Propulsion System Failure
Propulsion System Failure
Loss of Propulsion - Single Motor Out
WARNING: Propulsion Failure During Flight May Result in loss of lift and degraded flight performance, resulting in Hull loss to unmanned aircraft, or significant damage to persons, properties or critical infrastructure (MAJOR)
INDICATIONS
Warning messages about propulsion failure on GCS
- Critical: ESC failure
- Critical: Motor Failure
- Critical: Motor(s) Not Responding
- Warning: Attitude Control Lost
- Critical: Flight Control Failure
- Critical: Vibration Levels High
- Emergency: System Failure - Landing
Visual lack of propeller rotation
Erratic flight behavior.
NOTE: The redundancy of the coaxial motor configuration enables the aircraft to remain in stable flight in the event of a single motor failure.
NOTE: In the event of a dual motor failure, the aircraft can still remain airborne provided the two failed motors are on opposite arms from one another.
FAILSAFE BEHAVIOR
There is no Failsafe for this emergency.
PROCEDURE
AMC Warning Message “Motor # Timed Out” VERIFY
EMERGENCY LOSS OF PROPULSION ANNOUNCE
WARNING: Motor failure may result in degraded, intermittent, or complete loss of propulsion of impacted motor. Degraded control of yaw and altitude is expected. These conditions may result in significant damage to aircraft, persons, or property.
Uncrew: Return to Home Button SELECT
ArUco Tag REMOVE
Once in Landing Phase, Uncrew: Land in Place Button SELECT
CAUTION: The Uncrew Land in Place command should be used prior to the precision landing mode engaging and when directly over the landing location. If the precision landing mode is engaged and locks with a single motor out, a rapid landing will occur resulting in damage to landing gear.
