DJI Mini 2 User Manual
aircraft to land safely, which may lead to the aircraft crashing or being lost.
The aircraft will land automatically if the current battery level can only support the aircraft long enough
to descend from its current altitude. Auto landing cannot be canceled but the remote controller can be
used to alter the direction of the aircraft during the landing process.
Failsafe RTH
If the Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH
automatically activates after the remote controller signal is lost for more than 11 seconds.
When the rmware is updated to v1.1.0.0 and above, the aircraft will y backwards for 50 m on its
original ight route and ascend to the preset RTH altitude to enter Straight Line RTH. The aircraft enters
Straight Line RTH if the remote controller signal is restored during Failsafe RTH. When the aircraft ies
backwards along the original ight path and the distance from the Home Point is less than 20 m, the
aircraft stops ying backward on the original ight route and enters Straight Line RTH at the current
altitude.
In DJI Fly, users can change the settings of how the aircraft responds when the remote controller signal
is lost. The aircraft will not execute Failsafe RTH if land or hover has been selected in the settings.
Other RTH Scenarios
There will be a prompt to initiate RTH if the video link signal is lost during flight while the remote
controller is still able to control the movements of the aircraft. RTH can be cancelled.
RTH Procedure (Straight Line)
1. The Home Point is recorded.
2. RTH is triggered.
3. If the aircraft is less than 20 m from the Home Point when RTH begins, it will hover in place and not
return to home (rmware version v1.1.0.0 is required. Otherwise, the aircraft will land immediately).
If the aircraft is further than 20 m from the Home Point when RTH begins, it will return home at a
horizontal speed of 10.5 m/s.
4. After reaching the Home Point, the aircraft lands and the motors stop.
The aircraft cannot return to the Home Point if the GPS signal is weak or unavailable. If the GPS signal
becomes weak or unavailable after RTH is triggered, the aircraft will hover in place for a while before
landing.
It is important to set a suitable RTH altitude before each ight. Launch DJI Fly and set the RTH
altitude. In Smart RTH and Low Battery RTH, if the current altitude of the aircraft is less than the RTH
altitude, it automatically ascends to the RTH altitude rst. If the altitude of the aircraft reaches or is
higher than the RTH altitude, it will y to the Home Point at its current altitude.
If the aircraft is at an altitude of 65 ft (20 m) or higher and has not yet reached the RTH altitude, the
throttle stick can be moved to stop the aircraft from ascending and the aircraft will y to the Home
Point at its current altitude (only available with rmware v1.0.0.0. This function is not available when
the rmware is updated to v1.1.0.0 or later).
