Protection Functions - dji A3 User Manual

Lightbridge 2 not only allows you use the DJI GO app to operate the aircraft, but also
use Intelligent Flight Modes, such as Course Lock, Home Lock, Point of Interest (POI)
and Waypoints, to capture professional shots during flight.

Protection Functions

Return to Home
Return to Home (RTH) brings the aircraft back to the last recorded Home Point. There are three
cases that will trigger the RTH procedure; they are Failsafe RTH, Smart RTH and Low Battery
RTH with the DJI Intelligent Battery (Low Voltage RTH with a LiPo battery).
Failsafe RTH
Failsafe RTH is activated automatically if the remote controller signal (including video relay signal if
DJI Lightbridge 2 used) is lost for more than 3 seconds, provided that the Home Point has been
successfully recorded and the compass is working normally. The RTH process may be interrupted
and the operator can regain control over the aircraft if a remote controller signal is resumed.

Flashing Green
4 Signal Lost Lasts 3secs.
Flashing Yellow Rapidly
The aircraft automatically descends and lands if RTH is triggered when the aircraft flies
within a 65-foot (20-meter) radius of the Home Point.
The aircraft cannot return to home if the LED is slowly blinking yellow or the GPS does
not work.
The aircraft cannot avoid obstacles during Failsafe RTH. Therefore it is important to
set a reasonable Failsafe altitude before each flight. Launch the DJI GO app and enter
"Camera" view and select "MODE" to set the Failsafe altitude.
The aircraft will stop ascending and immediately return to the Home Point if you move
the throttle stick when the aircraft reaches an altitude of 20 m or above during Failsafe.
