Re: Exemption Request Under Section 333 of the FAA Reform Act and Part 11 of the Federal Aviation Regulations

Dear Sir or Madam:

Pursuant to Section 333 of the FAA Modernization and Reform Act of 2012 (the “Reform Act”) and 14 C.F.R. Part 11, Terra Imaging LLC (“Terra Imaging”) , operators of Unmanned Aircraft System (“UAS”), seeks an exemption from the Federal Aviation Regulations (“FARs”) listed below.

The requested exemption would permit commercial operation of Trimble’s UX5 and DJI

S1000 , which perform precision aerial surveys and closed set cinematography that consist of digital imagery taken by onboard cameras

. Both UAS will b e operated by Terra Imaging and will be registered in accordance with 49 U.S.C. 44103, Registration of Aircraft , as well as 14 C.F.R Part 47, Aircraft Registration , and marked in accordance with 14 C.F.R. Part 45, Identification and Registration Marking

.

Moreover, the Trimble UX5 and DJI S1000 camera systems collect imagery and mapping

data that are used to produce precision 3D topographic maps and 3D models. App lications for general UAS operations include agriculture, mining, and professi onal surveying. Use of the UAS for aerial mapping reduces the need to operate conventional

aircraft thereby saving thousands of dollars on operations and fuel costs, producin g jobs locally and nationwide. Both t he Trimble UX5 and DJI S1000 are battery powered emitting zer o fossil fuels or emissions providing a gr eener airborne mapping solution. Terra Imaging is actively involved with various wildlife conservation and marine research agencies, the benefit of a UAS system to these entities would provide affordable

data for s cientific and education purposes, the benefits of current, high resolution mapping data to the public sector are enormous.

The requested exemption would authorize commercial operations of UAS under

controlled conditions by UAS professionals, formally tra ined as Trimble Certified UAS Pilots and Operators ; specifically operating all UAS operations within FAA pre approved airspace disclosed in advance with FAA Flight Planning.

Traditional precision aerial surveys, airborne photogrammtry and cinematography

include use of the follo wing airborne camera and sensor systems:

Terra Imaging acknowledges t he operational use of the Trimble UX5 and DJI S1000 are

within FAA adherence of proposed regulations based on:

• UAS’s size, weight, sp eed, and operational capability

• Operation of the UAS NOT in close proximity to a irports and populated

areas;

• Operation of the UAS within visual line of sight of the operator.

Under grant of the exemption, T erra Imaging agrees to operate the Trimble UX5 and DJI

S1000 with the following restrictions:

• All operations to occur in Class G airspace.

• All UAS will weigh less than 50lbs.

• All airborne op erations occur during daylight hours.

• All UAS pilots, will be professionally trained and certified UAS pilots, formally trained as a Certified Trimble UAS Pilot and Operator.

• Operations to avoid congested or populated areas, which are depicted in yellow on VFR charts.

• Operations to be conducted over private or controlled

- access property.

• Permission from land owner/controller required before commencing any flight.

• Operations to occur during Visual Flight Rules Meteorological Conditions (VMC).

• Aircraft to remain within Visual Line of Sight (VLOS). o

• VLOS guaranteed with a cylinder of operation around operator of .5 nautical miles (NM).

• Cylinder walls may be expanded by observer with ability to control

aircraft.

• Above Ground Level (AGL) altitude to be r estricted to 5 00 feet.

• All operations conducted in vicinity of airport to remain more than 2.5 NM from centerline azimuth of runway centerline measured from runway

thresholds.• Operator will file a NOTAM for each flight.

• All required permissions and perm its will be obtained from territorial, state, county or city jurisdictions, including local law enforcement, fire, or other appropriate governmental agencies.

Terra Imaging based on the recommendations of Trimble and DJI, agrees to the Operator Requirements. I n detail, the Trimble UX5 and DJI S1000 have 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 mi ssion area and routing cannot be changed after launch. Flights are not directed by positive manual control, nor are evasive maneuvers. In the case of unplanned events, the operator inputs pre

- programmed evasive maneuvers from

the control unit and the contr ol 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 p ower cut off and land (Flight Termination System).

Additional automated safety functions and safet y enhancing features of the UAS 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 UAS is inherently unstable, so auto

- pilot fail will result in very rapid exit from flight.

• Ai rcraft has an on

- board failsafe.

I n summary, Terra Imaging seeks an exemption from the FARs set forth bellow to allow commercial operations of a small unmanned vehicle con ducting precision aerial surveys and closed set cinem atography . Approval of the exemption allowing commercial operations of the Trimble UX5 and DJI S1000 for precision survey work will enhan ce safety by reducing risk. Both the Trimble UX5 and DJI S1000 are carried to the survey location, not flown there. The Trimb le UX5 and DJI S1000 will carry no passengers or crew and, therefore, will not expose any individuals to the risks associated with manned aircraft flights. Additionally, no national security issue is raised by the grant of the requested exemptions. Given t he size, load carrying capacity, speed at which it operates, and the fact that it carries no explosives or other dangerous materials, the Trimble UX5

and DJI S1000 poses no threat to national security.Following are the Exemp tions Requested:

14 C.F.R. Part 21, Subpart H: Airworthiness Certificates 14 CFR § 91.203(a)(1)

Section 91.203(a)(1) requires all civil aircraft to have a certificate of airworthiness. Part 21, Subpart H, entitled Airworthiness Certificates, establishes the procedural requirement s for the issuance of airworthiness certificates as required by FAR § 91.203(a)(1). Given the size of the aircraft (5.5lbs.) and the limited operating area associated with its utilization, it is unnecessary to go through the certificate of airworthiness pr ocess under Part 21 Subpart H to achieve or exceed current safety levels. Such an exemption meets the requirements of an equivalent level of safety under Part 11

and Section 333 of the Reform Act. The Federal Aviation Act and Section 333 of the

Reform Act both authorize the FAA to exempt aircraft from the requirement for an airworthiness certificate, upon consideration of the size, weight, speed, operational capability, and proximity to airports and populated areas of the UAS involved.

In this case, an a nalysis of these criteria demonstrates that the Trimble UX5 and DJI

S1000 operated without an airworthiness certificate, under the conditions proposed herein, will be at least as safe, or safer, than a conventional aircraft (fixed wing or rotorcraft) with an airworthiness certificate. The Trimble UX5 and DJI S1000 weighs less

than 25 lbs. fully loaded. It will not carry a pilot or passenger, will not carry flammable fuel, and will operate exclusively within an area pre

- di sclosed and in compliance with

condit ions set forth herein. Operations under this exemption will be tightly controlled and monitored by both the operator, pursuant to the conditions set forth above, and by local public safety requirements. The FAA will have advance notice of all operations th rough the filing of NOTAMs. Receipt of the prior permission of the land owner, the size of the aircraft, the lack of flammable fuel, and the fact that the aircraft is carried to the location and not flown there all establish the equivalent level of safety. The Trimble UX5 and DJI

S1000 construction with absorbent material provides at least an equivalent level of safety to that of such operations being conducted with conventional aircraft that would be

orders

- of

- magnitude larger and would be carrying passengers, cargo, and flamma ble fuel.

14 C.F.R. § 45.23 (b). Marking of the Aircraft

The regulation requires: When marks include only the Roman capital letter "N" and the registration number is displayed on limited, restricted or light

- sport category aircraft or experimental or pr ovisionally certificated aircraft, the operator must also display on that aircraft near each entrance to the cabin, cockpit, or pilot station, in letters not less than 2 inches nor more than 6 inches high, the words "limited," "restricted," "light

- sport," "experimental," or "provisional," as applicable.

The Trimble UX5 and DJI S1000 have no e ntrance to the cabin, cockpit or pilot station on which the word “Experimental” can be placed. Given the size of the UAS, two

- inch lettering will be impossible. The wor d “Experimental” will be placed on the fuselage in compliance with §45.29 (f). The equivalent level of safety, which is fully sufficient forthe small UAS size, will be provided by having the UAS marked on its fuselage as required by §45.29 (f) where the p ilot, observer and others working with the UAS will

see the identification of the UAS as “Experimental.”

14 C.F.R. § 61.113 (a) and (b): Private Pilot Privileges and Limitations: Pilot in

Command. Pursuant to 14 CFR 61.113 (a) & (b), no person who holds a private pilot certificate may act as a pilot in command of an aircraft that is carrying passengers or property for compensation or hire.

Section 61.113(a) & (b) limit private pilots to non

- commercial operations. Unlike a

conventional aircraft that carri es a pilot, passengers, and cargo, the Trimble UX5 and DJI

S1000 in this case is remotely controlled with no passengers or property of others on board. Section 61.133(a) requires an individual with a commercial pilot’s license to be pilot in command of an air craft for compensat ion or hire. The Trimble UX5 and DJI

S1000 has a high degree of pre

- programmed control and various built

- in technical capabilities that strictly limit the potential for operation outside of the operating conditions set forth in the exemption application.

Both UAS have a semi

- autonomous navigation and control system comprised of a

Ground Control Station (GCS) and auto

- pilot system. All flights are pre

- programmed with precision GPS guidance and do not require human intervention. Flight mission area

and routin g cannot be changed after launch. Flights are not directed by positive manual control, 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

tha t 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 lan d (Flight Termination System).

Additional automated safety functions and safety enhancing features of the Trimble UX5

and DJI S1000 include the following:

• Auto

- pilot detection of lost GPS or of insufficient satellites initiates an immediate spiral lan ding.

• 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 Trimble UX5 and DJI S1000 are 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 in tended to absorb impact energy.

• The motor is driven by a pulse width modulated signal, not an analog signal.

Given these safety features, Terra Imaging proposes that operators of the Trimble UX5

and DJI S1000 should not be required t o hold a commercial or private pilot certification. Instead, operators should be required to:

• H ave succ essfully completed, at a minimum Certified Trimble UAS Pilot and Operations training.

• H ave completed the manufacturer’s training pr ogram for operation of the UAS.

The manufacturer’s training program will have been satisfactorily reviewed through the SAC process. Given these conditions and restrictions, an equivalent level of safety will be provided by allowing operation of the Trimble UX5 and DJI S1000 without a private pilot’s certificate or a commercial pilot’s certificate, under the conditions set forth herein. The risks associated with the operation of the Trimble UX5 and DJI S1000 (given its size, speed, operational capabilities, and lack of combus tible fuel) are so diminished from the level of risk associated with private pilot operations or commercial operations contemplated by Part 61 with conventional aircraft (fixed wing or rotorcraft), that allowing operations of the UAS as set forth above mee ts or exceeds the present level of safety provided under 14 C.F.R. § 61.113(a) & (b) and does not rise to the level of requiring a commercial pilot to operate the aircraft under § 61.133(a).

14 C.F.R. §91.7(a): Civil Aircraft Airworthiness. The regulatio n requires that no person may operate a civil aircraft unless it is in airworthy

condition. As there will be no airworthiness certifica te issued for the Trimble UX5 and

DJI S1000 , should this exemption be granted, no FAA regulatory standard will exist for determining airworthiness. Given the size of the aircraft for maintenance and use of safety check lists prior to each flight an equivalent level of safety will be provided.

14 C.F.R. § 91.9 (b) (2): Civil Aircraft Flight Manual in the Aircraft.

Section 9 1.9 (b) (2) provides: No person may operate a U.S.

- registered civil aircraft ... (2) For which an Airplane or Rotorcraft Flight Manual is not required by §21.5 of this chapter, unless there is available in the aircraft a current approved airplane or

Rotorc raft Flight Manual, approved manual material, markings, and placards, or any combination thereof.

The UAS, given its size and configuration has no ability or place to carry such a flight manual on the aircraft, not only because there is no pilot on board , but because there is no room or capacity to carry such an item on the aircraft. The equivalent level of safety will be maintained by keeping the flight manual at the ground control point where the pilot flying the UAS will have immediate access to it.14 C.F.R. § 91.109(a) & 91.319(a)(1): Flight Instruction

These regulations provide that no person may operate a civil aircraft (except a manned free balloon) that is being used for flight instruction unless that aircraft has fully functioning dual contro ls. The UX5 is a remotely piloted aircraft and by design, does not have fully functional dual controls. Flight control is accomplished through the use of a control box that communicates with the aircraft via radio communications. The flight plan is pre

- pro grammed into the auto pilot before flight and only in unusual circumstances will the pilot input control functions to alter the pre

- programmed flight. If instruction is accomplished through a training program, as set forth in Exhibit 2, an equivalent level of safety will be assured. The FAA has approved exemptions for flight training without fully functional dual controls for a number of aircraft and for flight instruction in experimental aircraft. See Exemption Nos. 5778K & 9862A. The equivalent level of safety will be achieved by the manufacturer provi ding the training as outlined, and for the use of experienced and qualified pilots familiar with the Trimble

UX5 and DJI S1000

.

14 CFR § 91.119: Minimum Safe Altitudes Section 91.119 establishes safe altitudes for operation o f civil aircraft. Specifically, 91.119(c) limits aircraft flying over areas other than con gested areas to an altitude of 4 00 feet above the surface, except over open water or sparsely populated areas. In those cases,

the aircraft m ay not be operated closer than 4 00 feet to any person, vessel, vehicle, or structure. As set forth herein, the UX5 wil l never operate at higher than 4 00 feet AGL. It will, however, be operated to avoid congested or populated areas that are depi cted in yellow on VFR sectional chart s. Because precision aerial survey and c losed set

c inematography must be accomplished at relatively low altitu des and at altitudes less than

4 00 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

conv entional aircraft operating at or below 4 00 feet AGL. Indeed, the low

- altit ude 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.

14 C.F.R. § 91.151(a): Fuel Requirements for Flight in VFR Conditions

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 t o 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 tha t for

at least 45 minutes.” Both the Trimble UX5 and DJI S1000 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 limitat ions on its proposed operation and the location of those proposed operations, alonger time frame for flight in da ylight VFR conditions is reasonable. Operating the small UAS, without 30 minutes of reserve fuel does not engender the type of risks that Section 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 Trimble UX5 and DJI S1000 flig hts to 20 minutes would greatly reduce their utility. In the unlikely event that the Trimble UX5 and SJI S1000 should run out of fuel, it would simply land. Given its weight and construction ma terial, the risks are less than contemplated by the current regulation.

Ter ra Imaging believes that an equivalent level of safety can be achieved by maintaining 10 minutes of reserve fuel, which, allowing 40 minutes of flight time, would be more

than ade quate to return the UAS to its planned landing zone from anywhere in its operating area.

14 C.F.R. § 91.203 (a) & (b): Carrying Civil Aircraft Certification and Registration This regulation provides as follows: (a) . . . no person may operate a civil aircraft unless it has . . . an appropriate

and current airworthiness certificate. (b) No person may operate a civil aircraft unless the airworthiness certificate required by paragraph (a) of this section or a special flight authorization issued

under §91.715 is displayed at the cabin or cockpit entrance so that it is legible to

passengers or crew. The Trimble UX5 and DJI S1000 ful ly loaded weighs no more than 50 lbs. As such, there is no ability or place to carry certification and registration documen ts or to display them on the UAS. In addition, there is no pilot on board the aircraft. An equivalent level of safety will be achieved by keeping these documents at the ground control point where the pilot flying the UAS will have immediate access to them. The FAA has issued numerous exemptions to this regulation. A representative sample of other exceptions includes Exemption Nos. 9565, 9665, 9789, 9789A, 9797, 9797A, 9816A, and 10700.

14 C.F.R. § 91.405(a); 407(a)(1); 409(a)(2); 417(a): Maintenance Inspe ctions

Section 91.405(a) requires that an aircraft operator or owner “shall have that aircraft inspected as prescribed in subpart E of this part and shall between required inspections, except as provided in paragraph (c) of this section, have discrepanci es repaired as 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) requi res 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 Trimble U X5 and DJI S1000 will be acc omplished by Terra Imaging pursuant to the manuals 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 predetermin ed areas and is not a complex mechanical devise. Terra Imaging will ensure that the UAS is in working order prior to initiating flight, performrequired maintenance, and keep a log of any maintenance that is performed. Moreover, the operator is the person most familiar with the aircraft and is best suited to maintain the aircraft in an airworthy condition and to ensure an equivalent level of safety.

The Trimble UX5 and DJI S1000 ’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.

Sincerely,

Karl Engstrom
