Failsafe
LOSS OF COMMUNICATION
If the communication link between the aircraft and the GCS is lost, ELIOS 2 will automatically enter the
emergency landing mode. It will slowly descend and land on the ground, wait for 30s, and then shut
down the motors.
The aircraft will leave this mode if the communication link is re-established, after which flight may be
resumed.
BATTERY LEVEL CRITICAL
If the battery reaches a critical level, ELIOS 2 will automatically enter the emergency landing mode,
and the aircraft will slowly descend. The pilot is still able to override this behavior. However, to prevent
any accident, the drone should be landed and turned off within 30sec.
OVERRIDING THIS FAILSAFE FOR TOO LONG MIGHT RESULT IN
PERMANENT DAMAGE TO THE BATTERY AND COULD RESULT IN A CRASH.
