmental Protection Agency(“EPA”) regulatory actions phasing out leaded fuels, U.S. owned and operated companies must adopt new and alternative technology in order to remain competitive. Operating the battery powered Trimble UX5 UAS will allow companies greater operational flexibility compared to manned aircraft, but provides such flexibility without the high operational cost of a traditional manned aircraft. By operating the Trimble UX5 UAS, companies such as GDA can remain competitive and profitable, and therefore provide greater job stability to employees and contractors, which will ultimately contribute to growth of the U.S.economy. Improved financial performance of U.S. companies, through commercial use of the Trimble UX5 UAS, provides a stable workforce that increases consumer spending;improves local, state, and federal tax revenues; and allows companies to invest in research and development in order to remain competitive.
5. There Are No Privacy Issues Like the manned aerial acquisition flight operations that have been conducted for decades, the proposed operation of the Trimble UX5 UAS will not implicate any privacy issues. Specifically, the Trimble UX5 UAS will be operated in accordance with operating limitations set forth herein and the Federal Aviation Regulations, including the minimum altitude requirements of 14 C.F.R. § 91.119. Most significantly, the Trimble UX5 UAS will not be operated closer than 500 feet to any person, vessel, vehicle, or structure, which is not directly involved in the operation unless certain conditions are met. Further reinforcing the protection of privacy, the Trimble UX5 will be used to fly a preplanned route where the UAS will fly autonomously while the PIC and Observer monitor the

### airspace within the area. The Trimble UX5 will diverge from this flight path only in the event of identifying a hazard or emergency whereby the UASwill be instructed to conduct an immediate landing at a predesignated location. 

## The Reasons Why Granting The Exemption Would Not Adversely Affect Safety

1. Reasons Why the Trimble UX5 UAS Meets the Conditions of the FAA Modernization and Reform Act of 2012 (FMRA) Section 333 In consideration of the size, weight, speed, and limited operating area associated with the unmanned aircraft and its operation, GDA’s operation of the Trimble UX5 UAS meets the conditions of FMRA Section 333, and will not require an airworthiness certificate in accordance with 14 C.F.R. Part 21, Subpart H. Section 333 provides authority for UAS to operate without airworthiness certification and sets forth requirements for considering whether a UAS will create a hazard to users of the NAS or the public, or otherwise pose a threat to national security. In seeking this exemption, GDA submits that the Trimble UX5 UAS can operate safely in the NAS pursuant to FMRA Section 333, as demonstrated by: (a) the characteristics of the Trimble UX5 UAS; (b) the private pilot certification requirement; and (c) the specific operating limitations.
a. The Specifications of the Trimble UX5 UAS Demonstrate Its Safe Characteristics

The Trimble UX5 UAS does not create a hazard to users of the NAS or the public, or otherwise pose a threat to national security considering its size, weight, speed, and operational capability.

### i. Technical Specifications of the Trimble UX5 UAS PERFORMANCE SPECIFICATIONS • Maximized image footprint without compromising resolution, obtained with a custom wide-angle lens and APSC-type sensor. • Maximized coverage per flight and per hour due to large image footprint, sharp turning capability and high cruise speed. • Reversed thrust technology for a short and steep landing circuit. • Powerful propulsion system for steep climbs and high altitude flights. • High airframe service life due to wing robustness and maintainability. • Short setup time with automated procedures in Trimble Access field software. • Self-check and failsafe procedures for safe operation. • One-button export to Trimble Business Center to create deliverables. • Optimized data accuracy when processed with Trimble Business Center.

### ii. The Trimble UX5 UAS Autonomous Flight And Navigation Modes Enable the UAS to Remain within a Defined Operational Area The UX5 has a semi-autonomous navigation and control system comprised of a Ground Control Station (GCS) and auto-pilot system. All flights are pre-programmed with GPS guidance and do not require human intervention. Flight mission area and routing cannot be changed after launch. Flights are not directed by positive manualcontrol, nor are evasive maneuvers. In the case of unplanned events, the operator inputs pre-programmed evasive maneuvers from the control unit and the control unit executes that maneuver. Pre-programmed operator interventions include diversion to the right; initiation of holding at present position; suspension of mission; fly back to launch point; fly to point and hold; abort mission and land; and emergency power cut off and land (Flight Termination System). iii.

### Although a degradation or loss of the control link, and/or degradation or loss of the source of navigation, is unlikely, it is a situation that is well planned for and therefore, is a benign event. The Trimble UX5 UAS is designed for complete autonomy from launch to landing with a line of sight operator inthe loop monitoring the airframe. Automated safety functions and safety enhancing features of the UX5 include the following:

 Auto-pilot detection of lost GPS or of insufficient satellites initiates an immediate spiral landing.

 Low power on the aircraft triggers escalating alarms at GCS at 35% and 10% levels.

 If the auto-pilot detects a lost-link to the GCS for longer than 30 seconds, landing procedure begins.

 The UX5 is inherently unstable, so auto-pilot fail will result in very rapid exit from flight.

 Aircraft has an on-board failsafe that limits speed in the event of dive to approximately 14 m/s.

 The aircraft, weighing less than 6 lbs., fully loaded, is constructed of EPP foam, or similar material which is intended to absorb impact energy.

 The motor is driven by a pulse width modulated signal, not an analog signal.
iv. Mobile Operation of The Trimble UX5 UAS The Trimble UX5 UAS will not be operated in a mobile capacity. All deployments and operations of the UAS will be from a stationaryposition. The only mobility involving the use of the Trimble UX5 will be in acquisition of the UAS and relocation of the catapult launcher.
b. Flight Operations of the Trimble UX5 UAS are Limited to the Line Of Sight of A Certificated Private Pilot in Command with a Safety Observer GDA will only utilize certificated Private Pilots who possess a valid airman medical certificate to act as a pilot in command of the Trimble UX5 UAS. Additionally, a safety observer will assist all pilots during flight operations. Additionally, both the pilot in command and safety observer must complete the Trimble Operators Courseand be tested to

### ensure knowledge of the functions and operationsof the UAS. The training will be conducted at Frontier Precision, a licensed seller and certifier of the Trimble UX5 UAS, located in Denver, CO.

c. Flights will Be Conducted Pursuant toSpecific Operating Limitations. In seeking this exemption, GDA proposes tocommercially operate the Trimble UX5 UAS for the special purpose of conducting aerialacquisitions within the NAS, pursuant to the specific operating limitations set by the FAA for Trimble Navigation Limited. The limitations have been attached as Appendix D.
2. Reasons Why an Exemption from the Requirements of Section 61.113(a) Would Not Adversely Affect Safety GDA submits that an equivalent level of safety established by Section 61.113(a) will be maintained because no PIC will be allowed to operate the Trimble UX5 UAS unless that PIC has demonstrated, through the Trimble UX5 UAS training, that the PIC is able to safely operate the UAS in a manner consistent with this exemption, including evasive and emergency maneuvers and maintaining appropriate distances from people, vessels, vehicles and structures. Considering GDA’s proposed area of operations and the operating limitations (Appendix D); unlike a conventional aircraft that carries a pilot, passengers, and cargo, the Trimble UX5 UAS in this case is remotely controlled withno passengers or property of others on board. Commercial certification would be unnecessary and not improve the capabilities of the PIC for the operation of the Trimble UX5 UAS beyond the private pilot certification and Trimble UX5 UAS training. Additionally, the FAA has previously granted relief from Section 61.113(a), specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11158, 11159, 11160, 11161, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 3. Reasons Why An Exemption from the Requirements of Section 91.7(a) Would Not Adversely Affect Safety The level of safety established by Section 91.7(a) will be maintained because prior to every flight, GDA will ensure that the Trimble UX5UAS is in an airworthy condition and safe for flight based upon the Trimble UX5 UAS’s compliance by conducting a pre-flight check before each operation and following its operatingdocuments (i.e., the Trimble UX5 Aerial Imaging Solution User Guide, and the Trimble UX5 Aerial Imaging Solution Maintenance Guide) and as stated in the conditions and limitations. Additionally, the FAA has previously granted relief from Section 91.7(a), specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).
4. Reasons Why An Exemption From The Requirements Of Section 91.119(c) Would Not Adversely Affect Safety
Section 91.119 establishes safe altitudes for operation of civil aircraft. Specifically, 91.119(c) limits aircraft flying over areas other than congested areas to an altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet toany person, vessel, vehicle, or structure. As set forth herein, the UX5 will never operate at higher than 400 feet AGL. It will, however, be operated to avoid congested or populated areas that are depicted in yellow on VFR sectional - 5 - charts. Because aerial survey work must be accomplished at relatively low altitudes and at altitudes less than 500 feet AGL, an exemption from Section 91.119(c) is needed. The equivalent level of safety will be achieved given the size, weight, speed, and material with which the UX5 is built. Also, no flight will be taken without the permission of the land owner or those who control the land. Because of the advance notice to the landowner, all affected individuals will be aware of the survey flights. Compared to aerial survey operations

### conducted with aircraft or rotorcraft weighing far more than 5.5 lbs. and carrying flammable fuel, any risk associated with these operations will be far less than those currently allowed with conventional aircraft operating at or below 500 feetAGL. Indeed, the low-altitude operations of the UAS will maintain separation between these small-UAS operations and the operations of conventional aircraft that must comply with Section 91.119. The FAA has previously granted relief from Section 91.119(c) specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11111, 11112, 11114, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11184, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).
5. Reasons Why an Exemption from the Requirements of Section 91.121 Would Not Adversely Affect Safety The equivalent level of safety established by Section 91.121 will be maintained because the altitude of the Trimble UX5 UAS will be reported to air traffic control (ATC) in feet above ground level (AGL), and GDA will operate the UAS within visual line of sight, at or below 400 feet AGL. Furthermore, the altitude information of the Trimble UX5 UAS will be provided to the PIC via the GPS equipment, and radio communications which transmits altitude information to the control system. Prior to each flight, a zeroaltitude initiation pointis established at ground level. The FAA has previously granted relief from Section 91.121 specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 6. Reasons Why an Exemption from the Requirements of Section 91.151(a) Would Not Adversely Affect Safety This regulation prohibits an individual from beginning “a flight in an airplane under VFR conditions unless (considering wind and forecast weather conditions) there is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed – (1) During the day, to fly after that for at least 30 minutes; or (2) At night, to fly after that for at least 45 minutes.” The UX5 batteries provide approximately 50 minutes of powered flight. Without an exemption from § 14 CFR 91.151, the UAS’s flights would be limited to approximately 20 minutes in length. Given the limitations on its proposed operations and the location of those proposed operations, a longer time frame for flight in daylight VFR conditions is reasonable. GDA believes that an exemption from 14 CFR § 91.151(a) is safe and within the scope of a prior exemption. Operating the small UAS, without 30 minutes of reserve fuel does not engender the type of risks thatSection 91.151(a) was meant to prevent given the size and speed at which the UAS operates. The fact that it carries no pilot, passenger, or cargo also enhances its safety. Additionally, limiting UX5 f lights to 20 minutes would greatly reduce their utility. In the unlikely event that the UX5 should run out of fuel, it would simply land. Given its weight and construction material, the risks are less thancontemplated by the current regulation. GDA believes that an equivalent level of safety can be achieved by maintaining 10 minutes of reserve fuel (battery power), which, allowing 40 minutes of flight time, would be more than adequate to return the UAS to its planned landing zone from anywhere in its operating area. Due to the loss of utility and difficulty of maintaining line of sight of the Trimble UX5 UAS, GDA will not operate the UAS during nighttime operations. The FAA has previously granted relief from Section 91.151, specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 8811, 10808, 10673, 11042, 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 7. Reasons Why An Exemption From The Requirements Of Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), And 91.417(a) & (b) Would Not Adversely Affect Safety Section 91.405(a) requires that an aircraft operator or owner “shall have that aircraft inspected as prescribed in subpart E of this partand shall between required inspections, except as provided in paragraph (c) of this section, have discrepancies repairedas prescribed in part 43 of this chapter . . . .” Section 91.407 similarly makes reference to requirements in Part 43; Section 91.409(a)(2) requires an annual inspection for the issuance of an air worthiness certificate. Section 91.417(a) requires the owner or operator to keep records showing certain maintenance work that has been accomplished by certificated mechanics, under Part 43, or licensed pilots and records of approval of the aircraft for return to service. Maintenance of the UX5 will be accomplished by the owner/operator pursuant to the manuals, such as Exhibit 3, provided by Trimble. An equivalent level of safety will be achieved because the UAS is small in size,will carry no external payload, will operate only in restricted predetermined areas and is not a complex mechanical devise. As provided in the attached Maintenance Manual and the Safety Checklist, which were reviewed as part of Trimble’s SAC application, the operator of UX5 will ensure that the UAS is in working order prior to initiating flight, perform required maintenance, and keep a log of any maintenance that is performed. Moreover, the operator is the person most familiar withthe aircraft and is best suited to maintain the aircraft in an airworthy condition and toensure an equivalent level of safety. The UX5’s Maintenance Manual provides for replacement of the airframe every 50 hours of flight. This will ensure an equivalent level of safety to the maintenance requirements in Part 91. In addition, between such air frame replacements, should a mechanical issue arise, the aircraft will either return to its launch site or immediately land. The FAA has previously granted relief specific to UAS in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188,11189, 11191, 11192, 11193, 11194 ,11195, 11204, 11206, 11208, 11209).

# 1 C H A P T E R1 Introduction 

# The UX5 aerial imaging rover The Trimble UX5 aerial imaging rover is an unmanned aircraft (UA). An unmanned aircraft is a generic term, and refers to an aircraft that is operated with no pilot on board. Such an aircraft is commonly also referred to as a remotely-piloted aircraft (RPA). The UX5 aerial imaging rover follows a pre-programmed path where takeoff, flight, and landing require minimal human intervention. If required, the crew operating the aircraft from the ground can intervene to change the flight path or to land. In some cases, such as communications failure or loss of GPS signal, a pre-programmed intervention is automatically activated to re-establish signal loss or to terminate the flight early and complete a safe landing. The UX5 aerial imaging rover holds a camera that takes aerial images over the defined area. During the flight, all pictures are acquired at a specified height, along parallel lines with specified overlap between the image exposures. At the same time, position information ofthe pictures is recorded for further processing in image processing software such as Trimble Business Center software. 

## Typical applications Image acquisition can be used for:

l Orthophoto creation

l Digital Elevation Model (DEM) or Digital Surface Model (DSM)

l Photogrammetry The resulting data is useful for a range of applications, including:

l Topographical surveying, particularly in remote or difficult to access areas, typical in the mining and dredging industries

l Vegetation monitoring

l Infrastructure mapping 

## ISA conditions All operating specifications provided in this guide for the UX5 aerial imaging rover are determined using International Standard Atmosphere (ISA) conditions. The ISA conditions used to determine the specifications for the UX5 aerial imaging rover are: Specification Value Humidity 0 % Air pressure 1013.25 hPa (760 mm Hg) Temperature 15 °C (59 °F) Air density 1.225 kg/m3 (0.076 lb/ft3)

## UX5 aerial imaging rover The UX5 aerial imaging rover consists ofthe wing kit (or body) and the eBox. The eBox is a removable box containing the computer that controls the UX5. The eBox is connected to a GPS antenna and a radio antenna so that the ground control station can communicate with the UX5 while it is in the air. 

## Camera The camera captures images during the flight. The camera has a large 24.3 megapixel (Sony a5100) or 16.1 megapixel (Sony NEX-5) APS-C sensor that provides sharp, detailed images. The standard RGB solution includes a UV HAZE 1 filter. The optional NIR (near infrared) solution is for use in specialized applications such as agriculture. 

## Ground control station The ground control station (GCS) is used to control the UX5 aerial imaging rover from the ground. It comprises the Trimble Tablet running the Trimble AccessTM Aerial Imaging software. The Trimble UX5 modem is connected to the Tablet to enable radio communication to the unmanned aircraft. 

## Launcher The launcher is a mechanical device that provides a safe way to launch the UX5 aerial imaging rover in the direction oftakeoff. 

## Tracker The tracker consists of a transmitter inserted in the body ofthe UX5 aerial imaging rover and a receiver. If required, the receiver is used to track the transmitter signal so the UX5 can be located once it has landed. The exact type oftracker used depends on the country where the system is being used. Check with your Trimble distributor what is available for your location.

# Projects, missions, blocks, and flights
Aproject consists of one or more missions

. Missions represent the areas to be aerially photographed. A mission area consists of one or more blocks within the mission area. By default there is one block per mission area, but if the estimated flight time for a block exceeds 50 minutes then the mission area must be divided into smaller blocks. Blocks provide flexibility so that the mission areas in a project can be covered in the smallest number of flights, because a flight can cover one or more blocks, as long as the total flight time for the blocks is less than 50 minutes. For example, a farmer wants to aerially photograph his potato fields. The farmer has two potato fields, located 500 m apart from each other. In his project, he creates a mission area for each field.

Trimble UX5 Aerial Imaging Solution User Guide 161 Introduction

By default, each mission area consists of one block. One field can be mapped in an estimated flight time of 20 minutes. But one field is so large the estimated flight time is 70 minutes. It cannot be mapped in one flight. Therefore, the farmer splits the mission area into two blocks. He could split the mission area into two equal blocks of 35 minutes, but then that would result in three separate blocks that have to be flown as three separate flights. Instead, the farmer splits the large mission area into one 45 minute block and one 25 minute block. Then the farmer adds the new 25 minute block to the flight for the existing 20 minute block. The farmer can now map both mission areas in two flights, each of 45 minutes duration. Projects, blocks, and flights can be copied so it is easy to set up similar projects or flights. Copy blocks to easily repeat flights at different heights. Or copy flights to redo a flight regularly, for example to track changes or progress over the mission area. Note – Project planning is usually done in the office. Block andflight planning can be prepared in the office but must be validated in thefield after checking actual conditions. 

# Project phases The typical phases of a project are:

l Project definition: In the office you can define one or more missions, adding details such as background maps, avoidance zones, and text fields if required. The area, ground sample distance (GSD), and the amount of image overlap are defined for each mission.

l Block definition: Depending on the size and nature of a mission area, you can split a mission area into one or more blocks. In the office you can specify the wind and flight line direction. For each block you can customize the GSD, height, and image overlap. In the field, you must validate the block properties to take into account the actual wind direction and environment.

l Flight definition: In the office you can prepare one or more flights to cover the block(s) and suggest the takeoff and landing locations. In the field you must validate the flight properties, including the selected takeoff and landing locations. The flight checklist is completed to ensure that the system is ready for the flight.

l Flight scheduling: Flight scheduling is completed outside ofthe Aerial Imaging software. Checks for flight permissions, weather, and site suitability are completed and the flight is scheduled. Before heading to the site, all equipment is checked for any damage from previous flights and all batteries are fully charged.

l Flight operation: After launching the UX5 aerial imaging rover, the flight is monitored using the ground control station. After the UX5 lands, the post-flight checklist is completed to transfer the flight data to the Tablet.

l Analysis and export: The flight and captured images are analyzed to make sure they are synchronized and the data is exported in the appropriate file format for image processing.

l Image processing: The data collected during the flight is processed using image processing software such as Trimble Business Center software.

# Creating a project
To create a new project, do one ofthe following:

l in the Home screen, click and enter the name ofthe new project in the pop-up field. The Map layers screen for the new project appears.

l In the Projects screen, click and enter the name ofthe new project in the pop-up field. The new project appears in the Projects list. Click to open the project. The Map layers screen appears. Note – Names ofprojects, mission areas, blocks, andflights can contain thefollowing characters: A- Z, a-z, 0-9, dash (-), space ( ), and underscore (_). 

# Preparing the project map A project must have at least one geo-referenced background map and one mission. Objects within a geo-referenced map are associated with a unique geographical location. To prepare the project map, select the Map layers tab. See:

l Adding a background map, page 25

l Creating the mission, page 27

l Adding information to the map, page 29 

## Adding a background map You can use an online map, an offline map, or you can add your own geo-referenced map.

l To use an online map: a. Make sure you have Internet access. b. Click on the map and then enter the location of interest. The map shows the area around the location using your preferred online map provider (see Changing the system settings, page 21). c. Zoom in or out, or pan until you view the preferred map area. Note – The online map is always available as a layer and cannot be deleted. You can have only one online map layer per project.

l To use an offline map, click and then click

. Use the toolbar that appears on top ofthe map to select the satellite map or road map for download. The current view ofthe online map, including two extra zoom levels, is downloaded as an offline map. The largest area you can download has zoom level 10, which corresponds to approximately 95 m per pixel (0.06 miles per pixel)

.

Trimble UX5 Aerial Imaging Solution User Guide 252 Planning a Project

The offline map layer ensures you will be able to view the map background during the flight, if you do not have an Internet connection in the field. You can have multiple offline map layers in a project.

l To use your own map, add a GeoTiff file that you have prepared earlier using software such as Trimble Business Center software. The GeoTiff file must be georeferenced in the WGS84 UTM datum and be less than 120 MB in size. It must use no compression or LWZ file compression only. To generate a background map using the Trimble Business Center AP module, create an orthomosaic selecting "Low" resolution and "TIFF" for the file format. To add the GeoTiff file in Aerial Imaging, click

. Navigate to the location ofthe file, select it, and then click Open
. The map shows the contents ofthe file you selected. You can have multiple GeoTiff map layers in a project. For more information on map layers, see Managing map layers, page 26
. 

### Managing map layers Click to toggle between the map view and the satellite view ofthe online map. The "Online map" is the map's default layer. The online map is always the bottom layer and cannot be moved up. An offline or GeoTiff layer sits above the online map and below any other layer, such as mission, avoidance zone, and KML file. New layers appear above a selected layer. If nothing is selected, it becomes the top layer. Layers at the top ofthe list appear as the top-most layers on the map. To hide a layer, click next to the layer name. To show a hidden layer, click next to the layer name. To disable any manipulation of a layer, click next to the layer name. To remove a layer that is no longer required, select the layer in the list and then click below the list. You cannot delete the online map layer. To rename a layer, select the layer in the list and then click the layer's name. You can now edit the name. The online map cannot be renamed. Use the and buttons to zoom in and zoom out ofthe map. Click to display the map grid lines. Use the button, to zoom the map and all of its layers to the best view. If you are viewing the map on the Tablet and it has a GPS connection, the button is available. If you pan around the map, click to center the map on the current GPS location.

During flight, the button is available. Click to center the map on the current UX5 location. 

## Creating the mission A mission is the area to be flown over at a specified ground sample distance (GSD) and image overlap. 1. To create the mission area:
a. Click and then click

. A toolbar appears on top ofthe map, allowing you to add a polygonal or rectangular area. b. Click the appropriate shape on the toolbar and then draw the shape ofthe mission area on the map:

l For a polygon, click the mouse at each boundary point.

l For a rectangle, click the mouse on the map. A standard-sized shape appears. The location ofthe mouse click is the center ofthe shape. To stop drawing and confirm the shape, click

. The mission layer appears in the map layers list to the right. To clear the shape, click

. c. To edit the mission area, select the area on the map or in the map layers list and then click

.
l To resize or reshape the area, click and move the boundary points on the map.

l To reposition the area, click and move it on the map .
l To add or delete boundary points or to rotate the shape, use the toolbar that appears on the map. To confirm your changes, click , or click to undo your changes. Note – It is not possible to add or remove boundary pointsfor a rectangular area. d. Repeat the steps above to add as many mission areas as required. 2. To edit the mission properties, click next to the mission name in the map layers list and then do the following: a. Select the type of sensor that you will use to map the mission: Sony a5100 or Sony NEX-5 b. Set the ground sample distance (GSD). The default value is the GSD value obtained by flying at a height of 100 m (328 ft)

. For more information, see GSD and height, page 28
. c. Enter the image forward ( ) and side overlap ( ). The default value is 80%. For more information, see Image forward and side overlap, page 28
. The mission properties also show the size ofthe mission area. Note – It is not possible to change the mission properties when a mission is locked.

Trimble UX5 Aerial Imaging Solution User Guide 272 Planning a Project

Tip – To disable editing of the mission area or mission properties, click next to the mission name. 

### GSD and height The GSD (ground sample distance) field specifies the distance on the ground represented by each pixel. The default resolution is 2.6 cm (1.0 ") when using the Sony a5100 sensor and 3.2 cm (1.3 ") when using the Sony NEX-5 sensor. The smaller the value in the GSD field, the more detailed the images. You should always specify a value equal to or smaller than the resolution required in the final orthophotos, after the images are processed. If the value in the GSD field is larger than the final resolution required, then the images acquired during the flight will not be detailed enough and the image processing software will need to interpolate additional pixels. This will result in images that do not have the expected resolution. The GSD field and the height at which the UX5 aerial imaging rover flies are linked. The higher the unmanned aircraft flies, the larger the distance on the ground represented by each pixel in the images acquired during the flight: Height GSD (Sony a5100) GSD (Sony NEX-5) Minimum: 75 m (246 ft) 2.0 cm (0.8 ") 2.4 cm (0.9 ") 100 m (328 ft) 2.6 cm (1.0 ") 3.2 cm (1.3 ") 150 m (492 ft) 3.9 cm (1.5 ") 4.8 cm (1.9 ") Maximum: 750 m (2460 ft) 19.6 cm (7.7 ") 23.9 cm (9.4 ")
You will first specify the GSD value for the mission when you create the mission area. This determines the default height used for all blocks in that mission. For example, if you enter 4.8 cm in the GSD field when using the Sony NEX-5 sensor, the unmanned aircraft will fly at 150 m (492 ft)

. During block definition you can adjust the height for each block, taking into account the specific obstacles in the block. 

### Image forward and side overlap The default value ofthe overlap between images is 80%. Image overlap can range from 60% to 90%. Note – Trimble does not recommend using an overlap ofless than 80%, as it may prevent (large) parts of the dataset being adjustable in the Trimble Business Center software due to the lack oftie points, especially where theflight height was low or where the area contains trees or other tall objects, or areas that lack texture. By default the forward ( ) and side overlap ( ) values are linked, so that when one value changes, the other value changes accordingly. To "break" the link so that the overlap values can be set independently, click

. To re-establish the link, click

.

Trimble UX5 Aerial Imaging Solution User Guide 282 Planning a Project

A higher overlap results in:

l better accuracy

l a higher density of flight lines on the area

l a higher number of images to process

l longer processing times for images

l longer flight duration for the same area Select the overlap value for your mission based on the accuracy, flight duration, and the number of images you require. 

## Adding information to the map You can add the following types of information to the map:

l avoidance zones

l KML files containing lines, points, images, and polygons

l .csv files containing ground control points (GCPs) 1. To create an avoidance zone:
a. Click and then

. A toolbar appears on top ofthe map, allowing you to add a polygonal, rectangular, or ellipsoidal area. b. Click the appropriate shape on the toolbar and then draw the shape ofthe avoidance zone on the map:

l For a polygon, click the mouse at each boundary point.

l For a rectangle or ellipse, click the mouse on the map. A standard-sized shape appears. The location ofthe mouse click is the center ofthe shape. To stop drawing and confirm the shape, click

. The avoidance zone appears in the list to the right. To clear the shape, click

. c. To edit the avoidance zone, select the zone on the map or in the map layers list and then click

.
l To resize or reshape the avoidance zone, click and move the boundary points on the map.

l To reposition the avoidance zone, click and move it on the map.

l To add or delete the boundary points or to rotate the shape, use the toolbar that appears on the map. To confirm your changes, click

. To undo your changes, click

.

Trimble UX5 Aerial Imaging Solution User Guide 292 Planning a Project

Note – It is not possible to add or remove boundary pointsfor a rectangular or ellipsoidal zone. Tip – To disable editing of the avoidance zone, click next to the avoidance zone name. d. Repeat the steps above to add as many avoidance zones as required. Note – The mission area and the +/- 200 m (+/- 656ft) requiredfor turns should not overlap any avoidance zone on the map. Ifthe mission area is orange, you must move the area out ofthe avoidance zone. 2. Click to add the following types of files as layers:

l A KML file that you have previously downloaded from Google Maps.

l Ground control points (GCPs) contained in a .csv file. The format for the .csv file is: Identifier, Latitude, Longitude, Altitude. The coordinates must be in the WGS84 coordinate system and the altitude in meters. There should be no header. 

# Defining the blocks
To define blocks, select the Blocks tab. Note – You must validate in thefield any blocks you have defined in the office. Each mission area defined for a project is automatically covered by one block. The block appears in the list to the right and as a yellow shape on the map. The map does not contain any blocks if you have not yet defined a mission area in the Map layers tab. When you select the block, the blue flight lines that appear over the block indicate the direction the UX5 will fly across the block. The unmanned aircraft should always fly perpendicular to the prevailing wind direction and all turns should be made into the wind. By default, the prevailing wind direction is a northerly wind. North is located at the top ofthe map. Define more blocks as required to:

l Cover the entire mission area. You will need to add more blocks if the estimated time for a block exceeds 50 minutes. The flight time can be viewed in the block properties.

l Cover different parts ofthe mission at different heights to deal with differences in terrain.

l Easily repeat flights at different heights to obtain different results. You can combine and split blocks as required to fly the mission area in the most efficient number of flights.

Trimble UX5 Aerial Imaging Solution User Guide 302 Planning a Project

The Blocks tab, for an example mission and block, is shown below:

To edit blocks: Note – Blocks with the status icon or have beenflown and cannot be edited. 1. To update the prevailing wind direction to match the expected conditions in the field: a. Tap the wind direction arrow in the top right corner ofthe map and drag it so that it indicates the direction ofthe wind at the site. The flight lines rotate accordingly. Note – To ensure smooth turns and limited headwind and tailwind duringflight, it is important to correctly indicate the prevailing wind direction. However, to disable the control oftheflight lines by wind direction, click next to the block name in the list. To manually adjust the direction oftheflight lines, tap theflight lines in the map and rotate as required. Alternatively, enter the rotation angle oftheflight lines in the field. This is useful when the mission/block area is a narrow rectangle, in which case you should always put theflight lines along the longest side ofthe rectangle, independentfrom the wind direction. b. If the flight lines change to red, this indicates that one or more flight lines (including the additional +/- 200 m (+/- 656 ft) required for turns) overlaps an avoidance zone. For more information, see Creating the mission, page 27
. Once you have edited the mission area, the block and flight lines update automatically. 2. To view the properties of a block, click next to the block name. By default the block inherits the properties ofthe mission. If required, edit the height (or GSD) and image overlap values for the block, taking into account specific obstacles in the block. Images are not acquired until the

Trimble UX5 Aerial Imaging Solution User Guide 312 Planning a Project

unmanned aircraft climbs to the specified height. The software estimates the total flight time needed to cover the block. The estimated flight time does not include the time to get to and from the takeoff and landing locations. The block properties also show the size ofthe block area and the mission to which the block belongs. 3. If the estimated flight duration exceeds 50 minutes, a warning indication appears next to the block name in the list. If the warning appears then you must split the block:
a. Select the block and then click

. A toolbar appears on top ofthe map that allows you to split the block. b. Click

. By default the block is divided through the center ofthe rectangular boundary box surrounding the block area, perpendicular to the wind direction.
c. To change the cut, manipulate the boundary points ofthe dividing line. d. Click to confirm splitting the block. The original block is divided in two and both blocks appear in the list. Note – Splitting blocks can cause existing blocks to be renumbered. e. Repeat the steps above until the flight duration of all blocks is less than 50 minutes, because you need to also consider the takeoff and landing time. f. To undo a split, select one ofthe blocks that you want to combine and click

. From the toolbar that appears on the map, click and then select the other block to merge. You can only merge adjacent blocks. Click to confirm the merge. The properties ofthe first selected block are used for the merged block. 4. To use a left turn or a right turn to enter the block during flight, click or . This setting also defines the first waypoint that the UX5 will fly to. 

## Managing blocks
To hide a block, click next to the block name. To show a hidden block, click next to the block name. To copy the default block of a mission, select the block in the list or on the map and then click below the list. The new block has the size ofthe original mission area and the properties ofthe selected block. Copying a block is useful if you need to scan the same mission area using different GSD and overlap values. To remove a block that is no longer required, select the block and then click

. If the block was created by splitting a block, all other blocks that were part ofthe splitting action are also removed. If those blocks were the only blocks that covered the mission area, the software automatically creates a new block, which has the size and properties ofthe mission.

Trimble UX5 Aerial Imaging Solution User Guide 322 Planning a Project

To rename a block, select the block in the list and then click on the block's name. You can now edit the name. Note – Blocks with the status icon or have been and cannot be renamed, changed, or removed. However, you can copy the block and then edit the copy. 

# Obstacle clearances When defining a flight, you must ensure that the selected takeoff and landing locations are clear of obstacles. Obstacle clearances for each stage ofthe flight are shown below. When you arrive at the site, visually check the takeoff and landing locations to ensure that the selected locations are free of obstacles. 

## Obstacle clearances for takeoff From 0 m (takeoff location) to 50 m: Within the first 50 m (164 ft), there must be a clear area free of obstacles within 30° to the left and right ofthe launch direction. From 50 m to 280 m: From the first 50 m (164 ft) and within 280 m (919 ft), obstacles must not appear above the safety line determined by a 15° safety angle and within 25 m (82 ft) to the left and right ofthe launch direction.

Trimble UX5 Aerial Imaging Solution User Guide 332 Planning a Project 

## Obstacle clearances for cruise flight During cruise flight, no obstacles must appear between the cruise flight height and 25 m (82 ft) below it:



## Obstacle clearances for descent When entering the landing orbit, no obstacles must appear with a 300 m (984 ft) radius ofthe center ofthe orbit. Once the UX5 has descended 25 m from the cruise flight height, the required obstaclefree area has a radius of 150 m (462 ft)

.

Trimble UX5 Aerial Imaging Solution User Guide 342 Planning a Project 

## Obstacle clearances for landing Once you confirm the landing, the UX5 starts the final leg ofthe landing. Along the final leg ofthe landing, there must be a clear area free of obstacles within 15 m to the left and right ofthe landing direction.

In the final leg ofthe landing, no obstacles must appear in the yellow zone shown in the vertical cross section ofthe landing. In addition, the landing location must be free of obstacles and meet the minimum size indicated:

l Linear landing

l Curved landing

Trimble UX5 Aerial Imaging Solution User Guide 352 Planning a Project

During the final leg ofthe landing it is possible to click the Abort button (see Handling emergencies during flight, page 82). To successfully abort the flight, extra clearances should be taken into account:

l Adding blocks to the flight, page 41

l Managing the routes between blocks, page 41

l Simulating the flight, page 42
Note – Flights with the status icon or have beenflown and cannot be renamed, changed, or removed. However, you can copy theflight and then edit the copy. 

## Setting the takeoff parameters 1. To set the takeoff parameters, in the Flight tab click beside the flight and then click beside Takeoff

. A toolbar appears on top ofthe map. 2. To set the takeoff location, do one ofthe following:

l To add a new location without GPS: In the Aerial Imaging Desktop or Tablet software, click and then click on the map to set the location. The takeoff pin appears on the map with an arrow indicating the takeoff heading and shows the "Planned and not active" status icon

. You can add as many takeoff locations as you want. Click to confirm the added locations.

l To add a new location using GPS: In the Aerial Imaging Tablet software, physically go to the takeoff location and then click

. If the location you want to fix lies within 10 m of a planned pin, the planned pin is fixed. Otherwise, a new pin with the fixed status is added to the map. The takeoff pin appears on the map with an arrow indicating the takeoff heading and shows the "Fixed and not active" status icon

. You can fix as many takeoff locations as you want.

l Click the takeoff pin on the map or use the drop-down menu in the Takeoffproperties to select any defined location. The takeoff pin status changes to "Active" or . Note – Each takeofflocation comes with default parameters (for example, the heading is set into the wind direction). Ifyou change the heading, the takeofflocation is updated accordingly. Ifyou use this location in anotherflight, the heading is set to the value ofthe latest change in all flights where the location is used. 3. To set the takeoff heading, click the arrow next to the takeoff pin and rotate to change the takeoff direction and avoid any obstacles. For more information, see Obstacle clearances for

takeoff, page 33
. By default, the takeoff heading is set into the wind direction set in the Blocks tab. Alternatively, enter the heading for the selected pin in the field. Note – Always try to takeoffinto the wind. This prevents a higher launch speed and a higher risk of launchfailures. 4. When the flight has a block linked to it or when the landing has been defined, the takeoff route is displayed. To edit the takeoff route, click and drag the waypoints on the map. Tip – To use a left turn or a right turn to enter the block, click or in the block properties in the Blocks tab. This setting also defines the first waypoint that the UX5 will fly to. The takeoff route is updated to match the type of turn selected. 5. To delete a takeoff location, click in the toolbar on top ofthe map and then from the map select the takeoff pin that you want to remove. You can delete as many takeoff locations as you want. Click to confirm the deleted locations. 

## Setting the landing properties For additional safety, the Aerial Imaging software enables you to set alternative landing parameters
. These alternative landing locations are useful if:

l The preferred landing location is suddenly unavailable due to a sudden obstacle in the landing clearance zone.

l The wind direction changes during the flight and the alternative landing location is better suited to the new conditions. To set landing properties: 1. In the Flight tab click beside the flight and then click beside Landing

. A toolbar appears on top ofthe map. 2. To set the landing location, do one ofthe following:

l To add a new location without GPS: In the Aerial Imaging Desktop or Tablet software, click and then click on the map to set the location. The landing pin appears on the map with an arrow indicating the landing heading and shows the "Planned and not active" status icon

. You can add as many landing locations as you want. Click to confirm the added locations.

l To add a new location using GPS: In the Aerial Imaging Tablet software, physically go to the landing location and then click

. If the location you want to fix lies within 10 m of a planned pin, the planned pin is fixed. Otherwise, a new pin with the fixed status is added to the map. A landing pin with fixed status has an arrow indicating the landing heading and shows the "Fixed and not active" status icon

.

Trimble UX5 Aerial Imaging Solution User Guide 392 Planning a Project

You can fix as many landing locations as you want.

l Click the landing pin on the map or use the drop-down menu in the Landing properties to select any defined location. The landing pin status changes to "Active" or . Note – Each landing location comes with default parameters (for example, the heading is set into the wind direction). Ifyou change the heading, the landing location is updated accordingly. Ifyou use this location in anotherflight, the heading is set to the value ofthe latest change in all flights where the location is used. 3. To set the landing heading, tap the arrow next to the landing pin and rotate to change the landing direction and avoid any obstacles. For more information, see Obstacle clearances for landing, page 35
. Alternatively, enter the heading for the selected pin in the field. By default, the landing heading is set into the wind direction set in the Blocks tab. To help you define the landing heading in the field, zoom in on the map to the most detailed zoom level and then walk into the heading with the GCS for about 20 to 30 meters. You will see the GCS location move on the screen. Now rotate the arrow and position the final leg ofthe landing circuit over the center ofthe GCS icon on the map. Note – Always try to land into the wind. This prevents a higher landing speed and a higher risk of damage to the UX5. 4. Set the landing zone offset. Valid values are from

-25 m to +25 m (-82 ft to +82ft)

. A negative value means that the landing location is lower than the takeoff location. The default value is 0 m, which means that the takeoff and landing locations are at the same height. 5. Set the landing type to use a linear or curved landing, depending on the landing surface and available clearances.

l The linear landing type requires less clearance and lands the UX5 on the ground more quickly, but has a larger impact on the aircraft.

l The curved landing type requires larger clearances but reduces the impact on the aircraft when it lands, and is especially suited for hard landing surfaces. For more information, see Obstacle clearances for landing, page 35
. 6. When the flight has a block linked to it, the landing route is displayed:
a. Set the landing entry to use a left or right turn, depending on which turning direction provides better visibility and is furthest away from any obstacles (see Obstacle clearances for landing, page 35). b. To edit the landing route, click and drag the waypoints on the map.

Trimble UX5 Aerial Imaging Solution User Guide 402 Planning a Project

7. To delete a landing location, click in the toolbar on top ofthe map and then from the map select the landing pin that you want to remove. You can delete as many landing locations as you want.

Note – To use a specific landingfor theflight, make sure that the landing is selected in the dropdown menu. 

## Adding blocks to the flight
1. To add blocks, in the Flight tab click beside the flight and then click beside Select blocks

. All blocks defined in the project appear on the map and in the list to the right. Only the blocks that if added will keep the flight time less than 50 minutes can be selected. For each block the status is indicated on the map:

l No icon: Not scheduled

l Scheduled

l Flown

l Flown and log files downloaded 2. From the map or the list, select one or more blocks to link to the flight. Note – The order that you select the blocksfrom the list defines the sequence that the blocks are flown, I.e. thefirst block selected isflownfirst, and so on. The selected blocks are highlighted, and the flight lines and connection routes appear on the map. Tip – To remove blocks from a flight, unselect the block in the list or the map. 3. Click to confirm the selection. The selected blocks appear in the list to the right between Takeoffand Landing, together with the default connection types. Note – A block can be linked to more than oneflight. 

## Managing the routes between blocks If a flight will cover more than one block, the software automatically connects the last waypoint of one block with the first waypoint ofthe next block. By default the connection is a straight line and is displayed between the blocks in the flight properties in the Flights tab.

Trimble UX5 Aerial Imaging Solution User Guide 412 Planning a Project

To change the connection type between blocks, click to the right ofthe connection type list entry and then:
Click... For the UX5 to... Fly straight to the first waypoint ofthe following block. If it did not yet reach the height ofthis waypoint, it orbits up in 200 m diameter circles until it reaches the height. Orbit up in 200 m diameter circles until it reaches the height ofthe following block and then fly straight to the first waypoint ofthe following block. This works if the height of the next block is higher than the previous block. Fly to the following block keeping the same height ofthe last waypoint ofthe previous block and then orbit up in 200 m diameter circles until it reaches the first waypoint of the block. This works if the height ofthe next block is higher than the previous block. Fly straight to the first waypoint ofthe following block. If it did not yet reach the height ofthis waypoint, it orbits down in 200 m diameter circles until it reaches the height. Fly to the following block keeping the same height ofthe last waypoint ofthe previous block and then orbit down in 200 m diameter circles until it reaches the first waypoint ofthat block. This works if the height ofthe next block is lower than the previous block. Orbit down in 200 m diameter circles until it reaches the height ofthe next block and then fly straight to the first waypoint ofthat block. This works if the height ofthe next block is lower than the previous block.
To edit the straight line between blocks, click and drag the waypoints on the map. Note – The connection type cannot be changed ifsequential blocks have the same height. 

## Simulating the flight After creating a flight, click to simulate the flight to check the following items:

l The UX5 uses the correct takeoff direction.

l The flight height, route, and turns used are all correct.

l The UX5 does not enter any avoidance zones.

l The UX5 uses the correct landing circuit. Note – Be aware that the simulation is an estimate oftheflight path. This is because the simulation cannot take into account the environmentalfactors, such as wind, during the actualflight.

l The eBox is not in the correct state.

l GPS signal is not OK.

l Takeoff sensor is not OK (this means that the yaw, pitch, and roll values are not yet stabilized).

l Datalogging has not started.

l The GCS has no GPS connection.

Trimble UX5 Aerial Imaging Solution User Guide 774 Completing a Flight 

## Launching the UX5 Once you have armed the system, the software prompts you to launch the aircraft. 1. Just before launch, perform the following safety checks:
a. Make sure there are no aerial objects inside the zone of operation. b. Make sure you have a clear line of sight to the UX5. c. Make sure there are no obstacles or people near the front ofthe launcher.

WARNING – Make sure you complete each of the safety checks listed at this step. Failure to do so could result in serious personal injury and damage to the UX5 or launcher.
2. When you have made sure that everything is clear in front of, above, and behind the launcher, stand behind the launcher and press the launch handle to launch the UX5.

CAUTION – Never launch without the UX5 sitting on the dock as it will damage the launch dock. The design of the launcher takes into account the weight of the UX5 sitting on the launch dock.
3. If an obstacle such as a person or animal suddenly appears in the obstacle clearance zone during takeoff

, tap in the Aerial Imaging software. The UX5 immediately powers down and returns to the ground. For more information, see Emergency software commands, page 84
. After launch, the UX5 flies to the first waypoint, which is highlighted on the map in the Dashboard tab. If the UX5 is not yet at the flight height when it reaches this point, it climbs in circles of 100 m radius until it reaches the desired height. 4. After launch, release the tension on the launcher cord elastics. Leaving tension on the launcher cord elastics for extended periods can damage the elastics.

Trimble UX5 Aerial Imaging Solution User Guide 784 Completing a Flight

To release the tension, release the force with the crank very gently while pulling the release handles in the front ofthe launcher upward. This is safest done with two people, with one person carefully winding the crank counter-clockwise to counteract the force on the elastics.



# Monitoring the flight

CAUTION – It is your responsibility to take action during flight when the safety of the UX5 aerial imaging rover or its surroundings is compromised. To do this you must:

– Have visual contact with the unmanned aircraft at all times.

– Observe the zone of operation for the unmanned aircraft and look out for other aerial objects.

– Ensure obstacle clearance.

– Keep an eye on changing weather conditions.

– Locate the unmanned aircraft on the Tablet screen.

– Monitor the flight telemetry on the Tablet screen. For information on the appropriate action to take if you see an oncoming aerial object at any point during the flight, see Handling emergencies during flight, page 82
. After takeoff, the UX5 aerial imaging rover climbs to the specified cruise height. Once the unmanned aircraft has passed its first waypoint, the second waypoint is initiated. From this point, the unmanned aircraft follows the preprogrammed flight path.

Trimble UX5 Aerial Imaging Solution User Guide 794 Completing a Flight

The Dashboard tab with an example flight is shown below:

You must use the Aerial Imaging software on the Tablet to monitor the unmanned aircraft during the entire flight:

l The trajectory ofthe unmanned aircraft on the map must be close to the programmed flight path.

l Monitor the strength ofthe communication link

.

l Monitor the number of usable satellites

.
l No signal: No GPS lock (0–3 satellites)

l 1 signal line: 4–6 satellites

l 2 signal lines: 7 or more satellites

l Monitor the level of power in the UX5 battery. In the battery status bar , the value is expressed as a percentage and as time remaining in minutes.

l Compare the actual flight height with the desired flight height set during mission and flight planning.

l Compare the actual airspeed with the desired airspeed, which is 80 kph (49 mph) during cruise flight. The actual airspeed can be higher than the desired speed when the UX5 is coping with a high head wind. The maximum airspeed is 90 kph (56 mph)

.
l Monitor the throttle. The throttle should be around 30% during cruise flight in normal conditions.

Trimble UX5 Aerial Imaging Solution User Guide 804 Completing a Flight

l Monitor the software for in-flight warnings and errors such as loss of GPS lock and loss of communication link. For more information on these warnings and the appropriate action to take, see Failsafes during flight, page 81 and Errors and warnings, page 99
.
l Monitor the number of flight lines flown against the total number of flight lines (displayed in the status line below the map). The Dashboard tab with an example flight is shown below: 

## Changing the landing parameters during flight If conditions change during the flight, it may be advisable to alter the landing parameters set in the flight plan while the UX5 is still in flight. Note – Once you confirm the landing, you cannot change the landing parameters. To change the landing parameters: 1. Select the Flights tab. The Flights tab appears to the left ofthe Dashboard tab. 2. Tap beside Landing

. 3. Depending on the situation, do one ofthe following:

l If the wind direction has changed and the landing clearances are not jeopardized, rotate the landing heading ofthe current landing accordingly.

l If there is a sudden obstacle in the clearance zone ofthe current landing and you have defined an alternative landing location that is clear from obstacles, tap the landing pin on the map or use the drop-down menu in the Landing properties to select this location. Adapt the landing heading according to the actual wind direction. Note – For the current and any alternative landing setup, it is possible to change any other parameters. However, this requires more effort and time which you may not have. Make sure that if you change the landing location, the location is GPSfixed. For more information, see Setting the landing properties, page 39
. 

## Failsafes during flight The following failsafe mechanisms activate when a technical issue occurs that reduces the safe behavior ofthe unmanned aircraft:

l Loss of GPS lock during flight

l Loss of communication link during flight

l Overspeed protection

Trimble UX5 Aerial Imaging Solution User Guide 814 Completing a Flight



### Loss of GPS lock during flight If the unmanned aircraft does not receive GPS communications for a period of 4 seconds, then a notification appears on the Tablet, and the following automatic failsafe mechanism is activated: 1. The unmanned aircraft banks at an angle of 25° while orbiting at its current location for 20 seconds. If the unmanned aircraft successfully reacquires GPS lock, then it flies to the specified landing location and begins a normal landing sequence. 2. If the unmanned aircraft is unable to reacquire GPS lock, then it activates the Flight Termination System (FTS). During FTS: a. The motor powers down and the speed lowers to 70 kph (43 mph)

. b. The unmanned aircraft orbits down in 200 m (656 ft) diameter circles until it reaches a height of 7 m (23 ft)

. Note – During FTS without GPS lock, the unmanned aircraft attempts to circle but the outcome is elliptical circles as the unmanned aircraft is subject to wind drift.
c. The unmanned aircraft levels its wings, slows, and glides to the ground. 

### Loss of communication link during flight If the unmanned aircraft does not receive a communication packet for the time specified in the Communication timeout field in the Autopilot settings group ofthe Settings screen, or if the communication link is poor and communication packets are being received intermittently, then a notification appears on the Tablet and the unmanned aircraft flies to the specified landing location and begins a normal landing sequence. Unlike a normal landing, you are not prompted to confirm landing before the final leg ofthe landing. An audible sound indicates that the UX5 is about to land. If communication resumes during this automatic failsafe mechanism, the unmanned aircraft continues the landing sequence. 

### Overspeed protection If the unmanned aircraft detects a steep and fast decline, it will maximize drag to minimize the impact on the ground. The aircraft will descend in a "flat-spin"-like flight trajectory. 

## Handling emergencies during flight This topic describes typical emergency scenarios that may occur when the UX5 is in flight. For all scenarios, you must assess the situation before taking action. Take into account your location (that is, the location ofthe GCS) and the current location, course, and speed ofthe UX5. Note – Ifthe situation is too critical (for example, fast moving aircraft) tap and when prompted confirm Flight Termination System (FTS) activation to immediately abort the flight and put the UX5 in an orbit toward the ground.

2. Tap to move the UX5 to a safe position. Tap in the message box on the map to cancel the pattern and continue mapping. The approaching aircraft intends to land. A landing aircraft has priority over an UX5

at all times. Never assume that the aircraft has noticed the UX5. Take the necessary safety measures depending on the situation. Tap in the message box on the map to cancel the pattern and continue mapping. Occasionally other objects such as birds enter the zone of operation. Assess the situation and try to avoid collisions using the methods described above. If a collision does occur, immediately tap in the Aerial Imaging software and if prompted, confirm FTS activation to abort the flight. Once the UX5 has landed, carefully check equipment for damage.

Trimble UX5 Aerial Imaging Solution User Guide 834 Completing a Flight



### Other types of emergency In case of other types of emergency, take the recommended action.
Scenario Action Engine failure is rare but may occur. The following parameters in the Aerial Imaging software indicate engine failure:

l Altimeter decreases

l Battery voltage increases

l Throttle percentage increases until 100% 1. Assess the situation. 2. Tap to immediately terminate the flight. If no button is tapped, the UX5 glides downward, following the flight plan.

Aerial Imaging software freezes or crashes on the GCS when the UX5 is in the air. Immediately restart the software. If you are unable to restart the software, restart the GCS and then restart the Aerial Imaging software. After restarting the software: 1. Go to the Projects screen and open the project for the flight in progress. 2. In the Flights tab, select the flight in progress. 3. Select the Flight checklist tab. When connecting to the autopilot, a message asks if the aircraft is already in the air. 4. Tap to confirm. The Aerial Imaging software downloads the existing flight plan from the eBox and enables you to continue the flight. 

## Emergency software commands The Dashboard tab ofthe Aerial Imaging software provides several buttons that enable you to manually interrupt the pre-programmed flight plan while the unmanned aircraft is in the air. Use these commands to take evasive action if required. Note – Tapping any button in this screen overrides any previous command. Note – The only button available when the UX5 is below 50 m (164ft) during takeoffis

.

Trimble UX5 Aerial Imaging Solution User Guide 844 Completing a Flight



### Land Use the button when the flight must be terminated and there is time and space for a pre-planned landing. When you tap , the unmanned aircraft immediately terminates its flight plan and initiates a normal landing sequence. It flies at the desired flight height to the entry point which is located 300 m (984 ft) from the landing location. If the Land command is initiated during the transition between blocks which are at different heights, the desiredflight height is the height ofthe next block. If the flight height ofthe next block is:

l lower than the previous block, the aircraft flies to the landing entry point while descending

.
l higher than the previous block, the aircraft flies to the landing entry point while ascending

. When the aircraft has reached the landing entry point but is not yet at a height of 75 m (246 ft) + the landing offset, it starts circling downward in 200 m (656 ft) diameter circles until it reaches a height of 75 m (246 ft) + the landing offset.

### FTS Activate the Flight Termination System (FTS) when the UX5 must be removed from the air as quickly as possible. The button can be used during takeoff, cruise flight, and landing. To activate the FTS, tap and if prompted, confirm FTS activation in the message box on the map. Note – Ifyou do not tap in the message box, the UX5 continues theflight. Note – Confirmation is always required, except during takeoffwhen the UX5 is still below 25 m (82ft)

. The unmanned aircraft immediately aborts the flight. During cruise flight, this involves: 1. The motor powers down and the speed lowers to 70 kph (43 mph)

. 2. The unmanned aircraft orbits down in 200 m (656 ft) diameter circles until it reaches a height of

Trimble UX5 Aerial Imaging Solution User Guide 874 Completing a Flight

10 m (33 ft)

. 3. The unmanned aircraft levels its wings, slows, and glides to the ground. If you activate FTS when the unmanned aircraft is at a height of less than 25 m (82 ft)

– that is, during takeoff or landing

– then the unmanned aircraft slows to 60 kph (37 mph) and flies downward in a straight line at the current heading until it glides to the ground. 

### Abort Note – The button is available only during thefinal leg ofthe landing when the aircraft is more than 15 m (49ft) above ground. Make sure you consider the obstacle clearancesfor the Abort manoeuvre before you tap
. For more information, see Obstacle clearancesfor landing, page 35

. Use the button to abort the landing. When you tap , the unmanned aircraft climbs to 75 m (246 ft) in the direction ofthe landing heading and then turns to the landing entry point to start the landing circuit again. To land you must tap in the message box on the map again. 

## Dealing with a crash A crash is an accident associated with the operation of an aircraft in which:

l a person is fatally or seriously injured

l the aircraft sustains damage or structural failure

l the aircraft is missing or completely inaccessible Note – A landing on the intended landing site that causes damage to the aircraft due to the landing surface cannot be seen as a crash. 1. If a crash occurs which causes injuries or death, you must: a. Contact the emergency services. b. Help where necessary, without risking your own life.
c. Make a perimeter around the accident. Make sure no evidence disappears. d. Notify your civil aviation authority (CAA). 2. If a crash occurs which causes damage to another object:
a. Contact the emergency services when necessary (for example, if gas, electricity, or water supplies are affected). b. Contact the owners ofthe object that is hit.
c. Notify your civil aviation authority. 3. Take pictures ofthe crash site. Download the data files from the GCS and send all data and pictures to your Trimble distributor.

# Landing the UX5

CAUTION – It is your responsibility to ensure the safety of the unmanned aircraft during landing. To do this you must:

– Have visual contact with the unmanned aircraft at all times.

– Observe the zone of operation for the unmanned aircraft and look out for other aerial objects.

– Ensure obstacle clearance.

– Locate the unmanned aircraft on the Tablet screen.

WARNING – Make sure there are no people or obstacles near the landing zone. Failure to do so could result in serious personal injury and damage to the rover. After passing the last waypoint on the scan lines, the UX5 terminates its flight plan and initiates a normal landing sequence. It flies at cruise height to the entry point which is located 300 m (984 ft) from the landing location. It starts circling downward in 200 m (656 ft) diameter circles until it reaches a height of 75 m (246 ft)

. It keeps circling in left or right circles, depending on the direction specified in the Aerial Imaging software, until you tap in the message box on the map. To complete the landing, tap in the message box on the map. The UX5 finishes its current circle until it reaches the intersection with the landing direction and then it starts the final leg ofthe landing.

Trimble UX5 Aerial Imaging Solution User Guide 894 Completing a Flight

The image below shows the linear landing circuit using a landing orientation set to right turns.



## Locating the UX5 after landing If the UX5 has landed somewhere in the field and you are not able to visually locate it, you can track it using the tracking system receiver. 1. On the receiver, press and hold the On/Off key for three seconds to power on the receiver. 2. Press the Menu/OK key to enter the menu. 3. Select the transmitter you want to track down using the Scan key and then press the Menu/OK key to confirm. 4. Fold out the four antennas on the receiver and then place the receiver on the palm of your hand, taking care not to touch any ofthe antennas. 5. Increase the gain as much as possible using the Increase key. 6. To pick up the first signal pulses, hold the receiver in front of you at high level and slowly turn 360°, scanning the horizon with the antenna. Tip – Make sure the internal antenna is selected. The range of the receiver is wider if you track from an elevation. Always hold the receiver in front of you so that the receiver can distinguish between incoming signals from the front and the back.

Trimble UX5 Aerial Imaging Solution User Guide 904 Completing a Flight

Each received signal pulse and its strength are shown on the transmitter bar/received signal strength indicator and indicated with an audible signal. 7. Scan the area to determine the direction with the highest signal strength. If the signal strength is the same in all directions, reduce the gain using the Decrease key until the received signal strength is halfthe transmitter bar and then repeat the scan. 8. Follow the determined direction. Repeat the scan at intervals to verify the direction you need to head in to locate the UX5. Note – Ifyou experience difficultiesfinding the roverfollowing one direction, try doing the scanfrom a different location and locating the cross-section between the new and previouslyfound direction. For more information on using the tracker system, refer to the user documentation for the tracker transmitter and receiver. 

# Completing the post-flight checklist
1. After the UX5 has successfully landed, tap
. 2. A message warns that the UX5 should be on the ground. Do one ofthe following:

l If the UX5 is not on the ground, tap
. You will return to the flight monitoring screen.

. The UX5 goes into standby mode and the post-flight checklist appears. 3. Remove the download port cap from the eBox and then attach the download cable to the eBox and the modem. 4. Click

. The software detects the cable connection and automatically starts downloading the log files from the eBox to the Tablet. Note – Ifthere is an issue with the cable connection, the post- flight checklist returns to the previous screen. Detach and then reattach the cable and then click

. 5. When prompted, disconnect the download cable and then reattach the download port cap to the eBox. 6. When prompted, remove the camera from the unmanned aircraft. Trimble recommends deleting the test images taken on the ground from the SD card. Verify that the number of images taken during the flight are equal to the amount of shutter commands recorded in the flight log. If you have not deleted the test images from the SD card, there will be a mismatch between the number of images and the number of shutter commands and you will need to correct this. For more information, see Exporting flight data for processing, page 96
. Note – Ifyou have imagesfrom more than oneflight on the camera, you may need to remove the SD cardfrom the camera, insert it into the Tablet, and then use Windows Explorer to navigate to the correctfolder on the SD card to view the number ofimages takenfor theflight. To do this you will

Trimble UX5 Aerial Imaging Solution User Guide 914 Completing a Flight

need a USB to SD card reader or an external storage device. For more information, see Locating your equipment, page 60

. 7. Select the check box for the block(s) that were successfully mapped during the flight. 8. Tap to close the post-flight checklist and return to the Flights tab. The status ofthe flight changes to: Flown, log files downloaded and settings frozen. To redo this flight, make a copy ofthe flight. The settings ofthe new flight are editable. In the Blocks tab, one ofthe following icons appears next to the block name in the block list:

l Successfully mapped and settings frozen.

l Not successfully mapped and settings frozen. If the log files were downloaded the icon appears next to the block number on the map. A frozen block can still be scheduled in other flights. It will be flown again with the same settings. To map the block with different settings, make a copy ofthe block and change the settings as required. 

# Disassembling the launcher
For safe disassembly ofthe launcher, refer to the Trimble UX5 Launcher Quick Start Guide

. 1. If you have not yet released the tension on the launcher cord, then do so now. To release the tension, release the force with the crank very gently while pulling the release handles in the front ofthe launcher upward. This is safest done with two people, with one person carefully winding the crank counter-clockwise to counteract the force on the elastics.

2. Remove the lock pin on the launch dock and detach the launcher cord. 3. Using the crank, tighten the launcher cord so that most ofthe cord is in the launch slide but the end remains out. Remove the crank.

Trimble UX5 Aerial Imaging Solution User Guide 1237 Specifications and Settings 

## First aid measures In case of battery rupture or explosion, evacuate personnel from contaminated area and provide maximum ventilation to clear out fumes/gases. In all cases where first aid is applied, seek medical attention. Eye contact

l Flush with plenty of water (eyelids held open) for at least 15 minutes. Skin contact

l Remove all contaminated clothing and flush affected areas with plenty of water and soap for at least 15 minutes.

l Do not apply greases or ointments. Ingestion

l Dilute by giving plenty of water and get immediate medical attention.

l Make sure that the victim does not aspirate vomited material by use of positional drainage.

l Make sure that mucus does not obstruct the airway.

l Do not give anything by mouth to an unconscious person. Inhalation

l Remove to fresh air and ventilate the contaminated area.

l Give oxygen or artificial respiration if needed. 

## Fire fighting measures Fire and explosion hazard The battery can leak and/or spout vaporized or decomposed and combustible electrolyte fumes in case of exposure above 70 °C (158 °F) resulting from inappropriate use or the environment. Cells or batteries may flame or leak potentially hazardous organic vapors if exposed to excessive heat or fire. Fire, excessive heat, or over voltage conditions may produce hazardous decomposition products. Damaged or opened cells or batteries can result in rapid heating and the release of flammable vapors. Vapors may be heavier than air and may travel along the ground or be moved by ventilation to an ignition source and flash back Fire, excessive heat, or over voltage conditions may produce hazardous decomposition products.

Trimble UX5 Aerial Imaging Solution User Guide 1247 Specifications and Settings

Use a positive pressure self-contained breathing apparatus if batteries are involved in a fire. Full protective clothing is necessary. During water application, caution is advised as burning pieces of flammable particles may be ejected from the fire. 

### Extinguishing media
Suitable: CO2

Dry chemical or foam extinguishers Not to be used: Type D extinguishers 

### Special exposure hazards Following cell overheating due to external source or due to improper use, electrolyte leakage or battery container rupture may occur and release inner component/material in the environment. Eye contact: The electrolyte solution contained in the battery is irritant to ocular tissues.
Skin contact: The electrolyte solution contained in the battery causes skin irritation. Ingestion: The ingestion of electrolyte solution causes tissue damage to throat and gastro/respiratory tract. Inhalation: Contents of a leaking or ruptured battery can cause respiratory tract, mucus, membrane irritation and edema. 

### Special protective equipment Use self-contained breathing apparatus to avoid breathing irritant fumes. Wear protective clothing and avoid body contact with electrolyte solution. 

## Accidental release measures The material contained within the batteries would only be expelled under abusive conditions. Using shovel or broom, cover battery or spilled substances with dry sand or vermiculite, place in approved container (after cooling if necessary) and dispose in accordance with local regulations. 

## Handling and storage The batteries should not be opened, destroyed or incinerated since they may leak or rupture and release in the environment the ingredients they contain.

Trimble UX5 Aerial Imaging Solution User Guide 1257 Specifications and Settings



### Handling Batteries are designed to be recharged. However, improperly charging a cell or battery may cause the cell or battery to flame. Use only approved chargers and procedures. Never disassemble a battery or bypass any safety device. Do not crush, pierce, short (+) and (-) battery terminals with conductive (i.e. metal) goods. Do not directly heat or solder. Do not throw into fire. Do not mix batteries of different types and brands. Do not mix new and used batteries. Keep batteries in non conductive (i.e. plastic) trays. 

### Storage Do not store batteries above 60 °C (140 °F) or below

-20 °C (-4 °F)

. Store batteries in a cool (below 30 °C/86 °F)), dry area that is subject to little temperature change. Elevated temperatures can result in reduced battery service life. Battery exposure to temperatures in excess of 130 °C (266 °F) will result in the battery venting flammable liquid and gases. Batteries should be separated from other materials and stored in a noncombustible, well ventilated, sprinkler-protected structure with sufficient clearance between walls and battery stacks. Do not store batteries in a manner that allows terminals to short circuit. Extended short-circuiting creates high temperatures in the cell. High temperatures can cause burns in skin or cause the cell to flame. Avoid reversing battery polarity within the battery assembly. To do so may cause cell to flame or to leak. Do not place batteries near heating equipment, nor expose to direct sunlight for long periods. 

### Other Follow manufacturers recommendations regarding maximum recommended currents and operating temperature range. Applying pressure on deforming the battery may lead to disassembly followed by eye, skin and throat irritation.

Trimble UX5 Aerial Imaging Solution User Guide 1267 Specifications and Settings 

## Exposure controls and personal protection No engineering controls are required for handing batteries that have not been damaged. Respiratory protection: Not necessary under normal use.

In case of battery rupture, use self contained full-face respiratory equipment. Hand protection: Not necessary under normal use.

Use gloves if handling a leaking or ruptured battery. Eye protection: Not necessary under normal use.

Wear safety goggles or glasses with side shields if handling a leaking or ruptured battery. Skin protection: Not necessary under normal use.

Use rubber protective working in case of handling of a ruptured battery.

## The Extent of Relief GDA Seeks and the Reason GDA Seeks the Relief

1. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 61.113(a) Relief from Section 61.113(a), entitled Private pilot privileges and limitations: Pilot in command, is requested to the extent necessary to allow a PIC holding a private pilot certificate and an airman medical certificate, and who has completed the Trimble UX5 UAS training requirements, to conduct the proposed UAS flight operations for compensation. This relief is requested since the limitation set forth in Section 61.113(a) states thatno person who holds a private pilot certificate may act as pilot in command of an aircraft that is carrying passengers or property for compensation or hire; nor may that person, for compensation or hire, act as pilot in command of an aircraft. GDA agrees that an equivalent level of safety will be maintained because no PIC will be allowed to operate the Trimble UX5 unless that PIC has met certain flight-hour requirements. The PIC will demonstrate the ability to safely operate the Trimble UX5 UAS in a manner consistent with the operations specifications as set forth herein, including evasive and emergency maneuvers, as well as maintaining appropriate distances from people, vessels, vehicles and structures. Further, GDA proposes that the additional airmanship experience of a commercially certified pilot would be unnecessary for the GDA’s specific proposed operations.

2. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.7(a) Relief from Section 91.7(a), entitled Civil aircraft airworthiness, is requested to the extent required to allow GDA to determine thatthe Trimble UX5 UAS is in an airworthy condition prior to every flight by ensuring that the UAS is in compliance with the Trimble UX5

### Aerial Imaging Solution User Guide and Maintenance, attached as Appendix B and C, respectively. GDA seeks the requested relief because the Trimble UX5 UAS does not require an airworthiness certificatein accordance with 14 C.F.R. Part21, Subpart H. Therefore, GDA will ensure that the Trimble UX5 UAS is in an airworthy condition based upon its compliance with the operating documents prior to every flight, and as stated in the conditions and limitations (Appendix D).
3. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.119(c) Relief from Section 91.119(c), entitled Minimum safe altitudes: (c) Over other than congested areas, is required because all proposed operations of the Trimble UX5 UAS will take place at an altitude at or below 400 feet AGL. The relief is requested since the limitations set forth in Section 91.119(c) state that no person may operate an aircraft below 500 feet above the surface. As set forth more fully below, GDA submitsthat a level of safety equivalent to Section 91.119(c) will be maintained because operations will be conducted in areas with controlled access and GDA will operate the Trimble UX5 UASunder the safety provisions contained within this petition and the Trimble UX5 Aerial Imaging Solutions operating documents. Additionally, relief from Section 91.119(c) isrequested to the extent necessary to allow operations to be conducted closer than 500 feet topersons, vessels, vehicles, or structures. This relief is requested since the limitations set forth in Section 91.119(c) prohibit operating an aircraft closer than 500 feet to a person, vessel, vehicle, or structure. As set forth more fully below, GDA submits an equivalent level of safety will be maintained because operations closer than 500 feet to a person, vessel, vehicle, or st ructure will first require that the operator receive permission from any nonparticipating persons orthe person who owns/controls the property.

4. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.121 Relief from Section 91.121, entitled Altimeter settings, may be required to allow flight operations of the Trimble UX5 UAS, because the UAS’s altitude reporting equipment may be set on the ground to a pressure level of zero feet AGL, rather than localbarometric pressure or field altitude, before each flight. The Trimble UX5 UAS uses GPS equipment, and radio

### communications to transmit altitude information from the UAS to the PIC at the ground control station (GCS). Considering the limited altitude of the proposed operations, relief from 14 C.F.R. § 91.121 is sought to the extent necessary to comply with the applicable conditionsand limitations stated below. As more fully set forth herein, a level of safety equivalent to Section 91.121 will be ensured as the altitude of the Trimble UX5 UAS will be reported to air traffic control (ATC) in feet above ground level (AGL), and GDA will operate the UAS within visual line of sight, at or below 400 feet AGL.
5. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.151(a)(1) Relief from Section 91.151(a)(1) isrequested to the extent required to allow flights of the battery powered Trimble UX5 UAS during daylight hours in visual flight rules (VFR) conditions to continue for a total duration of 35 minutes, with 10 minutes of battery power remaining. GDA seeks the requested relief because without an exemption from Section 91.151(a)(1), the flight time duration of the battery powered Trimble UX5 UAS will be reduced to 20 minutes, which would eliminate the practicality of any aerial acquisition and researchoperations that GDA proposes to conduct pursuant to this Petition. The technical specifications, operating documents, and proposed operating limitations for the Trimble UX5 UAS, ensure that GDA will safely operate the battery powered UAS during daylight hours in VFR conditions for a total duration of 35 minutes, with10 minutes of battery power remaining (i.e., 20 percent remaining).
6. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) Since Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) only apply to aircraft with an airworthiness certificate, GDA requests relief from these Sections because the Trimble UX5 UAS does not require an airworthiness certificate.As set forth more fully below, the Trimble UX5 UAS meets the conditions of Section 333 for operation without an airworthiness certificate. GDA will use technicians to perform maintenance, alterations, or preventive maintenance on the unmanned aircraftsystem using the methods, techniques, and

### practices prescribed in the manufacturer’s maintenance manual. Furthermore, GDA will document and maintain all maintenance records for the Trimble UX5 UAS. 

## The Reasons Why Granting GDA’s Request Would Be in the Public Interest
Granting the present Petition will further the public interest by allowing GDA to safely, efficiently, and economically perform aerial acquisitions and research within the NAS, commercially, in support of government entities, mining and natural resources, industrial and commercial entities, the petroleum industry, and the country’s infrastructure. Additionally, use of the Trimble UX5 UAS will decrease congestion of the NAS, reduce pollution, and provide significant benefits to the economy. The benefits of the proposedoperation of the Trimble UX5 UAS will be realized without implicating any privacy issues.

1. The Public Will Benefit from the Aerial Acquisition and Research Performed GDA submits this Petition to commerciallyoperate the Trimble UX5 UAS and perform aerial acquisition and research within the NAS, in support of government entities, mining and natural resources, indust rial and commercial entities, the petroleum industry, and the country’s infrastructure. The Trimble UX5 UAS will provide safe, efficient, and economical aerial acquisition and research operations to further each of these fields, all of which are critical to the well-being of the general public. The specific operations that GDA will perf orm with the Trimble UX5 UAS demonstrate how the requested exemption will directly benefit the above-referenced industries and the public. In operations involving infrastructure, the aerial acquisition performed by the Trimble UX5 UAS will be used to preview possible sites for construction projects and provide precise topographic information about selected sites. In mining, natural resources, and the petroleum industry, the Trimble UX5 UAS will be used to surveying and planning new worksites, volumetric analysis, and performing right of way analysis. The Trim ble UX5 UAS will also further environmental management by aiding in identifying, developing, and transporting scarce water resources.

### 2. The Public Will Benefit from Decreased Congestion Of The NAS The Trimble UX5 UAS is battery powered and serves as a safe, efficient, and economical alternative to the manned aircraft traditionally utilized to obtain aerial imagery. By reducing the amount of manned aircraft neededto perform aerial acquisitions, an exemption allowing the use of a Trimble UX5 UAS would reduce the amount of manned aircraft in the NAS, reduce noise and air pollution, as well asincrease the safety of life and property in the air and on the ground. Furthermore, by reducing the number of manned aircraft operating in the NAS, congestion around airports caused by arriving and departing aircraft will be reduced. The Trimble UX5 UAS does not require an airport to takeoff or land. Likewise, a reduction of manned aircraft conducting aerial survey missions would result in fewer aircraft that must be handled by air traffic control during the ground, takeoff, departure, arrival, and landing phases of flight operations.

3. The Public Will Benefit from the Safety and Efficiency of the Trimble UX5 UAS Conducting aerial acquisitions with the Trim ble UX5 UAS, instead of manned aircraft, will greatly benefit the public by drastically reducing the levels of air and noise pollution generated during traditional aerial survey flight operations. By using battery power and electric motors, the Trimble UX5 UAS produces no air pollution, and is the most viable environmentally conscious alternative to the cabin class, six cylinder internal combustion twin engine aircraft that are typically utilized for aerial acquisitions, while burning approximately 20-30 gallons per hour of leaded aviation fuel. The Trimble UX5 UAS, while reducing the carbon footprint of aerial acquisitions, also eliminates noise pollution, as its battery powered electric motors produce lower levels of noise then a single engine aircraft. By using the Trimble UX5 UAS to perform aerial acquisitions, the substantial risk to life and property in the air and on the ground, which is usually associated with traditional manned aircraft flight operations, will be substantially reduced or completely eliminated. Aside from the lack of aircrew members located onboard the aircraft, the Trimble UX5 UAS (weighing approximately 5.5 pounds with a wingspan of 39.4 inches and no fuel on board), has less physical potential for collateral damage to lifeand property on the ground, and in the air, compared to the manned aircraft that typically conduct aerial acquisitions (weighing

### approximately 6,500 pounds with a wingspan of approximately 40 feet, a length of 34 feet, and a fuel capacity of 180 gallons).

4. Performing Aerial Acquisition Operations With the Trimble UX5 UAS Will Benefit The Economy In addition to being safe and efficient, the Trimble UX5UAS is also an economical alternative to using manned aircraft to conduct aerial acquisitions. As such, operation of the Trimble UX5 UAS will allow companies like GDA,to remain competitive and contribute to growth of the U.S. economy. Specifically, withthe rising cost of aviation fuel and the Environmental Protection Agency(“EPA”) regulatory actions phasing out leaded fuels, U.S. owned and operated companies must adopt new and alternative technology in order to remain competitive. Operating the battery powered Trimble UX5 UAS will allow companies greater operational flexibility compared to manned aircraft, but provides such flexibility without the high operational cost of a traditional manned aircraft. By operating the Trimble UX5 UAS, companies such as GDA can remain competitive and profitable, and therefore provide greater job stability to employees and contractors, which will ultimately contribute to growth of the U.S.economy. Improved financial performance of U.S. companies, through commercial use of the Trimble UX5 UAS, provides a stable workforce that increases consumer spending;improves local, state, and federal tax revenues; and allows companies to invest in research and development in order to remain competitive.
5. There Are No Privacy Issues Like the manned aerial acquisition flight operations that have been conducted for decades, the proposed operation of the Trimble UX5 UAS will not implicate any privacy issues. Specifically, the Trimble UX5 UAS will be operated in accordance with operating limitations set forth herein and the Federal Aviation Regulations, including the minimum altitude requirements of 14 C.F.R. § 91.119. Most significantly, the Trimble UX5 UAS will not be operated closer than 500 feet to any person, vessel, vehicle, or structure, which is not directly involved in the operation unless certain conditions are met. Further reinforcing the protection of privacy, the Trimble UX5 will be used to fly a preplanned route where the UAS will fly autonomously while the PIC and Observer monitor the

### airspace within the area. The Trimble UX5 will diverge from this flight path only in the event of identifying a hazard or emergency whereby the UASwill be instructed to conduct an immediate landing at a predesignated location. 

## The Reasons Why Granting The Exemption Would Not Adversely Affect Safety

1. Reasons Why the Trimble UX5 UAS Meets the Conditions of the FAA Modernization and Reform Act of 2012 (FMRA) Section 333 In consideration of the size, weight, speed, and limited operating area associated with the unmanned aircraft and its operation, GDA’s operation of the Trimble UX5 UAS meets the conditions of FMRA Section 333, and will not require an airworthiness certificate in accordance with 14 C.F.R. Part 21, Subpart H. Section 333 provides authority for UAS to operate without airworthiness certification and sets forth requirements for considering whether a UAS will create a hazard to users of the NAS or the public, or otherwise pose a threat to national security. In seeking this exemption, GDA submits that the Trimble UX5 UAS can operate safely in the NAS pursuant to FMRA Section 333, as demonstrated by: (a) the characteristics of the Trimble UX5 UAS; (b) the private pilot certification requirement; and (c) the specific operating limitations.
a. The Specifications of the Trimble UX5 UAS Demonstrate Its Safe Characteristics

### ii. The Trimble UX5 UAS Autonomous Flight And Navigation Modes Enable the UAS to Remain within a Defined Operational Area The UX5 has a semi-autonomous navigation and control system comprised of a Ground Control Station (GCS) and auto-pilot system. All flights are pre-programmed with GPS guidance and do not require human intervention. Flight mission area and routing cannot be changed after launch. Flights are not directed by positive manualcontrol, nor are evasive maneuvers. In the case of unplanned events, the operator inputs pre-programmed evasive maneuvers from the control unit and the control unit executes that maneuver. Pre-programmed operator interventions include diversion to the right; initiation of holding at present position; suspension of mission; fly back to launch point; fly to point and hold; abort mission and land; and emergency power cut off and land (Flight Termination System). iii.

### Although a degradation or loss of the control link, and/or degradation or loss of the source of navigation, is unlikely, it is a situation that is well planned for and therefore, is a benign event. The Trimble UX5 UAS is designed for complete autonomy from launch to landing with a line of sight operator inthe loop monitoring the airframe. Automated safety functions and safety enhancing features of the UX5 include the following:

 Auto-pilot detection of lost GPS or of insufficient satellites initiates an immediate spiral landing.

 Low power on the aircraft triggers escalating alarms at GCS at 35% and 10% levels.

 If the auto-pilot detects a lost-link to the GCS for longer than 30 seconds, landing procedure begins.

 The UX5 is inherently unstable, so auto-pilot fail will result in very rapid exit from flight.

 Aircraft has an on-board failsafe that limits speed in the event of dive to approximately 14 m/s.

 The aircraft, weighing less than 6 lbs., fully loaded, is constructed of EPP foam, or similar material which is intended to absorb impact energy.

 The motor is driven by a pulse width modulated signal, not an analog signal.
iv. Mobile Operation of The Trimble UX5 UAS The Trimble UX5 UAS will not be operated in a mobile capacity. All deployments and operations of the UAS will be from a stationaryposition. The only mobility involving the use of the Trimble UX5 will be in acquisition of the UAS and relocation of the catapult launcher.
b. Flight Operations of the Trimble UX5 UAS are Limited to the Line Of Sight of A Certificated Private Pilot in Command with a Safety Observer GDA will only utilize certificated Private Pilots who possess a valid airman medical certificate to act as a pilot in command of the Trimble UX5 UAS. Additionally, a safety observer will assist all pilots during flight operations. Additionally, both the pilot in command and safety observer must complete the Trimble Operators Courseand be tested to

### ensure knowledge of the functions and operationsof the UAS. The training will be conducted at Frontier Precision, a licensed seller and certifier of the Trimble UX5 UAS, located in Denver, CO.

c. Flights will Be Conducted Pursuant toSpecific Operating Limitations. In seeking this exemption, GDA proposes tocommercially operate the Trimble UX5 UAS for the special purpose of conducting aerialacquisitions within the NAS, pursuant to the specific operating limitations set by the FAA for Trimble Navigation Limited. The limitations have been attached as Appendix D.
2. Reasons Why an Exemption from the Requirements of Section 61.113(a) Would Not Adversely Affect Safety GDA submits that an equivalent level of safety established by Section 61.113(a) will be maintained because no PIC will be allowed to operate the Trimble UX5 UAS unless that PIC has demonstrated, through the Trimble UX5 UAS training, that the PIC is able to safely operate the UAS in a manner consistent with this exemption, including evasive and emergency maneuvers and maintaining appropriate distances from people, vessels, vehicles and structures. Considering GDA’s proposed area of operations and the operating limitations (Appendix D); unlike a conventional aircraft that carries a pilot, passengers, and cargo, the Trimble UX5 UAS in this case is remotely controlled withno passengers or property of others on board. Commercial certification would be unnecessary and not improve the capabilities of the PIC for the operation of the Trimble UX5 UAS beyond the private pilot certification and Trimble UX5 UAS training. Additionally, the FAA has previously granted relief from Section 61.113(a), specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11158, 11159, 11160, 11161, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 3. Reasons Why An Exemption from the Requirements of Section 91.7(a) Would Not Adversely Affect Safety The level of safety established by Section 91.7(a) will be maintained because prior to every flight, GDA will ensure that the Trimble UX5UAS is in an airworthy condition and safe for flight based upon the Trimble UX5 UAS’s compliance by conducting a pre-flight check before each operation and following its operatingdocuments (i.e., the Trimble UX5 Aerial Imaging Solution User Guide, and the Trimble UX5 Aerial Imaging Solution Maintenance Guide) and as stated in the conditions and limitations. Additionally, the FAA has previously granted relief from Section 91.7(a), specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).
4. Reasons Why An Exemption From The Requirements Of Section 91.119(c) Would Not Adversely Affect Safety
Section 91.119 establishes safe altitudes for operation of civil aircraft. Specifically, 91.119(c) limits aircraft flying over areas other than congested areas to an altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet toany person, vessel, vehicle, or structure. As set forth herein, the UX5 will never operate at higher than 400 feet AGL. It will, however, be operated to avoid congested or populated areas that are depicted in yellow on VFR sectional - 5 - charts. Because aerial survey work must be accomplished at relatively low altitudes and at altitudes less than 500 feet AGL, an exemption from Section 91.119(c) is needed. The equivalent level of safety will be achieved given the size, weight, speed, and material with which the UX5 is built. Also, no flight will be taken without the permission of the land owner or those who control the land. Because of the advance notice to the landowner, all affected individuals will be aware of the survey flights. Compared to aerial survey operations

### conducted with aircraft or rotorcraft weighing far more than 5.5 lbs. and carrying flammable fuel, any risk associated with these operations will be far less than those currently allowed with conventional aircraft operating at or below 500 feetAGL. Indeed, the low-altitude operations of the UAS will maintain separation between these small-UAS operations and the operations of conventional aircraft that must comply with Section 91.119. The FAA has previously granted relief from Section 91.119(c) specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11111, 11112, 11114, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11184, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).
5. Reasons Why an Exemption from the Requirements of Section 91.121 Would Not Adversely Affect Safety The equivalent level of safety established by Section 91.121 will be maintained because the altitude of the Trimble UX5 UAS will be reported to air traffic control (ATC) in feet above ground level (AGL), and GDA will operate the UAS within visual line of sight, at or below 400 feet AGL. Furthermore, the altitude information of the Trimble UX5 UAS will be provided to the PIC via the GPS equipment, and radio communications which transmits altitude information to the control system. Prior to each flight, a zeroaltitude initiation pointis established at ground level. The FAA has previously granted relief from Section 91.121 specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 6. Reasons Why an Exemption from the Requirements of Section 91.151(a) Would Not Adversely Affect Safety This regulation prohibits an individual from beginning “a flight in an airplane under VFR conditions unless (considering wind and forecast weather conditions) there is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed – (1) During the day, to fly after that for at least 30 minutes; or (2) At night, to fly after that for at least 45 minutes.” The UX5 batteries provide approximately 50 minutes of powered flight. Without an exemption from § 14 CFR 91.151, the UAS’s flights would be limited to approximately 20 minutes in length. Given the limitations on its proposed operations and the location of those proposed operations, a longer time frame for flight in daylight VFR conditions is reasonable. GDA believes that an exemption from 14 CFR § 91.151(a) is safe and within the scope of a prior exemption. Operating the small UAS, without 30 minutes of reserve fuel does not engender the type of risks thatSection 91.151(a) was meant to prevent given the size and speed at which the UAS operates. The fact that it carries no pilot, passenger, or cargo also enhances its safety. Additionally, limiting UX5 f lights to 20 minutes would greatly reduce their utility. In the unlikely event that the UX5 should run out of fuel, it would simply land. Given its weight and construction material, the risks are less thancontemplated by the current regulation. GDA believes that an equivalent level of safety can be achieved by maintaining 10 minutes of reserve fuel (battery power), which, allowing 40 minutes of flight time, would be more than adequate to return the UAS to its planned landing zone from anywhere in its operating area. Due to the loss of utility and difficulty of maintaining line of sight of the Trimble UX5 UAS, GDA will not operate the UAS during nighttime operations. The FAA has previously granted relief from Section 91.151, specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 8811, 10808, 10673, 11042, 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 7. Reasons Why An Exemption From The Requirements Of Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), And 91.417(a) & (b) Would Not Adversely Affect Safety Section 91.405(a) requires that an aircraft operator or owner “shall have that aircraft inspected as prescribed in subpart E of this partand shall between required inspections, except as provided in paragraph (c) of this section, have discrepancies repairedas prescribed in part 43 of this chapter . . . .” Section 91.407 similarly makes reference to requirements in Part 43; Section 91.409(a)(2) requires an annual inspection for the issuance of an air worthiness certificate. Section 91.417(a) requires the owner or operator to keep records showing certain maintenance work that has been accomplished by certificated mechanics, under Part 43, or licensed pilots and records of approval of the aircraft for return to service. Maintenance of the UX5 will be accomplished by the owner/operator pursuant to the manuals, such as Exhibit 3, provided by Trimble. An equivalent level of safety will be achieved because the UAS is small in size,will carry no external payload, will operate only in restricted predetermined areas and is not a complex mechanical devise. As provided in the attached Maintenance Manual and the Safety Checklist, which were reviewed as part of Trimble’s SAC application, the operator of UX5 will ensure that the UAS is in working order prior to initiating flight, perform required maintenance, and keep a log of any maintenance that is performed. Moreover, the operator is the person most familiar withthe aircraft and is best suited to maintain the aircraft in an airworthy condition and toensure an equivalent level of safety. The UX5’s Maintenance Manual provides for replacement of the airframe every 50 hours of flight. This will ensure an equivalent level of safety to the maintenance requirements in Part 91. In addition, between such air frame replacements, should a mechanical issue arise, the aircraft will either return to its launch site or immediately land. The FAA has previously granted relief specific to UAS in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188,11189, 11191, 11192, 11193, 11194 ,11195, 11204, 11206, 11208, 11209).

## A Summary That Can Be Published in The Federal Register,stating: The Rules From Which GDA Seeks Exemption: GDA Engineers seeks exemption from the requirements of 14 C.F.R. Sections 61.113(a), 91.7(a), 91.119(c), 91.121, 91.151(a)(1), 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b).

## The Extent of Relief GDA Seeks and the Reason GDA Seeks the Relief

1. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 61.113(a) Relief from Section 61.113(a), entitled Private pilot privileges and limitations: Pilot in command, is requested to the extent necessary to allow a PIC holding a private pilot certificate and an airman medical certificate, and who has completed the Trimble UX5 UAS training requirements, to conduct the proposed UAS flight operations for compensation. This relief is requested since the limitation set forth in Section 61.113(a) states thatno person who holds a private pilot certificate may act as pilot in command of an aircraft that is carrying passengers or property for compensation or hire; nor may that person, for compensation or hire, act as pilot in command of an aircraft. GDA agrees that an equivalent level of safety will be maintained because no PIC will be allowed to operate the Trimble UX5 unless that PIC has met certain flight-hour requirements. The PIC will demonstrate the ability to safely operate the Trimble UX5 UAS in a manner consistent with the operations specifications as set forth herein, including evasive and emergency maneuvers, as well as maintaining appropriate distances from people, vessels, vehicles and structures. Further, GDA proposes that the additional airmanship experience of a commercially certified pilot would be unnecessary for the GDA’s specific proposed operations.

2. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.7(a) Relief from Section 91.7(a), entitled Civil aircraft airworthiness, is requested to the extent required to allow GDA to determine thatthe Trimble UX5 UAS is in an airworthy condition prior to every flight by ensuring that the UAS is in compliance with the Trimble UX5

### Aerial Imaging Solution User Guide and Maintenance, attached as Appendix B and C, respectively. GDA seeks the requested relief because the Trimble UX5 UAS does not require an airworthiness certificatein accordance with 14 C.F.R. Part21, Subpart H. Therefore, GDA will ensure that the Trimble UX5 UAS is in an airworthy condition based upon its compliance with the operating documents prior to every flight, and as stated in the conditions and limitations (Appendix D).
3. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.119(c) Relief from Section 91.119(c), entitled Minimum safe altitudes: (c) Over other than congested areas, is required because all proposed operations of the Trimble UX5 UAS will take place at an altitude at or below 400 feet AGL. The relief is requested since the limitations set forth in Section 91.119(c) state that no person may operate an aircraft below 500 feet above the surface. As set forth more fully below, GDA submitsthat a level of safety equivalent to Section 91.119(c) will be maintained because operations will be conducted in areas with controlled access and GDA will operate the Trimble UX5 UASunder the safety provisions contained within this petition and the Trimble UX5 Aerial Imaging Solutions operating documents. Additionally, relief from Section 91.119(c) isrequested to the extent necessary to allow operations to be conducted closer than 500 feet topersons, vessels, vehicles, or structures. This relief is requested since the limitations set forth in Section 91.119(c) prohibit operating an aircraft closer than 500 feet to a person, vessel, vehicle, or structure. As set forth more fully below, GDA submits an equivalent level of safety will be maintained because operations closer than 500 feet to a person, vessel, vehicle, or st ructure will first require that the operator receive permission from any nonparticipating persons orthe person who owns/controls the property.

4. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.121 Relief from Section 91.121, entitled Altimeter settings, may be required to allow flight operations of the Trimble UX5 UAS, because the UAS’s altitude reporting equipment may be set on the ground to a pressure level of zero feet AGL, rather than localbarometric pressure or field altitude, before each flight. The Trimble UX5 UAS uses GPS equipment, and radio

### communications to transmit altitude information from the UAS to the PIC at the ground control station (GCS). Considering the limited altitude of the proposed operations, relief from 14 C.F.R. § 91.121 is sought to the extent necessary to comply with the applicable conditionsand limitations stated below. As more fully set forth herein, a level of safety equivalent to Section 91.121 will be ensured as the altitude of the Trimble UX5 UAS will be reported to air traffic control (ATC) in feet above ground level (AGL), and GDA will operate the UAS within visual line of sight, at or below 400 feet AGL.
5. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.151(a)(1) Relief from Section 91.151(a)(1) isrequested to the extent required to allow flights of the battery powered Trimble UX5 UAS during daylight hours in visual flight rules (VFR) conditions to continue for a total duration of 35 minutes, with 10 minutes of battery power remaining. GDA seeks the requested relief because without an exemption from Section 91.151(a)(1), the flight time duration of the battery powered Trimble UX5 UAS will be reduced to 20 minutes, which would eliminate the practicality of any aerial acquisition and researchoperations that GDA proposes to conduct pursuant to this Petition. The technical specifications, operating documents, and proposed operating limitations for the Trimble UX5 UAS, ensure that GDA will safely operate the battery powered UAS during daylight hours in VFR conditions for a total duration of 35 minutes, with10 minutes of battery power remaining (i.e., 20 percent remaining).
6. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) Since Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) only apply to aircraft with an airworthiness certificate, GDA requests relief from these Sections because the Trimble UX5 UAS does not require an airworthiness certificate.As set forth more fully below, the Trimble UX5 UAS meets the conditions of Section 333 for operation without an airworthiness certificate. GDA will use technicians to perform maintenance, alterations, or preventive maintenance on the unmanned aircraftsystem using the methods, techniques, and

### practices prescribed in the manufacturer’s maintenance manual. Furthermore, GDA will document and maintain all maintenance records for the Trimble UX5 UAS. 

## The Reasons Why Granting GDA’s Request Would Be in the Public Interest
Granting the present Petition will further the public interest by allowing GDA to safely, efficiently, and economically perform aerial acquisitions and research within the NAS, commercially, in support of government entities, mining and natural resources, industrial and commercial entities, the petroleum industry, and the country’s infrastructure. Additionally, use of the Trimble UX5 UAS will decrease congestion of the NAS, reduce pollution, and provide significant benefits to the economy. The benefits of the proposedoperation of the Trimble UX5 UAS will be realized without implicating any privacy issues.

1. The Public Will Benefit from the Aerial Acquisition and Research Performed GDA submits this Petition to commerciallyoperate the Trimble UX5 UAS and perform aerial acquisition and research within the NAS, in support of government entities, mining and natural resources, indust rial and commercial entities, the petroleum industry, and the country’s infrastructure. The Trimble UX5 UAS will provide safe, efficient, and economical aerial acquisition and research operations to further each of these fields, all of which are critical to the well-being of the general public. The specific operations that GDA will perf orm with the Trimble UX5 UAS demonstrate how the requested exemption will directly benefit the above-referenced industries and the public. In operations involving infrastructure, the aerial acquisition performed by the Trimble UX5 UAS will be used to preview possible sites for construction projects and provide precise topographic information about selected sites. In mining, natural resources, and the petroleum industry, the Trimble UX5 UAS will be used to surveying and planning new worksites, volumetric analysis, and performing right of way analysis. The Trim ble UX5 UAS will also further environmental management by aiding in identifying, developing, and transporting scarce water resources.

### 2. The Public Will Benefit from Decreased Congestion Of The NAS The Trimble UX5 UAS is battery powered and serves as a safe, efficient, and economical alternative to the manned aircraft traditionally utilized to obtain aerial imagery. By reducing the amount of manned aircraft neededto perform aerial acquisitions, an exemption allowing the use of a Trimble UX5 UAS would reduce the amount of manned aircraft in the NAS, reduce noise and air pollution, as well asincrease the safety of life and property in the air and on the ground. Furthermore, by reducing the number of manned aircraft operating in the NAS, congestion around airports caused by arriving and departing aircraft will be reduced. The Trimble UX5 UAS does not require an airport to takeoff or land. Likewise, a reduction of manned aircraft conducting aerial survey missions would result in fewer aircraft that must be handled by air traffic control during the ground, takeoff, departure, arrival, and landing phases of flight operations.

3. The Public Will Benefit from the Safety and Efficiency of the Trimble UX5 UAS Conducting aerial acquisitions with the Trim ble UX5 UAS, instead of manned aircraft, will greatly benefit the public by drastically reducing the levels of air and noise pollution generated during traditional aerial survey flight operations. By using battery power and electric motors, the Trimble UX5 UAS produces no air pollution, and is the most viable environmentally conscious alternative to the cabin class, six cylinder internal combustion twin engine aircraft that are typically utilized for aerial acquisitions, while burning approximately 20-30 gallons per hour of leaded aviation fuel. The Trimble UX5 UAS, while reducing the carbon footprint of aerial acquisitions, also eliminates noise pollution, as its battery powered electric motors produce lower levels of noise then a single engine aircraft. By using the Trimble UX5 UAS to perform aerial acquisitions, the substantial risk to life and property in the air and on the ground, which is usually associated with traditional manned aircraft flight operations, will be substantially reduced or completely eliminated. Aside from the lack of aircrew members located onboard the aircraft, the Trimble UX5 UAS (weighing approximately 5.5 pounds with a wingspan of 39.4 inches and no fuel on board), has less physical potential for collateral damage to lifeand property on the ground, and in the air, compared to the manned aircraft that typically conduct aerial acquisitions (weighing

### approximately 6,500 pounds with a wingspan of approximately 40 feet, a length of 34 feet, and a fuel capacity of 180 gallons).

4. Performing Aerial Acquisition Operations With the Trimble UX5 UAS Will Benefit The Economy In addition to being safe and efficient, the Trimble UX5UAS is also an economical alternative to using manned aircraft to conduct aerial acquisitions. As such, operation of the Trimble UX5 UAS will allow companies like GDA,to remain competitive and contribute to growth of the U.S. economy. Specifically, withthe rising cost of aviation fuel and the Environmental Protection Agency(“EPA”) regulatory actions phasing out leaded fuels, U.S. owned and operated companies must adopt new and alternative technology in order to remain competitive. Operating the battery powered Trimble UX5 UAS will allow companies greater operational flexibility compared to manned aircraft, but provides such flexibility without the high operational cost of a traditional manned aircraft. By operating the Trimble UX5 UAS, companies such as GDA can remain competitive and profitable, and therefore provide greater job stability to employees and contractors, which will ultimately contribute to growth of the U.S.economy. Improved financial performance of U.S. companies, through commercial use of the Trimble UX5 UAS, provides a stable workforce that increases consumer spending;improves local, state, and federal tax revenues; and allows companies to invest in research and development in order to remain competitive.
5. There Are No Privacy Issues Like the manned aerial acquisition flight operations that have been conducted for decades, the proposed operation of the Trimble UX5 UAS will not implicate any privacy issues. Specifically, the Trimble UX5 UAS will be operated in accordance with operating limitations set forth herein and the Federal Aviation Regulations, including the minimum altitude requirements of 14 C.F.R. § 91.119. Most significantly, the Trimble UX5 UAS will not be operated closer than 500 feet to any person, vessel, vehicle, or structure, which is not directly involved in the operation unless certain conditions are met. Further reinforcing the protection of privacy, the Trimble UX5 will be used to fly a preplanned route where the UAS will fly autonomously while the PIC and Observer monitor the

### airspace within the area. The Trimble UX5 will diverge from this flight path only in the event of identifying a hazard or emergency whereby the UASwill be instructed to conduct an immediate landing at a predesignated location. 

## The Reasons Why Granting The Exemption Would Not Adversely Affect Safety

1. Reasons Why the Trimble UX5 UAS Meets the Conditions of the FAA Modernization and Reform Act of 2012 (FMRA) Section 333 In consideration of the size, weight, speed, and limited operating area associated with the unmanned aircraft and its operation, GDA’s operation of the Trimble UX5 UAS meets the conditions of FMRA Section 333, and will not require an airworthiness certificate in accordance with 14 C.F.R. Part 21, Subpart H. Section 333 provides authority for UAS to operate without airworthiness certification and sets forth requirements for considering whether a UAS will create a hazard to users of the NAS or the public, or otherwise pose a threat to national security. In seeking this exemption, GDA submits that the Trimble UX5 UAS can operate safely in the NAS pursuant to FMRA Section 333, as demonstrated by: (a) the characteristics of the Trimble UX5 UAS; (b) the private pilot certification requirement; and (c) the specific operating limitations.
a. The Specifications of the Trimble UX5 UAS Demonstrate Its Safe Characteristics

### ii. The Trimble UX5 UAS Autonomous Flight And Navigation Modes Enable the UAS to Remain within a Defined Operational Area The UX5 has a semi-autonomous navigation and control system comprised of a Ground Control Station (GCS) and auto-pilot system. All flights are pre-programmed with GPS guidance and do not require human intervention. Flight mission area and routing cannot be changed after launch. Flights are not directed by positive manualcontrol, nor are evasive maneuvers. In the case of unplanned events, the operator inputs pre-programmed evasive maneuvers from the control unit and the control unit executes that maneuver. Pre-programmed operator interventions include diversion to the right; initiation of holding at present position; suspension of mission; fly back to launch point; fly to point and hold; abort mission and land; and emergency power cut off and land (Flight Termination System). iii.

### Although a degradation or loss of the control link, and/or degradation or loss of the source of navigation, is unlikely, it is a situation that is well planned for and therefore, is a benign event. The Trimble UX5 UAS is designed for complete autonomy from launch to landing with a line of sight operator inthe loop monitoring the airframe. Automated safety functions and safety enhancing features of the UX5 include the following:

 Auto-pilot detection of lost GPS or of insufficient satellites initiates an immediate spiral landing.

 Low power on the aircraft triggers escalating alarms at GCS at 35% and 10% levels.

 If the auto-pilot detects a lost-link to the GCS for longer than 30 seconds, landing procedure begins.

 The UX5 is inherently unstable, so auto-pilot fail will result in very rapid exit from flight.

 Aircraft has an on-board failsafe that limits speed in the event of dive to approximately 14 m/s.

 The aircraft, weighing less than 6 lbs., fully loaded, is constructed of EPP foam, or similar material which is intended to absorb impact energy.

 The motor is driven by a pulse width modulated signal, not an analog signal.
iv. Mobile Operation of The Trimble UX5 UAS The Trimble UX5 UAS will not be operated in a mobile capacity. All deployments and operations of the UAS will be from a stationaryposition. The only mobility involving the use of the Trimble UX5 will be in acquisition of the UAS and relocation of the catapult launcher.
b. Flight Operations of the Trimble UX5 UAS are Limited to the Line Of Sight of A Certificated Private Pilot in Command with a Safety Observer GDA will only utilize certificated Private Pilots who possess a valid airman medical certificate to act as a pilot in command of the Trimble UX5 UAS. Additionally, a safety observer will assist all pilots during flight operations. Additionally, both the pilot in command and safety observer must complete the Trimble Operators Courseand be tested to

### ensure knowledge of the functions and operationsof the UAS. The training will be conducted at Frontier Precision, a licensed seller and certifier of the Trimble UX5 UAS, located in Denver, CO.

c. Flights will Be Conducted Pursuant toSpecific Operating Limitations. In seeking this exemption, GDA proposes tocommercially operate the Trimble UX5 UAS for the special purpose of conducting aerialacquisitions within the NAS, pursuant to the specific operating limitations set by the FAA for Trimble Navigation Limited. The limitations have been attached as Appendix D.
2. Reasons Why an Exemption from the Requirements of Section 61.113(a) Would Not Adversely Affect Safety GDA submits that an equivalent level of safety established by Section 61.113(a) will be maintained because no PIC will be allowed to operate the Trimble UX5 UAS unless that PIC has demonstrated, through the Trimble UX5 UAS training, that the PIC is able to safely operate the UAS in a manner consistent with this exemption, including evasive and emergency maneuvers and maintaining appropriate distances from people, vessels, vehicles and structures. Considering GDA’s proposed area of operations and the operating limitations (Appendix D); unlike a conventional aircraft that carries a pilot, passengers, and cargo, the Trimble UX5 UAS in this case is remotely controlled withno passengers or property of others on board. Commercial certification would be unnecessary and not improve the capabilities of the PIC for the operation of the Trimble UX5 UAS beyond the private pilot certification and Trimble UX5 UAS training. Additionally, the FAA has previously granted relief from Section 61.113(a), specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11158, 11159, 11160, 11161, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 3. Reasons Why An Exemption from the Requirements of Section 91.7(a) Would Not Adversely Affect Safety The level of safety established by Section 91.7(a) will be maintained because prior to every flight, GDA will ensure that the Trimble UX5UAS is in an airworthy condition and safe for flight based upon the Trimble UX5 UAS’s compliance by conducting a pre-flight check before each operation and following its operatingdocuments (i.e., the Trimble UX5 Aerial Imaging Solution User Guide, and the Trimble UX5 Aerial Imaging Solution Maintenance Guide) and as stated in the conditions and limitations. Additionally, the FAA has previously granted relief from Section 91.7(a), specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).
4. Reasons Why An Exemption From The Requirements Of Section 91.119(c) Would Not Adversely Affect Safety
Section 91.119 establishes safe altitudes for operation of civil aircraft. Specifically, 91.119(c) limits aircraft flying over areas other than congested areas to an altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet toany person, vessel, vehicle, or structure. As set forth herein, the UX5 will never operate at higher than 400 feet AGL. It will, however, be operated to avoid congested or populated areas that are depicted in yellow on VFR sectional - 5 - charts. Because aerial survey work must be accomplished at relatively low altitudes and at altitudes less than 500 feet AGL, an exemption from Section 91.119(c) is needed. The equivalent level of safety will be achieved given the size, weight, speed, and material with which the UX5 is built. Also, no flight will be taken without the permission of the land owner or those who control the land. Because of the advance notice to the landowner, all affected individuals will be aware of the survey flights. Compared to aerial survey operations

### conducted with aircraft or rotorcraft weighing far more than 5.5 lbs. and carrying flammable fuel, any risk associated with these operations will be far less than those currently allowed with conventional aircraft operating at or below 500 feetAGL. Indeed, the low-altitude operations of the UAS will maintain separation between these small-UAS operations and the operations of conventional aircraft that must comply with Section 91.119. The FAA has previously granted relief from Section 91.119(c) specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11111, 11112, 11114, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11184, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).
5. Reasons Why an Exemption from the Requirements of Section 91.121 Would Not Adversely Affect Safety The equivalent level of safety established by Section 91.121 will be maintained because the altitude of the Trimble UX5 UAS will be reported to air traffic control (ATC) in feet above ground level (AGL), and GDA will operate the UAS within visual line of sight, at or below 400 feet AGL. Furthermore, the altitude information of the Trimble UX5 UAS will be provided to the PIC via the GPS equipment, and radio communications which transmits altitude information to the control system. Prior to each flight, a zeroaltitude initiation pointis established at ground level. The FAA has previously granted relief from Section 91.121 specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 6. Reasons Why an Exemption from the Requirements of Section 91.151(a) Would Not Adversely Affect Safety This regulation prohibits an individual from beginning “a flight in an airplane under VFR conditions unless (considering wind and forecast weather conditions) there is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed – (1) During the day, to fly after that for at least 30 minutes; or (2) At night, to fly after that for at least 45 minutes.” The UX5 batteries provide approximately 50 minutes of powered flight. Without an exemption from § 14 CFR 91.151, the UAS’s flights would be limited to approximately 20 minutes in length. Given the limitations on its proposed operations and the location of those proposed operations, a longer time frame for flight in daylight VFR conditions is reasonable. GDA believes that an exemption from 14 CFR § 91.151(a) is safe and within the scope of a prior exemption. Operating the small UAS, without 30 minutes of reserve fuel does not engender the type of risks thatSection 91.151(a) was meant to prevent given the size and speed at which the UAS operates. The fact that it carries no pilot, passenger, or cargo also enhances its safety. Additionally, limiting UX5 f lights to 20 minutes would greatly reduce their utility. In the unlikely event that the UX5 should run out of fuel, it would simply land. Given its weight and construction material, the risks are less thancontemplated by the current regulation. GDA believes that an equivalent level of safety can be achieved by maintaining 10 minutes of reserve fuel (battery power), which, allowing 40 minutes of flight time, would be more than adequate to return the UAS to its planned landing zone from anywhere in its operating area. Due to the loss of utility and difficulty of maintaining line of sight of the Trimble UX5 UAS, GDA will not operate the UAS during nighttime operations. The FAA has previously granted relief from Section 91.151, specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 8811, 10808, 10673, 11042, 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 7. Reasons Why An Exemption From The Requirements Of Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), And 91.417(a) & (b) Would Not Adversely Affect Safety Section 91.405(a) requires that an aircraft operator or owner “shall have that aircraft inspected as prescribed in subpart E of this partand shall between required inspections, except as provided in paragraph (c) of this section, have discrepancies repairedas prescribed in part 43 of this chapter . . . .” Section 91.407 similarly makes reference to requirements in Part 43; Section 91.409(a)(2) requires an annual inspection for the issuance of an air worthiness certificate. Section 91.417(a) requires the owner or operator to keep records showing certain maintenance work that has been accomplished by certificated mechanics, under Part 43, or licensed pilots and records of approval of the aircraft for return to service. Maintenance of the UX5 will be accomplished by the owner/operator pursuant to the manuals, such as Exhibit 3, provided by Trimble. An equivalent level of safety will be achieved because the UAS is small in size,will carry no external payload, will operate only in restricted predetermined areas and is not a complex mechanical devise. As provided in the attached Maintenance Manual and the Safety Checklist, which were reviewed as part of Trimble’s SAC application, the operator of UX5 will ensure that the UAS is in working order prior to initiating flight, perform required maintenance, and keep a log of any maintenance that is performed. Moreover, the operator is the person most familiar withthe aircraft and is best suited to maintain the aircraft in an airworthy condition and toensure an equivalent level of safety. The UX5’s Maintenance Manual provides for replacement of the airframe every 50 hours of flight. This will ensure an equivalent level of safety to the maintenance requirements in Part 91. In addition, between such air frame replacements, should a mechanical issue arise, the aircraft will either return to its launch site or immediately land. The FAA has previously granted relief specific to UAS in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188,11189, 11191, 11192, 11193, 11194 ,11195, 11204, 11206, 11208, 11209).

### 1. Operations authorized by this grant of exemption are limited to the following aircraft described in the operating documents, which isthe Trimble UX5 Aerial Imaging Solution, a fixed-wing aircraft weighing approximately 5.5 pounds at maximum gross weight. Proposed operations of any other aircraft will require a new petition or a petition to amend this grant. 2. UAS operations under this exemption are limited to conducting operations for the purpose of aerial acquisitions. 3. The UA may not be flown at an indicated airspeed exceeding 30 knots (i.e., 34.5 mph). 4. The UA must be operated at an altitude of no more than 400 feet above ground level (AGL), as indicated by the procedures specified in the operating documents. All altitudes reported to ATC must be in feet AGL. 5. The UA must be operated within visual line of sight (VLOS) of the PIC at all times. This requires the PIC to be able touse human vision unaided by any device other than corrective lenses, as specified on the PIC’s FAA-issued airman medical certificate. 6. All operations must utilize a visual observer (VO). The VO may be used to satisfy the VLOS requirement as long as the PIC always maintains VLOS capability. The VO and PIC must be able to communicate verbally at all times. Electronic messaging or texting is not permitted during flight operations. The PIC must be designated before the flight and cannot transfer his or her designation for the duration of the flight. 7. The VO must not perform any other duties beyond assisting the PIC with seeing and avoiding other air traffic and other ground based obstacles/obstructions and is not permitted to operate the camera or other instruments. 8. The operating documents and this grant of exemption must be accessible during UAS operations and made available to the Administrator upon request. If a discrepancy exists between the conditions and limitations inthis exemption and the procedures outlined in the operating documents, the conditions and limitations contained in the grant of exemption take precedence and must be followed. Otherwise, the operator must follow the procedures as outlined in its operating documents. The operator may update or revise its operating documents. It is the operator’s responsibility to track such revisions and present updated and revised documents to the Administrator upon request. The operator must also present updated and revised documents if it petitions for extension or amendment to the grant of exemption. If the operator determines that any update or revision would affect the basis upon which the FAA granted the exemption, then the operator must petition for amendment to the grant of exemption. The FAA’s UAS Integration Office (AFS-80) may be contacted if questions arise regarding updates or revisions to the operating documents. 9. Prior to each flight the PIC must inspect the UAS to ensure it is in a condition for safe flight. If the inspection reveals a condition that affects the safe operation of the UAS, the aircraft

### is prohibited from operating untilthe necessary maintenance has been performed and the UAS is found to be in a condition for safe flight. The Ground Control Station must be included in the preflight inspection. All maintenance and alterations must be properly documented in the aircraft records. 10. Any UAS that has undergone maintenance or alterations that affect the UAS operation or flight characteristics, e.g. replacement of a flight critical component, must undergo a functional test flight in accordance with the operating documents. The PIC who conducts the functional test flight must make an entry in the UASaircraft records of the flight. 11. The pre-flight inspection must account for all potential discrepancies, i.e. inoperable components, items, or equipment, not already covered in the relevant preflight inspection sections of the operating documents. 12. The operator must follow the UAS manufacturer’s aircraft/component, maintenance, overhaul, replacement, inspection, and life limit requirements, with particular attention to flight critical components that may not be addressed in the manufacturer’s manuals. 13. The operator must carry out its maintenance, inspections, and record keeping requirements, in accordance with the operating documents. Maintenance, inspection, alterations, and status of replacement/overhaul component parts must be noted in the aircraft records, including total time in service, description of work accomplished, and the signature of the authorized person returning the UAS to service. 14. Each UAS operated under this exemption must comply with all manufacturer Safety Bulletins. 15. The authorized person must make an entry in the aircraft record of the corrective action taken against discrepancies discovered between inspections. 16. The PIC must possess at least a private pilot certificate and at least a current thirdclass medical certificate for all flight operations. The PIC must also meet the flight review requirements specified in 14 C.F.R. § 61.56 in an aircraft in which the PIC is rated on his or her pilot certificate. 17. Prior to operations, the PIC must have completed the operator’s training and currency requirements as prescribed in the operating documents. During that training, the PIC must have accumulated and logged, in a manner consistent with 14 CFR § 61.51(b), the minimum hours prescribed in the operating documents for a UAS pilot operating the make and model of the UAS to be utilized for operations under the exemption. Training, proficiency, and experience-building flights can be conducted under thisgrant of exemption to qualif y the operator’s PIC(s), VO(s) and other essential personnel as defined in the operating documents. However, said training operations may only be conducted during dedicated training sessions. During training,

### proficiency, and experience-building flights the PIC is required to operate the UA with appropriate distances in accordance with 14 CFR § 91.119. 18. The operator may not permit any PIC to operate unless that PIC has demonstrated through the operator’s training and currency requirements that the PIC is able to safely operate the UAS in a manner consistent with how the UAS will be operated under this exemption, including evasive and emergency maneuvers and maintaining appropriate distances from people, vessels, vehicles and structures. 19. UAS operations may not be conducted during night, as defined in 14 C.F.R. § 1.1. All operations must be conducted under visual meteorological conditions(VMC). Flights under special visual flight rules (SVFR) are not authorized. 20. The UA may not operate within 5 nautical miles of an airport reference point as denoted on a current FAA-published aeronautical chart unless a letter of agreement with that airport’s management is obtained, and the operation is conducted in accordance with a NOTAM as required by the operator’s COA. The letter of agreement with the airport management must be made available to the Administrator upon request. 21. The UA may not be operated less than 500 feet below or lessthan 2,000 feet horizontally from a cloud or when visibility is less than 3 statute miles from the PIC. 22. If the UA loses communications or loses its GPS signal, it must return to a predetermined location within the planned operating area and land or be recovered in accordance with the operating documents. 23. The PIC must abort the flight in the event of unpredicted obstacles or emergencies in accordance with the operating documents. 24.

## The Extent of Relief GDA Seeks and the Reason GDA Seeks the Relief

1. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 61.113(a) Relief from Section 61.113(a), entitled Private pilot privileges and limitations: Pilot in command, is requested to the extent necessary to allow a PIC holding a private pilot certificate and an airman medical certificate, and who has completed the Trimble UX5 UAS training requirements, to conduct the proposed UAS flight operations for compensation. This relief is requested since the limitation set forth in Section 61.113(a) states thatno person who holds a private pilot certificate may act as pilot in command of an aircraft that is carrying passengers or property for compensation or hire; nor may that person, for compensation or hire, act as pilot in command of an aircraft. GDA agrees that an equivalent level of safety will be maintained because no PIC will be allowed to operate the Trimble UX5 unless that PIC has met certain flight-hour requirements. The PIC will demonstrate the ability to safely operate the Trimble UX5 UAS in a manner consistent with the operations specifications as set forth herein, including evasive and emergency maneuvers, as well as maintaining appropriate distances from people, vessels, vehicles and structures. Further, GDA proposes that the additional airmanship experience of a commercially certified pilot would be unnecessary for the GDA’s specific proposed operations.

2. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.7(a) Relief from Section 91.7(a), entitled Civil aircraft airworthiness, is requested to the extent required to allow GDA to determine thatthe Trimble UX5 UAS is in an airworthy condition prior to every flight by ensuring that the UAS is in compliance with the Trimble UX5

### Aerial Imaging Solution User Guide and Maintenance, attached as Appendix B and C, respectively. GDA seeks the requested relief because the Trimble UX5 UAS does not require an airworthiness certificatein accordance with 14 C.F.R. Part21, Subpart H. Therefore, GDA will ensure that the Trimble UX5 UAS is in an airworthy condition based upon its compliance with the operating documents prior to every flight, and as stated in the conditions and limitations (Appendix D).
3. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.119(c) Relief from Section 91.119(c), entitled Minimum safe altitudes: (c) Over other than congested areas, is required because all proposed operations of the Trimble UX5 UAS will take place at an altitude at or below 400 feet AGL. The relief is requested since the limitations set forth in Section 91.119(c) state that no person may operate an aircraft below 500 feet above the surface. As set forth more fully below, GDA submitsthat a level of safety equivalent to Section 91.119(c) will be maintained because operations will be conducted in areas with controlled access and GDA will operate the Trimble UX5 UASunder the safety provisions contained within this petition and the Trimble UX5 Aerial Imaging Solutions operating documents. Additionally, relief from Section 91.119(c) isrequested to the extent necessary to allow operations to be conducted closer than 500 feet topersons, vessels, vehicles, or structures. This relief is requested since the limitations set forth in Section 91.119(c) prohibit operating an aircraft closer than 500 feet to a person, vessel, vehicle, or structure. As set forth more fully below, GDA submits an equivalent level of safety will be maintained because operations closer than 500 feet to a person, vessel, vehicle, or st ructure will first require that the operator receive permission from any nonparticipating persons orthe person who owns/controls the property.

4. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.121 Relief from Section 91.121, entitled Altimeter settings, may be required to allow flight operations of the Trimble UX5 UAS, because the UAS’s altitude reporting equipment may be set on the ground to a pressure level of zero feet AGL, rather than localbarometric pressure or field altitude, before each flight. The Trimble UX5 UAS uses GPS equipment, and radio

### communications to transmit altitude information from the UAS to the PIC at the ground control station (GCS). Considering the limited altitude of the proposed operations, relief from 14 C.F.R. § 91.121 is sought to the extent necessary to comply with the applicable conditionsand limitations stated below. As more fully set forth herein, a level of safety equivalent to Section 91.121 will be ensured as the altitude of the Trimble UX5 UAS will be reported to air traffic control (ATC) in feet above ground level (AGL), and GDA will operate the UAS within visual line of sight, at or below 400 feet AGL.
5. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Section 91.151(a)(1) Relief from Section 91.151(a)(1) isrequested to the extent required to allow flights of the battery powered Trimble UX5 UAS during daylight hours in visual flight rules (VFR) conditions to continue for a total duration of 35 minutes, with 10 minutes of battery power remaining. GDA seeks the requested relief because without an exemption from Section 91.151(a)(1), the flight time duration of the battery powered Trimble UX5 UAS will be reduced to 20 minutes, which would eliminate the practicality of any aerial acquisition and researchoperations that GDA proposes to conduct pursuant to this Petition. The technical specifications, operating documents, and proposed operating limitations for the Trimble UX5 UAS, ensure that GDA will safely operate the battery powered UAS during daylight hours in VFR conditions for a total duration of 35 minutes, with10 minutes of battery power remaining (i.e., 20 percent remaining).
6. Extent of Relief GDA Seeks and the Reason GDA Seeks Relief from Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) Since Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) only apply to aircraft with an airworthiness certificate, GDA requests relief from these Sections because the Trimble UX5 UAS does not require an airworthiness certificate.As set forth more fully below, the Trimble UX5 UAS meets the conditions of Section 333 for operation without an airworthiness certificate. GDA will use technicians to perform maintenance, alterations, or preventive maintenance on the unmanned aircraftsystem using the methods, techniques, and

### practices prescribed in the manufacturer’s maintenance manual. Furthermore, GDA will document and maintain all maintenance records for the Trimble UX5 UAS. 

## The Reasons Why Granting GDA’s Request Would Be in the Public Interest
Granting the present Petition will further the public interest by allowing GDA to safely, efficiently, and economically perform aerial acquisitions and research within the NAS, commercially, in support of government entities, mining and natural resources, industrial and commercial entities, the petroleum industry, and the country’s infrastructure. Additionally, use of the Trimble UX5 UAS will decrease congestion of the NAS, reduce pollution, and provide significant benefits to the economy. The benefits of the proposedoperation of the Trimble UX5 UAS will be realized without implicating any privacy issues.

1. The Public Will Benefit from the Aerial Acquisition and Research Performed GDA submits this Petition to commerciallyoperate the Trimble UX5 UAS and perform aerial acquisition and research within the NAS, in support of government entities, mining and natural resources, indust rial and commercial entities, the petroleum industry, and the country’s infrastructure. The Trimble UX5 UAS will provide safe, efficient, and economical aerial acquisition and research operations to further each of these fields, all of which are critical to the well-being of the general public. The specific operations that GDA will perf orm with the Trimble UX5 UAS demonstrate how the requested exemption will directly benefit the above-referenced industries and the public. In operations involving infrastructure, the aerial acquisition performed by the Trimble UX5 UAS will be used to preview possible sites for construction projects and provide precise topographic information about selected sites. In mining, natural resources, and the petroleum industry, the Trimble UX5 UAS will be used to surveying and planning new worksites, volumetric analysis, and performing right of way analysis. The Trim ble UX5 UAS will also further environmental management by aiding in identifying, developing, and transporting scarce water resources.

### 2. The Public Will Benefit from Decreased Congestion Of The NAS The Trimble UX5 UAS is battery powered and serves as a safe, efficient, and economical alternative to the manned aircraft traditionally utilized to obtain aerial imagery. By reducing the amount of manned aircraft neededto perform aerial acquisitions, an exemption allowing the use of a Trimble UX5 UAS would reduce the amount of manned aircraft in the NAS, reduce noise and air pollution, as well asincrease the safety of life and property in the air and on the ground. Furthermore, by reducing the number of manned aircraft operating in the NAS, congestion around airports caused by arriving and departing aircraft will be reduced. The Trimble UX5 UAS does not require an airport to takeoff or land. Likewise, a reduction of manned aircraft conducting aerial survey missions would result in fewer aircraft that must be handled by air traffic control during the ground, takeoff, departure, arrival, and landing phases of flight operations.

3. The Public Will Benefit from the Safety and Efficiency of the Trimble UX5 UAS Conducting aerial acquisitions with the Trim ble UX5 UAS, instead of manned aircraft, will greatly benefit the public by drastically reducing the levels of air and noise pollution generated during traditional aerial survey flight operations. By using battery power and electric motors, the Trimble UX5 UAS produces no air pollution, and is the most viable environmentally conscious alternative to the cabin class, six cylinder internal combustion twin engine aircraft that are typically utilized for aerial acquisitions, while burning approximately 20-30 gallons per hour of leaded aviation fuel. The Trimble UX5 UAS, while reducing the carbon footprint of aerial acquisitions, also eliminates noise pollution, as its battery powered electric motors produce lower levels of noise then a single engine aircraft. By using the Trimble UX5 UAS to perform aerial acquisitions, the substantial risk to life and property in the air and on the ground, which is usually associated with traditional manned aircraft flight operations, will be substantially reduced or completely eliminated. Aside from the lack of aircrew members located onboard the aircraft, the Trimble UX5 UAS (weighing approximately 5.5 pounds with a wingspan of 39.4 inches and no fuel on board), has less physical potential for collateral damage to lifeand property on the ground, and in the air, compared to the manned aircraft that typically conduct aerial acquisitions (weighing

### approximately 6,500 pounds with a wingspan of approximately 40 feet, a length of 34 feet, and a fuel capacity of 180 gallons).

4. Performing Aerial Acquisition Operations With the Trimble UX5 UAS Will Benefit The Economy In addition to being safe and efficient, the Trimble UX5UAS is also an economical alternative to using manned aircraft to conduct aerial acquisitions. As such, operation of the Trimble UX5 UAS will allow companies like GDA,to remain competitive and contribute to growth of the U.S. economy. Specifically, withthe rising cost of aviation fuel and the Environmental Protection Agency(“EPA”) regulatory actions phasing out leaded fuels, U.S. owned and operated companies must adopt new and alternative technology in order to remain competitive. Operating the battery powered Trimble UX5 UAS will allow companies greater operational flexibility compared to manned aircraft, but provides such flexibility without the high operational cost of a traditional manned aircraft. By operating the Trimble UX5 UAS, companies such as GDA can remain competitive and profitable, and therefore provide greater job stability to employees and contractors, which will ultimately contribute to growth of the U.S.economy. Improved financial performance of U.S. companies, through commercial use of the Trimble UX5 UAS, provides a stable workforce that increases consumer spending;improves local, state, and federal tax revenues; and allows companies to invest in research and development in order to remain competitive.
5. There Are No Privacy Issues Like the manned aerial acquisition flight operations that have been conducted for decades, the proposed operation of the Trimble UX5 UAS will not implicate any privacy issues. Specifically, the Trimble UX5 UAS will be operated in accordance with operating limitations set forth herein and the Federal Aviation Regulations, including the minimum altitude requirements of 14 C.F.R. § 91.119. Most significantly, the Trimble UX5 UAS will not be operated closer than 500 feet to any person, vessel, vehicle, or structure, which is not directly involved in the operation unless certain conditions are met. Further reinforcing the protection of privacy, the Trimble UX5 will be used to fly a preplanned route where the UAS will fly autonomously while the PIC and Observer monitor the

### airspace within the area. The Trimble UX5 will diverge from this flight path only in the event of identifying a hazard or emergency whereby the UASwill be instructed to conduct an immediate landing at a predesignated location. 

## The Reasons Why Granting The Exemption Would Not Adversely Affect Safety

1. Reasons Why the Trimble UX5 UAS Meets the Conditions of the FAA Modernization and Reform Act of 2012 (FMRA) Section 333 In consideration of the size, weight, speed, and limited operating area associated with the unmanned aircraft and its operation, GDA’s operation of the Trimble UX5 UAS meets the conditions of FMRA Section 333, and will not require an airworthiness certificate in accordance with 14 C.F.R. Part 21, Subpart H. Section 333 provides authority for UAS to operate without airworthiness certification and sets forth requirements for considering whether a UAS will create a hazard to users of the NAS or the public, or otherwise pose a threat to national security. In seeking this exemption, GDA submits that the Trimble UX5 UAS can operate safely in the NAS pursuant to FMRA Section 333, as demonstrated by: (a) the characteristics of the Trimble UX5 UAS; (b) the private pilot certification requirement; and (c) the specific operating limitations.
a. The Specifications of the Trimble UX5 UAS Demonstrate Its Safe Characteristics

The Trimble UX5 UAS does not create a hazard to users of the NAS or the public, or otherwise pose a threat to national security considering its size, weight, speed, and operational capability.

### i. Technical Specifications of the Trimble UX5 UAS PERFORMANCE SPECIFICATIONS • Maximized image footprint without compromising resolution, obtained with a custom wide-angle lens and APSC-type sensor. • Maximized coverage per flight and per hour due to large image footprint, sharp turning capability and high cruise speed. • Reversed thrust technology for a short and steep landing circuit. • Powerful propulsion system for steep climbs and high altitude flights. • High airframe service life due to wing robustness and maintainability. • Short setup time with automated procedures in Trimble Access field software. • Self-check and failsafe procedures for safe operation. • One-button export to Trimble Business Center to create deliverables. • Optimized data accuracy when processed with Trimble Business Center.

### ii. The Trimble UX5 UAS Autonomous Flight And Navigation Modes Enable the UAS to Remain within a Defined Operational Area The UX5 has a semi-autonomous navigation and control system comprised of a Ground Control Station (GCS) and auto-pilot system. All flights are pre-programmed with GPS guidance and do not require human intervention. Flight mission area and routing cannot be changed after launch. Flights are not directed by positive manualcontrol, nor are evasive maneuvers. In the case of unplanned events, the operator inputs pre-programmed evasive maneuvers from the control unit and the control unit executes that maneuver. Pre-programmed operator interventions include diversion to the right; initiation of holding at present position; suspension of mission; fly back to launch point; fly to point and hold; abort mission and land; and emergency power cut off and land (Flight Termination System). iii.

### Although a degradation or loss of the control link, and/or degradation or loss of the source of navigation, is unlikely, it is a situation that is well planned for and therefore, is a benign event. The Trimble UX5 UAS is designed for complete autonomy from launch to landing with a line of sight operator inthe loop monitoring the airframe. Automated safety functions and safety enhancing features of the UX5 include the following:

 Auto-pilot detection of lost GPS or of insufficient satellites initiates an immediate spiral landing.

 Low power on the aircraft triggers escalating alarms at GCS at 35% and 10% levels.

 If the auto-pilot detects a lost-link to the GCS for longer than 30 seconds, landing procedure begins.

 The UX5 is inherently unstable, so auto-pilot fail will result in very rapid exit from flight.

 Aircraft has an on-board failsafe that limits speed in the event of dive to approximately 14 m/s.

 The aircraft, weighing less than 6 lbs., fully loaded, is constructed of EPP foam, or similar material which is intended to absorb impact energy.

 The motor is driven by a pulse width modulated signal, not an analog signal.
iv. Mobile Operation of The Trimble UX5 UAS The Trimble UX5 UAS will not be operated in a mobile capacity. All deployments and operations of the UAS will be from a stationaryposition. The only mobility involving the use of the Trimble UX5 will be in acquisition of the UAS and relocation of the catapult launcher.
b. Flight Operations of the Trimble UX5 UAS are Limited to the Line Of Sight of A Certificated Private Pilot in Command with a Safety Observer GDA will only utilize certificated Private Pilots who possess a valid airman medical certificate to act as a pilot in command of the Trimble UX5 UAS. Additionally, a safety observer will assist all pilots during flight operations. Additionally, both the pilot in command and safety observer must complete the Trimble Operators Courseand be tested to

### ensure knowledge of the functions and operationsof the UAS. The training will be conducted at Frontier Precision, a licensed seller and certifier of the Trimble UX5 UAS, located in Denver, CO.

c. Flights will Be Conducted Pursuant toSpecific Operating Limitations. In seeking this exemption, GDA proposes tocommercially operate the Trimble UX5 UAS for the special purpose of conducting aerialacquisitions within the NAS, pursuant to the specific operating limitations set by the FAA for Trimble Navigation Limited. The limitations have been attached as Appendix D.

Reasons Why an Exemption from the Requirements of Section 61.113(a) Would Not Adversely Affect Safety GDA submits that an equivalent level of safety established by Section 61.113(a) will be maintained because no PIC will be allowed to operate the Trimble UX5 UAS unless that PIC has demonstrated, through the Trimble UX5 UAS training, that the PIC is able to safely operate the UAS in a manner consistent with this exemption, including evasive and emergency maneuvers and maintaining appropriate distances from people, vessels, vehicles and structures. Considering GDA’s proposed area of operations and the operating limitations (Appendix D); unlike a conventional aircraft that carries a pilot, passengers, and cargo, the Trimble UX5 UAS in this case is remotely controlled withno passengers or property of others on board. Commercial certification would be unnecessary and not improve the capabilities of the PIC for the operation of the Trimble UX5 UAS beyond the private pilot certification and Trimble UX5 UAS training. Additionally, the FAA has previously granted relief from Section 61.113(a), specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11158, 11159, 11160, 11161, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 3. Reasons Why An Exemption from the Requirements of Section 91.7(a) Would Not Adversely Affect Safety The level of safety established by Section 91.7(a) will be maintained because prior to every flight, GDA will ensure that the Trimble UX5UAS is in an airworthy condition and safe for flight based upon the Trimble UX5 UAS’s compliance by conducting a pre-flight check before each operation and following its operatingdocuments (i.e., the Trimble UX5 Aerial Imaging Solution User Guide, and the Trimble UX5 Aerial Imaging Solution Maintenance Guide) and as stated in the conditions and limitations. Additionally, the FAA has previously granted relief from Section 91.7(a), specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).
4. Reasons Why An Exemption From The Requirements Of Section 91.119(c) Would Not Adversely Affect Safety
Section 91.119 establishes safe altitudes for operation of civil aircraft. Specifically, 91.119(c) limits aircraft flying over areas other than congested areas to an altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet toany person, vessel, vehicle, or structure. As set forth herein, the UX5 will never operate at higher than 400 feet AGL. It will, however, be operated to avoid congested or populated areas that are depicted in yellow on VFR sectional - 5 - charts. Because aerial survey work must be accomplished at relatively low altitudes and at altitudes less than 500 feet AGL, an exemption from Section 91.119(c) is needed. The equivalent level of safety will be achieved given the size, weight, speed, and material with which the UX5 is built. Also, no flight will be taken without the permission of the land owner or those who control the land. Because of the advance notice to the landowner, all affected individuals will be aware of the survey flights. Compared to aerial survey operations

### conducted with aircraft or rotorcraft weighing far more than 5.5 lbs. and carrying flammable fuel, any risk associated with these operations will be far less than those currently allowed with conventional aircraft operating at or below 500 feetAGL. Indeed, the low-altitude operations of the UAS will maintain separation between these small-UAS operations and the operations of conventional aircraft that must comply with Section 91.119. The FAA has previously granted relief from Section 91.119(c) specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11111, 11112, 11114, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11184, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).
5. Reasons Why an Exemption from the Requirements of Section 91.121 Would Not Adversely Affect Safety The equivalent level of safety established by Section 91.121 will be maintained because the altitude of the Trimble UX5 UAS will be reported to air traffic control (ATC) in feet above ground level (AGL), and GDA will operate the UAS within visual line of sight, at or below 400 feet AGL. Furthermore, the altitude information of the Trimble UX5 UAS will be provided to the PIC via the GPS equipment, and radio communications which transmits altitude information to the control system. Prior to each flight, a zeroaltitude initiation pointis established at ground level. The FAA has previously granted relief from Section 91.121 specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 6. Reasons Why an Exemption from the Requirements of Section 91.151(a) Would Not Adversely Affect Safety This regulation prohibits an individual from beginning “a flight in an airplane under VFR conditions unless (considering wind and forecast weather conditions) there is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed – (1) During the day, to fly after that for at least 30 minutes; or (2) At night, to fly after that for at least 45 minutes.” The UX5 batteries provide approximately 50 minutes of powered flight. Without an exemption from § 14 CFR 91.151, the UAS’s flights would be limited to approximately 20 minutes in length. Given the limitations on its proposed operations and the location of those proposed operations, a longer time frame for flight in daylight VFR conditions is reasonable. GDA believes that an exemption from 14 CFR § 91.151(a) is safe and within the scope of a prior exemption. Operating the small UAS, without 30 minutes of reserve fuel does not engender the type of risks thatSection 91.151(a) was meant to prevent given the size and speed at which the UAS operates. The fact that it carries no pilot, passenger, or cargo also enhances its safety. Additionally, limiting UX5 f lights to 20 minutes would greatly reduce their utility. In the unlikely event that the UX5 should run out of fuel, it would simply land. Given its weight and construction material, the risks are less thancontemplated by the current regulation. GDA believes that an equivalent level of safety can be achieved by maintaining 10 minutes of reserve fuel (battery power), which, allowing 40 minutes of flight time, would be more than adequate to return the UAS to its planned landing zone from anywhere in its operating area. Due to the loss of utility and difficulty of maintaining line of sight of the Trimble UX5 UAS, GDA will not operate the UAS during nighttime operations. The FAA has previously granted relief from Section 91.151, specific to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 8811, 10808, 10673, 11042, 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188, 11189, 11191, 11192, 11193, 11194, 11195, 11204, 11206, 11208, 11209).

### 7. Reasons Why An Exemption From The Requirements Of Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), And 91.417(a) & (b) Would Not Adversely Affect Safety Section 91.405(a) requires that an aircraft operator or owner “shall have that aircraft inspected as prescribed in subpart E of this partand shall between required inspections, except as provided in paragraph (c) of this section, have discrepancies repairedas prescribed in part 43 of this chapter . . . .” Section 91.407 similarly makes reference to requirements in Part 43; Section 91.409(a)(2) requires an annual inspection for the issuance of an air worthiness certificate. Section 91.417(a) requires the owner or operator to keep records showing certain maintenance work that has been accomplished by certificated mechanics, under Part 43, or licensed pilots and records of approval of the aircraft for return to service. Maintenance of the UX5 will be accomplished by the owner/operator pursuant to the manuals, such as Exhibit 3, provided by Trimble. An equivalent level of safety will be achieved because the UAS is small in size,will carry no external payload, will operate only in restricted predetermined areas and is not a complex mechanical devise. As provided in the attached Maintenance Manual and the Safety Checklist, which were reviewed as part of Trimble’s SAC application, the operator of UX5 will ensure that the UAS is in working order prior to initiating flight, perform required maintenance, and keep a log of any maintenance that is performed. Moreover, the operator is the person most familiar withthe aircraft and is best suited to maintain the aircraft in an airworthy condition and toensure an equivalent level of safety. The UX5’s Maintenance Manual provides for replacement of the airframe every 50 hours of flight. This will ensure an equivalent level of safety to the maintenance requirements in Part 91. In addition, between such air frame replacements, should a mechanical issue arise, the aircraft will either return to its launch site or immediately land. The FAA has previously granted relief specific to UAS in circumstances similar, in all material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161, 11166, 11167, 11170, 11171, 11172, 11174, 11176, 11177, 11178, 11185, 11188,11189, 11191, 11192, 11193, 11194 ,11195, 11204, 11206, 11208, 11209).

# TRIMBLE UX5 LAUNCHER

1 

## Before you head out to the fi eld Make sure the launcher bag contains the following items:
• Safety pin.
• Launch dock with lock pin.
• V-support.
• Crank.
• Launch slide with elasti cs.
• Trimble UX5 Launcher Quick Start Guide(this document) 

### QUICK START GUIDE2. Secure each secti on of the launch slide by lift ing the appropriate handle and hooking it into the next secti on of the launch slide. Close the handles.

2 3. Unfold and secure the V-support with the lock pin. To att ach the V-support to the launch slide, make sure the knob is pointi ng to the left and then insert the V-support pins in the reserved holes, situated approximately 2/3 of the length of the launch slide. Turn the knob to the right to ti ghten. 

# Assembling the launcher You are prompted to prepare the launcher during the fl ight checklist. 1. Unfold the launch slide. 

### CCAUTION – Take care when unfolding the launch slide as there are sharp edges that can cause fi nger cuts.4. Pull the ends of the launcher cord out of the launch slide so that the cord lies on top of the launch slide. Note – If the launcher cord is blocked while the elasti cs are not ti ghtened, pull the release handles upward to unblock them. 

### C CAUTION – Never push the release handles when there is tension on the launcher cord. You will damage the elasti cs. If there is tension on the launcher cord, see step 1 of “Disassembling the launcher.” 5. Positi on the launch dock on the end of the launch slide with the tabs on the launch dock pointi ng toward the directi on of launch.

6. Slide the launch dock over the ends of the launcher cord. 7. To att ach the ends of the launcher cord to the launch dock, remove the lock pin from the launch dock and then slide the lock pin through the holes in the launch dock, att aching the ends of the launcher cord as you do so. Secure the lock pin.

38. Slide the launch dock over the hook at the beginning of the launch slide. Make sure the launch dock clicks into positi on and the trigger is not blocked. 9. Insert the safety pin into the launch dock.



### C WARNING – Always keep the safety pin inserted in the launch dock. Remove the safety pin only just before launch. Early removal of the safety pin can result in accidental release of the launcher, causing serious personal injury and damage to the UX5 or launcher. 

### C CAUTION – Never launch without the UX5 sitti ng on the dock as it will damage the launch dock. The design of the launcher takes into account the weight of the UX5 sitti ng on the launch dock. 10.Positi on the launcher at the planned takeoff locati on, with the launch directi on pointi ng into the planned takeoff directi on. 11.Make sure the takeoff locati on is free of obstacles: • From 0 m to 50 m (164 ft ): No obstacles within 30° to the left and right. • From 50 m to 280 m (164 ft to 919 ft ): No obstacles above the 15° safety angle and within 25 m (82 ft ) lto the left and right of the launch directi on.

4

# Placing the UX5 onto the launcher 1. Positi on the UX5 at the front of the launch dock and use your fi nger ti ps to guide the launcher slats on the underside of the UX5 onto the lips of the launch dock.

5 2. Use the arti fi cial horizon indicator in the Aerial Imaging soft ware to check the pitch and roll of the UX5 on the launch dock: The pitch angle should be between 20° and 30° and the roll angle should be between -5° and 5°. The horizon should be positi oned parallel to the UX5 on the arti fi cial horizon indicator. If you need to adjust the horizon, repositi on the launcher. 

### C WARNING – Take care to ensure the UX5 is correctly positi oned on the launch dock. An incorrect positi on can result in launch failure, causing serious personal injury and damage to the rover or launcher.

# Removing the safety pin Positi on yourself behind the launcher, reach carefully under the UX5 and then pull out the safety pin. 

### C WARNING – Always take care to avoid contact with the propeller blades. If the UX5 receives a sudden shock while armed, the motor can unexpectedly start causing the propeller blades to move. Contact with moving propeller blades can result in serious personal injury. 

# Tightening the launcher cord elasti cs 1. Insert the crank onto the nut located toward the front end of the launch slide. 2. Stretch the launcher cord using the crank. In normal circumstances, the node between the cord and elasti c should be in the middle of the hole numbered “4” on the launcher. 

### C CAUTION – The launcher cord stretches with every launch. When you can easily reach the last hole when ti ghtening the cord, replace the launcher cord to prevent unsuccessful launches or damage to equipment. For more informati on, click Maintenancein the Homescreen 3. Remove the crank.

6

# Launching the UX5 Once you have armed the system, the software prompts you to launch the aircraft. 1. Just before launch, perform the following safety checks:

• Make sure there are no aerial objects inside the zone of operation.

• Make sure you have a clear line of sight to the UX5.

• Make sure there are no obstacles or people near the front of the launcher. 

### C WARNING – Make sure you complete each of the safety checks listed at this step. Failure to do so could result in serious personal injury and damage to the UX5 or launcher. 2. When you have made sure that everything is clear in front of, above, and behind the launcher, stand behind the launcher and press the launch handle to launch the UX5. 

### C CAUTION – Never launch without the UX5 sitting on the dock as it will damage the launch dock. The design of the launcher takes into account the weight of the UX5 sitting on the launch dock. 3. If an obstacle such as a person or animal suddenly appears in the obstacle clearance zone during takeoff , tap the FTS icon in the Aerial Imaging software. The UX5 immediately powers down and returns to the ground. For more information, refer to the Trimble UX5 Aerial Imaging Solution User Guide

. After launch, the UX5 flies to the first waypoint, which is highlighted in the Dashboard tab. If the UX5 is not yet at the flight height when it reaches this point, it climbs in circles of 100 m radius until it reaches the desired height. 4. After launch, release the tension on the launcher cord. Leaving tension on the launcher cord for extended periods can damage the elastics. See “Disassembling the launcher.”

# Disassembling the launcher 1. Release the tension on the launcher cord, if you have not already. To release the tension, release the force with the crank very gently while pulling the release handles in the front of the launcher upward. This is safestdone with two people, with one person carefully winding the crank counterclockwise to counteract the force on the elastics.

2. Remove the lock pin on the launch dock and detach the launcher cord. 3. Using the crank, tighten the launcher cord so that most of the cord is in the launch slide but the end remains out. Remove the crank. 4. Slide the launch dock off the front of the launch slide. 5. To detach the V-support, turn the knob upward and then slide the pins out of the holes in the launch slide. Remove the lock pin on the V-support to fold the legs and then reinsert the lock pin. 

### C CAUTION – Take care when folding the V-support legs not to jam or cut fingers. 6. Open the handle fixes on the launch slide and fold the launch slide. 7. Return all of the launcher items to the launcher bag.
