• The aircraft may not be able to return to the Home Point normally if the GNSS signal
is weak or unavailable. The aircraft may enter ATTI mode if the GNSS signal becomes
weak or unavailable after entering Failsafe RTH. The aircraft will hover in place for a
while before landing.
• It is important to set a suitable RTH altitude before each flight. Launch DJI Pilot 2 and
set the RTH altitude. The default RTH altitude is 100 m.
• The aircraft cannot avoid obstacles during Failsafe RTH if the vision systems are
unavailable.
• GEO zones may affect the RTH. Avoid flying near GEO zones.
• The aircraft may not be able to return to a Home Point when the wind speed is too
high. Fly with caution.
• Be aware of small or fine objects (such as tree branches or power lines) or transparent
objects (such as water or glass) during RTH. Exit RTH and control the aircraft manually
in an emergency.
• RTH may not be available in some environments even if the vision systems are working.
The aircraft will exit RTH in such cases.
Landing Protection
Landing Protection will activate during Smart RTH. Landing Protection is enabled once the
aircraft begins to land.
1. During Landing Protection, the aircraft will automatically detect and carefully land on
suitable ground.
2. If the ground is determined unsuitable for landing, the aircraft will hover and wait for
pilot confirmation.
3. If Landing Protection is not operational, DJI Pilot 2 will display a landing prompt when
the aircraft descends to 0.5 m from the ground. Tap confirm or push the throttle stick all
the way down and hold for one second, and the aircraft will land.
• Landing protection will not work in the following circumstances:
a. When the downward vision system is disabled.
b. When the user is operating the pitch/roll/throttle stick (landing protection will be re-
activated when the control stick is not in use).
c. When the positioning system is not functioning properly (e.g., position drift errors).
d. When the vision system needs calibrating. When the lighting is too dim for the vision
system to operate.
e. If no valid observation data is obtained and the ground conditions cannot be
detected, the aircraft will descend to 0.5 m above the ground and hover pending
confirmation by the user to land.
