home. During ight, avoid ying over water surfaces until reaching an area
with strong GNSS signal. The altitude above the ground should be greater
than 2 meters and less than 30 meters, otherwise, the aircraft may not be able
to return to the home point. If the aircraft enters ATTI mode before reaching
the area with strong GNSS signal, the home point will be invalidated.
◇
If the vision positioning is not available during ight, the aircraft cannot return
to the home point. Pay attention to the environment according to the App
voice prompts to prevent collisions.
◇
When the aircraft returns to the vicinity of the takeo point and the App
prompts when the current environment is complex, please conrm whether to
continue ying:
»
You need to conrm whether the ight path is correct and pay attention to
ight safety.
»
You need to conrm whether the lighting condition is sucient 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 conrmation, 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 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.
Terrain Data
When the remote controller is connected to the internet, tap
> > Assist in DJI Pilot 2,
and enable Terrain Data, the remote controller will automatically download the elevation
database to the aircraft. Based on the terrain data, the aircraft can plan an optimal ight
path to bypass obstacles along the path during RTH.
When terrain data is enabled,
• if the environment or lighting conditions are suitable for the vision system, the aircraft
will automatically plan an optimal ight path based on the terrain data and the data
