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.
