Return to Home (RTH) Logic

There are the 3 types of RTH: Smart RTH, Low Battery RTH, and Failsafe RTH.

All DJI drones support these three RTH logics, but different aircraft have different performances during RTH.

Take DJI Mini 3 Pro as an example:

Smart RTH

The Home Point is recorded when the aircraft receives a strong GNSS signal.

Smart RTH is initiated either by tapping the “H” button in DJI Fly or pressing and holding the RTH button on the remote controller.

The RTH route is different based on the RTH distance. The aircraft will determine whether to return the Home Point at the current altitude according to the current altitude. As there are some differences in the RTH logic of specific drones, please refer to “Return to Home" in the User Manual.

* The aircraft will land immediately if it is less than 5 m from the Home Point when RTH begins. Please pay attention to the position of the aircraft during RTH, and avoid landing on the water or lake surface.

Exit RTH by tapping the “x” icon in DJI Fly or by pressing the RTH button on the remote controller. After exiting RTH, you will regain control of the aircraft.

Low Battery RTH

The aircraft will determine whether the current battery level is sufficient for returning home based on the current location, surrounding environment, and real-time wind speed.
If the current battery level is only enough to complete an RTH flight, a warning prompt will appear in DJI Fly.

1.  Exit RTH by tapping the “x” icon in DJI Fly or by pressing the RTH button on the remote controller. After exiting RTH, you will regain control of the aircraft.
2. The aircraft will land automatically if the current battery level can only support the aircraft long enough to descend from the current altitude. Auto landing cannot be canceled but the remote controller can be used to control the horizontal movement by pushing the pitch and roll sticks when the remote controller signal is strong. Please move the aircraft horizontally to find an appropriate place to and as soon as possible.

Failsafe RTH

1.  The Home Point is recorded when the aircraft receives a strong GNSS signal.
2.  In the DJI Fly app, enter the camera view and go to “System Settings”, “Safety”, “Advanced Settings”, and set “Signal Lost” to “Return to Home”.

The remote controller signal is lost for more than three seconds.

* The time of different models varies. For details, please refer to “Return to Home " in the User Manual.

The drone returns to the Home Point based on its original flight route.

Notes

1.  When the lighting is not sufficient for vision systems (e.g. flying at night), the drone cannot avoid obstacles.

2.  The drone may enter ATTI mode and automatically land when the GPS signal is poor or lost.

3.  GEO zones may affect the RTH. Avoid flying near GEO zones.

4.  The drone may not be able to return to the Home Point when the wind speed is too high. Fly with caution.

 

Tips

1.  Please check the surrounding environment, and it is important to set a suitable RTH altitude in the app before each flight. Make sure that the RTH altitude is higher than the surrounding buildings or mountains (RTH altitude is based on the position of recorded Home Point).

2. Please do not continue to fly the drone after canceling the RTH during Low Battery RTH. Otherwise, the aircraft will be forced to land due to critical low battery level.
