Failsafe Rth; Rth Safety Precautions; Obstacle Sensing During Rth - dji MATRICE 350 RTK User Manual

Failsafe RTH

Failsafe RTH is automatically enabled when the remote controller signal is lost for more than six
seconds. RTH is the default failsafe action in the app.
Failsafe RTH includes two stages: Original Route RTH and Smart RTH. When Failsafe RTH is
enabled, the aircraft will fly to the Home Point on its original flight route for a maximum distance
of 50 m (164 ft), during which it will try to reconnect to the remote controller. If the aircraft cannot
reconnect to the remote controller within 50 m (164 ft) or detects obstacles during RTH, the
aircraft will exit Original Route RTH and enter the Smart RTH stage. The aircraft will remain in RTH
mode even after the remote controller signal is restored. The user can use the remote controller
to control the aircraft's flight speed and altitude, and exit RTH by pressing the RTH button on the
remote controller.

Obstacle Sensing during RTH

The aircraft can sense and avoid obstacles during RTH if the lighting is sufficient for obstacle
sensing. The obstacle sensing procedure is as follows:
1. The aircraft decelerates when an obstacle is sensed at approximately 20 m (65.62 ft) ahead.
2. The aircraft stops and hovers, then ascends to avoid the obstacle. Eventually, the aircraft
stops ascending when it is at least 5 m (16.4 ft) above the detected obstacle.
3. The aircraft continues flying to the Home Point at its current altitude.
The aircraft cannot avoid obstacles during RTH when the forward
vision system is disabled. However, the user can still control the
speed and the altitude of the aircraft with the remote controller if
a signal is available.Therefore, it is important to set a suitable RTH
altitude before each flight. Launch DJI Pilot 2, enter the Preflight

altitude.
If RTH is triggered when the aircraft is below 20 m (65 ft), the
aircraft will automatically ascend to 20 m (65 ft) from the current
20m
altitude. The vertical speed can be adjusted using the throttle stick
H
during ascent with a maximum descent speed of 1 m/s and ascent
speed of 3 m/s.
The RTH feature will be disabled when the GNSS signal is weak, or
the GNSS is unavailable.
