Smart RTH
If the GPS signal is suciently strong, Smart RTH can be used to bring the aircraft back to the Home
Point. Smart RTH is initiated either by tapping in the DJI GO 4 or by pressing and holding the RTH
button on the remote controller.
Exit Smart RTH by tapping in the DJI GO 4 or by pressing the RTH button on the remote controller.
Low Battery RTH
Low Battery RTH is triggered when the Intelligent Flight Battery is depleted to the point that the safe
return of the aircraft may be aected. Return home or land the aircraft immediately when prompted. DJI
GO 4 displays a warning when the battery level is low. The aircraft will automatically return to the Home
Point if no action is taken after a ten-second countdown. The user can cancel RTH by pressing the RTH
button or Flight Pause button on the remote controller.
If RTH is cancelled following a low battery level warning, the Intelligent Flight Battery may not have
enough charge for the aircraft to land safely, which may lead to the aircraft crashing or being lost. The
thresholds for the battery level warnings are automatically determined based on the aircraft’s current
altitude and distance from the Home Point.
The aircraft will land automatically if the current battery level can only support the aircraft long enough
to descend from its current altitude. The user cannot cancel the auto landing but can use the remote
controller to alter the aircraft’s orientation during the landing process.
Return to Home
The Return to Home (RTH) function brings the aircraft back to the last recorded Home Point. There are
three types of RTH: Smart RTH, Low Battery RTH, and Failsafe RTH. This section describes these three
scenarios in detail.
