Characteristics of the s UAS

The DJI Phantom 3 Professional is small, safe, and light weight electric powered quadcopter. It only weighs 2.8 pounds and measures about 27 inches across diagonally, includ ing the props. It is powered by a 4480 mAh4s LiPo battery that has a max flight time of approximately 23 minutes. The max flight speed is about 36 mph. This system contains an onboard GPS system that receives both GPS and
GLONASS satellites and an inertia l measurement unit. These features help maintain safe flight stabilization and automatic failsafe return to home in the event of a lost control signal or low battery.
This s UAS also has the ability to apply user defined max flying height altitudes as well as vertical limits to
the controller. The in

- built app notifies the user if the s UAS is in a restricted or no

- fly zone.

The pilot in command (PIC) has critical information available to him throughout each flight that are pertinent safety. Information su ch as the sUAS battery life, battery temperature in flight, vertical and horizontal flight distances, live image feed of camera view, number of satellites in view, and signal strength to controller are all visible on the controller.

The Phantom 3 records all flight times and battery cycle information. With this information Ensign will
follow the sUAS manufacturer’s maintenance, overhaul, replacement, inspection, and life limit requirements for the aircraft and aircraft components as well as all applicabl e instructions in the user manuals. Additionally Ensign will be able to monitor the health of the s UAS’s power source to ensure reliability for each operation. When the sUAS has undergone repairs, maintenance, and software/firmware updates or any other alt erations that affect s UAS operation or flight characteristics, it will undergo a functional test flight prior to any commercial flights. The PIC and a visual observer will conduct the functional test flight at least 500 feet from other people in an area t hat won’t pose any undue hazards to persons and property.

The PIC will conduct a pre

- flight inspection to account for all potential discrepancies and to determine if
the s UAS is in a condition safe for flight prior to each flight. If the inspection reve als anything that affects a safe operation of the s UAS, the PIC will immediately cancel the flight and the s UAS will be taken out of operation until the necessary repairs or maintenance has been completed and has been determined safe to fly.

Ensign will comply with all manufacturer safety bulletins relating to the Phantom 3.

This aircraft will be identified by a serial number, registered in accordance with 14 CFR part 47, and have clear identification markings as large as practicable in accordance with 1 4 CFR part 45, Subpart C.

UAS PIC Requirements

Ensign will require every PIC to hold either an airline transport, commercial, private, recreational, orSALT LAKE CITY

The PIC will also hold a current FAA airman medical certificate or a valid U.S. driver’s license issued by a state, the District of Columbia, Puerto Rico, a territory, a possession, or the Federal government. The PIC will also meet the flight review requirements specified in 14 CFR § 61.56 in
an aircraft in which the PIC is rated on his or her pilot certificate.

Ensign will provide internal ground and flight training to each PIC. Ensign will require each pilot to achieve a high level of operating proficiency. Any PIC will not be permitted to operate if the PIC doesn’t
demonstrat es the ability to safely operate the s UAS in a manner consistent with how the s UAS will be operated under this exemption, including evasive and emergency maneuvers and maintaining appropriate distances from persons, vessels, vehicles and structures. Recurr ent training will be held annually (at minimum) to review current or new regulations and issues pertinent to commercial operation of the Phantom 3 in The National Airspace System (NAS)

.

The PIC will use a preflight checklist prior to each flight, this ch ecklist is attached to this petition. The PIC will be designated before the flight and won’t transfer this designation for the duration of the entire flight.

Attached is the name and pilot license number for the current designated pilot on staff.

UAS op erating constraints

Upon being granted exemption to operate the Phantom 3 Ensign will only conduct flights in safe to fly conditions as outlined below. Ensign will ensure each PIC is trained on how to successfully meet each requirement consistently.

- The s UAS shall only be permitted to operate when weighing less than 55 pounds including payload.

- The s UAS shall never exceed 87 knots (100 mph). In no case will the sUAS be operated at airspeeds greater than the maximum operating airspeed recommended b y the aircraft manufacturer.

- The s UAS will be operated at an altitude of no more than 400 feet above AGL. This operating height limit will defined in Phantom 3 internal settings and the aircraft will be restricted to this limit.

Description of regulations requiring exemption

Ensign requests an exemption from the following regulations as well as any additional regulations that
may technically apply to the operation of the Phantom 3.

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

Section 91.203 requires all civil aircraft to have a certificate of airworthiness. Part 21, Subpart H, entitled
Airworthiness Certificates, establishes the procedural requirements for the issuance of airworthiness

c ertificates as required by FAR § 91.203(a). Given the size of the P hantom 3 , its light weight, and the
limited operating area associated with its utilization, it is unnecessary to go through the certificate of
airworthiness process under Part 21 Subpart H in order 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

Phantom 3 involved. An analysis of these different cri teria demonstrates that the Phantom 3 operated
without an airworthiness certificate, under the conditions proposed in that exemption, will be at least as
safe, or safer, than a conventional aircraft with an airworthiness certificate

.

14 C.F.R. § 61.3: Req uirements for certificates, ratings and authorizations 14 C.F.R. § 61.113(a) & (b);
61.133(a): Private Pilot Privileges and Limitations; Pilot in Command; Commercial Pilot Privileges and

Limitations

The regulation provides that no person may serve as a r equired pilot flight crewmember of a civil aircraft
of the United States, unless that person: (1) Has a pilot certificate or special purpose pilot authorization
issued under this part in that person's physical possession or readily accessible in the aircra ft when
exercising the privileges of that pilot certificate or authorization. However, when the aircraft is operated
within a foreign country, a pilot license issued by that country may be used. The regulation provides also
that no person that holds a priv ate pilot certificate may act as pilot in command of an aircraft for
compensation or hire. Subparagraph (b) allows a private pilot to act as pilot in command of an aircraft in
connection with any business or employment if: (1) The flight is only incidental to that business or
employment; (2) The aircraft does not carry passengers or property for compensation or hire.

Given the size, weight, speed, operational limitations, and range of the Phantom 3

, Ensign proposes that

each PIC of the Phantom 3 should no t be required to hold a commercial pilot certification. Instead,
operators should be required to hold at least an FAA issued private, recreational, or sport pilotSALT LAKE CITY

certificate. Each PIC will meet the flight review requirements specified in 14 CFR § 61.56 as well as
Ensign’s internal training standards

.

14 C.F.R. § 91.9: Civil aircraft flight manual, marking, and placard requirements.

This regulation provides that no person may operate an aircraft unless a current, approved flight manual

is in the aircraft. Ensign proposes to uphold an equivalent level of safety by keeping a copy of all
documents used by the PIC to ensure the safe operation and flight of the Phantom 3 as well as
documentation of an exemption and COA with the ground control station. This info rmation will be

available to the PIC during each flight operation

.

14 C.F.R. § 91.103: Preflight action

This regulation requires that each pilot in command shall, before beginning a flight, become familiar
with all available information concerning that f light. This information must include runway lengths at
airports of intended use, and takeoff and landing distance information.

Ensign will not permit any sUAS operations at an airport due to potential high risk safety hazards that

are in volved in the airp ort environment. An equivalent level of safety will be achieved as Ensign requires
the PIC to conduct preflight inspections prior to each flight while using the manufacture’s preflight

checklist. The PIC will also assess current weather conditions to make sure it will be safe to fly.

14 C.F.R § 91.105: Flight Crewmembers at Stations

This regulation states that each crewmember needs to be at their required stations at certain times of the flight and must safely harnessed or fastened in seat.

Due to the fact that the Phantom 3 can’t carry any passengers this regulation is not applicable. To achieve an equivalent level of safety the PIC will be designated prior to each flight and will remain as PIC for the duration of each flight. The PIC will also not ope rate from a moving vehicle and will be in position to remain in VLOS throughout the duration of each flight.

14 C.F.R. § 91.109(a): Flight Instruction

The regulation states that "No person may operate a civil aircraft that is being used for flight instru ction unless that aircraft has fully functioning dual controls."

The Phantom 3 does not carry any crew members and it is not possible to provide flight instruction in the aircraft. Ensign will provide an equivalent level of safety during flight training b y operating training flights in a tightly controlled environment in remote areas away from persons, vehicles, or buildings

. DJI also provides a digital flight simulator for pilots in training to gain experience on before taking flight.SALT LAKE CITY

14 CFR § 91.119: M inimum Safe Altitudes

The regulation describes the safe flying altitudes over congested areas requires the aircraft to be 1000 ft AGL above the highest obstacle within a horizontal radius of 2,000 feet. Other areas the aircraft needs to
be at 500 ft AGL a nd not closer than 500ft to any person, vessel, vehicle, or structure.

This regulation is not applicable to the 333 exemption petition as Ensign is requesting a max altitude of
400 feet AGL. An equivalent level of safety will be accomplished d ue to the p hysical characteristics of the Phantom 3 and the type of project areas it will be working in. This aircraft will be operated in areas that if a power source fails, and emergency landing won’t pose any undue hazard to persons or
property.
14 CFR 91.121

– Al timeter settings

This regulation requires that each person operating an aircraft shall maintain the cruising altitude or flight level of that aircraft, as the case may be, by reference to an altimeter that is set, when operating below 18,000 feet MSL to:

- The current reported altimeter setting of a station along the route and within 100 nautical miles of the aircraft;

- If there is no station within the area prescribed in paragraph (a)(1)(i) of this section, the current reported altimeter setting of an app ropriate available station;

- In the case of an aircraft not equipped with a radio, the elevation of the departure airport or an appropriate altimeter setting available before departure.

To provide a level of safety equivalent to this regulation the Phanto m 3 uses internal gyroscopes, barometric pressure sensors, and a GPS system to calculate the altitude.

14 C.F.R. § 91.151(a) &(b)

This regulations states that no person may begin a flight in an airplane under VFR conditions unless (considering wind and fo recast weather conditions) there is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed d uring the day, to fly after that for at least 30 minutes; or at night, to fly aft er that for at least 45 minutes. It also sta tes that no person may begin a flight in a rotorcraft 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, to fly after that f or at least 20 minutes.

In order to achieve a level of safety equivalent to this regulation, Ensign will require the PIC to asses wind and forecasted weather conditions prior to each flight. The PIC won’t begin a flight unless there is enough available pow er for the sUAS to conduct the intended operation and to operate after that for at least five minutes or with the reserve power recommended by the manufacturer if greater.

This regulation states no person may operate a civil aircraft unless it has an appropriate and current airworthiness certificate. Additionally no person may operate a civil aircraft unless the airworthiness certificate required by paragraph (a) of this se ction 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.

Ensign proposes to maintain a copy of all documents used by the operator to ensure the safe operation

an d flight of the phantom 3 (owner’s manual and checklists), any documents relating to the aircraft registration in accordance with 14 CFR part 47, and documentation of an exemption and COA with the ground control station and these will be available to the A dministrator or any law enforcement official
upon request.

14 CFR 91, Subpart E (91.405, 91.407, 91.409, 91.417)

- Maintenance, Preventive Maintenance, and
Alterations

The regulation states that the operator is primarily responsible for maintaining the a ircraft in an airworthy condition, including compliance with Parts 39 and 43. Paragraphs 91.407 and 91.409 require that the aircraft be "approved for return to service by a person authorized under 43.7" after maintenance and inspection. 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 the maintenance work that has been completed by certificated mechanics, under Part 43, or licensed p ilots and records of approval of the aircraft for return to service.

Ensign will require that any maintenance completed on the Phantom 3 will be approved by and m e et the satisfaction of the PIC. All maintenance conducted will be logged in accordance with the manufacture’s conditions. This will achieve an equivalent level of safety because the Phantom 3 is small in size, are not as complex as full size mechanical aircraft.

Applications and Public Interest

The requested exemption would permit Ensign to con duct commercial operations using the Phantom 3
for mapping, inspection and photography of construction sites, volumetric calculations, agriculture, surveying, planning, and design.

Currently manned aircraft can be used to accomplish the same type of work . Using manned aircraft has high risk potential for undue safety hazards for the crew on board the aircraft and other persons, vessels, vehicles and structures in the air or on ground. Also, using manned aircraft is not always feasible for every applicatio n as the cost associated with operating that type of equipment is high. Additionally, using manned aircraft can cause extra pollutants to be emitted into the environment while conducting
the work.

Using sUAS to accomplish this work has much lower risk f or undue safety hazards given the size, weight, and speed of these systems. T he cost to operate sUAS’s are significantly less than traditional manned
aircraft methods. Due to how the Phanto m 3 is powered using a battery , it is a much greener alternative

to manned aircraft and contribute substantially less pollutants and greenhouse gases into the

environment. With sUAS’s a high quality product can be created at a fraction of the cost in a much saferSALT LAKE CITY

Conclusion

Ensign respectfully requests that the FAA grant the exemption pursued in this request. Considering the physical and safety characteristics of the Phantom 3 and the PIC training and operating requirements stated above demonstrates Ensign will operate the Phantom 3 within NAS following the constraints outlined by the FAA at a level of safety that is greater or comparable to traditional manned aircraft.
