20米

The aircraft cannot avoid obstruction during the Failsafe RTH when the

Obstacle Sensing System is disabled. Therefore, it is important to set an

suitable Failsafe altitude before each flight. Launch the DJI GO 4 app

and enter “Camera” and select “MODE > Advanced Settings > Failsafe

mode” to set the Failsafe altitude.

20 m

If the aircraft is ying under 20 meters (65 feet) and Failsafe (including

Smart RTH, Lower Battery RTH ) is triggered, the aircraft will first

automatically ascend to 20 meters (65 feet) from the current altitude.

You can only cancel the ascending by exiting the Failsafe. Refer to “RTH

Button” on page 33 for more information on how to exit the Failsafe and

regain the control of the remote controller.

20 m

Aircraft automatically descends and lands if RTH is triggered when the

aircraft ies within a 20 meters (65 feet) radius of the Home Point. Aircraft

will stop ascending and immediately return to the Home Point if you move

the left stick if the aircraft reaches 20 meters (65 feet) altitudes or beyond

during Failsafe.

20米

Aircraft cannot return to the Home Point when GPS signal is weak

( [

] displays grey) or unavailable.

20米

if you move the left stick after the aircraft rises above 65 feet (20m)

but below the pre-set Failsafe RTH altitude, the aircraft will stop

ascending and immediately return to the Home Point.

Obstacle Avoidance During RTH

Aircraft can now sense and actively attempt to avoid obstacle during FailSafe RTH, provided that the

light condition is ideal for the Obstacle Sensing System. The details on how the aircraft will behave during

obstacle avoid is listed below:

1. Aircraft decelerates when an obstacle is sensed at 49 feet (15 meters) ahead.

2. Aircraft stops and hover then start ascending vertically to avoid the obstacle. Eventually, the aircraft will

stop climbing when it is at least 16 feet (5 meters) above the detected obstacle.

3. Failsafe RTH procedure resume, the aircraft will continue ying to the Home Point at the current

altitude.
