The RTH plan in dierent environments, RTH trigger methods, and RTH settings is as follows:
Lighting and Environment Conditions
RTH Trigerring Conditions
Suitable for Vision System Unsuitable for Vision System
The aircraft can bypass
obstacles and avoid GEO
Zones and custom GEO
Zones (user-dened no-y
zones).
The aircraft cannot bypass

The user actively triggers
RTH
The aircraft will perform RTH
based on RTH setting:
• Optimal RTH path
• Preset RTH path
Preset RTH path
Aircraft low battery
Loss of control signal
Original route RTH procedure,
preset RTH path will be
performed when the signal is
restored
• During Advanced RTH, the aircraft will adjust the flight speed automatically to suit
environmental factors such as wind speed and obstacles.
• The aircraft cannot avoid small or fine objects such as power lines or towers. It is
recommended to disable Optimal Route Planning. Make sure to set the RTH Altitude
higher than all obstacles.
• It is recommended to mark the waypoint with obstacle above as no-return point to
ensure the ight safety during RTH.
• DO NOT update the Home Point after gaining control using remote controller B.
Otherwise, the aircraft may not return to the dock if the Home Point is updated.
• If the max altitude is set below the current altitude during RTH, the aircraft will
descend to the max altitude rst and then continue to return to home.
• The RTH Altitude cannot be changed during RTH.
• If there is a large dierence in the current altitude and the RTH altitude, the amount
of battery power used cannot be calculated accurately due to wind speeds at dierent
altitudes. Pay extra attention to the battery power and warning prompts in DJI
FlightHub 2.
• During Advanced RTH, if the lighting condition and environment becomes unsuitable
for the vision system and if Obstacle Data is disabled, the aircraft will perform Preset
RTH path. In this case, the aircraft cannot bypass obstacles. Make sure to set an
appropriate RTH altitude before performing RTH.
• If the aircraft reaches the altitude limit of the aircraft current location or of the Home
Point while it is ascending during Preset RTH path, the aircraft stops ascending and
returns to the Home Point at the current altitude. Pay attention to ight safety during
RTH.
