The aircraft cannot avoid obstruction during the Failsafe RTH when the
Forward Vision System is disabled. Therefore, it is important to set a
suitable Failsafe altitude before each ight. Launch the DJI GO 4 app,
enter “Camera” and tap to set the Failsafe Altitude.

If the aircraft is ying under 65 feet (20 meters) and Failsafe (including
Smart RTH, Lower Battery RTH ) is triggered, the aircraft will first
automatically ascend to 65 feet (20 meters) from the current altitude. You
can only cancel the ascending by exiting the Failsafe.

Aircraft automatically descends and lands if RTH is triggered when the
aircraft ies within a 65 feet (20 meters) 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 65 feet (20 meters) altitudes or beyond
during Failsafe.

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

if you move the left stick after the aircraft rises above 65 feet (20
meters) 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 obstacles during RTH, provided that the lighting
conditions are adequate for the Forward Vision System. Upon detecting an obstacle, the aircraft will act
as follows:
1. The aircraft will use the primary camera to identify obstacles as far as 984 feet (300 meters) in front,
allowing it to plan a safe route home.
2. The aircraft decelerates when an obstacle is sensed at 49 feet (15 meters) ahead.
3.The 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.
4. Failsafe RTH procedure resume, the aircraft will continue ying to the Home Point at the current
altitude.
