RE: Petition for Exemption from Certain Federal Aviation Regulations according 

to Section 333 of the FAA Modernization and Reform Act of 2012 

Dear Sir or Madam: 

Dynamic Aerial Services (DAS) is applying for an exemption from the Code of 

Federal Regulations as detailed below.

The exemption would permit commercial operation of a small unmanned aircraft 

system (SUAS) in the national airspace (NAS) as regulated by the FAA for aerial data 

collection, for the following uses:

I. Remote sensing and measuring by an instrument(s) aboard the UA including

A. imagery (photography, video, infrared, etc.)

B. electronic measurement (precision inspection, RF analysis, etc.)

C. chemical measurement (particulate measurement, etc.)

D. or any other gathering of data by instruments aboard the UA.

II. Assisting in maintaining public safety in times of emergency including

A. aerial photography and evaluation of emergency response scenes and 

operations with DAS agreement

B. aid in emergency services support and search and rescue with DAS

agreement
DAS333a102615 2

All operations performed by are cost effective and protect the public by reducing the 

size of the aircraft from one weighing up to several tons to one weighing less than 55 

pounds. In addition, the UA does not use flammable liquid fuel. Instead, it operates on 

high-energy batteries. The UA is flown in the lower strata of controlled and 

uncontrolled airspace, at 400 ft. AGL and below. DAS commercial operations will be 

performed according to FAA regulations or amended FAA regulations as permitted

under a Section 333 Grant of Exemption.

BACKGROUND AND REFERENCES

In support of the petition and the FAA’s evaluation process, we reference previously 

granted 333 exemption petitions by the FAA with same or similar purposes as follows:

DESCRIPTION OF UNMANNED AIRCRAFT SYSTEMS

DAS wishes to fly in its operations:

• The Yuneec Typhoon Q500

as its inspection aircraft.

The Yuneec Typhoon Q500 4K

The Typhoon Q500 4K is a vertical takeoff and landing unmanned aircraft of quadcopter 

design. Manufactured by Yuneec International Co. Ltd., the Typhoon Q500 4K has the 

world's first Smart Transmitter (the "ST-10 series Ground Station" with 10 channels) 

combining a 2.4GHz radio control transmitter with a 5.8GHz digital video link. It 

operates on a built-in Android touch screen. Safety features include Geo Fencing, Home 

Mode and Return Home. Geo Fencing prohibits the aircraft from exceeding a 

programmed permitted radius. When activated, Home Mode will automatically return the 

aircraft within a 10-foot radius of its starting point. Should the transmitter signal be lost 

or visual line of sight with the aircraft impaired, upon signal, Return Home will 

automatically take control of the aircraft and return it to the operator/base station. 

Takeoff weight with manufacture provided camera and gimbal payload and battery is 3.75 

lbs.

The Typhoon Q500 4K dimensions are 9.45 in (210mm) x 16.54 in (420mm), with a 

diagonal of 20 in (510mm) from motor to motor. It can fly up to 25 minutes on its 

5400mAh 3S 11.1V lithium polymer battery. Radio control and video transmission 

systems meet FCC requirements for operation in the unlicensed spectrum of 5.8 GHz 

ranges. The operating manual of the Typhoon Q500 warns against using the aircraft in 

areas where radio interference is possible, as does the Flight Operations manual (FOM), 

along with procedures to ensure radio safety with the UAS. 

EXTENT OF RELIEF SOUGHT AND WHY 

DAS asks for relief from regulations tabled below, which the authority of the FAA has 

previously granted in exemption certificates number 11062 along with six others 

described as “in commonality”, and in number 11109, which are for use of electric 
DAS333a102615 5

rotorcraft. The FOM incorporates the conditions and limitations of these grants of 

exemption, and in some cases imposes stricter limits on its own operations.

There is no passenger or pilot on 

board the UA, thus safety issues 

are different from a manned flight. 

DAS’s aircraft have programmable 

automated safety features and 

emergency responses, have preflight checks for safety beyond 

commercial manned aircraft, can 

be geographically restricted by 

operator with programmable 

control points, have 

communications with the PIC 

regarding fuel loss and other flight 

hazards. PIC will have ground 

school training certificate and 

additional 25 hours logged flight

Minimum safe 

altitudes over other 

than congested 

area 

Operating closer than 500 

feet to a person, vehicle, or 

structure may be necessary 

for pipeline and equipment 

inspection. 

People will not be allowed over, 

under or within 500 feet laterally 

of the aircraft in flight. Some 

flights may require the 

participation or guidance of 

industry personnel, positioned as 

close as 200 feet, will brief them

91.121 Altimeter settings Procedures to set and 

confirm altitude do not 

provide for operation of 

remote telemetry to SUAS 

pilot. 

An onboard air pressure sensor 

and software resolve height 

differences as small as one 

centimeter. Altitude is controlled 

by measuring air pressure and the 

z-axis accelerometer/GPS values. 

The starting point is a relative 

height measurement calculated by 

the flight controller. Altitude 

above ground is displayed on the 

pilot's handheld controller by 

telemetry, and alarms can signal 

conditions of interest. 400 feet 

AGL is the maximum permissible

(b) 

Fuel requirements 

for flight in VFR 

conditions

Rotorcraft under VFR 

must carry enough fuel to 

reach first landing point 

and then another 20 

minutes. The multirotor 

aircraft specified in this 

petition is designed to fly 

missions of 25-minute

durations. 

On aircraft specified, battery 

voltage under load is displayed on 

the pilot's handheld controller 

during flight. Battery chemistry 

does not support adequate current 

discharge below about 3 v per cell. 

Circuitry in the onboard flight 

controller measures voltage and 

will start a failsafe procedure to 

land before summed minimums 

are reached. In the event that one 

or more cells fail, these minimums 

may be reached sooner than 

expected, due to rapid current 

drain against a smaller number of 

functioning cells. DAS pilots are 

trained to monitor voltage and 

recognize abnormal discharge in 

flight and to land sooner than 

forced. If 20 minutes of flight time 

or 25% of reserve voltage under 

load is reached, pilot must 

commence landing.

PILOT IN COMMAND AND CREW 

The pilot in command (PIC) must hold an airman’s certification recognized by the FAA 

such as an airline transport, commercial, private, recreational, sport pilot, or glider pilot 

(powered or non-powered) and must comply with the training and testing specified in the 

FOM. The PIC must hold a current FAA airman medical certificate as required by the 

class of airman certification. In the case of the sport pilot certification, the PIC must 

possess a valid U.S. driver’s license issued by a State, the District of Colombia, Puerto 

Rico, a territory, a possession, or the Federal government. The PIC must comply with the 

training and testing specified in the operator’s manual. The PIC must remain in radio 

communication with a visual observer who complies with the training and testing 

specified in the operator’s manual. The pilot must be able to acquire the aircraft with his 
DAS333a102615 11

own vision according to eye standards for a third class airman medical certificate or valid 

driver’s license according to the issuing State. The PIC must operate within visual line of 

sight only, and be able to see the attitude and orientation of the aircraft by himself. If 

GPS or magnetometer is compromised, certain safety features may not operate, and the 

pilot must understand by their training and experience how to recover control. 

OPERATION OF THE UNMANNED AIRCRAFT 

The aircraft will be under the operational control of DAS’s PIC. 

1. Operations for the purpose of closed-set motion picture and television filming will 

not be permitted.

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

Either groundspeed or calibrated airspeed will be used 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.

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

level (AGL). Altitude will be reported in feet AGL.

4. The UA will 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.

5. All operations will utilize a visual observer (VO). The UA will be operated within 

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

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

capability. The VO and PIC will be able to communicate verbally at all times; 

electronic messaging or texting will not be permitted during flight operations. The 

PIC will be designated before the flight and will not transfer his or her designation 

for the duration of the flight. The PIC will ensure that the VO can perform the 

duties required of the VO.

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

operations in accordance with the conditions and limitations stated in an approved 

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

operating documents will be accessible during UAS operations and made available 
DAS333a102615 12

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

and limitations in the granted exemption(s) and the procedures outlined in the 

operating documents, the conditions and limitations in the granted exemption will 

take precedence and will be followed. Otherwise, the operator will follow the 

procedures as outlined in its operating documents. The operator may update or 

revise its operating documents. The operator will track such revisions and present 

updated and revised documents to the Administrator or any law enforcement 

official upon request. The operator will also present updated and revised 

documents if it petitions for extension or amendment to a granted exemption. If 

the operator determines that any update or revision would affect the basis upon 

which the FAA granted the requested exemption, then the operator will petition 

for an amendment to its grant of exemption. The FAA’s UAS Integration Office 

(AFS−80) will be contacted if questions arise regarding updates or revisions to the 

operating documents.

7. Any UAS that requires maintenance or alterations that affect the UAS operation or 

flight characteristics, e.g., replacement of a flight critical component, will undergo a 

functional test flight prior to conducting further operations under this exemption. 

Functional test flights will only be conducted by a PIC with a VO and will remain 

at least 500 feet from other people. The functional test flight will be conducted in 

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

8. The operator will be responsible for maintaining and inspecting the UAS to ensure 

that it is in a condition for safe operation.

9. Prior to each flight, the PIC will conduct a pre-flight inspection and determine the 

UAS is in a condition for safe flight. The pre-flight inspection will 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 will be prohibited from operating until the necessary maintenance has been 

performed and the UAS is found to be in a condition for safe flight.

10.The operator will follow the UAS manufacturer’s maintenance, overhaul, 

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

components.

11.Each UAS operated under this exemption will comply with all manufacturer safety 

bulletins.

12.The PIC will hold either an airline transport, commercial, private, recreational, or 

sport pilot certificate. The PIC will also hold a current FAA airman medical 

certificate or a valid U.S. driver’s license issued by a state, the District of Columbia, 
DAS333a102615 13

Puerto Rico, a territory, a possession, or the Federal government. The PIC will 

also meet the flight review requirements specified in 14 CFR § 61.56 in an aircraft 

in which the PIC is rated on his or her pilot certificate.

13.The operator will 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 a granted exemption, including evasive and emergency maneuvers 

and maintaining appropriate distances from persons, vessels, vehicles and 

structures. PIC qualification flight hours and currency will be logged in a manner 

consistent with

14. 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 will be permitted only under the terms of this exemption. 

However, training operations will 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 will 

operate the UA with appropriate distance from nonparticipants in accordance with 

14 CFR § 91.119.

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

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

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

16.The UA will 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 will 

be made available to the Administrator or any law enforcement official upon 

request.

17.The UA will 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 will return to a 

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

19.The PIC will abort the flight in the event of unpredicted obstacles or emergencies.
DAS333a102615 14

20.The PIC will be 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 5 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 will be conducted in accordance with an ATO-issued COA. If 

operations cannot be conducted under the terms of a granted COA, the operator 

will apply for a new or amended COA.

22.All aircraft operated in accordance with a granted exemption will 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 will 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 will be 

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

aircraft is operating.

24.These documents will be made available to the Administrator or any law 

enforcement official upon request.

25.The UA will remain clear and give way to all manned aviation operations and 

activities at all times.

26.The UAS will not be operated by the PIC from any moving device or vehicle.

27.All Flight operations will 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 will 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 will 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, 
DAS333a102615 15

operator trainees or essential persons are not considered nonparticipating 

persons under this exemption.

28.All operations will 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.

29.Any incident, accident, or flight operation that transgresses the lateral or vertical 

boundaries of the operational area as defined by the applicable granted COA will 

be reported to the FAA's UAS Integration Office (AFS−80) within 24 hours. 

Accidents will be reported to the National Transportation Safety Board (NTSB) 

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

BENEFIT TO THE PUBLIC 

Approval of this petition allowing commercial operations of SUASs will enhance safety 

by reducing public safety risk. The use of battery powered UAs fore aerial inspection, 

geo-mapping and image and film capture, is more environmentally sound and safe 

compared to a conventional, liquid-fueled aircraft. It provides a smaller environmental 

footprint, decreases manpower and separates the aircraft operators form the aircraft. The 

use of the specified sUASs further protects the public by being used in restricted 

environments and reducing impact hazards.

REASONS WHY THE EXEMPTION WOULD NOT ADVERSELY AFFECT 

SAFETY 

The inspection aircraft will be operated in accordance with DAS safety protocols 

The inspection aircraft carries no person, cargo, or flammable liquid fuel. Its size and 

weight are a small fraction of any manned aircraft, and its safety systems reflect best 

design practices in the SUAS industry. 

In addition, DAS will keep the approved at its ground control station. The PIC will have 

immediate access to it. Previous exemptions granted by the FAA concerning Section 

91.9(b) establish that safety is not adversely affected when the approved Aircraft Flight 
DAS333a102615 16

Manual is kept at the ground control station of a SUAS, where it can be immediately 

accessed by the PIC.

When properly operated by trained pilots, a well-designed SUAS can stay clear of people 

and property on the ground and in the air. Procedures, airmanship skills, training and 

testing requirements for SUAS personnel in the will let the operator achieve safety levels 

in the NAS and on the ground that are equivalent to or greater than that in manned 

aviation 

SUMMARY FOR PUBLICATION 

The following summary may be published in the Federal Register: 

DAS requests an exemption from: 

14 CFR Parts 61.113 (a) and (b) 

14 CFR Parts 91.119 (c), 91.121, 91.151 (b), 91.405 (a) and (b), 91.407 (a) (1), 91.409 (a) 

(1), 91.409 (a) (2), 91.417 (a) 

in order to operate a small unmanned aircraft system (SUAS) for purposes of aerial 

inspections and monitoring, aerial geo-mapping, aerial imaging and filming, aerial data 

collection and public safety in times of emergency. The PIC will be appropriately 

qualified with a current FAA approved pilot certificate for SUAS operation and 

specialized training.

Imagery, electronic measurement, chemical measurement or any other gathering of data 

to be done by instruments aboard the UA, are conventionally done by manned aircraft 

operations, which use liquid fuel and weigh upwards of 5,000 lbs. These operations must 

fly the aircraft to and from the operation’s location. The use of the Yuneec Typhoon 

Q500 4K which weighs less than 15 lbs. and is equipped with flight control and safety

features that prevent flyaways, minimizes the risk from that of a manned aircraft to 

people and property allowed within and outside the zone of operations. 

Flight operations outside the secure areas are not allowed. There are no impacts to 

privacy.
