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

Aviation Regulations 

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, Empire Unmanned LLC, seeks an exemption from Federal Aviation 

Regulations (“FARs”) detailed below for the eBee Ag Unmanned Aircraft System manufactured 

by SenseFly SA of Switzerland. This application is identical to the application of Advanced 

Aviation Solutions LLC, to which you granted Exemption 11136 on 5 January, 2015. With 

Advanced Aviation Solutions' cooperation, we have updated the restrictions to match the 

additional restrictions of the Grant 11136. To speed processing, all other requests including 

those that you deemed unnecessary, remain the same.

The requested exemption would support an application for a commercial Certificate of 

Authorization to use the system to support agriculture. The eBee Ag system consists of a 

lightweight (1.5 lb) battery operated aircraft, a PC-based ground control station, and associated 

communications equipment. The aircraft carries an onboard geo-referenced still camera that 

allows it to conduct precision photogrammetry and crop scouting at the resolutions necessary for 

precision agriculture. This high-resolution data can direct variable seeding rates as well as the 

precise application of fertilizer and chemicals reducing their use. This data helps farmers to 

maximize yields while reducing costs and impacts to the environment. By approving these 

exemptions, the FAA will create benefits to both agriculture and the environment which are 

ultimately in the public interest.1 

The aircraft will be operated in the field with both a Pilot in Command (PIC) and a ground-based 

Visual Observer (VO) in accordance with FAA Order 8900.1, vol. 16 "Unmanned Aircraft 

Systems" with the following additional restrictions:

- All operations will occur in Class G airspace at no more than 400' AGL

- Operations will be operated over private property with the permission of the land owner

- All required permits will be obtained from state and local government prior to operation

- The aircraft will not be operated over urban or populated areas

- The aircraft will not be operated at air shows or over an open-air assembly of people

- The aircraft will not be operated over heavily trafficked roads

- The aircraft will not be operated within 5 NM of an airport or heliport

- Operations will be limited to day, visual meteorological conditions

- Aircraft will remain within Visual Line of Sight at no greater than 1/2 NM of the PIC at all time

 

1 We will provide an explanation of equivalent level of safety for each exemption request, but will point back to the 

benefits to agriculture and the environment to justify why the requests are in the public interest.
2 of 6

- While the aircraft is airborne, the VO will be positioned within voice distance to the PIC

- PIC will file a NOTAM providing radial/DME, radius, and a date/time group for each operation

The PIC and VO will meet the requirements outlined in FAA Order 8900.1, volume 16, chapter 4. 

The PIC will hold a Private Pilot's Certificate and current Class III medical. Additionally, the 

PIC will perform maintenance on the system and will complete a course of maintenance 

instruction as part of their initial training. Due to the simplicity of the system, we do not 

anticipate the need for a supplemental pilot.

We submit that the combination of the aircraft's light weight, historically demonstrated flight 

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

8900.1, the FAA can have confidence that the operation will have an equivalent or greater level 

of safety of manned aircraft performing the same mission.

The name and contact information of the applicant are:

EXEMPTION REQUESTS AND EQUIVALENT LEVEL OF SAFETY

Advanced Aviation Solutions requests an exemption from the following regulations as well as 

any additional regulations that may technically apply to the operation of the SenseFly eBee Ag:

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 UAS, we request an experimental 

certificate be issued for the SenseFly eBee Ag 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 fact that the aircraft weighs only 1.5 pounds and is 

constructed primarily out of foam, we propose that the eBee Ag 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 1.5 lbs, the eBee 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: 
Appendix A

Manufacturer: SenseFly SA 

Model: eBee Ag

Serial Number: 14-XXXX

Registered to: 

Advanced Aviation Solutions LLC

8111 Moerkle Street

Anytown, OH 12345

If found please contact: (800)-555-1234.

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 1.5 pound eBee Ag 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" 

on the top of the aircraft, 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 

should it be found on the ground. 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 1/2 NM of the ground station, the banner 

should be visible to anyone that observes the aircraft and chooses to investigate it's 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. 

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

approved Airplane Flight Manual (appendix E) 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 
Appendix A

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

passengers or property for compensation or hire.

Our proposed operations 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 provides that "No person may operate a civil aircraft that is being used for flight 

instruction unless that aircraft has fully functioning dual controls." The eBee ground control 

station is based on a small hand-held computer and while it does not offer a 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 and provides an equivalent level of safety.

14 CFR 91.119 Minimum safe altitudes: General.

The regulation provides 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 400 feet AGL, we cannot comply with this requirement. 

To provide an equivalent level of safety we will only fly over private property with the 

permission of the land owner. The land owner will be briefed of the expected route of flight and 

the associated risks to persons and property on the ground. We maintain that due to the small 

size of the eBee Ag, the hazard to persons, vessels, vehicles, and structures is not comparable to 

manned aircraft and should be considered in granting the exemption. (see appendix C section 

6.4.1 Consideration about risks related to ground impacts) 

The aircraft will not be operated over congested areas nor over any open air assembly of persons. 

The aircraft will be operated at an altitude allowing, if a power unit fails, an emergency landing 

without undue hazard to persons or property on the surface.

14 CFR 91.121 Altimeter settings.

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

setting available within 100 nautical miles of the aircraft. The aircraft will fly below 400 feet 

AGL and will not need to maintain hemispherical cruising altitudes in order to de-conflict with 

other aircraft. As such, an appropriate altimeter measurement presented to the pilot should be 

Above Ground Level and should be based on the barometric pressure at the point of launch. To 

provide an equivalent level of safety, the UAS's AGL altimeter will be set to zero on the ground 

prior to every flight. Since the aircraft will fly no more than 50 minutes, even rapid changes in 

barometric pressure will have limited affect on the safety of the flight.

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 day-VFR 

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 a reserve of 

energy as a safety buffer for go-arounds and other delays to landing.

The eBee Ag is battery operated and the maximum duration of flight from a single battery charge 

is 50 minutes. Since the aircraft will never fly more than 1/2 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, and 

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 attached Maintenance Procedures (appendix D), the PIC will ensure that the 

aircraft is in an airworthy condition prior to flight and conduct detailed inspections after every 10 

hours. Maintenance performed by the PIC is limited to repairing small cracks, replacing a 

propeller, and updating software and firmware. All other maintenance will be performed by the 

manufacturer. 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.
