Re: Exemption Request under Section 333 of the FAA Reform Act and Part 11 of the 

Federal Aviation Regulations. Document ID: FAA-2007-0001-0001

Dear Sir or Madam:

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

“Reform Act”) and 14 C.F.R. Part 11, Enda Cusack seeks an exemption from Federal 

Aviation Regulations (“FARs”) detailed below for the following described Unmanned 

Aerial System called in this application the DJI Inspire 1, which includes an 

Unmanned Aircraft (UA) and ground station-based equipment and crew:

THE UNMANNED AIRCRAFT (UA):

DJI Inspire 1: See enclosed DJI Inspire 1 Manual. The inherent safety features, 

sophistication, programmability, GPS navigation, return home capability, airport 

vicinity no-fly feature and restricted altitude feature, as well as differentiating radio 

frequency (rf) for aircraft controller/receiver and for the camera make this a much 

safer UAV for the purposes of this petition. This is a hobby grade radio controlled 

UAV that has the capacity for software upgrades. It is light, less than 7 pounds 

including battery and camera. Incorporated into the programming of the Inspire1 is 

an automatic return home feature that automatically directs the craft back to point 

of take off should communication with the transmitter be lost. The Inspire1 has a 

maximum speed of 49 miles/hour. Maximum flight time is 18 minutes. Gross weight 

is 6.5 pounds.

The Inspire1 has an additional communication link between the camera and craft on 

a different rf for a smart phone connection. Allowing the operator or Pilot In 

Command (PIC) to monitor battery level, altitude (AGL), distance from PIC, camera 

imagery, and control camera angle. 

The software for the Inspire1 allows the operator or PIC to set maximum altitude AGL 

for each flight, allowing customization of flights to no higher than 150 feet can be 

programmed into the UAV's software pre-flight to insure compliance with FAA 

standards. Adding to the safety capabilities of this UAV. This UAV is programmed to 

remain in position when controls are released. Maintaining altitude and GPS location. 

The Inspire1 has an altitude and radar monitoring function that allows the operator 

more precise determination of height, direction of flight and distance from the 

operator PIC. The operator or PIC can monitor GPS lock status while UAV is in flight, 

with the ability to anticipate loss of GPS locking so the operator or PIC can land the 

UAV as a precaution. The inspire1 is also equipped with a new safe dynamic return to 
home function and automatic safe landing and taking off modes. The intelligent 

battery also calculates how much power is needed to safely return home.

The requested exemption would support an application for a commercial Certificate 

of Authorization to use the above described CAV System to support aerial 

photography and video primarily of real property, specifically individual properties of 

at least two acres in size (equivalent to a square 295 feet/side).

The UA, powered by batteries, is smaller, lighter and more maneuverable than larger 

aircraft running on combustible fuel, it operates at lower altitudes with no people on 

board and will thereby reduce current risk levels and thereby enhance safety and 

diminish the likelihood of death or serious bodily injury. With a small payload and 

maximum flight time of only 15 minutes, this is offers little or no risk to national 

security.

Low level oblique photos and video from several angles are far more effective than 

ground-based imagery for displaying the characteristics of large, complex properties 

with several buildings and large trees. The applicants in the past have chartered 2-

seat full-sized helicopters for this purpose, which has proven more costly than many 

potential clients have been able to afford. The benefits of reduced cost and improved 

quality of presentation from the UA will be valuable to and benefit many buyers and 

sellers of real property.

Additionally, we request that we be allowed to use our system to benefit first 

responders nearby who might require assistance, including fire fighters, the police, 

the sheriff, et al., while remaining subject to all limitations cited in this application as 

we do so.

The Inspire 1 will be operated in the field with both a PIC and a Visual Observer in 

accordance with FAA Policy N 8900.227 Section 14 "Operational Requirements for 

UAS" and with the following Restrictions:

(a) No flight will be made with a UA Gross weight exceeding 55 pounds;

(b) All operations must occur in FAA Class G airspace at no more than 400 ft 

AGL, at an airspeed of no more than 25 knots and no further than 3/4 NM 

from the PIC;

(c) (All operations must utilize a visual observer (VO). The VO and PIC must be 

able to communicate by voice at all times during a flight operation;

(d) Operations will be restricted to flights over private property with the 

permission of the property owner;

(e) The PIC must have accumulated and logged, in a manner consistent with 14 

CFR § 61.51 (b), a minimum of 100 flight cycles and 25 hours of total time as 

a UA rotorcraft pilot and at least ten hours logged as a UA pilot with a similar 

UA type;

(f) All required permits will be obtained from state and local government prior to 

operation;

(g) The Inspire1 will not be operated over densely populated areas;

(h) The Inspire1 will not be operated at air shows;

(i) The Inspire1 will not be operated over any open-air assembly of people;

(j) The Inspire1 will not be operated over heavily trafficked roads;

(k) The Inspire1 will not be operated within 5 NM of an airport or heliport;

(l) Inspire1 will not be operated over properties smaller than two acres in size;

(m)Operations will be restricted to day only and weather conditions equivalent to 

VFR;

(n) The PIC will brief the VO and property owner about the operation and risk 

before the first flight at each new location;
(o) No flight may be made without a Pre-Flight Inspection by the PIC before each 

operation to ascertain that the UA is in a condition safe for flight (see 

Appendix A).

The PIC and VO will meet the requirements outlined in FAA Policy N 8900.227 

Section 16 personnel Qualifications. Additionally, the PIC and VO will perform 

maintenance on the system and will complete a course of maintenance instruction 

as part of their initial training.

We submit that the combination of the UA's light weight, flight performance and 

ability, fully qualified flight crew and strict operation under the guidelines established 

in 8900.227, and under all of the Restrictions (a) through (o) listed above, the FAA 

can have full confidence that the operation will have an equivalent or greater level of 

safety than manned aircraft performing the same mission.

ADDENDUM 

EXEMPTION REQUESTS AND EQUIVALENT LEVEL OF SAFETY 

(QGDCXVDFN requests an exemption from the following regulations as well as any 

additional regulations that may technically apply to the operation of the ,QVSLUH

14 CFR Part 21, Subpart H: Airworthiness Certificates 

This part establishes the procedures for the issuance of an airworthiness certificate. While the 

FAA continues to work to develop airworthiness standards for Unmanned Aerial Systems, we 

request an experimental certificate be issued for the ,QVSLUH under either or both of the 

following provisions: 

21.191 Experimental certificates. 

Experimental certificates are issued for the following purposes: 

(a) Research and development. Testing new aircraft design concepts, new aircraft equipment, 

new aircraft installations, new aircraft operating techniques, or new uses for aircraft. 

(b) Showing compliance with regulations. Conducting flight tests and other operations to show 

compliance with the airworthiness regulations including flights to show compliance for issuance 

of type and supplemental type certificates, flights to substantiate major design changes, and 

flights to show compliance with the function and reliability requirements of the regulations. 

Since the experimental certificate can be used for commercial purposes such as market surveys, 

sales demonstrations, and customer crew training, we would expect that an experimental 

certificate would permit our commercial purpose as well. 

The aircraft will not carry persons or property, will not carry fuel, and will only fly under strict 

operational requirements. Combined with the UA’s light weight, being constructed primarily of 

carbon fiber and plastic, we propose that the UA will be at least as safe, if not safer, than a 

conventionally certificated aircraft performing the same mission. 

If an experimental airworthiness certificate is not appropriate for this application, then we 

request an exemption of 14 CFR Part 21, Subpart H, and the requirement for an airworthiness 

certificate in general, citing the equivalent level of safety outlined in the previous paragraph. 

14 CFR 91.203(a) & (b) Civil aircraft: Certifications required. 

The regulation provides that an airworthiness certificate, with the registration number assigned to 

the aircraft and a registration certificate must be aboard the aircraft. Additionally, subparagraph 

(b) provides that the airworthiness certificate be "displayed at the cabin or cockpit entrance so 

that it is legible to passengers or crew." 

At a maximum gross weight of  pounds, the UA is too small to carry documentation, does not 

have an entrance, and is not capable of carrying passengers or crew. To obtain an equivalent 

level of safety and meet the intent of 91.203, we propose that documents deemed appropriate for 

this aircraft by the FAA will be co-located with the crew at the ground control station and 

available for inspection upon request. In order to identify the aircraft, we propose that the 

information found on airworthiness and registration certificates be permanently affixed to the 

aircraft via placard containing the following information plus the word “EXPERIMENTAL” to 
Addendum Page 2 of 4

satisfy the requirement of 14 CFR 45.23, which follows immediately after the proposed placard 

description below: 

EXPERIMENTAL 

Manufacturer: DJI Innovations, Inc.

Model: 70, Serial Number: :'&%

If found please contact: () 

14 CFR 45.23 Display of marks; general and 45.29 Size of marks. 

These regulations provide that each aircraft must display "N" and the aircraft's registration 

number in letters at least 3 inches high. Additionally, the aircraft must display the word 

"EXPERIMENTAL" in letters at least 2 inches high near the entrance to the cabin, cockpit, or 

pilot station. The UA does not have an entrance in which the word "EXPERIMENTAL" can be 

placed, and may not have a registration number assigned to it by the FAA. 

We propose to achieve an equivalent level of safety by including the word "EXPERIMENTAL" 

in the placard on the top of the aircraft, as shown above, where the PIC, VO and others in the 

vicinity of the aircraft while it is preparing for launch will be able to see the designation. 

Additionally, we feel that the permanent placard discussed in the previous paragraph will provide 

the aircraft's registration information at the ground station. Finally, we will display at the ground 

station a high contrast flag or banner that contains the words "Unmanned Aircraft Ground 

Station" in letters 3 inches high or greater. Since the aircraft will operate within 3/4 NM of the 

ground station, the banner should be visible to anyone that observes the aircraft and chooses to 

investigate its point of origin. 

14 CFR 91.9 Civil aircraft flight manual, marking, and placard requirements. 

This regulation provides that no person may operate an aircraft unless a current, approved flight 

manual is in the aircraft. We assume that the intent of this requirement is to ensure that flight 

manual information is available to the aircrew while operating the aircraft. We request an 

exemption to this requirement since the aircraft is not only too small to carry documentation, the 

documentation would not be available to the crew during flight operations. 

 

To obtain an equivalent level of safety and meet the intent of 91.9, we propose that a current, 

approved UA Flight Manual (Appendix A) must be available to the crew at the ground station 

anytime the aircraft is in, or preparing for, flight. 

14 CFR 61.113 Private pilot privileges and limitations: Pilot in Command and 61.133 

Commercial pilot privileges and limitations. 

The regulation provides that no person that holds a private pilot certificate may act as pilot in 

command of an aircraft for compensation or hire. Subparagraph (b) allows a private pilot to act 

as pilot in command of an aircraft in connection with any business or employment if: (1) The 

flight is only incidental to that business or employment; and (2) The aircraft does not carry 

passengers or property for compensation or hire. 
Addendum Page 3 of 4

Our proposed operations require that the PIC must either 

1. Hold a Commercial Pilot Certificate issued by the FAA, and have logged 25 hours of flight 

experience in this type of UA, or 

2. Meet the requirements of 8900.227 para 16(c)(2)(c) "Operations without a pilot certificate" 

in which the PIC is required to complete "FAA private pilot ground instruction" and pass 

"the FAA Private Pilot written examination." Since there are currently no means available 

for the pilot of a UAS to gain the experience in an equivalent category and class in order to 

apply for a commercial pilot's license, we propose to generate an equivalent level of safety 

by requiring our pilots to complete, at a minimum, FAA commercial pilot ground 

instruction and pass the FAA Commercial Pilot written examination in addition to 

completing the private pilot requirements. Since the aircraft cannot carry passengers or 

property, we feel we meet the intent of 61.113 Subparagraph (b) even though the intent of 

this application is to conduct a business. 

14 CFR 91.109 Flight Instruction; Simulated instrument flight and certain flight tests 

The regulation states that "No person may operate a civil aircraft that is being used for flight 

instruction unless that aircraft has fully functioning dual controls." 

The ,QVSLUH ground-based control station consists of a small hand-held radio transmitter 

andD second set of "controls", both the student and instructor can, and will, operate the single set 

of controls simultaneously. With both student and instructor having "hands-on" the controls during 

flight, we feel that this technique meets the intent 91.109 anGSURYLGHVDQHTXLYDOHQWOHYHORIVDIHW\

7KHGXDOFRQWUROVDOORZDSLORWWRIO\DQGD92WRFRQWUROWKHFDPHUDIXQFWLRQV

14 CFR 91.119 Minimum safe altitudes: General. 

The regulation states that over sparsely populated areas the aircraft cannot be operated closer 

than 500 feet to any person, vessel, vehicle, or structure. Since the aircraft will be operating at a 

maximum of 0 feet AGL, we cannot comply with this requirement. 

In order to provide an equivalent level of safety we will only fly over private property with a size 

of at least two acres with the permission of the owner of the property flown over. The aircraft 

will not be operated over congested areas or over any open air assembly of persons. The property 

owner will be briefed on the expected route of flight and the associated risks to persons and 

property on the ground. The aircraft will be operated at a low altitude allowing, if a power unit 

fails, an emergency landing without undue hazard to persons or property on the surface. 

Therefore we maintain that due to the small size of the UA, the hazard to persons, vehicles and 

structures is minimal compared to manned aircraft, which should be considered in granting the 

exemption.

14 CFR 91.121 Altimeter settings. 

The regulation requires that aircraft shall maintain cruising altitudes by reference to an altimeter 

setting available within 100 NM of the aircraft. 

The UA will always fly below 00 feet AGL and will not need to maintain cruising altitudes in 

order to prevent conflict with other aircraft. An Above Ground Level altimeter measurement 

above the takeoff point is transmitted via radio from the UA on-board computer to the display 

screen held by the PIC, providing a constantly updated AGL readout. 
14 CFR 91.151 Fuel requirements for flight in VFR conditions.

The regulation provides that no person may begin a flight in an airplane under dayVFR conditions unless there is enough fuel to fly to the first point of intended landing 

and to fly after that for at least 30 minutes.

We feel the intention of this paragraph is to provide an energy reserve as a safety 

buffer for delays to landing. The UA is battery operated and the maximum duration 

of flight from a single battery charge is 12 minutes with a 20% reserve. Since the 

aircraft will never fly more than 3/4 NM from the point of intended landing, a full 

battery charge at launch will ensure that we meet the reserve energy requirement of 

this paragraph. We request an exemption to the word "fuel" and ask for an equivalent 

interpretation with the word "energy".

14 CFR Subpart E (91.401 - 91.417) - Maintenance, Preventive Maintenance, 

Alterations

The regulation provides that the operator is primarily responsible for maintaining the 

aircraft in an airworthy condition, including compliance with part 39 and 43. 

Paragraphs 91.407 and 91.409 require that the aircraft be "approved for return to 

service by a person authorized under 43.7" after maintenance and inspection.

It is our intention that the PIC perform maintenance and inspection of the aircraft 

and "be authorized to approve the aircraft for return to service." As provided in the 

Pre-Flight Checklist in Appendix A, the PIC will ensure that the aircraft is in an 

airworthy condition prior to every flight and in addition conduct detailed inspections 

after every two hours of flight. Maintenance performed by the PIC is limited to 

repairing small cracks, replacing a propeller, checking electrical connections and 

updating software and firmware for the on-board computer. All other maintenance 

will be performed by the manufacturer or their designated repair facility. The PIC will 

document work performed in accordance with 91.417. We feel that due to the size, 

construction, and simplicity of the aircraft, the PIC can ensure an equivalent level of 

safety.

8900.227 Paragraph 16(c)(4) PIC Medical. and Paragraph 16(e)(1) Observer 

Medical.

This policy provides that both the PIC and VO must have a valid FAA second-class 

medical certificate issued under part 67 in order to perform as a pilot or observer.

The UA maximum gross weight is 6.5 pounds, it is constructed of carbon fiber and 

plastic and the PIC is not on board. Both the PIC and the VO are required to be in 

VLOS. Given the unlikely event that both the PIC and VO become medically 

incapacitated while the aircraft is in flight, the UA will return autonomously to the 

site of launching and land without crew intervention. Therefore, requiring the PIC 

and VO to meet the same medical requirements as a commercial pilot carrying 

passengers in a large aircraft is an unnecessary burden.

We propose that the minimum medical requirements for the PIC and VO be vision 

corrected to 20/20 (with the use of prescription glasses) and a valid, state issued 

driver's license. The 20/20 vision requirement will ensure that the PIC and VO can 

see and avoid air traffic; a licensed driver is medically qualified to operate a much 

larger vehicle.
