Low Battery RTH
Low Battery RTH is triggered when the Intelligent Flight Battery is depleted to the point that the
safe return of the aircraft may be affected. Return home or land the aircraft immediately when
prompted.
DJI Fly displays a warning when the battery level is low. The aircraft will automatically return to the
Home Point if no action is taken after a 10 second countdown.
The user can cancel RTH by pressing the RTH button or Flight Pause button on the remote controller.
If RTH is cancelled following a low battery level warning, the Intelligent Flight Battery may not have
enough power for the 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. The
aircraft will fly backwards for 50 m on its original flight route, and then enter Straight Line RTH. The
aircraft enters Straight Line RTH if the remote controller signal is restored during Failsafe RTH.
After flying for 50 m:
1. If the aircraft is less than 50 m from the Home Point, it flies back to the Home Point at the
current altitude.
2. If the aircraft is further than 50 m from the Home Point and the current altitude is higher than
the preset RTH altitude, it flies back to the Home Point at the current altitude.
3. If the aircraft is further than 50 m from the Home Point and the current altitude is lower than
the preset RTH altitude, it ascends to the preset RTH altitude and then flies back to the Home
Point.
Obstacle Avoidance During RTH
When aircraft is ascending:
1. The aircraft brakes when an obstacle is sensed from in front and flies backward until a safe
distance is reached before continuing to ascend.
2. The aircraft brakes when an obstacle is sensed from behind and flies forward until a safe
distance is reached before continuing to ascend.
3. The aircraft brakes when an obstacle is sensed from above and flies forward until a safe
distance is reached before continuing to ascend.
4. No operation will occur when an obstacle is sensed below the aircraft.
When aircraft is flying forward:
1. The aircraft brakes when an obstacle is sensed from in front and files backward to a safe
distance. It ascends until no obstacle is sensed and continues to ascend another 5 m and then
