Pre and Post Flight Checklists- DJI LightBridge 2015+ UA V's 

Phantom 3, Phantom 4, Inspire, and MlOO 

Terminology/Nomenclature: 

'Aircraft' is used to refer to the DJI Phantom 3 Professional and is considered interchangeable with UAV, Drone, Quadcopter. 

'iPad' is used to refer to the iOS or Android SmartPhone or Tablet used to run the Dn GO App software. Note: This document is written specifically 

for use with an Apple iOS device and does NOT take into account any functional differences for Operators using an Android device to run the Dn 

GOApp. 

'RC Unit' is used to refer to the DJI Radio Control unit. 

Operational Area Checklist 

l. Verify no sources of potential interference such as large metal surfaces, ferromagnetic materials on person or near UA V or metal 

underground structures (rebar, pipes or conduit, etc) in or around the immediate calibration area. 

2. 

l. Confirm and record distances (use Laser Range Finder if possible). 

I. Take-off/Landing distance to POI. 

2. Perimeter (comer to comer lengths). 

3. Centre of POI to Max Radius for Orbit Mode. 

4. Max heights of all vertical structures (buildings, hydro wires, trees, ... hydro poles & light posts are typically 20- 25 

meters). 

5. Confirm a clear "As the crow flies" direct path from POI to Launch/Land position. 

6. Make note of minimum altitude for RTH (Return to Home) flight path based on potential obstructions (posts, trees, 

structures). Typically at least 50 meters. 

7. Confirm maximum height of structure to be Orbited or flown over (Minimum Collision Height). 

Aircraft and Controller Preflight Checklist 

l. Firmware Make sure Aircraft, RC Unit, Smart Batteries and iOS device control software and firmware has been updated prior to arriving 

on-site. This typically requires a WiFi connection which might not be available on-site. 

2. Props- Secure by hand or with DJI wrench (Gray cap props on gray posts and clock-wise to tighten, Black cap props on black 

posts and counter clock-wise to tighten). 

3. Battery (Aircraft)- Fully charged and installed correctly (fully seated and locked in-place flush with hull). 

I. Red LED lit solid and not flashing. 

2. Four (4) Green LEDs lit and not flashing. 

4. Battery (RC Controller) Fully charged. 

l. First LED lit solid Red and not flashing when powered on. 

2. Next four ( 4) LEDs lit white and not flashing when powered on. 

5. Battery (iPad)- Fully charged to 97-100%. 

6. Lens cover, gimbal lock and Aircraft gimbal clamp removed and stored.

10. Apple MFI Certified Lightening cable plugged into iPad with USB connector plugged into RC Unit. 

11. If using Sun Shroud ensure cable is properly routed through access hole and plugged in without sharp bends or binding. 
J 2. Antennas- Up and vertical. 

13. Flight Mode Toggle Switch in 'P Mode' which is Positioning Mode. This means the Flight Control and Piloting is assisted by the aircraft 

utilizing all or a combination of GPS positioning, Vision positioning and Barometer positioning. It means you are piloting but the Dll GO 

App knows where you and the aircraft are in 3D airspace. · 

iOS Device Preflight Checklist

2. Screen Brightness- Set to bright and Auto-Brightness Disabled in Settings. 

3. DJI GO App- Ensure you are using the latest Stable Build. 

4. DJI GO settings- Pre-selected prior to mounting on RC Unit if possible (convenience). 

5. Mode- To get to 'Orbit' or additional 'Assisted Intelligent Flying Modes' you need to toggle from 'P' to 'F' on the RC Unit. In this case 

and for the scope of this Check List document you are flying Manually in 'P Mode' which means you are in complete control. 

6. Aircraft status bar- Displays Connected/Ready when all units powered up. 

7. Control settings Confirm all settings baSed on Mission and Flight Requirements. Specific Settings and Configurations are covered in a 

separate SFOCS (Specific Flight Operations Cheat Sheet) document. 

Pre-Launch Setup 

1. Micro SD card inserted into Aircraft camera slot. 

2. Check battery status shows fully charged for all devices. 

3. Check propellers are locked and on proper axis (black to black and gray to gray). 

4. Ensure iPad is securely mounted and clamped and cabled to RC Unit. 

5. Confirm RC Unit antennas are properly positioned (upright). 

6. Confirm RC Unit flight mode to "P" position. 

7. Confirm Aircraft is positioned on level surface (appropriate HOME position). 

8. Ensure Aircraft nose is pointing away from operator (Direction of Flight) 

9. Start Power Up Sequence: 

I. RC Unit- Power ON 

1. Press Power button once, twice, third time and hold 2-3 seconds and release. All LEDs will light up and unit will beep. 

2. iPad- Power ON. 

3. Aircraft- Power On 

I. Press battery button once, twice, third time and hold 2-3 seconds and release. 

NOTE: For safety when powering on the Aircraft ensure your hands and forearms are below the propellers when 

pressing the battery button to power on the Aircraft. Use your second hand, also kept below propeller level to hold the 

Landing Gear to keep the Aircraft stationary during the Power Up sequence. 

2. Aircraft should emit a series of Beeps. 

3. The camera and gimbal will complete a few full rotations and stop 'in-position' and forward facing when ready.

lnflight Checklist 

I. Aircraft - Confirm mode perfomiance. 

2. Battery/Telemetry- Monitor performance. 

3. Land Land manually or hit the Return to Home and Auto-Land options to land the aircraft. 

4. NOTE: When landing the aircraft fly as close to the original Take-off/Landing location as possible, hover and then using the left stick 

slowly descend until the aircraft is on the ground. Release the sticks and the aircraft will remain on the ground. To Power Down there are 

two (2) options. 

1. Repeat the CSC operation you used to initially start-up the aircraft (both sticks simultaneously down and centered). 

1. I do not recommend this option as there is typically a sudden surge as the props Spin-Up before powering down 

the aircraft and this .invariably 'jumps' the aircraft and flips it onto its side which may cause propeller, camera or 

gimbal damage. 

2. Use the Left Stick and pull straight back and hold for 2-3 seconds. This will power down the aircraft without the surge 

and is the safest way to end your flight. ·

directly. To do this connect the USB end ofthe cable to your computer and the Micro-USB end of the cable to the Data Port at 

the front ofthe aircraft and then launching the DJI GO App. 

Warning: Always check your equipment for visible damage and cleanliness and regularly maintain your aircraft and RC Unit in order to 

ensure maximum safety and trouble free operation. Read the Owner and Operations Manual completely before your first flight and always 

refer back to the manuals for Safe Operating and Maintenance Procedures. Ensure to follow the Scheduled Maintenance and Storage 

procedures for the DJI Intelligent batteries. 

Fly Safe. Fly Responsibly; Fly Often.
