P4 Pre-Flight checklist

[mdh2861]

All, I am developing a little pre-flight checklist that I can go over. I will probably also develop a "post flight" checklist as well. This may seem like a lot of steps, but most of them take only a few seconds to perform. I feel like a lot of "oops" moments can be avoided with simple preparation. I would love to see additions/modifications to my list below.


1. Visual inspection of P4, body, motors, gimbal

2. Battery in place with full charge

3. Propellers in place, secured and properly installed

4. Trakimo, or other GPS device on & enabled

5. Visual inspection of brackets/guards holding accessories

6. Transmitter battery 2 “bars” or above

7. Transmitter extenders (windsurfers or other) in place

8. Flight area scanned (google maps?) for highest altitude terrain/objects

9. Tablet freshly booted with no apps open

10. Tablet pending updates are disabled (automatic updates are disabled)

11.Mobile hotspot enabled and tablet connected for google maps access

12.Current wind speed and forecast < 15 MPH

13.Aircrat power on

14.Transmitter power on

15.Tablet connected

16.DJI Go (or other) app started

17.Review of aircraft status for errors

18. Review of compass status

19.GPS Satellite signal good

20.Drone not in “sport” mode

21.RTH Altitude AGL good relative to surrounding area

22.Takeoff area is clear of surrounding power lines, location of power lines are noted

23.Automatic takeoff procedure run

24.Home point set automatically

25.Aircraft is ascended to safe flight altitude

26.Final system check in DJI go for any problems/errors

27.Flight

Here's my steps, I use them on both P3 & P4, works great for me.

• Airframe: Prepare & check

• Antennas: correct position
• Props & Locks: attach & check
• RC Battery: Check min 75%
• RC Switches: Correct mode & Gear Down
• iPad: App running, map cached, Airplane mode, Volume Up.
• Airframe: Position for takeoff
• Props: 2nd check
• Power On: Check battery ~100%
• Sensors: Compass 1400 – 1599 (on P4: both in excellent, as low as possible)
• Sensors: IMU +/- 0.1 (on P4: both in excellent, as low as possible)
• Failsafe: Set failsafe height
• Satellite: At least 7 sats & safe to fly box
• Flight Mode: Correct mode selected
• Start Motors: CSC command
• Home Point: Blue dot Location correct on map
• Initial Check: motor sound check
• Climb: climb to 2m, recheck sensors
• Control Tests: Test all controls
• GPS & ATTI Test: Test both modes function correctly
• Landing Gear: Raise Gear and fly!
