III. T he E xtent and the R eason s VERDANT ALPHA S eeks the R elief

The FAA has previously granted material relief from all sections requested in

circumstances similar to those presented herein (e.g. Exemption Nos. 11062, 11063, 11064, 11065, 11066, 11067, 11080, 11109, 11112, 11136, 11138, 11150, 11153, 11156, 11157, 1115 8, 11159, 11160, 11161, 11166, 11167, 11170, 11171).

The FAA has previously granted exemptions from all request ed UAS systems:

 Delair

- Tech DT

- 18 ( Exemption No.11524)6  C

- Astral BRAMOR rTK and gEO platforms (previously granted exemption in
No. 11895 )

 Sensefly eBee ( Exemption No.12785)

 Agribotix Hornet ( Exemption No. 12098 )

 3DR Aero

- M ( Exemption No.12785)

 3DR X8

- M ( Exemption No.12785)

A. 

### Section 91.7(a) Civil Aircraft Worthiness

Relief from § 91. 7(a) is necessary for the operation of the UAS because there is current ly

no precedence for establishing the aircraft worthiness of a UAS nor any certifi cation will be

issued for a UAS for exemption pur p oses.

VERDANT ALPHA submits the equivalent level of safety is maintained because:

 All aforementioned UAS request ed by this exemption have been previousl y granted flight exemptions.

 All aircraft operated in accordance with this exemption shall 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 must be as large as practicable

 Prior to each flight, the PIC shall conduct a pre

- flight inspection and determine the UAS is in a condition for safe flight. The pre

- flight inspection must 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 is prohibited from operating until the necessary maintenance has been performed and the UAS is found to be in a condi tion for safe flight.

 All UAS operated shall comply with all manufacturer safety bulletin s

.

 PIC shall not operate the any of the requested UAS unless the PIC demonstrates the ability to safely operate the UAS in a manner consistent with how the UAS

will be operated under this exemption, including evasive and emergency maneuvers and maintaining appropriate distances from persons, vessels, vehicles and structures. PIC qualification flight hours and currency shall be logged in a manner consistent with 14 CFR § 61.51(b).

B. 

### Section 91.119(c) Minimum Safe Altitudes

Conditional r elief from § 91.119(c) regarding “the aircraft may not be operated closer than 500 feet to any person

, vessel, vehicle, or structure.” is requested. A ll operations shall

adhere to a 400ft AGL and any rest riction s as required to fly in the NAS, but d ata acquisitions such as, but not limited, to civil infrastructure inspections, real estate inspection, construction surveying, environmental monitoring, and agriculture may require operating within 500 f ee t of participating persons, vessels, vehicles, and structures

.7

Any flight ope rations that ex e r cise this relief shall be fil e d as part of a COA and subject to approval. If such COA does not authorize such relief to fly within a 500ft of participating

p e r son, vessels, vehicle, or structur e , then the flight operations cannot exerci se this rel i ef and

must adhere to the 500 feet re stricti ons.

VERDANT ALPHA submits the equivalent level of safety is maintained because :

 All aforementioned UAS requested by this exemption have been previously granted flight exemptions.

 All UAS requested are b elow 55 pounds fully loaded and have minimal impact inertia to cause any significant damage.

 All UAS requested are small < 2200mm wingspan and do not use flammable fue l therefore any malfunction causing an unin tended landing will result in none or

limited property or bodily harm.

 All UAS requested shall follow the operational and safety manuals provid ed per UAS manufacturer.

 All participating person , vessel, vehicle, or structure shall be identified and authority granted by owner or responsible parties to which the aerial capture is

for.

C. Section 91.121 Altimeter Settings

Relief from § 91.121 entitled Altimeter s ettings is required for flight operations because

the UAS systems requested do not use a typical barometric altimeter found in manned aircraft

. T he UAS requested utilizes a GPS receiver to determine altitude instead of a barometric altimeter. In addition to the GPS, all request UAS autopilot s uses a small barome ter for detecting relative altitude changes

.

VERDANT ALPHA submits t he equivalent level of safety is maintained because:

 All aforementioned UAS requested by this exemption have been previously granted flight exemptions.

 All request ed UA S shall operate with in VLOS with a VO.

 UAS shall operate below 400 feet AGL.

 T he altitude information from all UAS shall be provided to the PIC via a radio communications telemetry data link to the GCS.

 Prior to each flight, a zero altitude initiation point and all pre

- flight calibration shall be by performed by the UAS PIC.

D. Section 91.151 (a)(1) Fuel Requirements

Relief fro m § 91.151 (a)(1) entitled Fuel R equirements for F light in VFR conditions, is requested to red uce the time of flight reserves from the first point of landing, assuming normal cruising speed

, to follow manufacturers minimum safe battery levels for both fixed wing and VTOL systems . If none are stated by the UAS manufacturer, VERDANT ALPHA requests the8

fuel requirements to be 25% of manufacturer ’s maximum flight time instead 30 minutes for fixed wing UAS and 25% battery capacity to execute a landing safe for VTOL airframes. F ixed wing UAS systems can glide with minimal power input versus rotor based system found in VTOL, which must always be powered to maintain flight . Therefore, VERDANT ALPHA believes that percent of total flight time for fixed wing and a percentage of battery capa city for VTOL UAS is an appropriate limitations for fuel requirements to maintain a safe flight, in lieu of the lac k of a
manufacturer’s specify minimum fuel requirements

.

VERDANT ALPHA seeks the requested relief because the UAS fixed wing aircraft have a maximum flight time of 40

- 90 min utes depending on configuration with a 1 0min

- 30 flight

reserve respectively . W ithout relief from § 91.151 (a)(1) the maximum flight time for smaller

UAS may be only 20 minutes for small UAS systems and will severely constrain the practicality of any large (300+ acres) aerial data acquisition

.

VERDANT ALPHA seeks the requested relief because the UAS VTOL systems will can safely land on low battery with 25% battery reserves. All UAS VTOL systems applied for in this exemption have a maximum flight time of 25 minutes.

VERDANT ALPHA submits the equivalent level of safety is maintained because:

 All aforementioned UAS requested by this exemption have been previously granted flight exemptions.

 All requested UAS for exemption do not carry passengers and are small ( < 55lbs )

, electrically driven flight platform designed exclusively for aerial data capture s

.

 All requested UAS for exemption ensures safety under low battery conditions by using a combination of audible warning, GCS telemetry, PIC command override during autonomous flight, and autonomous RTL and autonomous land on low

battery conditions

.

 PIC is 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

.

 PIC shall adhere to manufacturers minimum safe fuel limits if specified.

E. Sections 91.405(a), 91.407(a)(1), 91.409(a)(1) & (a)(2), a nd 91.417(a) & (b)
Aircraft Airworthiness

.

Sections 91.405(a), 91.407(a)(1), 91.409 (a)(1) and (a)(2), and 91.417(a) and (b) only apply to aircra ft with an airworthiness certificate

. VERDANT ALPHA requests relief from these

s ections because the requested UAS do not requir e an airworthiness certificate based on current FAA exemptions for UAS operators.

VERDANT ALPHA submits the equivalent level of safety is maintained because:

 Shall p erform maintenance, alterations, and preventive maintenance on the UAS according to the operational manuals of each UAS system.

 Shall d ocument and maintain all maintenance records for the UAS.9  Shall p erform and maintain all flight certification requirements based on the operational manuals

.

 Shall follow the UAS manufacturer’s maintenance, overhaul, replacement, inspection, and life limit requirements for the aircraft and aircraft components.

 All UAS operated shall comply with all manufacturer safety bulletin

.

 Any UAS that has undergone maintenance or alterations that affect the UAS operation or flight characteristics, e.g. replacement of a flight critical component,

shall undergo a functional test flight prior to conducti ng further operations.

IV. The R easons W hy G ranting VERDANT ALPHA R equest W ould Be In the P ublic
I nterest and H ow It W ould B enefit the P ublic as a W hole

.

Granting the present Petition will further the public interest by allowing VERDANT
ALPHA to safely, efficiently, and economically perform aerial acquisitions within the NAS

. Additionally, use of the requested UAS will decrease congestio n of the NAS, reduce pollution, and provide signif

icant benefits to the economy
VERDANT ALPHA operation of the UAS will have no privacy issues.

A. D ecreased congestion of the NAS

A n exemption allowing the use of a UAS for aerial surveying will reduce the amoun t of
manned aircraft in the NAS. The UAS does not require the supervision of an ATC because of the operational altitude and area, nor does the UAS require an airport for takeoff or landing; this allows the ATC to supervise manned aircraft in the NAS without increasing flight operations, equipment, and/or attention. In the event an area requires A TC control, VERDANT ALPHA shall assume responsibility and shall follow all necessary procedures, such as filing a flight plans and radio communications to the ATC to ensure safe operation.

B. Reduction of pollution

A n exemption allowing the use of a UAS will reduce noise and will not contribute to air pollution due to the electric powered motor.

C. Improve , if not maintain, aerial and terrestrial safety

A n exemption will increase the safety of life and property on the ground because of

reduced damage liability of a UAS requested compared to traditional manned aerial operations.

The UA will also remain clear and give way to all manned aviation operations and activities at

all times.

In addition, a ll operations will be co nducted over private or controlled

- access property
with permission from the prop erty owner/controller or authorized representative. Permission from property owner/controller or aut horized representative will be obtained for each flight to be

conducted ther efore operations

.10

D. Increase in agricultural yield, reduce consumption of natural resources, and support local economies , reduce cost to civil infrastructure inspection, reduce NAS congestion for land survey, reduce costs for environmental monitoring, etc.

A n exemption allowing the use of the UAS to perform aerial acquisitions will allow the aforementioned benefits. UAS operations will also reduce the risk and costs associated due to the lower liability from UAS systems versus traditional manned systems used for aerial acquisitions

.
