Obstacle Avoidance During RTH
In an optimal operating environment, obstacle avoidance during RTH is available. If there is an
obstacle within 20 m of the aircraft, the aircraft decelerates and then stops and hovers. The
aircraft will exit the RTH procedure and wait for further commands.
If RTH is triggered during Route or Fruit Tree operations, the aircraft will calculate an
RTH path that circumvents obstacles added while planning the task area.
If connection points were added before performing the operation, the aircraft will fly
to the Home Point via the connection points. Connection points cannot be deleted
during the operation. Adjust the connection points after tapping the End button.
Exit automatic RTH and control the aircraft to return to home manually if it is not
necessary to fly through the connection points to return.
Landing Protection Function
Landing Protection activates during auto landing. The procedure is as follows:
1. After arriving at the home point, the aircraft descends to a position 3 m above the ground
and hovers.
2. Control the pitch and roll sticks to adjust the aircraft position and make sure the ground is
suitable for landing.
3. Pull down the throttle stick or follow the onscreen instructions in the app to land the
aircraft.
When using fixed RTK positioning, the aircraft will land directly instead of entering
Landing Protection. Landing Protection is still available if the aircraft is performing a
fruit tree route operation planned using DJI Terra.
Loss of Navigation Systems
When using fixed RTK positioning, the aircraft will switch to GNSS if RTK is unavailable during
flight. If GNSS is also unavailable, the aircraft will switch to Attitude (ATTI) mode automatically to
stabilize its attitude and a prompt will appear in the app to remind users to fly with caution and
land as soon as possible.
Control Station Failures
Control station failures include the following scenarios.
1. Control signal is lost: the aircraft will enter Failsafe RTH if Failsafe RTH is enabled in the
app. Refer to Loss of C2 Link for more information about Failsafe RTH. The aircraft action
can also be set to hovering in place until the aircraft lands with critically low battery level or
landing directly.
