Trigger Method
The user actively triggers RTH
During ight, you can trigger RTH by pressing and holding the RTH button on the remote
controller, or tapping from the left side of the camera view and then pressing and
holding the RTH icon.
Aircraft low battery
During ight, if the battery level is low and only sucient to y to the Home Point, a
warning prompt will appear in DJI Fly. If you tap to conrm RTH or do not take action
before the countdown ends, the aircraft will automatically initiate low battery RTH.
If you cancel the low battery RTH prompt and continue ying the aircraft, the aircraft
will land automatically when the current battery level can only support the aircraft long
enough to descend from its current altitude.
Auto landing cannot be cancelled but you can still y the aircraft horizontally by moving
the pitch stick and roll stick, and change the descent speed of the aircraft by moving the
throttle stick. Fly the aircraft to a suitable place for landing as soon as possible.
• When the Intelligent Flight Battery level is too low and there is not enough
power to return home, land the aircraft as soon as possible. Otherwise, the
aircraft will crash after the battery power is completely depleted.
• DO NOT keep pushing the throttle stick upward during auto landing. Otherwise,
the aircraft will crash after the battery power is completely depleted.
Loss of remote controller signal
When the remote controller signal is lost, the aircraft will automatically initiate Failsafe
RTH if the Signal Lost Action is set to RTH.
When the lighting and environment conditions are suitable for the vision system, DJI Fly
will display the RTH path that was generated by the aircraft before the signal was lost. The
aircraft will start RTH using Advanced RTH according to the RTH settings. The aircraft will
remain in RTH even if the remote controller signal is restored. DJI Fly will update the RTH
path accordingly.
When the lighting and environment conditions are unsuitable for the vision system, the
aircraft will brake and hover, then enter Original Route RTH.
• If the RTH distance (the horizontal distance between the aircraft and the Home Point)
is farther than 50 m, the aircraft adjusts its orientation and ies backward for 50 m on
its original ight route before entering Preset RTH.
