Characteristics of the sUAS

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, including 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 inertial 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 sUAS 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 sUAS 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 such 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 applicable instructions in the user 

manuals. Additionally Ensign will be able to monitor the health of the sUAS’s power source to ensure 

reliability for each operation. When the sUAS has undergone repairs, maintenance, and 

software/firmware updates or any other alterations that affect sUAS 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 that 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 sUAS is in a condition safe for flight prior to each flight. If the inspection reveals anything that affects 

a safe operation of the sUAS, the PIC will immediately cancel the flight and the sUAS 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 14 CFR part 45, Subpart C. 

UAS PIC Requirements

Ensign will require every PIC to hold either an airline transport, commercial, private, recreational, or

sport pilot certificate. 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 

demonstrates the ability to safely operate the sUAS in a manner consistent with how the sUAS will be 

operated under this exemption, including evasive and emergency maneuvers and maintaining 

appropriate distances from persons, vessels, vehicles and structures. Recurrent 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 checklist 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 operating 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 sUAS shall only be permitted to operate when weighing less than 55 pounds including payload.

- The sUAS shall never exceed 87 knots (100 mph). In no case will the sUAS be operated at airspeeds 

greater than the maximum operating airspeed recommended by the aircraft manufacturer.

- The sUAS 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. 

- The sUAS will be operated within visual line of sight (VLOS) of the PIC at all times. The PIC will use 

human vision unaided by any device other than corrective lenses, as specified on the PIC’s FAA-issued 

airman medical certificate or U.S. driver’s license.

-All flight operations will utilize a visual observer (VO). The sUAS will be operated within the VLOS of the 

PIC and VO at all times. The VO and PIC will be able to communicate verbally at all times. No electronic 

messaging or texting is permitted during flight operations. The PIC will ensure that the VO can perform 

the duties required of the VO.

-All documents needed to operate the sUAS and conduct its operations in accordance with the 

conditions and limitations stated in the grant of exemption will be accessible during all sUAS operations

and made available to the Administrator upon request. Any updated and revised documents will be 

tracked and presented to Administrator or any law enforcement official upon request.

-All sUAS operations will be conducted only during daytime conditions, as defined in 14 CFR § 1.1. All 

operations will be conducted under visual meteorological conditions (VMC). Flights under special visual 

flight rules (SVFR) will not occur. The sUAs won’t 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 PIC.

- The sUAS will not operate within 3 nautical miles of an airport reference point (ARP) as denoted in the 

current FAA Airport/Facility Directory (AFD) or for airports not denoted with an ARP, the center of the 

airport symbol as denoted on the current FAA-published aeronautical chart, unless a letter of agreement 

with that airport’s management is obtained or otherwise permitted by a COA issued to Ensign. The letter 

of agreement with the airport management must be made available to the Administrator or any law 

enforcement official upon request.

- If the sUAS loses communications or loses its GPS signal, the sUAS will return to a pre-determined 

location within the private or controlled-access property.

- The PIC will be prohibited from beginning a flight unless there is enough available power 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.

- Documents used by Ensign to ensure the safe operation and flight of the sUAS and any documents 

required under 14 CFR §§ 91.9 and 91.203 will be available to the PIC at the Ground Control Station of 

the sUAS any time the aircraft is operating. These documents will be made available to the 

Administrator or any law enforcement official upon request. 

- The sUAS will remain clear and give way to all manned aviation operations and activities at all times.

- The sUAS will not be operated by the PIC from any moving device or vehicle.

- The sUAS will not be operated directly over nonparticipating persons unless barriers or structures are 

present that sufficiently protect nonparticipating persons from the sUAS and/or debris in the event of an 

accident. The sUAS will not be operated over any open-air assembly of people.

-The only flight operations conducted within 500 feet of any vessels, vehicles or structures are when 

Ensign has been granted permission and when the PIC has made a safety assessment of the risk of 

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

- Any incident, accident, or flight operation that transgresses the lateral or vertical boundaries of the 

operational area as defined by the applicable COA must be reported to the FAA's sUAS Integration Office 

(AFS−80) within 24 hours. Accidents must be reported to the National Transportation Safety Board 

(NTSB) per instructions contained on the NTSB Web site: www.ntsb.gov.

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: Airworthiness 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 

certificates as required by FAR § 91.203(a). Given the size of the Phantom 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 criteria 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: Requirements 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 required 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 aircraft 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 private 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 not be required to hold a commercial pilot certification. Instead, 

operators should be required to hold at least an FAA issued private, recreational, or sport pilot

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 information 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 flight. 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 involved in the airport 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 operate 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 instruction 

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 by 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.

14 CFR § 91.119: Minimum 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 and 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 due to the physical 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 – Altimeter 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 appropriate 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 Phantom 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 forecast weather conditions) there is enough fuel to fly to the first point of 

intended landing and, assuming normal cruising speed during the day, to fly after that for at least 30 

minutes; or at night, to fly after that for at least 45 minutes. It also states 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 for 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 power 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 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.

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

and 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 Administrator 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 aircraft 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 pilots 

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 meet 

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 conduct 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 application 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 for undue safety hazards given the size, weight, 

and speed of these systems. The cost to operate sUAS’s are significantly less than traditional manned 

aircraft methods. Due to how the Phantom 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 safer

way that traditional manned aircraft methods. 

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.
