You need to conrm whether the lighting condition is sucient for the
vision system. If not, the aircraft may exit RTH. Forcing the aircraft to
continue RTH or ight may cause it to enter ATTI mode.
◇
After conrmation, the aircraft will continue to return to the home point at a
low speed. If an obstacle appears on the return path, the aircraft will brake
and may exit RTH.
◇
This RTH process does not support dynamic obstacle detection (including
pedestrians, etc.) and does not support obstacle detection in textureless
scenes such as glass or white walls.
◇
This RTH process requires the ground and nearby environments (such as
walls) to have rich textures and no dynamic changes.
• When the environment or lighting conditions are not suitable for the vision
system:
◆
If the RTH distance is further than 50 meters, the aircraft will return to home
according to the Preset.
◆
The aircraft lands immediately if the RTH distance is less than 5 m.
RTH Settings
RTH settings are available for Advanced RTH. Go to the camera view in DJI Fly, tap >
Safety, and scroll to Return to Home (RTH).
• Optimal:
◆
If the lighting is sucient and the environment is suitable for the vision system,
the aircraft will automatically plan the optimal RTH path and adjust the altitude
according to environmental factors, such as obstacles and transmission signals,
regardless of the RTH Altitude setting. The optimal RTH path means the aircraft
will travel the shortest distance possible to reduce the amount of battery power
used and to increase ight time.
◆
If the lighting is insucient or the environment is not suitable for the vision
system, the aircraft will perform Preset RTH based on the RTH Altitude setting.
