Exemption No. 12249

Regulatory Docket No. FAA–2015–2028

Mr. Jordan Keeney

Consulting Services Incorporated LLC

858 Contract Street

Lexington, KY 40505

Dear Mr. Keeney:

This letter is to inform you that we have granted your request for exemption. It transmits our 

decision, explains its basis, and gives you the conditions and limitations of the exemption, 

including the date it ends.

By letter dated May 15, 2015, you petitioned the Federal Aviation Administration (FAA) on 

behalf of Consulting Services Inc. LLC (hereinafter petitioner or operator) for an exemption. 

The petitioner requested to operate an unmanned aircraft system (UAS) to conduct aerial 

imaging and videography.

See Appendix A for the petition submitted to the FAA describing the proposed operations and 

the regulations that the petitioner seeks an exemption.

The FAA has determined that good cause exists for not publishing a summary of the petition 

in the Federal Register because the requested exemption would not set a precedent, and any 

delay in acting on this petition would be detrimental to the petitioner.

Airworthiness Certification

The UAS proposed by the petitioner are the DJI Phantom 2 Vision+, DJI Phantom 3 Vision,

and DJI Inspire 1.

The petitioner requested relief from 14 CFR part 21, Certification procedures for products 

and parts, Subpart H—Airworthiness Certificates. In accordance with the statutory criteria 

provided in Section 333 of Public Law 112−95 in reference to 49 U.S.C. § 44704, and in 
2

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

aircraft and its operation, the Secretary of Transportation has determined that this aircraft 

meets the conditions of Section 333. Therefore, the FAA finds that the requested relief from 

14 CFR part 21, Certification procedures for products and parts, Subpart H—Airworthiness 

Certificates, and any associated noise certification and testing requirements of part 36, is 

not necessary.

The Basis for Our Decision

You have requested to use a UAS for aerial data collection1. The FAA has issued grants of 

exemption in circumstances similar in all material respects to those presented in your petition. 

In Grants of Exemption Nos. 11062 to Astraeus Aerial (see Docket No. FAA−2014−0352), 

11109 to Clayco, Inc. (see Docket No. FAA−2014−0507), 11112 to VDOS Global, LLC (see

Docket No. FAA−2014−0382), and 11213 to Aeryon Labs, Inc. (see Docket No. 

FAA−2014−0642), the FAA found that the enhanced safety achieved using an unmanned 

aircraft (UA) with the specifications described by the petitioner and carrying no passengers or 

crew, rather than a manned aircraft of significantly greater proportions, carrying crew in 

addition to flammable fuel, gives the FAA good cause to find that the UAS operation enabled 

by this exemption is in the public interest.

Having reviewed your reasons for requesting an exemption, I find that—

 They are similar in all material respects to relief previously requested in Grant of 

Exemption Nos. 11062, 11109, 11112, and 11213;

 The reasons stated by the FAA for granting Exemption Nos. 11062, 11109, 11112, and 

11213 also apply to the situation you present; and 

 A grant of exemption is in the public interest.

Our Decision

In consideration of the foregoing, I find that a grant of exemption is in the public interest. 

Therefore, pursuant to the authority contained in 49 U.S.C. 106(f), 40113, and 44701, 

delegated to me by the Administrator, Consulting Services Inc. LLC is granted an exemption 

from 14 CFR §§ 61.23(a) and (c), 61.101(e)(4) and (5), 61.113(a), 61.315(a), 91.7(a), 

91.119(c), 91.121, 91.151(a)(1), 91.405(a), 91.407(a)(1), 91.409(a)(1) and (2), and 91.417(a) 

and (b), to the extent necessary to allow the petitioner to operate a UAS to perform aerial data 

collection. This exemption is subject to the conditions and limitations listed below.

 

1 Aerial data collection includes any remote sensing and measuring by an instrument(s) aboard the UA. 

Examples include imagery (photography, video, infrared, etc.), electronic measurement (precision surveying, RF 

analysis, etc.), chemical measurement (particulate measurement, etc.), or any other gathering of data by 

instruments aboard the UA.

Conditions and Limitations

In this grant of exemption, Consulting Services Inc. LLC is hereafter referred to as 

the operator.

Failure to comply with any of the conditions and limitations of this grant of exemption will be 

grounds for the immediate suspension or rescission of this exemption.

1. Operations authorized by this grant of exemption are limited to the DJI Phantom 2 

Vision+, DJI Phantom 3 Vision, and DJI Inspire 1when weighing less than 55 pounds 

including payload. Proposed operations of any other aircraft will require a new 

petition or a petition to amend this exemption.

2. Operations for the purpose of closed-set motion picture and television filming are 

not permitted. 

3. The UA may not be operated at a speed exceeding 87 knots (100 miles per hour). The 

exemption holder may use either groundspeed or calibrated airspeed to determine 

compliance with the 87 knot speed restriction. In no case will the UA be operated at 

airspeeds greater than the maximum UA operating airspeed recommended by the 

aircraft manufacturer.

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

(AGL). Altitude must be reported 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 or 

U.S. driver’s license.

6. All operations must utilize a visual observer (VO). The UA must be operated within 

the visual line of sight (VLOS) of the PIC and VO at all times. The VO may be used 

to satisfy the VLOS requirement as long as the PIC always maintains VLOS 

capability. The VO 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 VO can perform the duties 

required of the VO.

7. This exemption and all documents needed to operate the UAS and conduct its 

operations in accordance with the conditions and limitations stated in this grant of 

exemption, are hereinafter referred to as the operating documents. The operating 

documents must be accessible during UAS operations and made available to the 

Administrator upon request. If a discrepancy exists between the conditions and 
4

limitations in this exemption and the procedures outlined in the operating documents, 

the conditions and limitations herein 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 or any law enforcement official upon request. The 

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

or amendment to this grant of exemption. If the operator determines that any update 

or revision would affect the basis upon which the FAA granted this exemption, then 

the operator must petition for an 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.

8. 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 prior to conducting further operations under this exemption. 

Functional test flights may only be conducted by a PIC with a VO and must remain at 

least 500 feet from other people. The functional test flight must be conducted in such 

a manner so as to not pose an undue hazard to persons and property.

9. The operator is responsible for maintaining and inspecting the UAS to ensure that it is 

in a condition for safe operation.

10. Prior to each flight, the PIC must conduct a pre-flight inspection and determine the 

UAS is in a condition for safe flight. The pre-flight inspection must account for all 

potential discrepancies, e.g., inoperable components, items, or equipment. 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.

11. The operator must follow the UAS manufacturer’s maintenance, overhaul, 

replacement, inspection, and life limit requirements for the aircraft and 

aircraft components.

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

safety bulletins.

13. Under this grant of exemption, a PIC must hold either an airline transport, 

commercial, private, recreational, or sport pilot certificate. The PIC must 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 must 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.
5

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

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

operated under this exemption, including evasive and emergency maneuvers and 

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

qualification flight hours and currency must be logged in a manner consistent with 

14 CFR § 61.51(b). Flights for the purposes of training the operator’s PICs and VOs 

(training, proficiency, and experience-building) and determining the PIC’s ability to 

safely operate the UAS in a manner consistent with how the UAS will be operated 

under this exemption are permitted under the terms of this exemption. However, 

training operations may only be conducted during dedicated training sessions. During 

training, proficiency, and experience-building flights, all persons not essential for 

flight operations are considered nonparticipants, and the PIC must operate the UA 

with appropriate distance from nonparticipants in accordance with 14 CFR § 91.119.

15. UAS operations may not be conducted during night, as defined in 14 CFR § 1.1. All 

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

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

16. The UA may not operate within 5 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 the exemption 

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

to the Administrator or any law enforcement official upon request.

17. 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.

18. If the UAS loses communications or loses its GPS signal, the UA must return to a 

pre-determined location within the private or controlled-access property.

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

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

weather conditions) there is enough available power for the UA 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.

21. Air Traffic Organization (ATO) Certificate of Waiver or Authorization (COA). All 

operations shall be conducted in accordance with an ATO-issued COA. The 

exemption holder may apply for a new or amended COA if it intends to conduct 

operations that cannot be conducted under the terms of the attached COA.
6

22. All aircraft operated in accordance with this exemption must be identified by serial 

number, registered in accordance with 14 CFR part 47, and have identification 

(N−Number) markings in accordance with 14 CFR part 45, Subpart C. Markings must 

be as large as practicable.

23. Documents used by the operator to ensure the safe operation and flight of the UAS and 

any documents required under 14 CFR §§ 91.9 and 91.203 must be available to the 

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

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

official upon request.

24. The UA must remain clear and give way to all manned aviation operations and 

activities at all times. 

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

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

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 in a manner ensuring the safety 

of nonparticipating persons; and

b. The owner/controller of any vessels, vehicles or structures has granted permission 

for operating closer to those objects 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.

The PIC, VO, operator trainees or essential persons are not considered 

nonparticipating persons under this exemption.

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

permission from the property owner/controller or authorized representative. 

Permission from property owner/controller or authorized representative will be 

obtained for each flight to be conducted.

28. 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.

If this exemption permits operations for the purpose of closed-set motion picture and 

television filming and production, the following additional conditions and limitations apply.

29. The operator must have a motion picture and television operations manual (MPTOM) 

as documented in this grant of exemption.

30. At least 3 days before aerial filming, the operator of the UAS affected by this 

exemption must submit a written Plan of Activities to the local Flight Standards 

District Office (FSDO) with jurisdiction over the area of proposed filming. The 3-day 

notification may be waived with the concurrence of the FSDO. The plan of activities 

must include at least the following:

a. Dates and times for all flights;

b. Name and phone number of the operator for the UAS aerial filming conducted 

under this grant of exemption;

c. Name and phone number of the person responsible for the on-scene operation of 

the UAS;

d. Make, model, and serial or N−Number of UAS to be used;

e. Name and certificate number of UAS PICs involved in the aerial filming;

f. A statement that the operator has obtained permission from property owners 

and/or local officials to conduct the filming production event; the list of those 

who gave permission must be made available to the inspector upon request;

g. Signature of exemption holder or representative; and

h. A description of the flight activity, including maps or diagrams of any area, city, 

town, county, and/or state over which filming will be conducted and the altitudes 

essential to accomplish the operation.

31. Flight operations may be conducted closer than 500 feet from participating persons 

consenting to be involved and necessary for the filming production, as specified in the

Re: Petition of Consulting Services Incorporated of Kentucky (CSI) for an Exemption Pursuant to 

Section 333 of the FAA Modernization and Reform Act of 2012 to Operate an Unmanned Aircraft

System

Dear Sir or Madam:

Pursuant to Section 333 of the FAA Modernization and Reform Act of 2012 and 14 C.F.R. Part 11, 

Consulting Services Inc. LLC, hereafter referred to as "CSI", would like to apply for an exemption 

from the following Code of Federal Regulations (C.F.R) to be allowed commercial operation of 

lightweight Unmanned Aircraft Systems (UAS) for aerial imaging and video in the immediate and 

surrounding areas of Lexington, Kentucky.

The UAS: DJI Phantom and DJI Inspire 1

The requested exemption will permit the operation of small, unmanned 

multirotor aircraft, namely the DJI Phantom 2 Vision+, DJI Phantom 3 

Professional/Advanced, and the DJI Inspire 1. Users all over the world have 

proven these UAS’s effective and safe and DJI also continues to develop 

software and hardware to increase the safety of flying UAS’s.

These systems are produced completely assembled and ready to fly straight 

from DJI. CSI plans to not make any modifications to the UAS except for the 

addition of OEM propeller guards for enhanced safety purposes.

The four main characteristics of the Vision series UASs by DJI are:

1. Very Light Weight

The Vision series by DJI are light enough so that the operator can launch them 

by hand and land them on most surfaces without requiring a parachute or 

landing net. The low potential energy of the UAS also reduces the risk of 

hazardous situations in case that a emergency landing is necessary. The rotor 

arms of the Vision series UAS are rounded with no sharp edges and we will also 

be utilizing DJI’s recommended propeller guard system to increase the safety of 

our personnel when launching and landing the UAS. 

2. Electric Powered

The Vision series UAS by DJI are electric powered and employ removable smart 

batteries. The “Intelligent Flight Battery” developed by DJI is a LiPo 4S battery 

that is capable of producing a flight time of up to 23 minutes. This flight time 

would allow us to complete our flight plans with ease and without the worry of 

our batteries running out of charge. 

If our batteries do get low during a flight, the intelligent flight battery will 

warn us by a series of beeps and on screen notifications so that we will have 

ample time to find a safe area to land the UAS.

3. Semi-Automatic Flight 

The artificial intelligence incorporated within the Vision series UASs 

continuously analyzes data from the Initial Measurement Unit, the onboard 

GPS, and the newly available (Phantom 3 Vision models only) visioning 

positioning system. These systems allow for the user to focus more on the data 

that they are trying to capture and less on the actual flying of the drone. 

The new visioning positioning system uses visual and ultrasonic sensors to scan 

the ground beneath the Phantom 3 for patterns, enabling it to identify it’s 

position and move accurately while avoiding obstacles automatically.

FAA Section 333 Exemption Request May 15, 2015

 1 of 12
4. Enhanced Autopilot Functionality

a. Auto-Takeoff

With one tap within the DJI Pilot application, the Phantom 3 will turn on 

its motors and rise to a pre-set height. It will then hover perfectly in 

place until our personnel directs it where to go.

b. Auto-Return Home

When GPS is available, the Phantom 3 remembers the exact spot that it 

took off from. Whenever the aircraft is flying, our personnel can tap a 

button within the DJI Pilot application to have it return to the place that 

it took off from.

c. Failsafe

If the Intelligent Flight Battery is running low, or if the Phantom 3 loses 

the connection with the remote controller for any reason, the aircraft 

will automatically return to the takeoff point and land safely.

Flight Applications

The UAS will be flown in airspace under 400ft above ground level. CSI will only 

fly the UAS under controlled conditions on restricted, rural, or private 

property. The UAS will be used to monitor geotechnical situations like active 

landslides, waste landfills, coal ash landfills, construction-related studies, and 

karst topography. 

1. Landslides

CSI proposes exemption under Section 333 to operate commercially in public 

and private secured-entry landslide investigation sites. These landslides can be 

either currently active or have already failed. In either case, traversing the 

terrain physically can be dangerous to our staff and engineering personnel. By 

utilizing the high definition camera on the DJI Vision UASs the staff at CSI 

engineering can gain new perspectives of landslides from safe areas, while still 

in the line of site of the UAS. 

The benefit of not putting our personnel on the failure surface can greatly 

enhance our ability to analyze landslides while at the same time increase the 

safety of our employees. 

2. Karst Topography

CSI proposes to use UAS’s to capture digital images of karst areas. From these 

images CSI will be able to better locate areas that could potentially be sink 

holes quickly and safely.

FAA Section 333 Exemption Request May 15, 2015

 2 of 12
Regulations for which Exemption is Requested

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

14 C.F.R. §91.203 (a) (1) Subpart H, entitled Airworthiness Certificates, 

establishes the procedural requirements for the issuance of airworthiness 

certificates as required by FAR §91.203 (a) (1). Given the size and limited 

operating area associated UAS’s, an exemption from Part 21 Subpart H meets 

the requirements of an equivalent level of safety under Part 11 and §333 of the 

Reform Act. The Federal Aviation Act (49 U.S.C.§44701 (f)) and §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 

particular UAS. In all cases, an analysis of these criteria demonstrates that the 

UAS operated without an airworthiness certificate, in the restricted 

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

safer, than a conventional aircraft (fixed wing or rotorcraft) operating with an 

airworthiness certificate and without the restrictions and conditions proposed.

The UAS’s to be operated by CSI are less than 5lbs. at maximal payload 

capacity that consists of remote sensing instrumentation. The UAS will not 

carry any persons, explosives or flammable materials including combustible 

fuels, and the UAS will operate exclusively within a secured area. Unlike other 

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

monitored by both the pilot (PIC) and the Spotter. These enhancements to 

current safety practices and regulations, which already apply to civil aircraft, 

provide a greater degree of safety to the public and property owners than 

conventional aircraft operations conducted with airworthiness certificates 

issued under 14 C.P.R. Part 21, Subpart H. Lastly, application of these same 

criteria demonstrates that there is no intrinsic credible threat to national 

security posed by the UAS, due to its size, speed of operation, location of 

operation, lack of explosive materials or flammable liquid fuels, and inability 

to carry a substantial external load.

14 C.P.R. §45.23 (b). Marking of the Aircraft 

The regulation requires: When marks include only the Roman capital letter "N" 

and the registration number is displayed on limited, restricted or light-sport 

category aircraft or experimental or provisionally certificated aircraft, the 

operator must also display on that aircraft near each entrance to the cabin, 

cockpit, or pilot station, in letters not less than 2 inches nor more than 6 

inches high, the words "limited;' "restricted;' "light-sport:' "experimental:' or 

"provisional;' as applicable. Even though the UAS will have no airworthiness 

certificate, an exemption may be needed as the UAS will have no entrance to 

the cabin, cockpit or pilot station on which the word "Experimental" can be 

FAA Section 333 Exemption Request May 15, 2015

 3 of 12
placed. Given the size of the UAS, two- inch lettering will be impossible. CSI 

understands the need for markings and will mark our UAS in the largest possible 

lettering by placing the word “Experimental” or assigned number or name 

(based on a request or ruling by the FAA) on its fuselage as required by 

§45.29(f) so that anyone assisting the spotter will see the markings. Further 

markings include the use of flashing green & red LED illumination on the 

underside of the UAS frame, which adds contrast against a blue or white sky.

14 C.P.R. §61.113 (a) & (b): Private Pilot Privileges and Limitations: Pilot in 

Command (PIC) 

§61.113 (a) & (b) limit private pilots to non-commercial operations. Because 

the UAS will not carry a pilot or passengers, the proposed operations can 

achieve the equivalent level of safety of current operations by requiring a 

ground crew member to have a private pilot's license rather than a commercial 

pilot's license to operate this UAS. Unlike a conventional aircraft that carries 

the pilot and passengers, the UAS is remotely controlled with no persons on 

board. The area of operation is controlled and restricted, and all flights are 

planned and coordinated in advance. The risks associated with the operation of 

the UAS are so diminished from the level of risk associated with commercial 

operations contemplated by Part 61 when drafted, that allowing operations as 

requested with a private pilot in the ground crew exceeds the present level of 

safety achieved by 14 C.P.R. §61.113 (a) & (b). CSI’s staff professionals have 

experience flying numerous practice flights in remote areas as a hobbyist 

simulating flights to increase the experience and skills needed for flying a UAS. 

CSI also owns and practice on a computerized simulated flight software to 

increase skill levels and gain knowledge of how to maneuver the UAS safely at 

all times.

14 C.P.R. §91.7(a): Civil Aircraft Airworthiness

The regulation requires that no person may operate a civil aircraft unless it is 

in airworthy condition. As there will be no airworthiness certificate issued for 

the aircraft, should this exemption be granted, no FAA regulatory standard will 

exist for determining airworthiness. Given the size of the aircraft and the 

requirements contained in the Manual for maintenance and use of safety 

checklists prior to each flight, which are provided in the appendix, an 

equivalent level of safety will be provided.

14 C.P.R. §91.9 (b) (2): Civil Aircraft Flight Manual in the Aircraft. 

§91.9 (b) (2) provides: No person may operate a U.S. -registered civil 

aircraft ... (2) For which an Airplane or Rotorcraft Flight Manual is not required 

by §21.5 of this chapter, unless there is available in the aircraft a current 

approved airplane or Rotorcraft Flight Manual, approved manual material, 

markings, and placards, or any combination thereof. The UAS, given its size and 

configuration has no ability to carry a physical flight manual on the aircraft. 

The equivalent level of safety will be maintained by keeping the flight manual 

at the ground control point where the pilot flying the UAS will have immediate 

access to it. The FAA has issued the following exemptions to this regulation:

10602, 32827, and 10700.

14 C.P.R. §91.1 03: Preflight Action 

This regulation requires each Pilot in Command (PIC) to take certain actions 

before flight to insure the safety of flight. As FAA approved rotorcraft flight 

manuals will not be provided for the aircraft an exemption will be needed. The 

PIC will take all actions including reviewing weather, flight battery 

requirements, landing and takeoff distances and aircraft performance data 

before initiation of flight. Further, CSI will employ manufacturer (DJI) preflight 

recommendations to guarantee that best practices are implemented.

DJI has implemented Firmware updates that limit flight around airports, along 

with distance and elevation limits

14 C.P.R. §91.109: Flight Instruction 

§91.103 provides that no person may operate a civil aircraft (except a manned 

free balloon) that is being used for flight instruction unless that aircraft has 

fully functioning dual controls. UAS’s and remotely piloted aircraft, by their 

design do not have fully functional dual controls. Flight control is accomplished 

through the use of a control box that communicates with the aircraft via radio 

communications. The FAA has approved exemptions for flight training without 

fully functional dual controls for a number of aircraft and for flight instruction 

in experimental aircraft. See Exemption Nos.5778K & 9862A. The equivalent 

level of safety provided by the fact that neither a pilot nor passengers will be 

carried in the aircraft and by the size and speed of the aircraft. Enhancing this 

safety is the technology inherent in the remote controls utilizing digital 

communications, which is paired to the UAS making it nearly impossible to 

unintentionally or intentionally have the control communications interrupted.

14 C.P.R. §91.119: Minimum Safe Altitudes 

FAA Section 333 Exemption Request May 15, 2015

 5 of 12
§91.119 establishes safe altitudes for operation of civil aircraft. §91.119 (d) 

allows helicopters to be operated at less than the minimums prescribed, 

provided the person operating the helicopter complies with any route or 

altitudes prescribed for helicopters by the FAA. As this exemption is for a UAS 

that closely mimics the behavior of a helicopter, and the exemption requests 

authority to operate at altitudes up to 400 feet AGL, an exemption may be 

needed to allow such operations. As set forth herein, the UAS will never 

operate at higher than 400 feet AGL or beyond unaided visual line of sight, 

whichever is closer. It will however be operated in a restricted area with 

individuals tasked with ensuring public safety, and where buildings and people 

will not be exposed to operations without their pre-obtained consent and 

training. The equivalent level of safety will be achieved given the size, weight, 

speed of the UAS as well as the location where it is operated. No flight 

operation will be taken without the permission of the property owner. Because 

of the advance notice to the property owner and participants in the remote 

sensing activity, all affected individuals will be aware of the planned flight 

operations. Compared to flight operations with aircraft or rotor craft weighting 

far more than the maximum 5 lbs. of CSI's UAS’s proposed herein and the lack 

of flammable fuel, any risk associated with these operations is far less than 

those presently presented with conventional aircraft operating at or below 500 

AGL. In addition, the low-altitude operations of the UAS will ensure separation 

between these small- UAS operations and the operations of conventional 

aircraft that must comply with §91.119.

14 C.P.R. §91.121 Altimeter Settings 

§91.121 requires each person operating an aircraft to maintain cruising altitude 

by reference to an altimeter that is set " ... to the elevation of the departure 

airport or an appropriate altimeter setting available before departure:' As the 

UAS may not have a barometric altimeter, but instead a GPS altitude read out, 

an exemption may be needed. An equivalent level of safety will be achieved by 

the operator, confirming the altitude of the launch site shown on the GPS 

altitude indicator before flight. The operator (PIC) will also ensure effective 

pairing with multiple GPS sources to guarantee accurate detection of height.

14 C.P.R. §91.151(a): Fuel Requirements for Flight in VFR Conditions 

§91.151 (a) prohibits an individual from beginning "a flight in an airplane under 

VFR conditions unless (considering wind and forecast weather conditions) there 

is enough fuel to fly to the first point of intended landing, and, assuming 

normal cruising speed (1) During the day, to fly after that for at least 30 

minutes; or (2) At night, to fly after that for at least 45 minutes." The batteries 

powering the UAS’s provide approximately 23 minutes of powered flight in 

hover mode without payload. CSI's UAS’s will not be able to meet the 30-minute 

reserve requirement in 14 CPR §91.151. Operating the small UAS’s, in a tightly 

controlled area where only people and property owners or official 

representatives who have signed waivers will be allowed, with less than 30 

minutes of reserve power, does not engender the type of risks that Section 

91.151(a) was intended to alleviate given the size and speed of the small UAS’s. 

FAA Section 333 Exemption Request May 15, 2015

 6 of 12
CSI believes that an equivalent level of safety can be achieved by limiting 

flights to 10-15 minutes or 25% of battery power whichever happens first. This 

restriction would be more than adequate to return the UAS to its planned 

landing zone from anywhere in its limited operating area. Similar exemptions 

have been granted to other operations, including Exemptions 2689F, 5745, 

10673, and 10808.

14 C.F.R. §91.203 (a) & (b): Carrying Civil Aircraft Certification and 

Registration 

The regulation provides in pertinent part: (a) Except as provided in §91.715, no 

person may operate a civil aircraft unless it has within it the following: (1) An 

appropriate and current airworthiness certificate ... (b) 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. The 

UAS’s fully loaded weigh no more than 5lbs. and are operated without an 

onboard pilot. As such, there is no ability or place to carry certification and 

registration documents or to display them on the UAS’s. An equivalent level of 

safety will be achieved by keeping these documents at the ground control point 

where the pilot flying the UAS will have immediate access to them, to the 

extent they are applicable to the UAS’s. The FAA has issued numerous 

exemptions to this regulation. A representative sample of other exceptions 

includes Exemption Nos. 9565, 9665, 9789, 9789A, 9797, 9797 A, 9816A, and 

10700.

14 C.F.R. §91.405 (a); 407 (a) (1); 409 (a) (2); 417(a) & (b): Maintenance 

Inspections 

These regulations require that an aircraft operator or owner "shall have that 

aircraft inspected as prescribed in subpart E of this part and shall between 

required inspections, except as provided in paragraph (c) of this section, have 

discrepancies repaired as prescribed in part 43 of this chapter ... ;' and others 

shall inspect or maintain the aircraft in compliance with Part 43. Given that 

these section and Part 43 apply only to aircraft with an airworthiness 

certificate, these sections will not apply to the applicant. The operator, 

pursuant to the flight manual, will provide maintenance. An equivalent level of 

safety will be achieved because these small UAS’s are very limited in size and 

will carry a small payload and operate only in restricted areas for limited 

periods of time. If mechanical issues arise the UAS can land immediately and 

will be operating from no higher than 400 feet AGL. CSI will ensure that the 

UAS is in working order prior to initiating flight and keep a log of any 

maintenance performed. Moreover, CSI’s trained staff professionals are familiar 

with the aircraft and are best suited to maintain the aircraft in an airworthy 

condition to provide the equivalent level of safety.

FAA Section 333 Exemption Request May 15, 2015

 7 of 12
Conditions and Limitations 

CSI has reviewed the conditions and limitations given below from one of the 

recent Section 333 exemptions granted and we are willing to abide by the rules 

outlined below. New rules that are not listed below will also be followed if 

required for an exemption.

1. Operations authorized by this grant of exemption are limited to the DJI 

Phantom, and DJI Inspire 1 when weighing less than 55 pounds including 

payload. Proposed operations of any other aircraft will require a new petition 

or a petition to amend this exemption. 

2. Operations for the purpose of closed-set motion picture and television 

filming are not permitted. 

3. The UA may not be operated at a speed exceeding 87 knots (100 miles per 

hour). The exemption holder may use either groundspeed or calibrated 

airspeed to determine compliance with the 87 knot speed restriction. In no 

case will the UA be operated at airspeeds greater than the maximum UA 

operating airspeed recommended by the aircraft manufacturer. 

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

ground level (AGL). Altitude must be reported 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 or U.S. driver’s license. 

6. All operations must utilize a visual observer (VO). The UA must be operated 

within the visual line of sight (VLOS) of the PIC and VO at all times. The VO 

may be used to satisfy the VLOS requirement as long as the PIC always 

maintains VLOS capability. The VO 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 VO can perform the duties required of the VO. 

7. This exemption and all documents needed to operate the UAS and conduct 

its operations in accordance with the conditions and limitations stated in this 

grant of exemption, are hereinafter referred to as the operating documents. 

The operating documents must be accessible during UAS operations and made 

available to the Administrator upon request. If a discrepancy exists between 

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

the operating documents, 4 the conditions and limitations herein 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 

FAA Section 333 Exemption Request May 15, 2015

 8 of 12
revisions and present updated and revised documents to the Administrator or 

any law enforcement official upon request. The operator must also present 

updated and revised documents if it petitions for extension or amendment to 

this grant of exemption. If the operator determines that any update or revision 

would affect the basis upon which the FAA granted this exemption, then the 

operator must petition for an 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. 

8. 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 prior to conducting further 

operations under this exemption. Functional test flights may only be conducted 

by a PIC with a VO and must remain at least 500 feet from other people. The 

functional test flight must be conducted in such a manner so as to not pose an 

undue hazard to persons and property. 

9. The operator is responsible for maintaining and inspecting the UAS to ensure 

that it is in a condition for safe operation. 

10. Prior to each flight, the PIC must conduct a pre-flight inspection and 

determine the UAS is in a condition for safe flight. The pre-flight inspection 

must account for all potential discrepancies, e.g. inoperable components, 

items, or equipment. 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. 

11. The operator must follow the UAS manufacturer’s maintenance, overhaul, 

replacement, inspection, and life limit requirements for the aircraft and 

aircraft components. 

12. Each UAS operated under this exemption must comply with all 

manufacturer safety bulletins. 

13. Under this grant of exemption, a PIC must hold either an airline transport, 

commercial, private, recreational, or sport pilot certificate. The PIC must 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 must 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. 5 

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

demonstrates the ability to safely operate the UAS in a manner consistent with 

how the UAS will be operated under this exemption, including evasive and 

emergency maneuvers and maintaining appropriate distances from persons, 

vessels, vehicles and structures. PIC qualification flight hours and currency 

FAA Section 333 Exemption Request May 15, 2015

must be logged in a manner consistent with 14 CFR § 61.51(b). Flights for the 

purposes of training the operator’s PICs and VOs (training, proficiency, and 

experience-building) and determining the PIC’s ability to safely operate the 

UAS in a manner consistent with how the UAS will be operated under this 

exemption are permitted under the terms of this exemption. However, training 

operations may only be conducted during dedicated training sessions. During 

training, proficiency, and experience-building flights, all persons not essential 

for flight operations are considered nonparticipants, and the PIC must operate 

the UAS with appropriate distance from nonparticipants in accordance with 14 

CFR § 91.119. 

15. UAS operations may not be conducted during night, as defined in 14 CFR § 

1.1. All operations must be conducted under visual meteorological conditions 

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

16. The UA may not operate within 5 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 the exemption holder. The letter of agreement with the airport 

management must be made available to the Administrator or any law 

enforcement official upon request. 

17. 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. 

18. If the UAS loses communications or loses its GPS signal, the UA must return 

to a pre-determined location within the private or controlled-access property. 

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

emergencies. 

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

forecast weather conditions) there is enough available power for the UA 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. 

21. Air Traffic Organization (ATO) Certificate of Waiver or Authorization (COA). 

All operations shall be conducted in accordance with an ATO-issued COA. The 

exemption holder may apply for a new or amended COA if it intends to conduct 

operations that cannot be conducted under the terms of the attached COA. 6 

22. All aircraft operated in accordance with this exemption must be identified 

by serial number, registered in accordance with 14 CFR part 47, and have 

identification (N−Number) markings in accordance with 14 CFR part 45, Subpart

Administrator or any law enforcement official upon request. 

24. The UA must remain clear and give way to all manned aviation operations 

and activities at all times. 

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

vehicle. 

26. All Flight operations must be conducted at least 500 feet from all 

nonparticipating 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 in a 

manner ensuring the safety of nonparticipating persons; and b. The owner/

controller of any vessels, vehicles or structures has granted permission for 

operating closer to those objects 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. 

The PIC, VO, operator trainees or essential persons are not considered 

nonparticipating persons under this exemption. 

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

with permission from the property owner/controller or authorized 

representative. Permission from property owner/controller or authorized 

representative will be obtained for each flight to be conducted.

Summary

Satisfaction of the criteria provided in Section 333 of the Reform Act - size, weight, 

speed, operating capabilities, proximity to airports and populated areas, operation 

within visual line of sight, and national security considerations - provides more than 

adequate justification for the grant of the requested exemptions to permit CSI to 

operate DJI Phantom 3 Professional and DJI Inspire 1 for commercial purposes. 

Granting the requested exemption will benefit the public interest as a whole in many 

ways, including (1) significantly improving safety and reducing risk by alleviating 

human exposure to danger; (2) improving the quality of services CSI can provide to its 

customers; and (3) decreasing operating costs related to site investigation and 

inspection activities.

Phantom 3 Professional-Aircraft

From DJI Wiki

Aircraft

Flight Controller

The Phantom 3 Professional’s flight controller features several important upgrades, including a new flight mode. Safety

modes include Failsafe and Return-to-Home. These features ensure the safe return of your aircraft if the control signal is

lost. The flight controller can also save critical flight data from each flight to the on-board storage device. The new flight

controller also provides increased stability and a new air braking feature.

Flight Mode

Three flight modes are available. The details of each flight mode are found below:

P-mode (Positioning) : P-mode works best when GPS signal is strong. There are three different states of P-mode, which

will be automatically selected by the Phantom 3 Professional depending on signal strength of GPS and Vision Positioning

sensors :

P-GPS: GPS and Vision Positioning both are available. The aircraft is using GPS for positioning.

P-OPTI: Vision Positioning is available but the GPS signal strength is not sufficient. The aircraft is using only the Vision

Positioning System for positioning.

P-ATTI: Neither GPS nor Vision Positioning is available. The aircraft is using only its barometer for positioning, so only

altitude can be stabilized.

A-mode (Attitude): GPS and Vision Positioning System are not used for stabilization. The aircraft only uses its

barometer. The aircraft can still automatically return to the home point if the control signal is lost and the Home Point was

recorded successfully.

F-mode (Function): Intelligent Orientation Control (IOC) is activated in this mode. For more information about IOC, refer

to the IOC section in the Appendix.

Tips:

Use the Flight Controller mode switch to change the flight mode of the aircraft, refer to the “Flight Mode Switch” for

more information.

Flight Status Indicator

The Phantom 3 Professional has Front LEDs and Aircraft Status Indicators. The positions of these LEDs are shown in the

figure below:
5/15/2015 Phantom 3 Professional-Aircraft - DJI Wiki

http://wiki.dji.com/en/index.php/Phantom_3_Professional-Aircraft 2/13

The Front LEDs show the orientation of the aircraft. The Front LEDs glow solid red when the aircraft is turned on to

indicate the front (or nose) of the aircraft. The Aircraft Status Indicators communicate the system status of the flight

controller. Refer to the table below for more information about the Aircraft Status Indicators:

Aircraft Status Indicator Description

Return-to-Home (RTH)

The Return-to-Home (RTH) function brings the aircraft back to the last recorded Home Point. There are three types of

RTH procedures: Smart RTH, Low Battery RTH, and Failsafe RTH. This section describes these three scenarios in detail.
5/15/2015 Phantom 3 Professional-Aircraft - DJI Wiki

http://wiki.dji.com/en/index.php/Phantom_3_Professional-Aircraft 3/13

Smart RTH

Use the RTH button on the remote controller or tap the RTH button in the DJI Pilot app and follow the on-screen

instructions when GPS is available to initiate Smart RTH. The aircraft will then automatically return to the last recorded

Home Point. You may use the remote controller’s control sticks to control the aircraft’s position to avoid a collision

during the Smart RTH process. Press and hold the Smart RTH button once to start the process, and press the Smart RTH

button again to terminate the procedure and regain full control of the aircraft.

Low Battery RTH

The low battery level failsafe is triggered when the DJI Intelligent Flight Battery is depleted to a point that may affect the

safe return of the aircraft. Users are advised to return home or land the aircraft immediately when prompted. The DJI Pilot

app will display a notice when a low battery warning is triggered. The aircraft will automatically return to the Home Point

if no action is taken after a ten-second countdown. The user can cancel the RTH procedure by pressing the RTH button on

the remote controller. The thresholds for these warnings are automatically determined based on the aircraft’s current

altitude and distance from the Home Point.

The aircraft will land automatically if the current battery level can only support the aircraft long enough to descend from

its current altitude. The user can still use the remote controller to alter the aircraft’s orientation during the landing process.

The Battery Level Indicator is displayed in the DJI Pilot app, and is described below:
5/15/2015 Phantom 3 Professional-Aircraft - DJI Wiki

http://wiki.dji.com/en/index.php/Phantom_3_Professional-Aircraft 4/13

Tips:

When the Critical battery level warning is triggered and the aircraft begins to land automatically, you may push the

throttle upward to make the aircraft hover at its current altitude, giving you an

opportunity to navigate to a more appropriate landing location.

The colored zones and markers on the battery level indicator bar reflect the estimated remaining flight time. They

are automatically adjusted according to the aircraft’s current location and status.

Failsafe RTH

If the Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH will be automatically

activated if the remote controller signal is lost for more than three seconds. The Returnto- Home process may be

interrupted and the operator may regain control of the aircraft if the remote controller signal connection is re-established.

Failsafe Illustration
5/15/2015 Phantom 3 Professional-Aircraft - DJI Wiki

http://wiki.dji.com/en/index.php/Phantom_3_Professional-Aircraft 5/13

Notes:

The aircraft cannot avoid obstruction during the Failsafe RTH, therefore, it is important to set an suitable Failsafe

altitude before each flight. Launch the DJI Pilot app and enter “Camera” and select “MODE > Advanced Settings >

Failsafe mode” to set the Failsafe altitude.

The aircraft will stop its ascent and return to the Home Point immediately if the throttle stick is moved during the

Failsafe RTH procedure.

Vision Positioning System

The DJI Vision Positioning System uses ultrasound and image data to help the aircraft maintain its current position. With

the help of Vision Positioning, your Phantom 3 Professional can hover in place more precisely and fly indoors or in other

environments where a GPS signal is not available. The main components of the Vision Positioning System are located on

the bottom of your Phantom 3 Professional; they include [2] two ultrasonic sensors and [1] one monocular camera.

Using Vision Positioning

Vision Positioning is activated automatically when the Phantom 3 Professional is turned on. No further action is required.

Vision Positioning is typically used in indoor environments, where GPS is unavailable. Using the sensors that are built

into the Vision Positioning system, the Phantom 3 Professional can hover precisely even without GPS.
5/15/2015 Phantom 3 Professional-Aircraft - DJI Wiki

http://wiki.dji.com/en/index.php/Phantom_3_Professional-Aircraft 6/13

Follow the steps below to use Vision Positioning:

1. Toggle the flight mode switch to P-mode.

2. Place the aircraft on a flat surface. Note that the Vision Positioning system cannot work properly on surfaces without

clear pattern variations.

3. Turn on the aircraft. The aircraft status indicator will flash green two times, which indicates the Vision Positioning

system is ready. Gently push the throttle up to lift off and the aircraft will hover in place.

Notes:

The performance of your Vision Positioning System is affected by the surface over which it is flying. The ultrasonic

sensors may not be able to accurately measure distances when operating above sound-absorbing materials. In addition, the

camera may not function correctly in suboptimal environments. The aircraft will switch from P-mode to A-mode

automatically if neither GPS nor Vision Positioning System are available. Operate the aircraft with great caution in the

following situations:

Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green).

Flying over a highly reflective surfaces.

Flying at high speeds(over 8 m/s at 2 meters or over 4 m/s at 1 meter).

Flying over water or transparent surfaces.

Flying over moving surfaces or objects.

Flying in an area where the lighting changes frequently or drastically.

Flying over extremely dark (lux < 10) or bright (lux > 100,000) surfaces.

Flying over surfaces that can absorb sound waves (e.g. thick carpet).

Flying over surfaces without clear patterns or texture.

Flying over surfaces with identical repeating patterns or textures (e.g. tiles with the same design).

Flying over inclined surfaces that will deflect sound waves away from the aircraft.

Tips:
5/15/2015 Phantom 3 Professional-Aircraft - DJI Wiki

http://wiki.dji.com/en/index.php/Phantom_3_Professional-Aircraft 7/13

Keep the sensors clean at all times. Dirt or other debris may adversely affect the effectiveness of the sensors.

Vision Positioning is only effective when the aircraft is at altitudes of 0.3 to 3 meters.

The Vision Positioning System may not function properly when the aircraft is flying over water.

The Vision Positioning System may not be able to recognize pattern on the ground in low light conditions (less than

100 lux).

Do not use other ultrasonic devices with frequency of 40 KHz when Vision Positioning system is in operation.

Vision Positioning System may not be able to stabilize the aircraft when flying close to the ground (below 0.5

meters) at fast speeds.

Warning:

Keep animals away from the aircraft when Vision Positioning system is activated. The sonar sensor emits high frequency

sounds that are only audible to some animals.

Flight Recorder

Flight data is automatically recorded to the internal storage of the aircraft. This includes flight telemetry, aircraft status

information, and other parameters. To access these data, connect the aircraft to the PC through the Micro-USB port and

launch the DJI Pilot app.

Attaching and Detaching the Propellers

Use only DJI approved propellers with your Phantom 3 Professional. The grey and black nuts on the propeller indicate

where they should be attached and in which direction whey should spin. To attach the propellers properly, match the nut

color with the motor axis color.

Attaching the Propellers

1. Be sure to remove the warning stickers from the motors before attaching the propellers.

2. Attach the propellers with silver dots onto the motors with silver axes and spin the propellers clockwise to secure them

in place. Attach the propellers with black dots onto the motors with black axes and spin the propellers counter-clockwise

to secure them in place. Be sure to tighten each propeller by hand before flight.
5/15/2015 Phantom 3 Professional-Aircraft - DJI Wiki

http://wiki.dji.com/en/index.php/Phantom_3_Professional-Aircraft 8/13

Notes:

Ensure propellers are attached to its corresponding motors, otherwise the aircraft cannot take off.

Wear gloves when handling propellers.

Hand tighten each of the propellers on the corresponding motors to ensure it is attached firmly.

Detaching the Propellers

Hold the motor in place with one hand, then spin the propeller in the indicated unlock direction.

Notes:

Check that the propellers and motors are installed correctly and firmly before every flight.

Ensure that all propellers are in good condition before each flight. DO NOT use aged, chipped, or broken

propellers.

To avoid injury, STAND CLEAR of and DO NOT touch propellers or motors when they are spinning.

ONLY use original DJI propellers for a better and safer flight experience.

DJI Intelligent Flight Battery

The DJI Intelligent Flight Battery has a capacity of 4480 mAh, a voltage of 15.2 V, and a smart charge/ discharge

functionality. It should only be charged using an appropriate charger that has been approved by DJI..

Note:
5/15/2015 Phantom 3 Professional-Aircraft - DJI Wiki

http://wiki.dji.com/en/index.php/Phantom_3_Professional-Aircraft 9/13

The Intelligent Flight Battery must be fully charged before using it for the first time. Refer to "Charging the Intelligent

Flight Battery" for more information.

Tips:

Be aware that the output power of the supplied Phantom 3 Professional charger is 100 W.

DJI Intelligent Flight Battery Functions

1. Battery Level Display: the LED indicators display the current battery level.

2. Battery Life Display: the LEDs display the current battery power cycle.

3. Auto-Discharging Function: To prevent swelling, the battery automatically discharges to below 65% of total power

when it is idle for more than ten days. It takes around two days to discharge the battery to 65%. It is normal to feel

moderate heat being emitted from the battery during the discharge process. Discharge thresholds can be set in the DJI

Pilot app.

4. Balanced Charging: Automatically balances the voltage of each battery cell when charging.

5. Overcharge Protection: Charging automatically stops when the battery is fully charged.

6. Temperature Detection: The battery will only charge when the temperature is between 0°C (32°F) and 40°C (104°F).

7. Over Current Protection: The battery stops charging when high amperage (more than 8 A) is detected.
