UAS are often seen as superior to manned helicopters due to the smaller size and lower costs, reduced 

noise and as such, a much smaller environmental and safety impact.

The petitioner requests exemption to operate a Yuneec, Q500+ Typhoon equipped with a three-axis 

CGO2 Gimbal and Camera, both products of Yuneec. This sUAS has a pre-programmed limit for the 

altitude above ground level at 400 feet and a Geo fence while in Smart Mode with a distance limit of 300 

feet from the controller. These limits are preset at the factory and will be kept at those limits, which 

currently comply with the AMA’s and FAA requirement for Visual Line of Sight limitation and an AGL 

limitation. The ground station is also programmed with a safety feature that disables motor start up if 

within Class B, and C airspace boundaries. The Q500+ also has the failsafe-automated feature of return 

to home in the event that communication is lost between the ground station and the aircraft.

In addition to the requirements already set forth by C.F.R. Title 14 and the applicable FAR, The petitioner 

will--

a. Only operate its UAS in direct visual line of sight of the pilot and observer without use of a visual aid 

other than corrective lenses. 

b. Operate at an altitude no greater than 400 feet above the ground. 

c. Operate with due vigilance and known practiced see and avoid scanning techniques to avoid any 

conflicts with manned or other UAS aircraft that may enter the UAS operating area. The UAS flight will 

be immediately terminated if a potential conflict may exist. 

d. Operate over private or public sites only with prior permission from property owner or owner’s agent 

or legal authorities as allowed by law. 

e. Terminate flight when any unsafe condition exists. 

f. Terminate flight when battery voltage drops to 30% of battery capacity or when the 1st low battery 

alert occurs per the Q500+ Typhoon Instruction Manual, not to exceed 18 minutes run time. 

g. Operate at a ground speed of 0 to 15 mph during on site missions. 

h. Operate in accordance with the guidance and standards set forth by the AMA, the UAS manufacturer 

and the administrator. 

i. Operate with a minimum crew for each operation consisting of the PIC and a visual observer in direct 

communication utilizing appropriate verbal, radio or cell phone as needed. 

j. Insure the sUAS operator on the controls will be at least a current Private Pilot with a class III medical. 

k. Provide ground instruction with standards and content currently accepted by the administrator for 

private pilot knowledge testing, to the observer and or UAS. 

The petitioner requests exemption from 14 CFR part 61.113 Private Pilot Privileges, Pilot in Command 

Section (a). The petitioner may elect to utilize certified private pilots with class III medicals to conduct 

operations with the sUAS. In the Grant of Exemption No. 11062 to Astraeus Aerial (Astraeus), the FAA 

determined that a PIC with a private pilot certificate operating the Astraeus UAS would not adversely 

affect operations in the NAS or present a hazard to persons or property on the ground. The petitioner 

requests the same consideration and limitations as previously granted.
Title 14 CFR part 91.7(a) Civil Aircraft Airworthiness. As no Airworthiness Certificate is available for this 

sUAS the petitioner requests exemption under this part utilizing a preflight inspection and the 

manufacturers documents for determining compliance of the sUAS airworthiness. The petitioner 

warrants compliance to part 91.7(b) in that the operation will only be conducted after a thorough 

preflight and pre-mission planning inspection is completed, to include current and forecast weather, 

airspace, notams, area of operations, and notice issued to non-participating persons in local proximity. 

The petitioner will utilize the Yuneec, Q500+ Instruction manual, quick start guide and the petitioners 

own pre-flight checklist included in the attached supplements to determine the sUAS airworthiness. 

The petitioner requests exemption from 14 CFR part 91.119(c) Minimum Safe Altitudes. 

The petitioner requests exemption from Section (c) with the following conditions and limitations. The 

petitioner requests the exemption due to the scope of the operations to be performed and the 

requirement to operate below 400 feet AGL. The Petitioners primary mission would be to record data or 

survey of persons, property or structures as listed above. The sUAS size, weight, speed and limited 

operating times and area, as well as the soft materials used in the construction of the sUAS, would 

provide an equivalent or greater level of safety as intended under this part.

The Q500+ is a helicopter as defined by CFR Title 14, FAR Part 1, general definitions. The sUAS has a

vertical to near vertical descent in the event of a power failure. Fly-a-ways would be the greatest or 

most dangerous risk to non-participating persons. The Q500+ has no documented (fly-away), while 

operated under GPS lock within the parameters of the Q500+ operating instructions. The Q500+ is a very 

stable, low rotor speed sUAS that maneuvers, under GPS lock, relatively slow compared to similar sized 

UAS. In an emergency the sUAS would be quickly brought down per the loss of control procedure as 

described in the emergency procedures checklist, adequate time to complete the procedure would exist 

due to the 0 to 15 mph operational groundspeed of the Q500+. The risk to persons 100 feet away would 

be at no greater risk than persons located 500 feet away. The petitioner requests exemption from the 

500-foot altitude restriction and the 500-foot stand off restriction from persons, property or vessel 

applied to previous grants of exemptions. The exemption is requested with the following conditions and 

limitations in conducting the petitioners operation—

a. The sUAS will be operated at an altitude of no more than 400 feet above ground level. 

b. The sUAS will not be operated at greater than a 400-foot slant distance from the PIC. 

c. The sUAS will not be operated over any non-participating person. 

d. The sUAS will not be operated over a non-participating property, structure or vessel without prior 

permission from the property owner or legal representative. 

e. The sUAS will maintain a minimum slant distance of 100 feet from any non-participating person and 

will increase the distance proportionally by 50 ft. per 50 ft. of altitude. At no time will the sUAS be 

operated closer than a 100-foot slant distance to a non-participating person unless that person is behind 

a protective barrier or shielded from possible debris in the event of a crash. 

f. A minimum of 2 hour notice will be distributed to all residences or businesses of a scheduled 

operation in an urban business or residential area within 500 feet of the operation, informing of the 

time, location and safety hazards to persons or property, the notice will include a phone number to 

voice objections or concerns. 

g. Warning signs will be displayed on the perimeter of the safety zone to alert passers-by of the hazard 

and warning to stay back and behind cover. If the safety zone is breeched, flight will be immediately 

terminated. 

h. The sUAS will be operated over public rural lands with the same stand off distance and altitude 

restrictions afforded persons, property and vessels per e. above. 
The petitioner requests exemption from 14 CFR Part 91.121, Altimeter settings. The UAS will not have 

a typical barometric altimeter onboard the aircraft, the petitioner intends to operate the UA within 

VLOS and at or below 400 feet AGL, combined with the petitioner’s intention to limit the altitude of the 

UAS through flight limit function on the UAS, has been previously ruled to be a sufficient method for 

ensuring the UAS operations do not adversely affect safety. The altitude information will be generated 

by GPS equipment installed onboard the aircraft, and/or a static pressure sensor (barometer), which 

aids in estimating the altitude. 

The petitioner requests exemption from 14 CFR Part 91.151, Fuel requirements for flight in VFR 

conditions, prior relief has been granted for manned aircraft to operate at less than the prescribed 

minimums, including Exemption Nos. 2689, 5745, and 10650. In addition, similar UAS-specific relief has 

been granted an Exemption Nos. 8811, 10808, and 10673 for daytime, Visual Flight Rules (VFR) 

conditions. The petitioner’s UAS provides low battery warnings that indicate the PIC must command the 

UA’s return to the launch point when low battery capacity voltage is reached. The UAS also provides 2 

and 3rd increased intensity critical low battery warnings through audio and vibration indicating that the 

UA must be landed immediately, additionally a fail safe automatic landing will occur when the battery is 

at absolute critical low voltage. The petitioner warrants that the sUAS will be landed immediately upon

the 1st low battery alert or no longer than 18 minutes which ever occurs first. The petitioner will not 

initiate 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 30% battery power 

remaining.

The petitioner requests exemption from 14 CFR Subpart E (§§ 91.401-417),) Maintenance required, 

91.407(a)(1) Operation after maintenance, preventive maintenance, rebuilding, or alteration, 

591.409(a)(1) and (2) Inspections, and 91.417(a) and (b) Maintenance records. Currently the 

manufacturers maintenance procedures govern preflight with no limits other than on-condition. The 

petitioner will complete all authorized component replacements at the petitioner’s base of operations 

or in the field as required. The manufacturer or authorized repair center will complete any maintenance 

or repairs that cannot be completed by the petitioner. The petitioner warrants that preflight, post flight 

and maintenance procedures set forth in the petitioner’s supplements attached should provide an 

acceptable level of safety for the operations performed and is consistent with those of previous grants. 

In addition the petitioner will comply with any and all manufacturers updates for UAS and Ground 

station as well as any FAA directives and guidelines. An appropriate aircraft/maintenance logbook will 

be kept with the sUAS ground station and base of operations as required, (See Supplement). 

As previously stated the petitioner has demonstrated over 2 years of safe operations in aviation. The 

petitioner requests the administrator to consider that the same standards and safe practices utilized by 

this petitioner would be an asset and greatly benefit the development and integration of the UA system 

into the National Airspace. Furthermore it is of this petitioner’s best interest to insure safe, compliant 

and professional commercial operations for the furtherance of public safety in the aviation industry.

Sincerely,

Calvin Croy Stallings,
