Return to Home
The Return to Home (RTH) function brings the aircraft back to the last recorded Home Point
when the positioning system is functioning normally. There are three RTH modes: Smart RTH,
Low Battery RTH, and Failsafe RTH. The aircraft will automatically fly back and land at the Home
Point when Smart RTH is initiated, the aircraft enters Low Battery RTH, or the signal between the
remote controller and the aircraft is lost. RTH will also be triggered in other abnormal scenarios
such as where video transmission is lost.
GNSS
Description
Home
Point
10
The first location where the aircraft receives a strong to moderately
strong GNSS signal (indicated by a white icon) will be recorded as the
default Home Point. It is recommended to wait until the Home Point is
successfully recorded before flying. After the Home Point is recorded,
a prompt will appear in DJI Fly. The Home Point can be updated before
takeoff as long as the aircraft receives another strong to moderately
strong GNSS signal. If the signal is weak, the Home Point will not be
updated. If it is necessary to update the Home Point during a flight
(such as where the user’s position has changed), the Home Point can
be manually updated in Safety of System Settings on DJI Fly.
Smart RTH
If the GNSS signal is sufficient, Smart RTH can be used to bring the aircraft back to the Home
Point. Smart RTH is initiated either by tapping
in DJI Fly or by pressing and holding the RTH
button on the remote controller. Exit Smart RTH by tapping
in DJI Fly or by pressing the RTH
button on the remote controller.
Low Battery RTH
When the Intelligent Flight Battery level is too low and there is not enough power to return
home, land the aircraft as soon as possible. Otherwise, the aircraft will fall when it runs out of
power, resulting in the aircraft being damaged and other potential hazards.
To avoid unnecessary danger due to insufficient power, DJI Mini 3 will intelligently determine
whether the current battery level is sufficient to return home based on the current location. A
warning prompt will appear in DJI Fly when the battery level is low and only enough to complete
an RTH flight.
The user can cancel RTH by pressing the RTH button on the remote controller. If RTH is
cancelled following a low battery warning, the Intelligent Flight Battery may not have enough
power for the aircraft to land safely. As a result, you may crash or lose your aircraft.
The aircraft will automatically land if the battery level is extremely low. Auto landing cannot be
canceled but the remote controller can be used to alter the horizontal movement and the speed
of descent of the aircraft during landing.
The aircraft will land automatically if the battery level will only last long enough to directly
descend and land from its current altitude. The action cannot be canceled but the remote
controller can be used to alter the horizontal movement of the aircraft.
