Return to Home
Return to Home (RTH) returns the aircraft to the last recorded Home Point when the positioning system
is functioning normally. There are three types of RTH: Smart RTH, Low Battery RTH, and Failsafe RTH.
The aircraft automatically flies back to the Home Point and lands when Smart RTH is initiated, the
aircraft enters Low Battery RTH, or the video link signal is lost during ight.
GNSS Description
Home
Point
10
The default Home Point is the first location where the aircraft received a
strong to moderately strong GNSS signal where the icon is white. The Home
Point can be updated before takeo as long as the aircraft receives a strong
to moderately strong GNSS. If the GNSS signal is weak then the Home Point
cannot be updated.
Smart RTH
If the GNSS signal is sucient, 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 until it beeps. Exit Smart RTH by tapping
in DJI Fly or by pressing the RTH button
on the remote controller.
Advanced RTH
Advanced RTH is enabled if the lighting is sucient and the environment is suitable for vision systems
when Smart RTH triggered. The aircraft will automatically plan the best RTH path, which will be
displayed in DJI Fly and will adjust according to the environment.
RTH Settings
RTH settings are available for Advanced RTH. Go the camera view in DJI Fly, tap System, Safety, and
then RTH.
1. Optimal: Regardless of the RTH Altitude settings, the aircraft automatically plans the optimal RTH
path and adjusts the altitude according to environmental factors such as obstacles and transmission
signals. The optimal RTH path means the aircraft will travel the shortest distance possible reducing
the amount of battery power used and increasing ight time.
2. Preset: When the aircraft is further than 50 m from the home point when RTH begins, the aircraft
will plan the RTH path, y to an open area while avoiding obstacles, ascend to the RTH Altitude,
and return to home using the best path. When the aircraft is a distance of 5 to 50 m from the home
point when RTH begins, the aircraft will not ascend to the RTH Altitude and instead return to home
using the best path at the current altitude. When the aircraft is near the home point, the aircraft will
descend while ying forward if the current altitude is higher than the RTH Altitude.
Advanced RTH Procedure
1. The Home Point is recorded.
2. Advanced RTH is triggered.
3. The aircraft brakes and hover in place.
a. The aircraft lands immediately if it is less than 5 m from the Home Point when RTH begins.
b. If the aircraft is farther than 5 m from the home point when RTH begins, the aircraft will plan the
best path according to the RTH settings and y to the home point while avoiding obstacles and
GEO zones. The aircraft front will always point in the same direction as the ight direction.
