Return-to-home or RTH is one of the most misunderstood features of any DJI drones, including the DJI Mavic Air 2. In this video, we explain how it works, how you should set it up, how the return-to-home altitude works.

There’s 3 types of RTH
- Smart RTH
- Low Battery RTH
- Failsafe RTH

We talk about the home point and how it's defined and how you can change it in flight.

Smart RTH is initiated by the user with either the app button or by pressing the RTH button on the controller.
Two different modes
- Straight line RTH
- Power Saving RTH

Power saving RTH
If during Straight Line RTH the distance is too far and the altitude is too high, Power Saving RTH will trigger automatically.

Low Battery RTH
Triggered when the battery is too low.
A warning will appear and start to return home after 10 seconds.
It can be canceled anytime. If canceled, the UAS will start to auto-land automatically when the battery is too low. You can still be controlled during auto-land.

Failsafe RTH
If a Home Point was recorded, Failsafe RTH activates if no signal is received for more than 11 seconds. The UAS will move back 50 feet and then…

Obstacle Avoidance during RTH
During climbing, the front and rear sensor sense obstacles. The aircraft will fly backward or forward as necessary to avoid obstacles before continuing to ascend. No avoidance on the side or at the top. Nothing happens if obstacle is sensed from behind

If no GPS signal, the aircraft will hover. If forward and backward vision INOP, no obstacle avoidance. You can manually control the speed of the aircraft during RTH

If there is a GEO zone during RTH, the aircraft will descend until out of the GEO and then come back OR It will hover. Wind still has an effect on RTH.
