Re: Addendum to add additional Unmanned Aerial Systems to current Exemption/Rulemaking request

Dear Sir or Madam:

I, Rebecca Morton, President of GeoWing Mapping, Inc., have prepared the following addendum to our 

Current Exemption/Rulemaking request filed on February 27th 2015. 

This Addendum allows for the inclusion of four additional Vertical Take-Off and Landing (VTOL) MultiRotor UA’s as follows:

 DJI Phantom 2 Vision+ 

 DJI Phantom 3

 DJI Inspire 1

 DJI Spreading Wings S900 

 DJI Spreading Wings S1000

 DJI Spreading Wings S1000+

THE UNMANNED AIRCRAFT (UA):

 The DJI Models: Phantom 2 Vision +, Phantom 3, Inspire 1, S900, S1000, and S1000+ are 

lightweight (under 55lb gross weight), battery operated Multi-Rotor VTOL aircraft 

 Each uses an on-board flight computer with GPS navigation and location ability that receives 

signals for flight controls from a ground-based transmitter/controller

 Each have an on-board camera attached to the UA via a three axis gimbal, capable of capturing 

full color, high definition imagery 

 Each has 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

THE GROUND STATION-BASED PART OF THESE SYSTEMS:

 A Pilot in Command (PIC) in operational control of a flight operation from beginning to end and 

who controls the UA while in the air

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

 A Ground Station (Laptop, Tablet or Smart Phone based App) which receives and displays real 

time system telemetry and imagery from the UA

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

while in flight.

This Addendum makes no other changes to the original request including exemptions sought, reasons 

for exemption request, and/or operating parameters. GeoWing Mapping, Inc., will operate these 

additional UA’s under the same conditions and limitations provided in the original 

Exemption/Rulemaking request. 

The name and contact information of the applicant remains the same: 

Sincerely,

Rebecca Morton (Becky)

APPENDIX A – MULTI ROTOR OPERATING PROCEDURES

MULTI ROTOR PRE-FLIGHT CHECKLIST

Once on site the Pilot-In-Command (PIC) and a Visual Observer (VO) will:

 Assess the area for potential hazards

 Determine the take-off and landing (return to home) location 

 Place signage if necessary noting survey in progress

 Brief all personnel present on the upcoming aerial acquisition 

 Instruct those not involved in the aerial acquisition on a safe viewing location

The PIC and VO will then move all equipment necessary to the launch location.

At this time the PIC and/or VO will go through the preflight checklists provided by the manufacturer of 

the UA. Example below.

 Remove the UAS from its case 

 Insert battery 

 Install and/or confirm propellers are tightened

 Connect the Ground Station device to the Flight Controller 

 Turn on the Flight Controller and Ground Station Device 

 Turn the UAS on and run system checks 

 Ensure communications between the UAS, Flight Controller and Ground Station Computer 

are operating properly 

If everything appears to be operating correctly the PIC will then begin the mission.

TAKE OFF/LANDING PROCEDURES 

Manufacturer recommended Takeoff and Landing procedures will be followed. Example below.

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

1. Power on the remote controller.

2. Power on the range extender.

3. Switch the camera to the “WIFI ON” position.

4. Power on the aircraft by turning on the intelligent battery

5. Connect the mobile device or laptop to the UA, run the Ground Station App to enter the 

camera preview page.

6. Wait until the UA is initializing and entering the “Ready to Fly”/“Ready to Fly (non-GPS).” 

state. Then proceed to execute the CSC command to start motors.

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

8. When landing, be sure to be hovering over a level surface. Pull down on the throttle stick 

gently to descend and land.

9. After landing the aircraft on the ground, keep the throttle stick at its lowest position for 

about 3 to 5 seconds which will automatically stop the motors.
APPENDIX A – MULTI ROTOR OPERATING PROCEDURES

DJI MULTI ROTOR FAILSAFE FUNCTION

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

control system will automatically 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 the remote controller and the aircraft, 

essentially reducing the distance the signal can travel.

4. There is interference causing a signal problem with the remote controller.

Upon completion of mission the PIC will log information about the flight while the VO advises those in 

the area that the mission is complete, removes any signage and begins breakdown of the UA
