Subject: Exemption Request under Section 333 of the Federal Aviation Administration Reform Act and Part 11 

of the Federal Aviation Regulations

Dear Sir or Madam:

Pursuant to Section 333 of the Federal Aviation Administration (FAA) Modernization and Reform Act of 2012 

(the “Reform Act”) and Title 14 of the Code of Federal Regulations (CFR) Part 11, Strat Aero International, Inc. 

(“Strat Aero”), a Texas-based business providing aviation consulting, aviation software, and UAS training, seeks 

exemptions for the Federal Aviation Regulations (“FARs”) in order to train Strat Aero UAS operators and to 

provide aerial photography and persistent surveillance of multiple events and facilities. Strat Aero’s limited 

proposed use of sUASs does not create a hazard to the public or other aircraft in the national air space (NAS), 

nor does it threaten national security. The small size, low speed, and safety features of the sUASs to be used

and operating distance from populated areas ensure the proposed operations would be safer than conducting 

the same operations with manned aircraft and as such is in the best interest of the public. Strat Aero’s 

proposed use of sUASs addresses criteria identified in the FAA’s exemptions granted to Commonwealth Edison

(Exemption No. 11185), BNSF Railway Company (Exemption No. 11206), Phoenix Air Unmanned (Exemption 

No. 11241), State Farm Mutual Automobile Insurance Company (Exemption No. 11188) and the City of Roswell 

Coalition (Exemption No. 11265). Please note that Strat Aero is the operator for the City of Roswell Coalition as 

described in the City of Roswell Coalition Exemption, and whenever possible, Strat Aero operations will be 

similar to those approved the same exemption (No. 11265).

The requested exemptions would permit Strat Aero to conduct operations with the Aerialtronics Altura Zenith

ATX8, the STR8 (an octocopter with operational characteristics similar to the Ascending Technologies Falcon 8

sUAS), the Aeryon Labs SkyRanger, and/or the DJI S1000 for various purposes (please refer to section 6 for a 

detailed list.

Strat Aero would issue a NOTAM to Air Traffic Control in the area and follow all safety protocols to inspect 

these facilities with sUASs. Strat Aero believes using sUASs responsibly to conduct these types of inspections is 

immensely safer than having personnel or manned aircraft conduct the same inspections.

The aerial data provided by a UAS will improve the ability of customer companies to assess the condition and 

safety of their equipment in a timely manner, thereby enhancing safety for customer companies and for their 

customer bases.

Strat Aero UAS flying operations under the exemption will be conducted according to strict standard operating 

procedures and safety guidelines as set forth by the operator and as may be modified by the FAA. Any sUAS 

system operated by Strat Aero will be flown under controlled conditions by qualified operators. It will be flown 

at low altitudes in airspace that are limited in scope with the exception of industrial inspections as described in 

section 7 below and only under strict conditions. Strat Aero operations with these sUASs will not be conducted 

in a way that violates established industry privacy guidelines or reasonable expectations of privacy.

Regarding the Unmanned Aircraft System

1. Safety

Characteristics of the Aerialtronics Altura Zenith

The Altura Zenith ATX8 is an octocopter that can be flown with a tablet or radio controls and can carry a 

wide array of sensors. The Zenith has a maximum takeoff weight of 8.5 kg (18 lbs) and measures 23.6 

inches square. It can fly for up to 35 minutes at a time and has a maximum cruise speed of 20 m/s (40 kts). 

This sUAS has software that allows for automatic take-off and landing, automatic fly home and landing, GPS 

waypoint navigation, direction lock, and geographic information system (GIS) mapping. The FAA has 

previously granted exemptions for this model UAS.

Characteristics of the STR8

The STR8 sUAS consists of an unmanned vehicle, a remote control, and a mobile ground station. The aerial 

vehicle consists of a small V-form rotorcraft lifted and propelled by eight rotors. It is electrically powered 

by lithium power and therefore presents no fuel spill risk. The STR8 has enhanced safety features including 

constant self-monitoring, resistance to external magnetic disturbances, two independent data links, three 

emergency modes, and battery life monitoring. Each of these features help mitigate the risks inherent in 

flying. 

The aerial vehicle can hold a pre-planned position. All systems monitor their operational status and battery 

life. An enhanced contingency detection system automatically notifies the pilot when error statuses are 

detected. There are three emergency modes from which the pilot can choose should the data links be lost 

– the pilot can direct an immediate landing or that the system return to base at its current height or at 

maximum mission height (whichever is the safest option).

Airworthiness of the Aeryon SkyRanger 

The Aeryon SkyRanger provides two semiautonomous flight modes using a point-and-click map and video 

interface. The user clicks on a map to direct the SkyRanger to fly to the point on the map where the 

operator is pointing, or programmed flight plans may be entered for a series of waypoints or grid-based

area. Additional navigation aids including landing zones and flight areas may be designated to ensure the 

SkyRanger operates only within user-specified flight parameters (geo-fencing). All flight operations are GPS 

controlled making the system easy to navigate, and the flight control system also employs a variety of 

sensors including sonar, barometric pressure, temperature, wind speed and others to ensure the high 

stability and reliability in challenging weather conditions. During flight operations, the operator can 

intervene with a programmed flight and take immediate control. The SkyRanger also has a significant set of 

automated features to ensure safe takeoff, flight and landing in many conditions, further details of 

operation can be found in Attachment 3. 

As a result of the considerable number of safety features identified above, the SkyRanger has received 

multiple approvals for previous operations. Aeryon Labs believes it has shown compliance through its 

history of successful flight operations which include cooperation with several public agencies. The list of

organizations who have used SkyRanger includes: Michigan State Police, US Navy SPAWAR, Mass 

Development (Joint Base Cape Cod), Unmanned Experts (NIJ Partnership), Western Washington University, 

Aetos (via Northwest Michigan College), University of Alaska Fairbanks, University of New Mexico, Kansas 

State University, and Virginia Tech University. The SkyRanger has also successfully completed the

Department of Homeland Security RAPS Trial in 2013. In Canada, Aeryon has obtained 19 Special Flight 

Operations Certificates (SFOCs) from Transport Canada over 5 years and its customers have received 

multiple certificates to perform demonstration, research and development, public and commercial 

operations. The criteria set forth in the certificates granted specify the substantive showings of the device’s 

safety and fitness for operation to ensure that the FAA has sufficient basis to evaluate the aircraft’s safety. 

Airworthiness of the DJI Spreading Wings S1000 

The DJI S1000 has been approved in over 20 granted Section 333 exemptions to date. This is an octocopter 

with a maximum takeoff weight of 11 kg (24 lbs.) and a 15 minute flight time. The S1000 has numerous

built-in safety measures. It can adjust automatically should an engine fail and alerts the PIC to the 

possibility of a lost link before it occurs. If the control link is broken, the UAS will return to a preprogrammed location for landing. 

2. Procedures Ensuring UAS in Condition for Safe Flight

The pilot will manually inspect the sUAS according to manufacturer’s instructions prior to each operation 

(refer to page 11 in Attachment 2 for the STR8, page 20 in Attachment 3 for the SkyRanger, and page 5 in 

Attachment 4 for the DJI S1000). The PIC will ensure all visible parts are in good working condition, a good

signal connection exists between the device used to operate the system and the vehicle itself, and will run 

any available diagnostics to further ascertain the overall status of the sUAS.

Risk to National Airspace System (NAS)

Strat Aero will issue a NOTAM no later than 24 hours prior to any operation, and will notify any 

additional applicable agencies to enhance traffic de-confliction and safe operation in airspace. When 

authorized for flying above the FAA blanket AGL altitude, Strat Aero will remain within a 50 foot radius 

(horizontally and/or vertically) of any protruding structure that is the object of our inspection. These 

structures have been previously identified by the FAA on aeronautical charts. In consideration of the 50 

foot radius limitation, the risk of interference with another aircraft is minimal. 

The risk posed by using manned aircraft to conduct these operations is higher than with sUASs, and in 

some cases manned aircraft cannot duplicate the UAV capabilities. These smaller, lightweight 

unmanned systems have much less kinetic energy than higher mass manned aircraft, thus much less 

impact effect. Also, they do not carry fuel and as such do not pose the explosion hazard compared to 

manned aircraft.

Risk to Persons and Property on the Ground

Each of the four sUAS’s Strat Aero requests to use commercially has software-based fail-safes that 

minimize the risk of catastrophic system failure. When these features are coupled with the strict safety 

procedures to which Strat Aero operators will adhere, Strat Aero sUAS operations will achieve at least 

an equivalent level of safety to those achieved in manned aircraft operations. For inspection 

operations, these areas are often access-controlled by the company and/or individuals owning the 

structures, further ensuring safety of the operational area and reducing risk to people and property.

Please reference attachments to further review operational characteristics of these systems.

Regarding the Unmanned Aircraft PIC

4. Qualifications Required of PIC(s)

Strat Aero PICs will comply with FAA minimum guidelines for sUAS pilot certification and training standards. 

The current minimum requirement is to possess a sport pilot’s license. In addition, Strat Aero will ensure 

that pilots complete manufacturer and company-developed training and will also require currency training 

at regular intervals. 

5. Medical Standards and Certification of the PIC

Per guidance in Exemption No. 11265, at a minimum, the PIC and VO will each 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.

Regarding the Operation of Unmanned Aircraft

6. Intended UAS Operation(s)

Strat Aero proposed operations include but are not limited to:

 Utility infrastructure monitoring and inspection (e.g. electricity generation facilities (wind, water, 

solar, gas, and coal), water management, and gas and oil production and transportation facilities); 

 UAS operator training and curriculum development; 

 Contingency site surveillance for emergency management; 

 Aerial mapping and surveying; 

 Wildlife monitoring; mining, forestry, and other agricultural applications; 

 Transportation analytics;

 Intelligence, surveillance, and reconnaissance support to commercial and governmental agencies (to 

include military and/or law enforcement/EMS applications); 

 Still photography; 

 And aerial data collection to aid in research and development initiatives. 

7. Proposed Flight Parameters

Strat Aero expects to be subject to the following mandatory conditions contained in similar recent 

exemptions:

 Operations to be conducted over private or controlled access property.

 Permission from land owner/controller required before commencing any flight.

 Operations to occur during Visual Flight Rules Meteorological Conditions (VMC).

LONDON NEW YORK HOUSTON DENVER SEATTLE SINGAPORE DUBAI

 Aircraft to remain within Visual Line of Sight (VLOS).

 Operations to occur during daylight hours.

 Above Ground Level (AGL) altitude to be restricted to 400 feet with the possible exception of certain 

industrial inspections as described below.

 All operations conducted in vicinity of airport to remain within the boundaries of the authorized

location and so as to adhere to any conditions set forth in that authorization.

 Operator will file a NOTAM and/or notify ATC prior to each flight per conditions of authorization.

 All required permissions and permits will be obtained from territorial, state, county or city

jurisdictions, including local law enforcement, fire, or other appropriate governmental agencies.

 All operations will include one pilot for flight control and one observer for VLOS enhancement.

The requested exemption would especially assist with inspections of industrial and utility infrastructure that 

can be dangerous and difficult to conduct either manually or with manned aircraft. Strat Aero requests 

permission to inspect those types of structures that extend above 200 feet above ground level (AGL).1 

Standard operating procedures would be adhered to that restrict any exceedance of 200 feet AGL to 

inspection activities within a radius of 50 feet of the structure being inspected. A greater than equivalent 

level of safety would be achieved by the PIC/Observer focused on inspection activities and avoiding UAV 

contact with the nearby structure beyond that achieved now using helicopters or people to conduct these 

inspections. Per the OSHA website, there were 11 fatalities in 2014 and 13 fatalities in 2013 attributed to 

accidents on or near communications towers. 2 

 Some example structure types follow:

o Wind turbines – Up to 540 ft. altitude (495 turbine height plus 50 feet maximum vertical 

allowance). Per the 2011 Wind Energy Industry Manufacturing Supplier Handbook, some wind 

turbine towers are as tall as 330 feet, and blades can be as large as 165 feet. 3 If power to the 

turbine is shut down (as would be the case in preparation for inspection), a blade could come to 

rest in its apex position, rendering the maximum height of the entire structure 495 feet.

o Radio, television, and cell phone communications towers.

8. Area of Intended Operation(s)

Strat Aero customers and corporate partners are dispersed throughout the United States. As such, Strat Aero 

requests that approval be granted nationwide. Strat Aero will comply with all notice filing and any other 

operational requirements specified by the FAA. Strat-Aero will describe a finite and limited area of operation

for each mission. Any structure to be inspected that protrudes above the 200’AGL plane will be

specifically identified. All other flight activity will be conducted below the FAA specified blanket altitude, 

including transit between take-off/landing spot and the target of our inspection. Such structures have 

already been identified and met FAA criteria. Staying within a 50’ radius of these structures should not 

present a measureable increase of risk nor jeopardize the safety of the public.

9. Proximity to Airports

Strat Aero will adhere to FAA-issued restrictions with regards to flying in close proximity to airports. The 

company will not operate sUASs within:

 5 nautical miles (NM) from an airport having an operational control tower; or 

 3 NM from an airport having a published instrument flight procedure, but not having an operational 

control tower; or 

 2 NM from an airport not having a published instrument flight procedure or an operational control 

tower; or 

 2 NM from a heliport 

unless a letter of agreement with that facility’s management is obtained or otherwise permitted by a COA 

issued to the exemption holder. The letter of agreement with the facility or airport management must be 

made available to the Administrator or any law enforcement official upon request.

10. Compliance with VLOS Requirement

Both the PIC and VO will ensure operations are conducted within VLOS only. The PIC and VO will use 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.

11. Pre-flight Safety Risk Assessment

PIC and VO will conduct a thorough visual sweep of the area of intended operations and a safety briefing 

before commencing operations. In addition, PIC will ensure all manufacturer and Strat Aero pre-flight 

inspection procedures are complete including pre-set of minimum and maximum altitudes (see user 

manuals for specific checklists). 

12. Coordination with Flight Standards District Offices (FSDOs)

Strat Aero will coordinate our flight activities with the local FSDO as required and will submit monthly flight 

reports as directed.

Exemptions Sought

Section No. (§) Description Reasoning and/or Mitigation

14 CFR Part 21 

& 14 CFR 

§91.203 (a)

Airworthiness Certificates Given the size of the aircraft (6 lbs.) and the limited 

operating area associated with its utilization, it is 

unnecessary to go through the certificate of airworthiness 

process under Part 21 Subpart H to achieve or exceed 

current safety levels. It will not carry a pilot or passenger, 

will not carry flammable fuel, and will operate exclusively 

within an area pre-disclosed and in compliance with 

conditions set forth herein. Operations under this 

exemption will be tightly controlled and monitored by both 

the operator, pursuant to the conditions set forth above, and 

by local public safety requirements. The FAA will have 

advance notice of all operations through the filing of 

NOTAMs. Receipt of the prior permission of the land owner, 

the size of the aircraft, the lack of flammable fuel, and the 

fact that the aircraft is carried to the location and not flown 

there all establish the equivalent level of safety.

14 CFR §61.23 Medical certificates: 

Requirement and duration

Per previously-granted exemptions, both the PIC and VO will 

possess a valid U.S. driver’s license issued by a state, 

territory, or the federal government. Medical certification 

should not be required as these sUASs are lightweight, not 

manned, do not carry liquid fuel, and have built-in software

ensuring automatic responses to potential safety issues. In 

addition, to further mitigate safety concerns, the on-site lead 

will pre-brief personnel on safety procedures, and any 

personnel can initiate the cessation of operations for any 

safety-related reason.

14 CFR §61.101 Recreational pilot 

privileges and limitations

The PIC will undergo manufacturer and company-specific 

training in order to achieve a level of safety at least

Strat Aero operators will be trained with manufacturerdeveloped and company specific training that will provide 

adequate safety training. Completion of this training and 

adherence to Strat Aero SOPs and manufacturer guidelines

will guarantee a level of safety equivalent to those required 

of larger manned aircraft.

14 CFR §61.315 Sport pilot privileges and 

limitations

The PIC will undergo manufacturer and Strat Aero-specific 

training in order to achieve a level of safety at least 

equivalent to that of a pilot with a sport license operating 

manned aircraft pursuant to this section. Strat Aero requests 

an exemption to this section based on the similarities of our 

petition with that of the reliefs granted under Exemption 

Nos. 11241 and 11265.

14 CFR §91.7 

(a)

Civil aircraft airworthiness The PIC will comply with standards outlined in the 

appropriate operator’s manual to ensure the rotorcraft is in 

an airworthy condition prior to every operation. Pre-flight 

inspections will ensure the craft is safe for operating and will 

meet the intent of this section without requiring a certificate.

14 CFR §91.9

(b) (2) & (c)

Civil Aircraft Fight Manual 

in the Aircraft

sUAS vehicles cannot carry a manual due to their small size, 

but a manual will be available at the ground control station 

where the pilot flying the sUAS will have immediate access to 

it. The FAA has granted this to others in the following 

exemptions: 8607, 8737, 8738, 9299, 9565, 10167, 10602, 

10700, and 11265.

14 CFR §91.103 

(b) (2)

Pre-flight action While the FAA has not approved a flight manual for 

rotorcraft, the PIC will achieve an equivalent level of safety 

by following the manufacturer’s pre-flight checklists. 

Reference page numbers described in section 2 for these 

checklists.

14 CFR §91.105 Flight crewmembers at

and per the operating instructions set forth in the 

manufacturer’s guidance. 

14 CFR §91.119 

(b) and (c)

Minimum safe altitudes The sUAS will remain below 400 feet above ground level 

(AGL) at all times unless during brief periods of industrial 

inspections as described on page 4 of this exemption request 

letter. The PIC will ensure the sUAS is flown in accordance 

with manufacturer’s safety guidelines and in such a way that

achieves a level of safety equivalent to those allowed for 

helicopters operating at similar altitudes. 

14 CFR §91.121 Altimeter settings The above-referenced sUASs do not have a traditional 

altimeter. The onboard data systems monitor altitude, all 

flight data is monitored by the operator, and readings are 

stored on an SD card onboard. All operations will be 

conducted within line of sight, out of the airspace used by 

most manned aircraft, and below 400 feet AGL.

14 CFR §91.151 Fuel requirements for 

flights in VFR conditions

Each of the sUASs identified in this petition indicate low 

power status to the pilot when there is still sufficient power 

to conduct a safe landing (up to five minutes left in battery

power). Warnings continue and increase in intensity and 

frequency after the first indication of the battery charge 

being low.

14 CFR §91.203

(a) & (b)

Civil aircraft: Certifications 

required

The request for exemption from 14 CFR §91.203 (a) is 

coupled with the request for relief from 14 CFR Part 21 (see 

top of page 5). With regards to §91.203 (b), the sUASs are 

too small to carry COAs onboard, but the document(s) will be 

available at the ground station. This will ensure the pilot has 

access to these documents at all time.

14 CFR §91.405 Maintenance required The PIC will conduct pre-flight checks to include any visible 

need for maintenance prior to operations. If a problem is 

present but not visible to the pilot, the issue will still be 

corrected – both sUASs notify the PIC of maintenance issues 

on startup and continue to monitor status after takeoff. 

When the PIC or other qualified maintainer is alerted to 

maintenance issues, he or she will conduct maintenance as 

directed in the sUAS-specific operating manual. Strat Aero 

will also ensure the systems are periodically inspected for 

any issues to further prevent in-flight errors or failures. A 

maintenance log will be maintained for reference and will be 

available to regulatory officials upon request.

14 CFR §91.407 Operation after 

maintenance

checklists, the PIC or other trained technician is qualified to 

ascertain the suitability of the sUAS for continued 

operations. 

14 CFR §91.409 Inspections Inspections will be conducted before and after each flight as 

well as at periodic intervals. These regular inspections 

ensure a level of safety equivalent to that of inspecting 

manned aircraft annually is achieved. 

14 CFR §91.417

(a) and (b)

Conclusion

The planned uses for the Aerialtronics Altura Zenith ATX8, STR8, Aeryon SkyRanger, and DJI S1000 systems

satisfy the criteria set forth in Section 333 of the Reform Act. Strat Aero’s proposed sUAS operations, subject 

to the conditions listed above, do not create a hazard to users of the national air space (NAS) or the public or 

threaten national security. The small size, low weight, low speed, safety features, and operating distance from 

airports and populated areas mitigate these safety issues. 

The operation of the sUAS for aerial data collection in accordance with the strict conditions outlined herein will 

provide more than an equivalent level of safety, supporting the grant of the exemptions requested. Approval of 

the exemptions allowing operations of the aforementioned systems for aerial photography and surveillance will 

enhance safety by reducing the risks inherent in the same services when conducted manually or with manned 

aircraft. Other aerial inspection options available to Strat Aero customers using conventional rotary aircraft, 

present risks associated with vehicles that often weigh several thousand pounds and carry large quantities of 

fuel, passengers, and cargo. Such aircraft must fly to and from the inspection locations. While these sUASs will 

operate at similar speeds and altitudes of manned aircraft, the heaviest weighs approximately 6 pounds (89% 

less weight than the 55 pound maximum established by the FAA), is powered by batteries, and will be carried 

to the inspection location. The sUASs will not fly over residences and will not expose any individuals to the 

risks associated with manned aircraft flights. All of these factors greatly reduce the risks associated with 

conventional operations. 

Given their reduced size, speed, load capacity, and lack of fuel spill risk, the Aerialtronics Altura Zenith ATX8, 

DJI S1000, STR8, and Aeryon SkyRanger sUASs pose no threat to national security. Further, the operating 

capabilities, avoidance of airspace used by other aircraft, operation within visual line of sight, and use of 

licensed pilots provide adequate justification to grant the requested exemptions.
