2.5 m when the aircraft is between 3 m and 20 m from the Home Point.
c. The aircraft will land automatically if RTH is triggered and the aircraft is less than 3 m from the home
point.
5. The aircraft will hover 0.3 m above ground and wait for confirmation from the user. The aircraft will land
and stop its motors after user confirmation.

The aircraft cannot return to the Home Point when GPS signal is weak or unavailable.
It is important to set a suitable Failsafe altitude before each flight. Launch the DJI GO 4 app, tap
"GO FLY" and tap
The aircraft will stop ascending and immediately return to the Home Point if you move the
throttle stick in the aircraft reaches 65 feet (20 meters) altitudes or beyond during Failsafe.
Obstacle Avoidance during RTH
Spark will Return to Home at a flight speed of 10 m/s and cannot avoid obstacles when RTH is triggered and
the aircraft is further than 100 m from the home point.
Spark can sense and actively attempt to avoid obstacles during RTH, provided that lighting conditions are
adequate enough for the 3D Sensing System and RTH is triggered when the aircraft is less than 100 m from
the Home Point. Upon detecting an obstacle, the aircraft will act as follows:
1. The aircraft decelerates when an obstacle is sensed at 16 ft (5 m).
2. The aircraft stops and hovers then starts flying backward until the 3D Sensing System cannot sense any
obstacles.
3. The aircraft ascends vertically for about five seconds.
4. RTH procedure resumes. The aircraft will continue flying to the Home Point at the current altitude.
