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

Aviation Regulations

Dear Sir or Madam:

On Behalf of Professional Engineering Consultants

, Inc.

, and Pursuant to Section 333 of the FAA

Modernization and Reform Act of 2012 and 14 C.F.R. Part 11, I Nick Moore, Project Manager am seeking

an exemption from Part 21 Subpart H ; and Sections 91.203 (a) (1)

, 45.23 (b) , 91.7 (a), 91.9, 61.113,

61.133, 9 1.109, 91.119, 91.1 21, 91.151, and (91.401

- 91.417 ) Subpart E, of Title 14, Code of Federal

Regulations (14 CFR). This proposed exemption would allow for the operation of our unmanned aircraft

(UA) the DJI Phantom 3, and the 3D Robotics (3DR) Solo

THE UNMANNED AIRCRAFT (UA):

 The UA’s are lightweight (under 55l b. gross weight), battery operated multi Rotor copter s that

take off and land vertically and have the ability to hover in one location during flight.

THE UA INCLUDES:

 An on

- board flight computer with GPS navigation and location ability that receives signals for

flight controls from a ground

- based transmitter/controller;

 An on

- board camera capable of capturing imagery in the form of full color, high definition still

photos and video

 An on

- board telemetry system that delivers flight data from the on

- board flight computer to the

on

- board radio transmitter including altitude AGL, horizontal and vertical speed, compass

direction of flight and direction back to its launch site

 On

- board radio tra nsmitter that transmits live video from the on

- board camera plus all the flight

data from the telemetry system described above

THE GROUND STATION PART OF THE SYSTEM:

 A Pilot in Command (PIC) I n operati onal control of a mission from beginning to end, and w ho

controls the UA while in the air

 A radio transmitter/controller operated by the PIC to control the UA while in flight

 Ground Station (computer, tablet for smart phone based app) which receives and displays video

and system telemetry real time from the UA

 A Visual Observer (VO), a person who provides a second pair of eyes to visually track the UA

while in flight.Professional Engineering Consultants, Inc.

PILOT IN COMMAND (PIC) AND VISUAL OBSERVER:

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 per form maintenance on the system and will complete a

course of maintenance instruction as part of their initial training.

I submit that the combination of the UA’s light weight, flight performance and abil ity, fully qualified

flight crew and strict operation under the guidelines established in 8900.227, and under all of the

Restrictions listed above, the FAA can have full confidence that the operation wil l have an equivalent or

greater level of safety than manned aircraft performing the same mission.

INTENDED USE :

The requested exemption would allow us to use UA’s for aerial image acquisition to support various

mapping and surveying applications as well as video documentation of civil project sites. Typical

applications would include, but are not limited to:

 Aerial Photography

 Real Estate Photography

 Construction Site Monitoring

 Videography

 Aerial Mapping

 Aerial Surveys

 Volumetric Surveys

 Bridge Inspection s

PUBLIC INTEREST:

The ability to capture aerial imagery using UA’s from a low altitude including oblique photos and video

from several angles is far more effective than ground

- based imagery for displaying the characte ristics of

buildings, sites and/or properties where consistent monitoring is needed. I n addition using UA’s allow us

the ability to provide these services at a m uch lower cost than chartering fixed wing aircraft or

helicopters which we currently do. The reduced cost and higher quality data from the UA is beneficial to

the public in many app lications including: real estate photography, accident or crime scene

investigation, search and rescue, terrain mapping to delineate flood prone areas, bridge inspections and

the preservation of historic buildings or archeological sites where access is lim ited due to the sensitive

nature of the site

PUBLIC SAFETY :

UA’s, are powered by batteries, they are smaller, lighter and more maneuverable than larger aircraft

running on combustible fuel; they operate at lower altitudes (under 400’) with no people on b oard

thereby reducing current risk levels and enhancing public safety. With a small payload and maximum

flight time of approximately 2 2 minutes , UA’s offer little or no risk to national security.

In addition both the DJI and 3DR models ha ve their own buil t in flight restrictions in special areas such as

airports, which limit flight in these areas. More information can be found in the UA’s User Manual or on

DJI’s website at https://www.dji.com/fly

SUMMARY GRANT REQUEST :

This request follows many others using similar systems and process tha t have been granted previously. I

am requesting the FAA issue a summary grant of exemption, as this request would not set a precedent

.

 The reasons stated by the FAA for granting Exemption N os. 11624, 12026, 12366 and 12369 also

apply to this request

 A grant of exemption would be in the public interest.

 Any delay in approving this exemption request will have a negative financial impact on our

current aerial mapping operations.

a pp l y t o the op e r a t i on s of the DJI Phantom 3, and the 3D Robotics (3DR) Solo

14 C.F.R. Part 21, Subpart H: Airwo rthiness Certificates 14 C.F.R. 91.203 (a) (1)

Subpart H, entitled Airworthiness Certificates, establishes the procedura l requirements for the issuance

of airworthiness certific ates as required by FAR 91.203( a) (1).

Given the size and limited operating area associated with the UA to be utilized by the Petitioner, an

exemption from Part 21 Subpart H meets the requirements of an equivalent level of safety under Part

11 and Section 333 of the FMRA. The Federal Aviation Act (49 U.S.C.44701 (f)) and Section 333 of the

FMRA both authorize the FAA to exempt aircraft from the requirement for an airworthiness certificate,

upon consideration of the size, weight, speed, operational capability, and proximity to airports and

populated areas of the particular UA. In a ll cases, an analysis of these criteria demonstrates that the UA

operated without an airworthiness certificate, in the restricted environment and under the conditions

proposed will be at least as safe, or safer, than a conventional aircraft (fixed wing or rotorcraft)

operating with an airworthiness certificate without the restrictions and conditions proposed. The UA to

be operated hereunder is less than 55 lbs. fully loaded, is by definition unmanned and carries neither a

pilot nor passenger, carries no exp losive materials or flammable liquid fuels, and operates exclusively

within a limited flight area. Unlike other civil aircraft, operations under this exemption will be tightly

controlled and monitored by the Operator and will also remain within the require ments of, and in

compliance with, local public safety requirements. These safety enhancements, which already apply to

civil aircraft provide a greater degree of safety to the public and property owners than conventional

operations conducted with airworthin ess certificates issued under 14 C.F.R. Part 21, Subpart H. Lastly,

application of these same criteria demonstrates that there is no credible threat to national security

posed by the UA due to its size, speed of operation, location of operation, lack of ex plosive materials or

flammable liquid fuels, and inability to carry a substantial external load.

14 C.F.R. 45.23 (b). Marking of the Aircraft

The regulation requires; When marks include on ly the Roman capital letter "N" and the registration

number is displayed on limited, res tricted or light

- sport category aircraft or experimental or

provisionally certificated a ircraft, the operator must also display on that aircraft near each entrance to

the cabin, cockpit, or pilot stat ion, in letters not less than 2 inches nor more than 6 in ches high, the

words "limited," "restricted," "light

- sport," "experimental," o r "provisional," as applicable.

Even though the UA will have no airworthiness certificate, an exemption may be needed as the UA will

have no entrance to the cabin, cockpit or pilot station on which the word "Experimental" can be placed.

Given the size of the UA, two

- inch lettering will be impossible. The word "Experimental" will be placed

on the fuselage in compliance with 45.29 (f). The equivalent leve l of safety will be provided by havingProfessional Engineering Consultants, Inc.

the UA marked on its fuselage as required by 45.29 (f) where the pilot, observer and others working

with the UA will see the identification of the UA as "Experimental."

The FAA has issued the following e xemptions to this regulation to Exemptions Nos. 10700, 8738, 10167

and 10167 A.

14 C.F.R. 91.7(a): Civil aircraft airworthiness.

The regulation requires that no person may operate a civil aircraft unless it is in airworthy condition.

As there will be no airworthiness certificate issued for the aircraft, should this exemption be granted, no

FAA regulatory standard will exist for determining airworthiness. Given the size of the aircraft and the

requirements contained herein for the use of safety check lists prior to each flight, an equivalent level of

safety will be provided.

Manufacturer recommended Takeoff and Landi ng procedures will be followed.

Place the UA on ground with the battery level indicator facing you.

1. Po wer on the remote controller.

2. Power on the range extender.

3. Power on or connect sensor.

4. Power on the aircraft by turning on the battery

5. Connect the mobile device (Ground Station) to the UA

.

6. Wait until the LED flight indicator lights indicate good GPS connectivity and Ready to Fly

.

7. Push the throttle stick up slowly to lift the aircraft off the ground.

8. When landing, hovering over a level surface, p ull down on the throttle stick gently to

descend and land.

9. After landing the aircraft on the ground, keep the throttle stick down while the motors

come to a complete stop.

FAILSAFE FUNCTION

The UA will enter Failsafe mode when the connection from the remote controller is lost. The flight

control system will auto matically control the aircraft to return to home and land to reduce injuries or

damage. The following situations would make the aircraft fail to receive a signal from the remote

controller and enter Failsafe mode:

1. The remote controller is powered off.

2. The aircraft has flown out of the effective communication range of the remote controller.

3. There is an obstacle obstructing the signal between t he remote controller and the aircraft,

essentially reducing the distance the signal can travel.

4. There is interferen ce causing a signal problem with the remote controller.Professional Engineering Consultants, Inc.
