BACKGROUND

Unmanned Aircraft Systems: DJI Phantom 3 Professional

Nathan Silsbee seeks an exemption to operate DJI systems for compensation or hire 

within the NAS. The DJI Phantom 3 Professional is a vertical takeoff and landing (VTOL) 

Unmanned Aircraft (UA) with a Ground Control Station (GCS) utilizing electronic tablet 

or smart phone systems. The DJI Phantom 3 Professional has a maximum gross weight of 

approximately 2 pounds 11 ounces, while having a length of 16 inches width of 16 inches, 

height of 8 inches, and a maximum speed of approximately 29 knots. The DJI Phantom 3 

Professional is equipped with four main rotors; driven by Lithium Polymer battery

powered electric motors. 

The DJI Phantom 3 Professional UAS that will be operated by Nathan Silsbee 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.

BASIS FOR PETITION

Petitioner, Nathan Silsbee, pursuant to the provisions of the Federal Aviation 

Regulations (14 C.F.R. § 11.61) and the FAA Modernization and Reform Act of 2012 

(FMRA), Section 333, Special Rules for Certain Unmanned Aircraft Systems, hereby 

petitions the Administrator to commercially operate the DJI Phantom 3 Professional UAS

in the National Airspace System (NAS), and for an exemption from the requirements of 14 

C.F.R §§ 61.113(a) & (b), 91.7(a), 91.121, 91.151(b), 91.405(a), 91.407(a)(1), 

91.409(a)(1) & (a)(2), and 91.417(a) & (b). 
6

In consideration of the speed, weight, size, and limited operating area associated 

with the unmanned aircraft and its operation, Nathan Silsbee’s operation of DJI Phantom 3 

Professional UAS meets the conditions of FMRA Section 333 and therefore, will not 

require an airworthiness certificate in accordance with 14 C.F.R. Part 21, Subpart H. 

Accordingly, Nathan Silsbee requests relief from Sections 91.405(a), 91.407(a)(1), 

91.409(a)(1) & (a)(2), and 91.417(a) & (b), as these sections set forth requirements for 

maintenance that only apply to aircraft with an airworthiness certificate. 

Nathan Silsbee submits that the requested relief is proper since an equivalent level 

of safety will be ensured. Nathan Silsbee will use experienced personnel or technicians to 

perform maintenance, alterations, or preventive maintenance on the UASs using the 

methods, techniques, and practices prescribed in the operating documents (i.e., Monthly

Maintenance Log, and DJI Phantom 3 Professional Instruction Manual). Furthermore, 

Nathan Silsbee will document and maintain all maintenance records for the DJI Phantom 3 

Professional UAS. 

Relief from certain requirements of Section 61.113(a) and (b), entitled Private pilot 

privileges and limitations: Pilot in command, is requested by Nathan Silsbee to the extent 

necessary to allow a Pilot in Command (PIC) holding a private pilot or higher level 

certificate, as well as an airman medical certificate, and who has demonstrated, by meeting 

minimum flight- hour and currency requirements, that the PIC is able to safely operate the 

DJI Phantom 3 Professional UAS in a manner consistent with this exemption, including 

evasive and emergency maneuvers and maintaining appropriate distances from people, 

vessels, vehicles and structures. 
7

Nathan Silsbee seeks relief from Section 91.7(a), entitled Civil aircraft 

airworthiness, because the DJI Phantom 3 Professional UAS does not require an 

airworthiness certificate in accordance with 14 C.F.R. Part 21, Subpart H. As such, Nathan 

Silsbee submits that he will ensure that the DJI Phantom 3 Professional UAS is in an 

airworthy condition, prior to every flight, by determining that the UAS is in compliance 

with the operating documents (i.e., Monthly Maintenance Log, and DJI Phantom 3 

Professional Instruction Manual), and that the aircraft is in a condition for safe flight. 

Nathan Silsbee also seeks an exemption from the requirements of Section 91.121, 

entitled Altimeter Settings, as the DJI Phantom 3 Professional UA will not have a typical 

barometric altimeter onboard. However, altitude information of the DJI Phantom 3 

Professional UA will be provided to the PIC via Global Positioning System (GPS) 

equipment and radio communications telemetry data link, which downlinks from the UA to 

the GCS for active monitoring of the flight path. This altitude information, combined with 

Nathan Silsbee’s operation of the DJI Phantom 3 Professional UAS within visual line of 

sight, at or below 400 feet AGL, will ensure a level of safety equivalent to Section 91.121. 

Additionally, Nathan Silsbee seeks an exemption from the requirements of Section 

91.151(b), entitled Fuel requirements for flight in VFR conditions. Nathan Silsbee submits 

that safety will not be affected by operation of the DJI Phantom 3 Professional UA during 

daylight hours in visual meteorological conditions (VMC) under visual flight rules (VFR), 

with enough battery power to fly for a total duration of approximately 13.5 minutes to the 

first point of intended landing and, assuming normal cruising speed, to fly after that for at 

least 4.5 minutes. 
8

C. The Extent Of Relief Nathan Silsbee Seeks And The Reason Nathan Silsbee Seeks 

The Relief. 
12

1. Extent Of Relief Nathan Silsbee Seeks And The Reason Nathan Silsbee

Seeks Relief From Section 61.113(a) And (b). 

Relief from Section 61.113(a) and (b) entitled Private pilot privileges and 

limitations: Pilot in command, is requested to the extent necessary to allow a PIC holding a 

private pilot or higher level certificate, as well as a current and valid airman medical 

certificate, and who has met certain flight-hour and currency requirements, to conduct the 

proposed UAS flight operations for compensation or hire. 

This relief is requested since the limitations set forth in Section 61.113(a) and (b) 

state that a private pilot may, for compensation or hire, act as PIC of an aircraft in 

connection with any business or employment if: (1) The flight is only incidental to that 

business or employment; and (2) The aircraft does not carry passengers or property for 

compensation or hire. 

As set forth more fully below, Nathan Silsbee submits that an equivalent level of 

safety will be maintained because no PIC will be allowed to operate the DJI Phantom 3 

Professional UAS unless that PIC has met certain flight-hour and currency requirements, 

demonstrating that the PIC is able to safely operate the DJI Phantom 3 Professional UAS 

in a manner consistent with the operations specifications as described in this exemption, 

including evasive and emergency maneuvers, as well as maintaining appropriate distances 

from people, vessels, vehicles and structures.

Further, Nathan Silsbee submits that all flights of the DJI Phantom 3 Professional

UAS, conducted by the PIC pursuant to the grant of this Petition: (1) will be incidental to 

Nathan Silsbee’s business; and (2) will not carry passengers or property for compensation 

or hire. 
13

2. Extent Of Relief Nathan Silsbee Seeks And The Reason Nathan Silsbee

Seeks Relief From Section 91.7(a). 

Relief from Section 91.7(a) entitled Civil aircraft airworthiness, is requested to the 

extent required to allow Nathan Silsbee to determine that the DJI Phantom 3 Professional

UAS is in airworthy condition prior to every flight by ensuring that the UAS is in 

compliance with the operating documents (i.e., Monthly Maintenance Log, and DJI 

Phantom 3 Professional Instruction Manual). 

Nathan Silsbee seeks the requested relief because the DJI Phantom 3 Professional

UAS does not require an airworthiness certificate in accordance with 14 C.F.R. Part 21, 

Subpart H. Therefore, Nathan Silsbee will ensure that the DJI Phantom 3 Professional

UAS is in airworthy condition based upon its compliance with the operating documents 

(i.e., Monthly Maintenance Log, and DJI Phantom 3 Professional Instruction Manual) prior 

to every flight, and further, determine that the aircraft is in condition for safe flight, as 

stated in the conditions and limitations below.

3. Extent Of Relief Nathan Silsbee Seeks And The Reason Nathan Silsbee

Seeks Relief From Section 91.121. 

Relief from Section 91.121, entitled Altimeter settings, may be required to allow 

flight operations of the DJI Phantom 3 Professional UAS, which utilize a barometric 

pressure sensor, GPS equipment, and a radio communications telemetry data link to 

downlink altitude information from the UA to the PIC at the ground control station (GCS). 

Since the FAA requires that any altitude information concerning UAS operations be 

reported to air traffic control (ATC) in feet above ground level (AGL), Nathan Silsbee

seeks the requested relief because the DJI Phantom 3 Professional UA altimeter may be set 

on the ground to zero feet AGL, rather than the local barometric pressure or field altitude, 

before each flight. 
14

Considering the limited altitude of the proposed operations, relief from 14 CFR 

91.121 is sought to the extent necessary to comply with the applicable conditions and 

limitations stated below. As more fully set forth herein, an equivalent level of safety will 

be maintained since the DJI Phantom 3 Professional UA is equipped with a barometric 

pressure sensor and GPS equipment, which automatically ensures that a ground level 

pressure setting will be established prior to each flight, and provides the PIC with altitude 

information of the UA on the heads-up display of the GCS. 

4. Extent Of Relief Nathan Silsbee Seeks And The Reason Nathan Silsbee

Seeks Relief From Section 91.151(b). 

Relief from Section 91.151(b) entitled Fuel requirements for flight in VFR 

conditions, is requested to the extent required to allow flights of the battery powered DJI 

Phantom 2 Vision UA during daylight hours in visual meteorological conditions (VMC), 

under visual flight rules (VFR), for a total duration of 13.5 minutes to the first point of 

intended landing and, assuming normal cruising speed, to fly after that for at least 4.5 

minutes. Nathan Silsbee seeks the requested relief because without an exemption from 

Section 91.151(b), the flight time duration of the battery powered DJI Phantom 3 

Professional UA will severely constrain the practicality of any aerial video or still photo 

flight operations that Nathan Silsbee proposes to conduct pursuant to this Petition. 

Significantly, as set forth below, the technical specifications of the DJI Phantom 3 

Professional UAS, the DJI Phantom 3 Professional operating documents, and Nathan 

Silsbee’s proposed operating limitations, ensure that Nathan Silsbee will safely operate the 

battery powered DJI Phantom 3 Professional UA during daylight hours in visual 

meteorological conditions (VMC), under visual flight rules (VFR), with enough battery
15

power to fly for a total duration of 13.5 minutes to the first point of intended landing and, 

assuming normal cruising speed, to fly after that for at least 4.5 minutes.

5. Extent Of Relief Nathan Silsbee Seeks And The Reason Nathan Silsbee

Seeks Relief From Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), 

And 91.417(a) & (b). 

Since Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) 

only apply to aircraft with an airworthiness certificate, Nathan Silsbee requests relief from 

these Sections because the DJI Phantom 3 Professional UAS does not require 

airworthiness certificates. As set forth more fully below, the DJI Phantom 3 Professional

UAS meets the conditions of FMRA Section 333 for operation without an airworthiness 

certificate. Accordingly, Nathan Silsbee will use trained technicians to perform 

maintenance, alterations, or preventive maintenance on the UASs using the methods, 

techniques, and practices prescribed in the UAS operating documents (i.e., Monthly

Maintenance Log, and DJI Phantom 3 Professional). Furthermore, Nathan Silsbee will 

document and maintain all maintenance records for the DJI Phantom 3 Professional UAS. 

D. The Reasons Why Granting Nathan Silsbee’s Request Would Be In The Public 

Interest; That Is, How It Would Benefit The Public As A Whole. 

Granting the present Petition will further the public interest by allowing Nathan 

Silsbee to safely, efficiently, and economically perform aerial video and photography of 

construction sites, real estate, and landscape over certain areas of the United States. 

Additionally, use of the DJI Phantom 3 Professional UAS will decrease congestion 

of the NAS, reduce pollution, and provide significant benefits to the economy. Notably, the 

benefits of Nathan Silsbee’s proposed operation of the DJI Phantom 3 Professional UAS

will be realized without implicating any privacy issues. 

1. The Public Will Benefit From Decreased Congestion Of The NAS. 
16

The DJI Phantom 3 Professional UA is battery powered and serves as a safe, 

efficient, and economical alternative to the manned aircraft traditionally utilized to obtain 

aerial imagery. By reducing the amount of manned aircraft needed to perform aerial 

acquisitions, an exemption allowing the use of a DJI Phantom 3 Professional UAS would 

reduce the amount of manned aircraft in the NAS, reduce noise and air pollution, as well as 

increase the safety of life and property in the air and on the ground. 

Furthermore, by reducing the number of manned aircraft operating in the NAS, 

congestion around airports caused by arriving and departing aircraft will be reduced. The 

DJI Phantom 3 Professional UA does not require an airport to takeoff or land. Likewise, a 

reduction of manned aircraft conducting aerial video and photography missions would 

result in fewer aircraft that must be handled by air traffic control during the ground, 

takeoff, departure, arrival, and landing phases of flight operations.

2. The Public Will Benefit From The Safety And Efficiency Of The DJI 

Phantom 3 Professional UAS. 

Conducting aerial acquisitions with the DJI Phantom 3 Professional UAS, instead 

of manned aircraft, will greatly benefit the public by drastically reducing the levels of air 

and noise pollution generated during traditional aerial video and still photography flight 

operations. By using battery power and electric motors, the DJI Phantom 3 Professional

UAS produces no air pollution, and is the most viable environmentally conscious 

alternative to the cabin class, six cylinder internal combustion engine aircraft that are 

typically utilized for aerial video and photography, while burning approximately 20-30 

gallons per hour of leaded aviation fuel. The DJI Phantom 3 Professional UA, while 

reducing the carbon footprint of aerial acquisitions, also eliminates noise pollution, as the 
17

UAs are propelled by battery powered electric motors, rather than an internal combustion 

engine. 

By using the DJI Phantom 3 Professional UAS to perform aerial acquisitions, the 

substantial risk to life and property in the air and on the ground, which is usually

associated with traditional manned aircraft flight operations, will be substantially reduced 

or completely eliminated. Aside from the lack of flight crew members located onboard the 

aircraft, the DJI Phantom 3 Professional UA (weighing approximately 2 pounds 11 

ounces, at its maximum gross weight with a length of 16 inches, widths of 16 inches, and 

with no fuel on board), has less physical potential for collateral damage to life and property 

on the ground, and in the air, compared to the manned aircraft that typically conduct 

similar operations (weighing approximately 6,000 pounds with a wingspan of 

approximately 42 feet, a length of 34 feet, and a fuel capacity of 180 gallons). 

3. Performing Aerial Video and Photography Operations With The DJI 

Phantom 3 Professional UAS Will Benefit The Economy. 

In addition to being safe and efficient, the DJI Phantom 3 Professional UAS is also 

an economical alternative to using manned aircraft to conduct similar aerial operations. As 

such, operation of the DJI Phantom 3 Professional UAS will allow United States based 

companies, like Nathan Silsbee’s, to remain competitive and contribute to growth of the 

U.S. economy. Specifically, with the rising cost of aviation fuel and the Environmental 

Protection Agency (“EPA”) regulatory actions phasing out leaded aviation fuels, U.S. 

owned and operated companies must adopt new and alternative technology in order to 

remain competitive. Operating the battery powered DJI Phantom 3 Professional UASs is 

one such technology that not only allows companies greater operational flexibility
18

compared to manned aircraft, but provides such flexibility without the high operational 

cost of a traditional manned aircraft. 

By operating the DJI Phantom 3 Professional UAS, companies such as Nathan 

Silsbee’s, can remain competitive and profitable, and therefore, provide greater job 

stability to employees and contractors, which will ultimately contribute to growth of the 

U.S. economy. Improved financial performance of U.S. companies, through commercial 

use of the DJI Phantom 3 Professional UAS, provides a stable workforce that increases 

consumer spending; improves local, state, and federal tax revenues; and allows companies 

to invest in research and development in order to remain competitive both in the United 

States and abroad. 

4. There Are No Privacy Issues. 

Similar to the manned aerial acquisition flight operations that have been conducted for 

decades, Nathan Silsbee’s proposed operation of the DJI Phantom 3 Professional UAS will 

not implicate any privacy issues. Specifically, the DJI Phantom 3 Professional UAS will be 

operated only in compliance with operating documents (i.e., Monthly Maintenance Log, 

and DJI Phantom 3 Professional) which requires property owner involvement as well as 

local law enforcement notification, and in accordance with the Federal Aviation 

Regulations, including the minimum altitude requirements of 14 C.F.R. § 91.119. 

E. The Reasons Why Granting The Exemption Would Not Adversely Affect Safety, 

Or How The Exemption Would Provide A Level Of Safety At Least Equal To That 

Provided By The Rule From Which Nathan Silsbee Seeks Exemption. 

1. Reasons Why The DJI Phantom 3 Professional UA Meets The Conditions 

Of The FAA Modernization and Reform Act of 2012 (FMRA) Section 333. 

In consideration of the size, weight, speed, and limited operating area associated 

with the unmanned aircraft and its operation, Nathan Silsbee’s operation of the DJI 
19

Phantom 3 Professional UAS meets the conditions of FMRA Section 333, and will not 

require an airworthiness certificate in accordance with 14 C.F.R. Part 21, Subpart H. 

Section 333 provides authority for a UAS to operate without airworthiness 

certification and sets forth requirements for considering whether a UAS will create a 

hazard to users of the NAS or the public, or otherwise pose a threat to national security. 

Specifically, FMRA Section 333 states the following, in part: 

(a) In General.--Notwithstanding any other requirement of this subtitle, and not 

later than 180 days after the date of enactment of this Act, the Secretary of 

Transportation shall determine if certain unmanned aircraft systems may 

operate safely in the national airspace system before completion of the plan 

and rulemaking required by section 332 of this Act or the guidance required by 

section 334 of this Act. 

(b) Assessment of Unmanned Aircraft Systems.--In making the determination under 

subsection (a), the Secretary shall determine, at a minimum--

(1) which types of unmanned aircraft systems, if any, as a result of their 

size, weight, speed, operational capability, proximity to airports and 

populated areas, and operation within visual line of sight do not create 

a hazard to users of the national airspace system or the public or pose a 

threat to national security; and

(2) whether a certificate of waiver, certificate of authorization, or 

airworthiness certification under section 44704 of title 49, United States 

Code, is required for the operation of unmanned aircraft systems 

identified under paragraph (1). 

(c) Requirements for Safe Operation.--If the Secretary determines under this 

section that certain unmanned aircraft systems may operate safely in the 

national airspace system, the Secretary shall establish requirements for the safe 

operation of such aircraft systems in the national airspace system. 

In seeking this exemption, Nathan Silsbee submits that the DJI Phantom 3 

Professional UAS can operate safely in the NAS pursuant to FMRA Section 333, as 

demonstrated by: (a) the characteristics of the DJI Phantom 3 Professional UAS; (b) the 

pilot certification requirement; and (c) the specific operating limitations. 
20

a. The Specifications Of The DJI Phantom 3 Professional UAS Demonstrate 

Its Safe Characteristics.

The DJI Phantom 3 Professional UAS does not create a hazard to users of the NAS 

or the public, or otherwise pose a threat to national security considering its size, weight, 

speed, and operational capability. 

i. Technical Specifications Of The DJI Phantom 3 Professional UAS. 

The technical specifications of the DJI Phantom 3 Professional UAS is set forth by

the DJI Phantom 3 Professional Specifications and Data Sheet, attached hereto as Exhibit 

A. 

ii. The DJI Phantom 3 Professional UAS Autonomous Flight And 

Navigation Modes Enable The UASs To Remain Within A Defined 

Operational Area. 

The DJI Phantom 3 Professional UAS may be operated in both manual and fully

autonomous flight modes. A complete description of the flight and navigational modes of 

the DJI Phantom 3 Professional UAS is provided at pages 25-35 of the DJI Phantom 3 

Professional and pages 12-16 User Manual, attached hereto as Exhibit B . 

iii. The DJI Phantom 3 Professional UAS is Designed For Automatic 

Return To Home Point Or Hover In The Event Of Loss Of The 

Control Link Or Navigation. 

When the Control Link is lost, the DJI Phantom 3 Professional UA will remain 

stationary, in flight, for 3 seconds or more. If, after 3 seconds, the DJI Phantom 3 

Professional UA does not reacquire control link data from the GCS, the UAs will assume 

that the Control Link is lost and the UAs will return to the home position (i.e., failsafe 

mode) via GPS, and will descend to the takeoff position and shutdown. 
21

A complete description of the Failsafe Functions of the DJI Phantom 3 Professional

UAS are set forth at pages 27 through 29 of the DJI Phantom 3 Professional User Manual, 

attached hereto as Exhibit B. 

iv. The DJI Phantom 3 Professional GCS And Its Operation.

A complete description of the operation and specifications of the DJI Phantom 3 

Professional GCS and flight control software is provided at pages 32 through 43 of the DJI 

Phantom 3 Professional User Manual. DJI Phantom 3 Professional User Manual is

attached hereto as Exhibits B.

b. Flight Operations Of DJI Phantom 3 Professional UAS is Limited To The 

Line Of Sight Of A Certificated Pilot in Command With A Safety 

Observer. 

Nathan Silsbee will only utilize certificated pilots who possess a current and valid 

airman medical certificate to act as a pilot in command (PIC) of the DJI Phantom 3 

Professional UAS. Additionally, a safety observer will assist all pilots during flight time. 

c. Flights Of DJI Phantom 3 Professional UAS Will Be Conducted Pursuant 

To Specific Operating Limitations. 

In seeking this exemption, Nathan Silsbee proposes to commercially operate DJI 

Phantom 3 Professional UAS for the special purpose of conducting aerial video and 

photography over certain areas of United States, pursuant to the following specific 

operating limitations:

1. Operations authorized by this grant of exemption will be limited to the following 

aircraft described in the operating documents, rotorcraft UASs weighing less 

than 55 pounds maximum gross weight: DJI Phantom 3 Professional Unmanned 

Aircraft Systems. Proposed operations of any other aircraft will require a new 

petition or a petition to amend this grant. 

2. UAS operations under this exemption will be limited to conducting operations 

for the purpose of aerial video and photography. 

3. The UAs may not be flown at an indicated airspeed exceeding 20 knots.
22

4. The UA must be operated at an altitude of no more than 400 feet above ground 

level (AGL), as indicated by the procedures specified in the operating 

documents unless a special request is made and approved by ATC. All altitudes 

reported to ATC must be in feet AGL. 

5. The UA must be operated within visual line of sight (VLOS) of the PIC at all 

times. This requires the PIC to be able to use human vision unaided by any 

device other than corrective lenses, as specified on the PIC’s FAA-issued airman 

medical certificate. 

6. The use of first person view (FPV) by the PIC or safety observer (SO) is not 

permitted. 

7. All operations must utilize a safety observer (SO). The SO may be used to satisfy

the VLOS requirement as long as the PIC always maintains VLOS capability. 

The SO and PIC must be able to communicate verbally at all times. Electronic 

messaging or texting is not permitted during flight operations. The PIC must be 

designated before the flight and cannot transfer his or her designation for the 

duration of the flight. The PIC must ensure that the SO can perform the 

functions prescribed in the operating documents. 

8. The SO must not perform any other duties beyond assisting the PIC with seeing 

and avoiding other air traffic and other ground based obstacles/obstructions and 

is not permitted to operate the camera or other instruments. 

9. The operating documents and the grant of exemption must be accessible during 

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

discrepancy exists between the conditions and limitations contained in the grant 

of exemption and the procedures outlined in the operating documents, the 

conditions and limitations contained in the grant of exemption take precedence 

and must be followed. Otherwise, the operator must follow the procedures as 

outlined in its operating documents. The operator may update or revise its 

operating documents. It is the operator’s responsibility to track such revisions 

and present updated and revised documents to the Administrator upon request. 

The operator must also present updated and revised documents if it petitions for 

extension or amendment to the grant of exemption. If the operator determines 

that any update or revision would affect the basis upon which the FAA granted 

the exemption, then the operator must petition for amendment to its grant of 

exemption. The FAA’s UAS Integration Office (AFS-80) may be contacted if 

questions arise regarding updates or revisions to the operating documents. 

10. Prior to each flight the PIC must inspect the UAS to ensure that it is in a 

condition for safe flight. If the inspection reveals a condition that affects the 

safe operation of the UAS, the aircraft is prohibited from operating until the 

necessary maintenance has been performed and the UAS is found to be in a 

condition for safe flight. The Ground Control Station must be included in the 
23

preflight inspection. All maintenance and alterations must be properly 

documented in the aircraft records.

11. Any UAS 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. The PIC who conducts the 

functional test flight must make an entry in the aircraft records. 

12. The pre-flight inspection must account for all potential discrepancies, e.g. 

inoperable components, items, or equipment, not already covered in the 

relevant sections of the operating documents. 

13. The operator must follow the UAS manufacturer’s aircraft/component, 

maintenance, overhaul, replacement, inspection, and life limit requirements. 

14. The operator must carry out its maintenance, inspections, and record keeping 

requirements, in accordance with the operating documents. Maintenance, 

inspection, alterations, and status of replacement/overhaul component parts 

must be noted in the aircraft records, including total time in service, description 

of work accomplished, and the signature of the authorized person returning the 

UAS to service. 

15. Each UAS operated under this exemption must comply with all manufacturer 

Safety Bulletins. 

16. The authorized person must make an entry in the aircraft record of the 

corrective action taken against discrepancies discovered between inspections. 

17. The PIC must possess at least a private pilot certificate and at least a current 

third- class medical certificate. 

18. The operator may not permit any PIC to operate unless the PIC 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 the 

exemption, including evasive and emergency maneuvers and maintaining 

appropriate distances from persons, vessels, vehicles and structures. PIC 

qualification flight hours must be logged in a manner consistent with 14 C.F.R. 

§ 61.51(b). Flights for the purposes of training the operator’s PICs are 

permitted under the terms of the 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 PIC must operate the UA 

with appropriate distance from nonparticipants in accordance with 14 C.F.R. § 

91.119. 

19. UAS 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 

(VMC). If flight at night is required, a special request will be made at the FAA 
24

office closest to proposed area of operations. Flights under special visual flight 

rules (SVFR) are not authorized. 

20. The UA may not operate within 5 nautical miles of an airport reference point as 

denoted on a current FAA-published aeronautical chart unless a letter of

agreement with that airport’s management is obtained, and the operation is 

conducted in accordance with a NOTAM as required by the operator’s COA.

The letter of agreement with the airport management must be made available to 

the Administrator upon request. 

21. The UA 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 

PIC. 

22. If the UA loses communications or loses its GPS signal, it must return to a predetermined location within the planned operating area and land or be recovered 

in accordance with the operating documents. 

23. The PIC must abort the flight in the event of unpredicted obstacles or 

emergencies in accordance with the operating documents. 

24. The PIC is prohibited from beginning a flight unless (considering wind and 

forecast weather conditions) there is enough power to fly at normal cruising 

speed to the intended landing point and land the UA with 25% battery power 

remaining. 

25. The operator must obtain an Air Traffic Organization (ATO) issued Certificate 

of Waiver or Authorization (COA) prior to conducting any operations under the 

grant of exemption. This COA will also require the operator to request a Notice 

to Airman (NOTAM) not more than 72 hours in advance, but not less than 48 

hours prior to the operation. All operations shall be conducted in accordance 

with airspace requirements in the ATO issued COA including class of airspace, 

altitude level and potential transponder requirements. 

26. All aircraft operated in accordance with the exemption must be identified by

serial number, registered in accordance with 14 C.F.R. part 47, and have 

identification (N- Number) markings in accordance with 14 C.F.R. part 45, 

Subpart C. Markings must be as large as practicable. 

27. Before conducting operations, the radio frequency spectrum used for operation 

and control of the UA must comply with the Federal Communications 

Commission (FCC) or other appropriate government oversight agency

requirements. 

28. The documents required fewer than 14 C.F.R. 91.9 and 91.203 must be 

available to the PIC at the Ground Control Station of the UAS any time the 

UAS is operating. These documents must be made available to the 

Administrator or any law enforcement official upon request. 
25

29. The UA must remain clear and yield the right of way to all manned aviation 

operations and activities at all times. 

30. The UAS may not be operated by the PIC from any moving device or vehicle.

31. Flight operations must be conducted at least 500 feet from all nonparticipating 

persons (persons other than the PIC, SO, operator trainees or essential persons), 

vessels, vehicles, and structures unless: 

a. Barriers or structures are present that sufficiently protect nonparticipating 

persons from the UA and/or debris in the event of an accident. The 

operator must ensure that nonparticipating persons remain under such 

protection. If a situation arises where nonparticipating persons leave such 

protection and are within 500 feet of the UA, flight operations must cease 

immediately and/or; 

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

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

permission and 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, and; 

c. Operations nearer to the PIC, SO, operator trainees or essential persons 

do not present an undue hazard to those persons per § 91.119(a). 

32. All operations shall be conducted over private or controlled-access property

with permission from the land owner/controller or authorized representative. 

Permission from land owner/controller or authorized representative will be 

obtained for each flight to be conducted.

33. 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 UAS 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. 

2. Reasons Why An Exemption From The Requirements Of Section 61.113(a) 

And (b) Would Not Adversely Affect Safety.

Nathan Silsbee submits that the equivalent level of safety established by Section 

61.113(a) and (b) will be maintained because no PIC will be allowed to operate the DJI 

Phantom 3 Professional UAS unless that PIC has demonstrated, by meeting minimum 

flight-hour and currency requirements, that the PIC is able to safely operate the DJI 
26

Phantom 3 Professional UAS in a manner consistent with the exemption, including evasive 

and emergency maneuvers and maintaining appropriate distances from people, vessels, 

vehicles and structures. 

Considering Nathan Silsbee’s proposed area of operations, and the operating 

limitations set forth-above; the parallel nature of private pilot aeronautical knowledge 

requirements to those of commercial pilot requirements (See Exemption No. 11062); and 

the airmanship skills necessary to safely operate the DJI Phantom 3 Professional UAS, 

Nathan Silsbee submits that the additional manned airmanship experience of a 

commercially certificated pilot would not correlate to the airmanship skills necessary for 

Nathan Silsbee’s specific proposed flight operations. 

The FAA has previously granted relief from Section 61.113(a) and (b) specific to 

UAS, in circumstances similar, in all material respects, to those presented herein (e.g. 

Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 

11136, 11138, 11150, 11153, 11156, 11158, 11159, 11160, 11161). 

Nathan Silsbee will not allow any PIC to operate the DJI Phantom 3 Professional

UAS unless that PIC has demonstrated, by meeting minimum flight-hour requirements or 

the DJI Phantom 3 Professional UAS training and currency requirements, that the PIC is 

able to safely operate the DJI Phantom 3 Professional UAS in a manner consistent with 

this exemption, including evasive and emergency maneuvers and maintaining appropriate 

distances from people, vessels, vehicles and structures. 

Specifically, the PIC must have accumulated and logged, in a manner consistent 

with 14 C.F.R. § 61.51(b), 25 hours of total time as a UAS rotorcraft pilot (with a 

minimum of 5 hours of those hours as a UAS pilot operating the same make and model of 
27

UAS to be used for operations under the exemption). In addition to the hour requirements, 

the PIC must accomplish 3 takeoffs and landings in the preceding 90 days (for currency

purposes). 

As in Exemption Nos. 11062, 11138, and 11153, prior documented flight 

experience that was obtained in compliance with applicable regulations will ensure an 

equivalent level of safety during Nathan Silsbee’s proposed operations. The Administrator 

has held that prior documented flight experience that was obtained in compliance with 

applicable regulations would ensure safe operations, stating as follows: 

In Exemption No. 11062, the FAA required that prior to conducting operations for 

the purpose of motion picture filming (or similar operations), the PIC must have 

accumulated and logged, in a manner consistent with 14 CFR 61.51(b), 25 hours of 

total time as a UAS rotorcraft pilot including at least 10 hours logged as a UAS 

pilot with a multi-rotor UAS. Prior to operations under Exemption No. 11062, the 

PIC must also have accumulated and logged a minimum of 5 hours as a UAS pilot 

operating the same make and model of UAS to be used for operations under the 

exemption. For clarification, the FAA considers these minimum hour requirements 

to be inclusive rather than additive; i.e. 5 hours make and model time may be 

included in the 10 hours of multi-rotor time and the 10 hours may be included in 

the total 25 hours of UAS rotorcraft time. In addition to the hour requirements, the 

PIC must accomplish 3 takeoffs and landings in the preceding 90 days (for 

currency purposes). The FAA finds that at a minimum, the flight-hour requirements 

in Exemption No. 11062 are appropriate to practice and build proficiency in the 

skills necessary to safely conduct the petitioner’s proposed operations. The FAA 

also finds that prior documented flight experience that was obtained in compliance 

with applicable regulations would satisfy this requirement. Training, proficiency, 

and experience-building flights can also be conducted under the grant of exemption 

to accomplish the required flight time. During training, proficiency, and 

experience-building flights the PIC is required to operate the UA with appropriate 

distances in accordance with 14 C.F.R 91.119. 

Exemption No. 11138 at page 15. 

Accordingly, Nathan Silsbee will ensure safe operations by not allowing any PIC to 

operate the DJI Phantom 3 Professional UAS unless that PIC has demonstrated, by

meeting minimum flight-hour and currency requirements, that the PIC is able to safely 

operate the DJI Phantom 3 Professional UAS in a manner consistent with the exemption, 
28

including evasive and emergency maneuvers and maintaining appropriate distances from 

people, vessels, vehicles and structures. 

3. Reasons Why An Exemption From The Requirements Of Section 91.7(a) 

Would Not Adversely Affect Safety. 

The equivalent level of safety established by Section 91.7(a) will be maintained 

because prior to every flight, Nathan Silsbee will ensure that the DJI Phantom 3 

Professional UAS is in an airworthy condition based upon the UAS’s compliance with its 

operating documents and as stated in the conditions and limitations herein. 

Additionally, the FAA has previously granted relief from Section 91.7(a) specific 

to UAS, in circumstances similar, in all material respects, to those presented herein (e.g. 

Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11110, 11112, 

11136, 11138, 11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161). 

4. Reasons Why An Exemption From The Requirements Of Section 91.121 

Would Not Adversely Affect Safety.

The equivalent level of safety established by Section 91.121 will be maintained 

because the altitude information of the DJI Phantom 3 Professional UA will be provided to 

the PIC via GPS equipment and a radio communications telemetry data link, which 

downlinks from the UA to the GCS for active monitoring of the flight path and altitude. 

This altitude information, combined with Nathan Silsbee’s operation of the DJI Phantom 3 

Professional UA within visual line of sight, at or below 400 feet AGL, will ensure a level 

of safety equivalent to Section 91.121. The altitude information will be generated by GPS 

equipment installed onboard the aircraft. Prior to each flight, a zero altitude initiation point 

is automatically established by the UASs at ground level. 

The FAA has previously granted relief from Section 91.121 specific to UAS, in 

circumstances similar, in all material respects, to those presented herein (e.g. Exemption 
29

Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11112, 11136, 11138, 

11150, 11153, 11156, 11157, 11158, 11159, 11160, 11161). 

5. Reasons Why An Exemption From The Requirements Of Section 91.151(b) 

Would Not Adversely Affect Safety.

A grant of this exemption would ensure an equivalent level of safety established by

14 C.F.R. Section 91.151(b) as a result of (1) the technical specifications of the DJI 

Phantom 3 Professional UAS; (2) the limitations on the proposed flight operations; and (3) 

the location of the proposed flight operations. Accordingly, Nathan Silsbee will ensure that 

it will safely operate the battery powered DJI Phantom 3 Professional UA during daylight 

hours in VFR conditions, with enough battery power to fly for a total duration of 13.5 

minutes to the first point of intended landing and, assuming normal cruising speed, to fly 

after that for at least 4.5 minutes. 

Here, as in Exemption No. 11109, the technical specifications of the DJI Phantom 3 

Professional UAS; the limitations on the proposed flight operations; and the location of the 

proposed operations, will ensure an equivalent level of safety established by 14 C.F.R. 

Section 91.151(b). Furthermore, safety will be ensured as the DJI Phantom 3 Professional

UAS provide audible and visual warnings to the PIC at the GCS when the UAs 

experiences low battery voltage, the first warning occurring at approximately 33% 

remaining battery power, and again at approximately 10% remaining battery power. At the 

critically low battery level, the DJI Phantom Vision+ UAS will descend and land 

automatically. 

Significantly, previous exemptions granted by the FAA concerning Section 91.151 

establish that safety is not adversely affected when the technical characteristics and 

operating limitations of the UAS are considered. Relief has been granted for manned 
30

aircraft to operate at less than the minimums prescribed in Section 91.151, including 

Exemption Nos. 2689, 5745, and 10650. Moreover, the FAA has previously granted relief 

from Section 91.151 specific to UAS, in circumstances similar, in all material respects, to 

those presented herein (e.g. Exemption Nos. 8811, 10808, 10673, 11042, 11062, 11063, 

11064, 11065, 11066, 11067, 11080, 11109, 11110, 11136, 11138, 11150, 11153, 11156, 

11157, 11158, 11159, 11160, 11161). 

6. Reasons Why An Exemption From The Requirements Of Sections

91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), And 91.417(a) & (b) Would 

Not Adversely Affect Safety. 

In seeking this exemption, Nathan Silsbee submits that the equivalent level of 

safety with regard to the regulatory maintenance and alteration requirements established by 

Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) will be met 

because Nathan Silsbee will use trained technicians to perform maintenance, alterations, or 

preventive maintenance on the UAS using the methods, techniques, and practices 

prescribed in the operating documents (i.e., Monthly Maintenance Log, and DJI Phantom 3 

Professional Instruction Manual). Furthermore, Nathan Silsbee will document and 

maintain all maintenance records for the DJI Phantom 3 Professional UAS. 

Since the DJI Phantom 3 Professional UAS will be inspected as prescribed by the 

operating documents, Nathan Silsbee will maintain the equivalent level of safety 

established by Sections 91.405(a), 91.409(a)(1), and 91.409(a)(2). A copy of the DJI 

Phantom 3 Professional User Manual is attached hereto as Exhibit B; a copy of the DJI 

Phantom 3 Professional UAS Maintenance LOG is attached hereto as Exhibit C. 

Likewise, the exemption sought will not adversely affect safety because Nathan 

Silsbee will use trained technicians to perform maintenance, alterations or preventive 
31

maintenance on the UAS using the methods, techniques, and practices prescribed by the 

operating documents. 

Furthermore, the exemption sought would maintain an equivalent level of safety 

established by Sections 91.407, 91.417(a) and 91.417(b), because all maintenance of the 

DJI Phantom 3 Professional UAS will be performed by trained technicians. Maintenance 

will be documented and maintained utilizing the monthly maintenance log. 

Significantly, previous exemptions granted by the FAA concerning Sections 

91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b) establish that safety is 

not adversely affected when the technical characteristics and operating limitations of the 

UAS are considered. 

In consideration of Nathan Silsbee’s proposed operating limitations, the operating 

documents, and the technical aspects of the DJI Phantom 3 Professional UAS, Nathan 

Silsbee submits that safety will not be adversely affected by granting exemption from 14 

C.F.R. Sections 91.405(a), 91.407(a)(1) and (a)(2), 91.409(a)(2), and 91.417(a) and (b). 

The FAA has previously granted relief specific to UAS in circumstances similar, in all 

material respects, to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 

11065, 11066, 11067, 11080, 11109, 11110, 11112, 11136, 11138, 11150, 11153, 11156, 

11157, 11158, 11159, 11160, 11161). 

7. The FAA May Prescribe Any Other Conditions For Safe Operation. 

In accordance with Section 333 of the FAA Modernization and Reform Act of 2012 

(FMRA) and 14 C.F.R. § 21.16 entitled Special Conditions, Nathan Silsbee requests that 

the FAA prescribe special conditions for the intended operation of the DJI Phantom 3 

Professional UAS, which contain such safety standards that the Administrator finds 
32

necessary to establish a level of safety equivalent to that established by 14 C.F.R. Part 21, 

Subpart H, and 14 C.F.R §§ 61.113(a) & (b), 91.7 (a), 91.121, 91.151(b), 91.405(a), 

91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b). Such special conditions will 

permit safe operation of the UAs for the limited purpose of conducting aerial video and

photography over certain areas of the United States for compensation or hire. FMRA 

Section 333 sets forth the requirements for considering whether a UAS will create a hazard 

to users of the NAS or the public, or otherwise pose a threat to national security; and 

further, provides the authority for such UAS to operate without airworthiness certification 

in accordance with any requirements that must be established for the safe operation of the 

UAS in the NAS. 

Likewise, the Administrator may prescribe special conditions pursuant to 14 C.F.R.

§ 21.16, for operation of the DJI Phantom 3 Professional UAS, since the airworthiness 

regulations of 14 C.F.R. Part 21 do not contain adequate or appropriate safety standards, 

due to the novel or unusual design features of the aircraft. Section 21.16, entitled Special 

Conditions, states the following: 

If the FAA finds that the airworthiness regulations of this subchapter do not contain 

adequate or appropriate safety standards for an aircraft, aircraft engine, or propeller 

because of a novel or unusual design feature of the aircraft, aircraft engine or 

propeller, he prescribes special conditions and amendments thereto for the product. 

The special conditions are issued in accordance with Part 11 of this chapter and 

contain such safety standards for the aircraft, aircraft engine or propeller as the 

FAA finds necessary to establish a level of safety equivalent to that established in 

the regulations. 

See 14 C.F.R. § 21.16.

Therefore, in accordance with FMRA Section 333 and 14 C.F.R. § 21.16, the FAA 

may prescribe special conditions for Leading Edge’s intended operation of the DJI 

Phantom 3 Professional UAS, which contain such safety standards that the Administrator 
33

finds necessary to establish a level of safety equivalent to that established by 14 C.F.R. 

Part 21, Subpart H, and 14 C.F.R Sections 61.113(a) & (b), 91.7(a), 91.121, 91.151(b), 

91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), and 91.417(a) & (b).

F. A Summary That Can Be Published In The Federal Register, stating: The Rules

DJI PHANTOM 3 PROFESSIONAL TECHNICAL SPECIFICATIONS

Nathan Silsbee only utilizes safe and reliable UASs. DJI is an industry leader in small 

UAS production. DJI UASs are loaded with ground breaking software enabling the user to 

set parameters which will not allow flight into controlled airspace. Parameters can also be 

set to limit flight to no higher than a predetermined and set altitude as well as limit flight to 

a predetermined and set distance. In addition, DJI software provides real-time altitude and 

location information to the PIC via the linked monitor (smart phone/tablet devices)
