Smart RTH
Use the RTH button on the remote controller when GNSS is available to initiate Smart RTH. The aircraft will
then automatically return to the last recorded Home Point. Use the remote controller to control the aircraft’s
speed or altitude to avoid a collision during the Smart RTH process. As the aircraft returns, it will use the
primary camera to identify obstacles as far as 300m in front, allowing it to plan a safe route home. Press and
hold the Smart RTH button once to start the process, and press the Smart RTH button again to terminate
the procedure and regain full control of the aircraft.
Low Battery RTH
The low battery level failsafe is triggered when the DJI Intelligent Flight Battery is depleted to a point that
may aect the safe return of the aircraft. The user can cancel the RTH procedure by pressing the RTH
button on the remote controller. The thresholds for these warnings are automatically determined based on
the aircraft’s current altitude and distance from the Home Point. The Low Battery RTH will only be triggered
once during the same ight.
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.
The Battery Level Indicator is displayed in the DJI GS RTK app, and is described below:
