When the Critical Low Battery level warning is triggered and the aircraft begins to land
automatically, throttle up using the virtual joysticks or control sticks to keep the aircraft at
its current altitude. This gives you an opportunity to navigate to a more appropriate landing
location.
The colored zones and markers on the battery level indicator bar reflect the estimated
remaining flight time. They are automatically adjusted according to the aircraft's current
location and status.
Failsafe RTH
If the Home Point was successfully recorded, GPS signal is strong and the compass is functioning
normally, Failsafe RTH will be automatically activated if the wireless signal is lost for a specified amount of
time (three seconds when using the remote controller and 20 seconds when using Wi-Fi). The user may
cancel Failsafe RTH to regain control when the wireless signal connection is reestablished.
RTH Procedure
1. Home Point is recorded automatically.
2. RTH procedure is triggered i.e., Smart RTH, Low-Battery RTH and Failsafe RTH.
3. Home Point is confirmed and the aircraft adjusts its orientation.
4. a. The aircraft will ascend to the pre-set RTH attitude and then fly to the Home Point when the aircraft is
further than 20 m from the home point.
b. When the aircraft is between 3 m and 20 m from the Home Point, it will land automatically with the
RTH at Current Altitude option disabled (the default setting in DJI GO 4).
The aircraft will return to the Home Point at the current altitude with the RTH at Current Altitude option
enabled if flying at or above 2.5 m, and it will ascend to 2.5 m then return to home if flying lower than
