Temporary Loss of Aircraft Control in Auto Mode

Temporary Loss of Aircraft Control while Flying in Auto Mode is defined as an aircraft that is momentarily behaving unexpectedly, dangerously, or abnormally while in an automated flight mode (mission, RTL, or Land). Different from turbulence, loss of control typically results in a large, noticeable correction maneuver/attempt by the aircraft that saturates the aircraft's control authority. It is most likely the result of abnormal external influence on the aircraft or an issue with the aircraft itself.

If experiencing temporary loss of aircraft control, the Pilot in Command should switch to manual Position Hold or Loiter flight mode upon observation of such an event, to regain control. This is recommended because attempting automated flight maneuvers can reduce the aircraft’s ability to correct for large anomalies.

The aircraft will automatically pause a mission if it detects loss of control.

Upon regaining aircraft control the Pilot in Command should manually return to home and land using docile inputs. Upon landing inspect the UAS for damage or abnormalities which could explain the temporary loss of control.

Example: Chipped or broken propeller blade, incorrectly attached payload.
