Flight Test Checklist

Flight Test|

1. Make sure that there are no potential safety hazards or people within 5 m of the aircraft.

2. Make sure that the satellite count is more than 10 and there is sufficient light. Start video recording.

8. Set height limits and distance limits. Then test if the aircraft can obey the limits.

9. In P-mode, enable obstacle sensing. Then test if the aircraft can avoid obstacles in front and upward directions.

10. In P-mode, fly the aircraft more than 20 m away from the Home Point at an altitude less than the preset RTH altitude. Initiate RTH using the RTH button on the remote controller to test if the aircraft can perform ascending, cruising, landing in order and the landing position has an error no more than 1 m from the Home Point.

11. Stop video recording after landing.

12. Once a high-value payload is used, perform the flight test without payload first, make sure that the aircraft is ready for use. And then out the payload to perform the flight test again.
