Failsafe RTH
If the Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH will
be automatically activated if the remote controller signal is lost for more than three seconds. The Return-
to-Home process may be interrupted and the operator may regain control of the aircraft if the remote
controller signal connection is re-established.
Failsafe Illustration
When Critical battery level warning is triggered and the aircraft begins to land automatically,
you may push the throttle upward to make the aircraft hover at its current altitude, giving you an
opportunity to navigate to a more appropriate landing location.
The colored zones and markers on the battery level indicator bar reflect the estimated
remaining flight time. They are automatically adjusted according to the aircraft’s current location
and status.

Aircraft cannot return to the Home Point when GPS signal is weak ( [
] displays grey) or
unavailable.
Aircraft automatically descends and lands if RTH is triggered when the aircraft flies within a 20
meters (65 feet) radius of the Home Point. Aircraft will stop ascending and immediately return to
the Home Point if you move the throttle stick if the aircraft reaches 20 meters (65 feet) altitudes
or beyond during Failsafe.
The aircraft cannot avoid obstruction during the Failsafe RTH, therefore, it is important to set an
suitable Failsafe altitude before each flight. Launch the DJI GO app and enter “Camera” and
select “MODE > Advanced Settings > Failsafe mode” to set the Failsafe altitude.
User cannot control the aircraft while the aircraft is ascending to its failsafe altitude. However,
user can press RTH button once to exit ascending and regain control.
