RTH Procedure
Smart RTH, Low Battery RTH, and Failsafe RTH follow this procedure:
1. The aircraft adjusts its orientation.
2. a. If the aircraft is further than 20 m from the Home Point it ascends to the pre-set RTH attitude and
then ies to the Home Point.
b. If the aircraft is between 5 m and 20 m from the Home Point:
i. If the RTH at Current Altitude option is enabled (the default setting in DJI GO 4) the aircraft ies
to the Home Point at the current altitude, unless the current altitude is less than 2.5 m, in which
case the aircraft ascends to 2.5 m and then ies to the Home Point.
ii. If the RTH at Current Altitude option is disabled, the aircraft lands immediately.
c. If the aircraft is less than 5 m from the Home Point it lands immediately.
5. The aircraft lands and stops its motors once it reaches the Home Point.
Obstacle Avoidance During RTH
The Mavic Air senses and actively attempts to avoid obstacles during RTH, provided that lighting
conditions are sufficient for the Forward and Backward Vision Systems to operate. The obstacle
avoidance procedure is as follows:
1. The aircraft decelerates when an obstacle is sensed.
2. The aircraft stops and hovers then starts ying backward and ascends vertically until no obstacle is
sensed.
3. The RTH procedure resumes. The aircraft ies to the Home Point at the new altitude.
The aircraft will not be able to return to the Home Point if the GPS signal is weak or if GPS is
unavailable.
In Smart RTH and Low Battery RTH, during the aircraft’s ascent to its RTH altitude, the ascent
is automatic until an altitude of 65 ft (20 m) is reached. Once the altitude is 65 ft (20 m) or
higher, moving the throttle stick commands the aircraft to stop ascending and to y to the
Home Point at its current altitude.
The aircraft will not be able to avoid obstacles during Failsafe RTH if the Forward and
Backward Vision Systems are unavailable. It is important to set a suitable RTH Altitude before
each ight. Launch the DJI GO 4 app, tap and then set the RTH Altitude.
The aircraft cannot avoid obstacles above or beside the aircraft.
During the RTH procedure the aircraft’s speed and altitude can be controlled using the remote
controller or the DJI GO 4 app, but its orientation and direction of ight are controlled by the
ight controller.
