March 19th. This Addendum allows for the inclusion of Vertical Take-Off and Landing (VTOL) UA's as 

follows: 

• DJl Phantom 2 Vision+ 

• DJI Phantom 3 

• DJIInspire 1 

Operating procedures are different for VTOL/Multi-Rotor aircraft and therefore we include additional 

procedures in this addendum. 

THE UNMANNED AIRCRAFT (UA}: 

• OJI Models: Phantom 2 Vision+, Phantom 3. and Inspire 1 a lightweight (6.Slb. gross weight and 

under). battery operated Multi-Rotor VTOL aircraft 

• 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 attached to the UA via a three axis gimbal. capable of capturing full color. 

high definition imagery 

• 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 THE SYSTEM: 

• A Pilot in Command (PJC) 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 (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.

APPENDIX A- FLIGHT OPERATIONS/PROCEDURES 

PRE-FLIGHT CHECKLIST 

Prior to operation preflight checklists provided by the manufacturer of the UA's will be followed. 

1. Remote Controller. Smart Battery, Range Extender and Smartphone are fully charged. 

2. Propellers are mounted correctly. 

3. Damping absorbers are in good condition. not broken or worn. 

4.Camera lens cap has been removed. 

s. Micro-50 card has been inserted if necessary. 

6.Gimbal is functioning as normal. 

7. Motors can start and are functioning as normal. 

8.DJI App successfully connects to the UA and camera via Wi-Fi signal. 

TAKE OFF /LANDING PROCEDURES 

Manufacturer recommended Takeoff and Landing procedures will be followed. 

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 

s. Connect the mobile device to the UA. run the OJ I App to enter the camera preview page. 

6.Wait until the LED flight indicator starts to slowly blink green/yellow. This means the aircraft is 

initializing and entering the "Ready to Fly"tReady to Fly (non-GPS)." state. Then proceed to execute the 

esc 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. 

DJI 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; return it to home and land safely. 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.
