Loss of GPS
Do the following:
1.
If the GPS signal degrades until it is not working properly, or fails completely, you can still fly the aircraft
in Altitude Hold or Stabilize flight modes. The difference between these two modes is that in Altitude
Hold mode the aircraft altitude is automatically held using on board sensors Roll, Pitch, and Yaw are all
under manual control. It is recommended that new pilots intentionally switch into these modes in a safe
environment in order to gain practice and be prepared in case of an emergency.
2.
Bring the aircraft back to the landing area if you are able and land immediately.
3.
If you cannot return to your landing area, then land immediately in the area of GPS loss if the area is suit-
able and safe for landing.
Loss of Command and Control Link
Do the following:
1.
If you lose your data link/command and control functionality of the aircraft, then after 3 seconds the air-
craft will switch to fail-safe RTL. This will bring the aircraft back to the takeoff location and automatically
land.
2.
Ensure the landing area is clear and continue to monitor the aircraft and the surroundings for any danger-
ous situations that may arise.
Loss of Telemetry Data Link
Do the following:
1.
If you lose your video and telemetry data link, yet still have control of the aircraft through the GCU, it is
possible to continue to fly the aircraft.
2.
In some cases a loss of this link will cause the QGroundControl application to lock up. If this happens it is
possible to close the application and reopen it to reestablish the link. However, exercise caution when
doing so and ensure that the pilot remains in full control of the aircraft at all times.
3.
If the telemetry link cannot be reestablished immediately return the aircraft to a safe location and land it.
Without a telemetry link an operator is not able to monitor power status or receive critical in-flight warn-
ings being issued by the aircraft.
Loss of Video Link
Do the following:
1.
With a loss of video link you will still have command and control of the aircraft.
2.
You may have flown too far away or have run into signal interference.
3.
Try flying back toward your location to pick up signal again.
