UAS

We are petitioning for exemption to enable TerraForge to operate a DJI Phantom 2, DJI Phantom 3, DJI Inspire 1 and a 3DRobotics Aero fixed wing sUAS. These sUAS all weigh less than 15 lbs, have a built

‐ in capability to limit the height (400 feet AGL) it flies above the ground, to limit the radius of the distance it flies from the operator (Visual Line of Sight or 2000 horizontal feet) and to exclude it from Class B, C and D airspace including a no fly zone feature. Each system also has the failsafe function of the autopilot system, which means when the communication between the Main Controller and the transmitter is lost, the system will automatically trigger Return to Home and will l and in a safe manner

.

The above specifications meet standards listed below, some derived in accordance with the Model Aircraft Operating Standards:



### ■ The petitioner will only operate its sUAS in line of sight of a pilot and/or observer and will operate at
si tes that are a 'sufficient distance' from populated areas within the sterile area described in the operator’s manual. Such operations will insure that the sUAS will "not create a hazard to users of the national airspace system or the public."



### ■ When flying s UAV within 5 miles of an airport, TerraForge shall submit a Plan of Activities to the local Flight Standards District Office (FSDO) at least 3 days before the planned flight in accordance with FAA guidelines.



### ■ Maximum flight time for each operational flight will be 50 minutes.



### ■ Flights will be terminated at 20% battery power reserve should that occur prior to the 50 minute limit.



### ■ The sU AS will be programmed so that it will not be operated at an altitude greater than 400 feet

AGL.



### ■ Minimum crew for each operation will consist of the sUAS Pilot and the Visual Observer.



### ■ The sUAS will operate during daylight hours only.



### ■ The sUAS Pilot will be the Pilot in Command ( PIC ) and will be trained in flight operations , Visual Flight Rules (VFR), and safety procedures

.



### ■ The sUAS operated by the petitioner weighs less than 15 pounds, including the payload (i.e. camera, lens, and gimbal) utilizing FCC compliant devices and frequencies ( 5 GHz, 2.5 GHz

, and 915 MHz)

.



### ■ The sUAS will operate at speeds of no more than 45 knots.



### ■ Given the small size of the sUAS and the restricted environment within which they will operate, our sUAS operations adhere to the Reform Act's safety requirements.FLIGHT OPERATIONS

Flight Limits

Operators should abide by all state, federal and regulator y agencies requirements for flight. In general, a

s UAS should not be operated in wind speeds greater than 10 m/s, or in snow, rain, low cloud cover, and fog.

It is also recommended to avoid all metal structures, power lines, and transmission towers that ma y interfere
with the s UAS compass and GPS.

No

- Fly Zones

It is the operator’s responsibility to fly safely and abide by all state, federal and regulatory agencies requirements. A flight log is required to maintain safe flight operations. An important part o f documenting the flight log is verifying the area is not within a no

- fly zone. Several resources exist online detailing the

locations of no

- fly zones. The following example provides no

- fly zones for the area surrounding Seattle, Washington, provided by http://flysafe.dji.com/no

- fly . It should be noted the use of s UAS inside National Parks is prohibited and may not be reflected on the above listed no

- fly zone maps, as well as other state, and

federal facilities.

Several manufacturers utilize onboard GPS restricting flight in no

- fly zones. The flight controller has the ability to disable take

- off, reduce altitude, and automatically land in some situations. With the use of a ground station, warnings and restrictions will be displayed on the screen.

Additionally, TerraForge has a high regard to safe operations with an understanding of FARs, pre

‐ flight inspections, maintenance and repair, operations within airspace, as well as being trained to high safety

standards

. The use of our sUAS promotes safe and effective data acquisition that would otherwise present

difficulties to alternative methods in remote locations.

Under the requested exemption TerraForge ensures that all operators have conducted a thorough review of

sUAS education material concerning the systems to be operated in addition to all applicable regulations and guidance documents; including aeronautical background information such as charts, NOTAMS and Aircraft Circulars; Radio Communications Procedures; Human Factors and Crew Resource Management; Basic s UAS Aerodynamics; Weather factors; Airmanship and Decision

‐ making and Safe Operating Procedures.

We respectfully request exemption under Section 333 to enable TerraForge to operate safe, low

‐ risk
commercial sUAV operations for the activities stated.

- 1719EXEMPTION REQUESTS

TerraForge Systems

, LLC . requests an exemption from the following regulations as well as any additional regulations that may apply to the operation of the sUAS :

14 CFR 61.113 (a) & (b)

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

‐ commercial operations. TerraForge proposes that its sUAS PIC will have complete a flight

- training program and at least 15

‐ Hours of flight time in a safe and controlled environment prior to operating the sUAS commercially. The airmanship skills necessary to operate

the sUAS do not correlat e significantly to the airmanship skills necessary for piloting manned aircraft and, thus, exemption from the need for the PIC to hold a commercial pilot certificate is requested. Unlike a conventional aircraft that carries the pilot and passengers, the sU AS is remotely controlled with no living thing on board. The areas of operation will be restricted to jobsites at which third party access is controlled, and all flights are planned and coordinated in advance. The risks associated with the operation of the sUAS are diminished from the level of risk associated with commercial operations contemplated by Part 61 when drafted, that allowing operations of the sUAS as requested with a private pilot as the PIC exceeds the present level of safety achieved by 14 C.F .R. §61.113 (a) & (b). In addition, the PIC will undergo all necessary security screenings by the Transportation Security Administration that certificated airmen undergo. The FAA has granted exemptions for private pilots to conduct similar operations in Ex emptions 11062, 11213, 11360
and 11447.

14 CFR 91.9

This regulation provides that no person may operate an aircraft unless a current, approved flight manual is in the aircraft. We assume that the intent of this requirement is to ensure that flight manual i nformation is available to the aircrew while operating the aircraft. We request an exemption to this requirement since the aircraft is not only too small to carry documentation, the documentation would not be available to the crew during flight operations. To obtain an equivalent level of safety and meet the intent of 91.9, we propose that a current, approved sUAS Flight Manual must be available to the crew at the ground station anytime the aircraft is in, or preparing for, flight.

14 CFR 91.109

The regulation states, "No person may operate a civil aircraft that is being used for flight instruction unless that aircraft has fully functioning dual controls." The sUAS System ground

‐ based control station consists of a
small hand

‐ held radio transmitter and while it does not offer a second set of "controls", both the student and instructor can, and will, operate the single set of controls simultaneously. With both student and instructor having "hands

‐ on" the controls during flight, we feel that this tech nique meets the intent 91.109 and provides an equivalent level of safety.

14 CFR 91.119

The regulation states that over sparsely populated areas the aircraft cannot be operated closer than 500 feet to any person, vessel, vehicle, or structure. Since the ty pical mission of the sUAS would be photography or survey of persons, vessels, vehicles or structures it would be necessary to operate closer than 500 feet to the items listed. Operations will only be flown over property or persons where permission has been obtained and careful pre

‐ planned has been performed. The aircraft will be operated at a low altitude allowing, if a power unit fails, an emergency landing without undue hazard to persons or property on the surface. Therefore, we maintain that due to the s mall size of the UAS, the hazard to persons, vehicles and structures is minimal compared to manned aircraft, which should be considered in granting the exemption.14 CFR 91.121

The regulation requires that aircraft shall maintain cruising altitudes by refe rence to an altimeter setting available within 100 NM of the aircraft. The sUAS will always fly below 400 feet AGL and will not need to maintain cruising altitudes in order to prevent conflict with other aircraft. An Above Ground Level altimeter

measuremen t above the takeoff point is transmitted via radio from the sUAS on

‐ board computer to the display screen held by the PIC, providing a constantly updated AGL readout.

14 CFR 91.151

The regulation provides that no person may begin a flight in an airplane und er day

‐ VFR conditions unless there is enough fuel to fly to the first point of intended landing and to fly after that for at least 30

- minutes. We feel the intention of this paragraph is to provide an energy reserve as a safety buffer for delays to landing. The sUAS are battery operated and the maximum duration of flight from a single battery charge is 12

‐ 45 (depending on which sUAS) minutes with a 20% reserve. Since the aircraft will never fly more than 1/2 NM from the point of intended landing, a full batt ery charge at launch will ensure that we meet the reserve energy requirement of this paragraph. We request an exemption to the word "fuel" and ask for an equivalent interpretation with the word "energy". We also request exemption from the 30

- minute reserve and ask that our reserve will be to fly the mission to the point of intended landing and have at least a 20% battery reserve after

that.

14 CFR Subpart E (91.401

‐ 91.417)

The regulation provides that the operator is primarily responsible for maintaining the aircraft in an airworthy condition, including compliance with part 39 and 43. Paragraphs 91.407 and 91.409 require that the aircraft be "approved for return to service b y a person authorized under 43.7" after maintenance and inspection. It is our intention that the PIC perform maintenance and inspection of the aircraft and "be authorized to approve

the aircraft for return to service." The PIC will ensure that the aircraft is in an airworthy condition prior to every flight and in addition, conduct detailed inspections after every 10 hours of flight or manufacturer

recommendations . Maintenance performed by the PIC is limited to repairing small cracks, replacing propeller s , c hecking electrical connections and updating software and firmware for the on

‐ board computer. All other maintenance will be performed by the manufacturer or their designated repair facility. The PIC will document work performed in accordance with 91.417. We feel that due to the size, construction, and simplicity of the aircraft, the PIC can ensure an equivalent level of safety.
