8. After landing, execute the CSC command or hold the left stick at its lowest position until the motors
stop.
9. Turn o the Intelligent Flight Battery rst, then the remote controller.
When the Aircraft Status Indicators blink yellow rapidly during ight, the aircraft has entered
Failsafe mode.
A low battery level warning is indicated by the Aircraft Status Indicators blinking red slowly or
rapidly during ight.
Watch our video tutorials for more ight information.
Three-propeller Emergency Landing
During flight, if the aircraft lacks one lift output (e.g. propulsion system failure of a motor), it will
automatically switch to the Three-propeller Emergency Landing Mode. The ight controller will try to
maintain the stability and controllability of attitude and velocity, and make the aircraft automatically
descent in this mode. This mode enables a user to land the aircraft onto a safe zone by controlling the
aircraft, helps to reduce the chance for the aircraft and payload to drop, and damage the people and
property on the ground.
When the aircraft enters the Three-propeller Emergency Landing Mode, the remote controller will alert
the user by vibrating. At this time, the aircraft will enter rapid spin and automatically descend by default.
The stick that controls back and forth movement will be adjusted to control the north-south movement
and the stick that controls the left and right movement will be adjusted to control the west-east
movement. The user can operate the sticks to move the aircraft to the appropriate landing area as soon
as possible. When the aircraft reaches near to the ground, user can use the Emergency propeller stop
to land the aircraft to minimize the drop loss caused by the aircraft spin.
Three-propeller Emergency Landing requires that the takeo weight of the aircraft to be less
than 7.7 kg and it should work in open space with the ight height that exceeds 10 m.
Once such a failure occurs, please move the aircraft immediately away from people and
valuables, and land on a level and soft surface (e.g. grass) to reduce damaging the aircraft.
If a propeller is damaged but the motor is still working normally, the aircraft will not enter the
Three-propeller Emergency Landing Mode.
Three-propeller Emergency Landing is only used as an emergency protection function when
the propulsion system fails. Please do not actively trigger it.
Make sure that all rmware is up-to-update.
After landing, contact DJI support for the propulsion system maintenance as soon as
possible.
