RTH Trigger Method
Suitable Lighting and Environ-
ment Conditions
(The aircraft can bypass obsta-
cles and GEO zones)
Unsuitable Lighting and Envi-
ronment Conditions
The user actively
triggers RTH
The aircraft will execute RTH
based on the RTH setting:
• Optimal
• Preset
Preset (The aircraft can ascend
to bypass obstacles and GEO
zones)
Aircraft low battery
Loss of remote con-
troller signal
Original route RTH,
Preset RTH will be executed
when the signal is restored (The
aircraft can bypass GEO zones
and will brake and hover if
there is obstacle)
If the takeo environment is complex (e.g., weak GNSS signal), the aircraft will
automatically update the home point during takeo if the lighting is sucient for the
vision systems. When RTH is triggered, the aircraft will return to the position with strong
GNSS signal based on the RTH settings Optimal or Preset. It will approximately follow the
outbound trajectory back to the vicinity of the home point. At this time, pay attention to
the app prompts and choose whether to let the aircraft automatically RTH and land or to
manually control the RTH and landing.
Landing Protection
During RTH, landing protection activates once the aircraft begins to land.
The specic performance of the aircraft is as follows:
• If the ground is determined suitable for landing, the aircraft will land directly.
• If the ground is determined unsuitable for landing, the aircraft will hover and wait for
pilot conrmation.
• If landing protection is not operational, DJI Fly will display a landing prompt when the
aircraft descends to 0.5m from the ground. Tap Conrm or push the throttle stick all
the way down and hold for one second, and the aircraft will land.
• After reaching the area above the Home Point, the aircraft will land precisely
on the takeo point. Performing a precision landing is subject to the following
conditions:
◆
The Home Point must be recorded upon takeo and must not be changed
during ight.
