Smart RTH
Use the RTH button on the remote controller when GPS is available to enable Smart RTH. During
the Smart RTH procedure, the aircraft returns to the last recorded Home Point but you may
control the aircraft's orientation to avoid collisions. Press the Smart RTH button once to start the
process. Press the Smart RTH button again to exit Smart RTH and regain the control.
If using the DJI Lightbridge 2, no additional settings are required for the RTH button.
If using another type of remote controller, you must congure the RTH button in DJI
Assistant 2.
Low Battery RTH with LiPo battery
The low voltage failsafe is triggered when the DJI LiPo Battery is depleted to a point that
may aect the safe return of the aircraft. Users are advised to return home or land the aircraft
immediately when these warnings are shown. Aircraft will automatically return to the Home Point
if no action is taken after 10 seconds countdown. Cancel the RTH procedure by pressing once
on the RTH button. The thresholds for these warnings are automatically determined based on the
current aircraft altitude and its distance from the Home Point.
Aircraft will land automatically only if the current voltage can support the aircraft in landing on
the ground from the current altitude. Use the remote controller to control the aircraft’s orientation
during the landing process.
When the critical battery level warning activates and the aircraft is descending to land
automatically, you may push the throttle upward to hover the aircraft and navigate it to a
more appropriate location for landing.
Attitude Control When One Motor Output Fails
For multirotor aircraft, the A3/A3 Pro ight control system can control the aircraft’s attitude when
one motor fails:
1. During ight, the aircraft with A3/A3 Pro ight control system is attitude controllable when one
motor output fails
2. The motor will not start before take-o. (DJI Intelligent ESCs are required for communication.)
Select Course Lock or Home Lock mode to y the aircraft to a safe area to land when the aircraft
is far away, or the attitude can’t be recognized.
Propulsion System Protection
Low voltage and overweight aircraft warnings are provided in the DJI GO app.
