Re: Exemption Request Pursuant to Section 333 of the FAA Modernization and Reform Act 

of2012, 49 U.S.C. § 4470l(f), and Part 11 of the Federal Aviation Regulations 

Dear Sir or Madam: 

All American Energy Services, LLC. ("AA Energy"), pursuant to Section 333 ofthe FAA 

Modernization and Reform Act of2012 (the "Reform Act") ("Section 333"), Subsection (t) of 49 U.S.C. § 44701, and 14 C.F.R. Part 11, is requesting an exemption from the Federal Aviation Regulations 

("F ARs") listed below and discussed in Appendix A to allow AA Energy to conduct commercial 

operations with Tuffwing UAV mapper Unmanned Aircraft System ("UAS") (the "Tuffwing") to 

provide surveying and energy development services, which are primarily located in remote unpopulated 

areas with minimal air traffic. These services include obtaining still photographs, real-time video, and 

other data taken by onboard sensors to monitor operations, environmental conditions, and forestland 

security. Performing these services with a UAS is in the public interest for several reasons, which are 

detailed further herein and include: (I) minimizing safety risks inherent in manned operations, both in the air and on the ground; (2) inspecting locations where humans are not able to go; (3) enhancing 

capabilities to utilize the UAS to assist first responders on safety or environmental incidents; (4) 

improving access control/security to sites; and (5) monitoring environmental conditions. 

The battery-powered Tuffwing weighs 54 ounces and has a flight time of 40-45 minutes depending on operating conditions. It employs a self-stabilizing aircraft configuration with stability augmentation avionics that provides ease-of-control and steady video imagery. Its high- performance design leverages advanced composite materials, innovative electronics, and cutting-edge sensor technology to increase 

mission capabilities and make Tuffwing a reliable and accurate solution to meet a variety of industry needs. 

Operations under the exemption will be conducted under the limitations and conditions set forth in 

Appendix Band as may be modified by the FAA as required by Section 333.2. Use of the Tuffwing in 

AA Energy's operations as proposed herein, would provide significant public safety benefits over 

existing inspection and survey operations, while operating safely within the National Airspace System ("NAS"). 

Use of UAS offers numerous safety benefits for operations on the ground. First, the use of UAS would 

alleviate the need for personnel to perform difficult and dangerous manual inspections of remote, 

Page 1 
more efficient operations. For inspections now conducted by manned aircraft, use of the UAS for these 

services will reduce the need to operate manned aircraft in a difficult environment and reduce the 

environmental impact of conventional aircraft operations. In addition, the small, lightweight, and easily controllable operating characteristics of the Tuffwing provide for safe operations over the remote or uninhabited locations of gas development and timberland. This feature would also be beneficial in 

surveying from above in detail features of facilities that it would be too dangerous to fly manned aircraft close to. Our clients also maintain strict control over access to their facilities, require all personnel to 

wear personal protective gear, including hard hats and safety glasses, and attend site-specific safety hazard briefings to be onsite, so these proposed operations would not endanger workers onsite. 

Although the Tuffwing can be operated by one person, AA Energy's flight operations will always involve at least two people as required by the FAA: a vehicle operator ("VO") and a mission operator ("MO"). The VO is responsible for flying the UAS, monitoring its status and flight dynamics, while keeping the flight within the manufacturer's specified operational limits to ensure safe operation of the vehicle. MOs will be responsible for monitoring the airspace for other aircraft and hazards and advising the VO before and during flight of all such observed risks. In addition to completing AA Energy's training, the VO will hold at least a state-issued motor vehicle driver's license. 

While AA Energy has modeled its request off of Part 333 Exemption grants as of the date of its application, AA Energy requests that the FAA treat AA Energy's application as requesting the most lenient relief granted to similar applicants at the time of adjudication. Additionally, should the FAA modify any of its UAS operating conditions through exemptions or otherwise after adjudicating M Energy's application, M Energy requests blanket approval to operate it's UAS in accordance with the 

more lenient operating conditions. AA Energy reserves the right to supplement or amend its application.

Exemptions Requested: 

All American Energy Services, LLC requests exemptions from the following regulations: 14 C.F.R. Part 21 ; 14 C.F.R. 61.113(a) and (b); 14 C.F.R. 91.7(a); 14 C.F.R. 91.119(c); 14 C.F.R. 91.121; 14 C.F.R.

the requirement for an airworthiness certificate upon consideration of the size, weight, speed, 

operational capability and proximity to airports and populated areas of the particular UAS. In all cases, 

an analysis of these criteria demonstrates that the UAS operated without an airworthiness certificate, in 

the restricted environment and under the conditions proposed herein will be at least as safe, or safer, 

than a conventional aircraft (fixed wing or rotorcraft) operating with an airworthiness certificate without 

the restrictions and conditions proposed. 

The Tuffwing is a more recently developed system. It does, however, utilize industry- standard sensors 

and controls, which provide numerous fail safes. The Tuffwing is equipped with automated features for 

safe takeoff, flight, and landings in varying conditions. The shorter flight times and very high 

maneuverability will dictate that this system will be used in close proximity to the operator and at lower 

altitudes, which will increase the safety of the system. Tuffwing Operator's Manual will be provided. 

Pre- and post-flight inspections and systems checks will precede and follow each flight following a 

prescribed protocol. Test flights are conducted following any upgrades to system software, firmware, or 

hardware to ensure safety of operations. 

Unlike other civil aircraft, operations under this exemption will be tightly controlled and monitored by 

AA Energy pursuant to the Safety Checklist's requirements, and under the requirements and in 

compliance with local public safety requirements, to provide security for the area of operation as is now 

done with conventional aerial mapping and surveying. These safety enhancements, which already apply 

to civil aircraft operated in connection with mapping and surveying operations, provide a greater degree 

of safety to the public and property owners than conventional operations conducted with airworthiness 

certificates issued under 14 C.F .R. Part 21, Subpart H. Application of these same criteria demonstrates 

that there is no credible threat to national security posed by the UAS, due to its size, speed of operations, 

location of operation, lack of explosive materials or flammable liquid fuels and inability to carry a 

substantial external load. 

Operating Conditions: 

AA Energy requests an exemption subject to the conditions listed in Appendix B, which are 

substantially similar to the operating conditions required for the FAA's previous grants of exemptions 

under Section 333. In accordance with the conditions approved in previous exemption grants, AA 

Energy is requesting authority to operate the Tuffwing within visual line of sight and below 200 feet 

AGL. The area of operations would include those lands owned or leased by AA Energy's clients in the 

ranching, natural gas, oil, utilities, wildlife, or timberland management industries across the United 

States. Given that the operating sites are often not flat, AA Energy will use the elevation of the highest 

predominant terrain within 1 mile of the launch point and within the visual line of sight as a ground 

reference point to establish the 200 feet ceiling. In other words, AA Energy will not operate the 

Page3

gy

ted due to the terrain. In 

addition to the requirement that pilots must fly at least 500 feet AGL, the FAA recommends that pilots 

operating under Visual Flight Rules ("VFR") fly over ridges with at least 1,000 feet clearance. Pilots 

flying under instrument flight rules ("IFR") over mountainous areas must fly at "an altitude of 2,000 feet 

above the highest obstacle within a horizontal distance of 4 nautical miles from the course to be flown. 1 

Given the locations of our projects and FAA minimum flight altitudes, the Tuffwing will be able to 

operate below altitudes in use by manned aircraft. 

Third, the VO will operate the Tuffwing from higher elevations in regard to project area when possible, 

allowing the MO to maintain full visibility of the airspace over the project to avoid conflict with any 

manned aircraft. AA Energy will use a MO who will stay in radio contact with the VO if the terrain 

warrants it. 

Fourth, AA Energy's operational procedures will require VOs to deconflict by suspending all UAS 

operations when a manned aircraft operates within airspace infringement boundaries, greatly reducing 

the risk to any manned aircraft. The VO will be able to immediately land the UAS when the VO or MO 

spot another manned aircraft within the planned area of operations or safety personnel direct 

cessation ofUAS operations. 

Fifth, AA Energy maintains contact with any personnel onsite, requiring all personnel to wear personal 

protective gear, including hard hats and safety glasses, and mandates site specific safety training as 

required by clients. Non-participant AA Energy employees will carry radios and be alerted before UAS 

operations begin. These safeguards, along with the UAS's light weight, provide an equivalent level of 

safety for non-participants to be closer than 500 feet. 

Sixth, the Tuffwing is equipped with visible strobe lights that will alert any manned aircraft in the area 

to its position. 

Seventh, the Turffwing flight software, Pixhawk Mission Planner manufactured by 30 Robotics, 

provides many built-in functional and safety features to assist the VO in safe and reliable operation. 

Both systems can operate autonomously in "Navigation" mode. In Navigation mode, the VO selects 

waypoints, rally points, and a landing area before launching. The UAS then uses GPS navigation to 

follow the pre-selected flight path. The UAS also can be flown in a semi-autonomous mode in which the 

UAS flight software maintains a preset altitude and airspeed and the VO controls heading. Additionally, 

1 FAA Aviation Safety Program, Tips on Mountain Flying, available at 

htms:l/www.faa.fWvlregulations poli.£jeslhandbooks manuals/aviation/media/tips on mountain flyjog.pdf. Pilots operating under VFR also must operate at an altitude that would allow them to make an "emergency landing without undue hazard to 

persons or property on the surface." 14 C.F.R. § 91.119(a). 6 FAR 91.177(a)(2)(i).

adio contact 

with safety personnel. AA Energy requests authorization to operate the Tuffwing less than 500 feet 

from nonparticipating employees without barriers or structures to protect them, provided they wear 

customary safety gear (e.g. hard hats). An equivalent level of safety is provided because the UAS's 

weight, materials, and reliability, along with the required operator training and operating environment, 

prevent these systems from posing a serious risk to clients/employees wearing personal protective gear. 

Operator Requirements: 

Sections 61.113(a) and (b) limit private pilots to non-commercial operations. Because the UAS will not 

carry a pilot or passengers, the proposed operations can achieve the equivalent level of safety of current 

operations by requiring the PICs operating the UAS to have a private pilot's license rather than a 

commercial pilot's license to operate the UAS. Unlike a conventional aircraft that carries the pilot and 

passengers, the UAS is remotely-controlled with no living thing on board. The area of operation is 

controlled and restricted, and all flights are planned and coordinated in advance as set forth in the Safety 

Checklist. The level of safety provided by the requirements included in the Safety Checklist exceeds 

that provided by a single individual holding a commercial pilot's certificate operating a conventional 

aircraft. The risks associated with the operation ofthe UAS are so diminished from the level of risk 

associated with commercial operations contemplated by Part 61 when drafted, that allowing operations 

of the UAS as requested with a private pilot as the PIC exceeds the present level of safety achieved by 

14 C.F.R. §61.113(a) and (b). 

Public Interest: 

AA Energy respectfully submits that its use of the UAS in lieu of manned operations, which are 

currently conducted with conventional fixed wing and rotary aircraft, offers a net safety benefit and will 

achieve an enhanced level of safety, as mandated under Section 333(c) of the Reform Act. Approval of 

this application also will benefit the public interest by allowing better, safer, and more cost efficient 

information gathering for the ecosystem services and energy development industries. Conventional 

aerial survey and inspection operations using manned aircraft involve very heavy aerial vehicles that 

must transit to the operational location and carry significant quantities of combustible fuels and a multiperson crew in piloting and observation roles. These operations become even more difficult in the 

energy and forestry industries due to the terrain. By contrast, the Tuffwing weighs 3.375 lbs., including 

its payload, uses a battery for power, is carried to and from the area of activity, removes the need for 

airborne pilots and observers, and poses less risk to people and infrastructure on the ground, as well as 

other aircraft. Additionally, no national security issue is raised by the grant of the requested exemptions 

due to the UAS's small size and load-carrying capacity, as well as its operational limitations and absence 

of flammable fuel. On the other hand, the use of these systems is likely to enhance national security 

through better and more accurate monitoring of critical national infrastructure. The grant of the

The proposed operations will take place only in largely unpopulated, remote areas that are owned or 

leased, and access controlled by AA Energy's clients. Access to these areas is generally restricted to 

employees and authorized personnel only. No privacy issues are raised by this application. 

Federal Register Summary: 

Pursuant to 14 C.F.R. § 11.81(t), the following summary is provided for publication in the Federal 

Register, should the FAA determine that publication is needed:

om the following regulations as well as any additional regulations 

that may technically apply to the operation of the Tuffwing UAS: 

14 C.F.R. Part 21, Subpart H: Airworthiness Certificates 

Part 21 , Subpart H, entitled Airworthiness Certificates, establishes the procedural requirements for the 

issuance of airworthiness certificates as required by§ 91.203(a)(1 ). Given the size and weight ofthe 

aircraft, the operating conditions, design safety features, and the proposed conditions and limitations, it 

is unnecessary to go through the certificate of airworthiness process 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. Section 333 and 49 U.S.C. § 44701(t) 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 analysis of these criteria demonstrates that the UAS 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 Tuffwing weighs 3.375 

pounds fully loaded. It will not carry a pilot, passenger or flammable fuel. These UASs operate 

exclusively within a controlled area pre- disclosed and in compliance with conditions set forth herein. 

Unlike other civil aircraft, operations under this exemption will be tightly controlled and monitored 

by the VO and observer(s), pursuant to the conditions set forth in Appendix B, the Operator's Manual, 

and local public safety requirements. 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 UAS 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 flammable fuel. 

14 C.F.R. §§ 61.113(a) & (b): Commercial Pilot Privileges 

Sections 61.113(a) & (b) limit private pilots to non-commercial operations. Unlike a conventional 

aircraft that carries a pilot, passengers, and cargo, the Tuffwing is remotely controlled with no 

passengers or property of others on board. The area of operation is controlled and restricted, and all 

flights are planned and coordinated in advance as set forth in the Operator's Manual. In conjunction with 

the required training of the V 0 and observers, the level of safety provided by the requirements included 

in the Operator's Manual exceeds that provided by a single individual holding a commercial pilot 

certificate operating a conventional aircraft. The proposed operations will achieve at least an 

equivalent level of safety. 

14 C.F.R. § 91.7(a): Minimum Safe Altitudes 

Page 7 
Section 91.119 establishes safe altitudes for operation of civil aircraft. Specifically, Section 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 to any person, vessel, vehicle, or structure. Because some of the aerial inspection and survey work must be accomplished at altitudes less than 500 feet AGL and nonparticipating employees will be working within 500 feet ofthe UAS, an exemption from Section 91.119(c) is needed. 

The equivalent level of safety will be achieved because AA Energy's employees and the client's onsite 

employees are required to wear personal protective gear and because the UAS, given its size, weight, speed, and materials, does not pose a serious risk. Also, every flight will be conducted over land owned 

or controlled by AA Energy's clients. Compared to aerial inspection operations conducted with aircraft 

or rotorcraft weighing far more than 3.375 pounds (for the Tuffwing) 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 feet AGL. 

14 C.F .R. § 121: Altimeter Setting 

Section 121 requires each person operating an aircraft to maintain cruising altitude by reference to an 

altimeter that is set "to the elevation of the departure airport or an appropriate altimeter setting available 

before departure." As the UAS may not have a barometric altimeter, but instead a GPS altitude read out, 

an exemption is required. An equivalent level of safety will be achieved by the operator, pursuant to the Operator's Manual, confirming the altitude of the launch site shown on the GPS altitude indicator before 

flight. 

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 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 Tuffwing batteries 

provide approximately 40-45 minutes of powered flight. Without an exemption from 14 C.F.R. § 

91.151, the Tuffwing flights would be limited to approximately I 0 minutes in length because the V 0 

would require the last 30 minutes to satisfy section 91.151 (a). 

AA Energy believes that an exemption from 14 C.F.R. § 91.151 (a) provides an equivalent level of 

4 Exemption Nos. t t 156, It 158, 11159.

east 30 minutes of flight time, if not 

more, would be more than adequate to return the UAS to its planned landing zone from anywhere in its 

limited operating area. 5 

14 C.F.R. §§ 91.405(a), 91.407(a)(l ), 91.409(a)(2), and 91.417(a): Maintenance Inspections 

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 discrepancies 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 airworthiness 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. 

Pre-flight checks will be performed by a qualified person prior to each flight and at predefined intervals 

as part of the maintenance schedule. 

The pre-flight checklist includes: 

I. Visual inspection of the airframe; 

2. Visual inspections of propeller(s); 

3. Verify GPS acquisition; 

4. Plan and upload mission; 

5. Camera and payload check; 

6. Controls check; 

7. Gyro/control surfaces check; 

8. Throttle check; 

9. Check sensors; and 

10. Verify failsafes are set correctly. 

An equivalent level of safety will be achieved because the UAS will operate only in restricted 

predetermined areas, and at low altitudes. In addition, the operator 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. Test flights will be conducted prior to operations following adjustments 

to UAS hardware, software, or firmware. 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

at a ground speed exceeding 60 kts. 

3) The UAS will not be operated at an altitude more than 200 feet above the highest 

predominant terrain except as may be provided by FAA Air Traffic Control (11ATC") 

via GOA. The highest predominant terrain is defined as terrain within l mile of the 

launch point and within the visual line of sight of the VO. All altitudes reported to 

A TC shall be in feet AGL. 

4) All operations must use a MO. The MO and VO must be able to communicate 

verbally at all times. The VO must be designated before the flight. The VO must 

ensure that the MO can perform the functions prescribed in the operating documents. 

5) The operating documents and this grant of exemption must be accessible during UAS 

operations and made available to the Administrator upon request. If a conflict exists 

between the conditions and limitations in the exemption and the procedures outlined 

in the operating documents, the conditions and limitations in the exemption take 

precedence and must be followed. Otherwise, AA Energy must follow the procedures 

as outlined in its operating documents. AA Energy may update or revise its operating 

documents. It is AA Energy's responsibility to track such revisions and present 

updated and revised documents to the Administrator upon request. AA Energy must 

also present updated and revised documents if it petitions for extension or amendment 

to this grant of exemption. 

6) Prior to each flight the VO must inspect the UAS to ensure that it is in a condition for 

safe flight. The VO shall not operate the aircraft if the inspection reveals a condition 

that affects the safe operation of the UAS until the necessary maintenance has been 

performed and the UAS is found to be in a condition for safe flight. The Ground 

Control Station, if utilized, must be included in the preflight inspection. All 

maintenance and alterations must be properly documented in the aircraft records. 

7) Any VAS 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 Operator's Manual. The VO who 

conducts the functional test flight must make an entry in the aircraft records of the 

flight. The requirements and procedures for a functional test flight and aircraft record 

entry shall be included in the Operator's Manual. 

8) The pre-flight inspection must account for all discrepancies, e.g. inoperable 

components, items, or equipment, not already covered in the relevant sections of the 

Page 11

aircraft records, including total time in service, description of work accomplished, and 

the signature of the person authorized to return the UAS to service. 

11) Each UAS operated under this exemption must comply with all manufacturer 

Safety Bulletins. 

12) The VO must possess at least valid state-issued motor vehicle driver's license. The 

VO must also meet the flight review requirements specified in 14 C.F.R. § 61.56 in an 

aircraft in which the VO is rated on his or her pilot certificate. 

13) AA Energy may not permit any VO to operate unless the VO meets the operator's 

qualification criteria and demonstrates the ability 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 

persons, vessels, vehicles and structures. 6 VO qualification flight hours and currency 

must be logged in a manner consistent with 14 C.F.R. § 61.51 (b). The VO must 

ensure that the MO is trained appropriately in order to fulfill his or her duties. A 

record of training and qualification must be documented and made available upon 

request by the Administrator. Flights for the purposes of training the operator's VOs 

and MOs (training, proficiency, and experience-building), are permitted under the 

terms of this exemption. However, training operations may only be conducted during 

dedicated training sessions. During training, proficiency, and experience-building 

flights, all persons not essential for flight operations are considered nonparticipants, 

and the VO must operate the UAS with appropriate distance from nonparticipants in 

accordance with these operating conditions. 

14) 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 ("VMC11 ). 

Flights under special visual flight rules ("SVFR") are not authorized. 

15) The UAS may not operate within 5 nautical miles of an airport reference point as 

denoted on a current FAA-published aeronautical chart. 

16) The UAS may not be operated less than 500 feet below or less than 2,000 feet 

horizontally from a cloud or when visibility is less than 3 statute miles from the VO. 

6 Prior documented flight experience that was obtained in compliance with applicable regulations may satisfy this 

requirement.

s must be completed within 30 minutes flight time. 

20) The radio frequency spectrum used for operation and control of the UAS must 

comply with Federal Communication (FCC) or other appropriate government 

oversight agency requirements. 

21) The documents required under 14 C.F.R. §§ 91.9 and 91.203 must be available to 

the VO at the Ground Control Station of the UAS any time the aircraft is operating. 

These documents shall be made available to the Administrator or any law enforcement 

official upon request. 

22) The UAS must remain clear and yield the right of way to all other manned 

operations and activities at all times. 

23) The UAS may not be operated from any moving device or vehicle. 

24) The UAS may not be operated over congested or densely populated areas. 

25) Flight operations must be conducted at least 500 feet from all nonparticipating 

persons, vessels, vehicles, structures, and public access roads unless: 

a. The nonparticipating persons are authorized to access the client's site and are 

wearing personal protective gear; 

b. For non-participants who do not qualify as client employees, barriers or 

structures are present that sufficiently protect them from the UAS and/or debris 

in the event of an accident. The operator must ensure that nonparticipating 

persons who are not client employees remain under such protection. If a 

situation arises where nonparticipating persons who are not client employees 

leave such protection and are within 500 feet of the UAS, flight operations 

must cease immediately; or 

c. The aircraft is operated near vessels, vehicles or structures where the 

owner/controller of such vessels, vehicles or structures has granted permission 

and the VO has made a safety assessment of the risk of operating closer to 

those objects and determined that it does not present an undue hazard. 

26) Operations nearer than 500 feet to the VO, MO, operator trainees or essential 

persons as defined in the operating documents are permitted if those operations do not 

present an undue hazard to those persons per§ 91.119(a) as determined by the VO.

e such option being to fly back to a 

preselected rally point and land). Faults that can be detected include: loss of communication, loss of 

GPS, and low battery levels. In addition, the operator can create no fly zones, and the system will 

visually and audibly warn the operator if the planned flight path would enter the no fly zone. 

Operator's Manual - The Tuffwing Operator's Manual will be provided under separate cover with a 

request for confidential treatment. 

Power- The Tuffwing and its ground control station are both powered by a Lithium polymer 

rechargeable battery pack. A new battery has a fully charged voltage of approximately 12.4V. A "fullpack" has a capacity of 4 Amp-hours. An additional "half-pack" can be installed for extended operation. 

A new "half-pack" has a fully charged voltage of 12.4V and a capacity of2 Amp-hours. The Tuffwing's 

battery charge is displayed in real-time on the ground control terminal, ensuring maximum flight 

duration and safety. 

Takeoff and Landing style/type -The Tuffwing is hand launched. The Tuffwing lands by returning to a 

pre-determined rally point and beginning a spiral descent. Once it reaches a preselected altitude, it heads 

toward the landing waypoint, descending until it lands and skids to a stop or it can manually landed. 

Navigation System- Specific maps can be downloaded to the display screen (such as air sectional and 

geographic maps) which are overlaid with GPS positional data. Waypoints can be created before and 

during flight operation creating specific locations and sequences for the aircraft. 

Defined "Keep Out" Areas - The navigation software allows for preplanning Keep Out Areas that allow 

the operator to designate airspace he or she does not want the Tuffwing to enter. If defined flight paths 

pass through an area designated as keep-out, the individual waypoints and waypoint connection 

segments tum red as a warning. Additionally, if a mission is uploaded and intersects with a keep out 

area, a warning is presented to the user. Also, if an aircraft in flight is navigated into a designated keep 

out area, an audible warning is sounded. 

Maintenance - The Tuffwing UAS needs very little maintenance, and operators may perform most 

required maintenance in the field with the field repair kit. 

Command and Control Systems- The UAS Ground Control Station (GCS) allows the operator 

simultaneous control over aircraft and payloads. The display screen provides all essential flight data to 

the operator. Telemetry data is transmitted to the command station at least once per second. 

Displayed on GCS: 

• Current position 

• Registered home position

eading 

• Communication strength 

• Range from home 

• Bearing from home 

• Duration of current mission 

• Rate of climb 

• Mode of the aircraft 

• Battery level 

Emergency Procedures and System Failures 

Loss of Link- The UAS does not need constant signal from the GCS to continue flying. 

Communications outages are detected by the system and are reported to the VO. During the 

communication outage, the UAS continues on its pre-determined flight path until a failsafe is triggered. 

Once a failsafe is triggered, the UAS will perform in accordance with the failsafe conditions uploaded 

before launch. This is accomplished without input from the operator. 

Security 

The system and communication links are spread spectrum.
