When to Recalibrate
1. When compass data is abnormal, and the Aircraft Status Indicator is blinking red and yellow.
2. When ying in a new location, or a location that is dierent from your last ight.
3. When the mechanical structure of the A3/A3 Pro has changed, i.e. the mounting position of
the compass has changed.
4. When severe drifting occurs in ight, i.e. the A3/A3 Pro does not y in a straight line.
Flight Functions
Flight Modes
Below ight modes are available. Use the Flight Controller mode switch to
change the ight mode of the aircraft. The details of each ight mode are
found in the section below.
Lightbridge 2 is used here as an example.
P mode (Positioning): P mode works best when GPS signal is strong. There are three dierent
states of P mode, which will be automatically selected by the A3/A3 Pro depending on GPS
signal strength and Vision Positioning sensors:
P-GPS: GPS and Vision Positioning both are available, and the aircraft is using GPS for
positioning.
P-OPTI: Vision Positioning is available but the GPS signal is not. Aircraft is using only Vision
Positioning for hovering
P-ATTI: Neither GPS or Vision Positioning available, aircraft is using only its barometer for
positioning, so only altitude is controlled.
A mode (Attitude): The GPS and Vision Positioning System is not used for holding position. The
aircraft only uses its barometer to maintain altitude. If it is still receiving a GPS signal, the aircraft
can automatically return home if the Remote Controller signal is lost and if the Home Point has
been recorded successfully.
F mode (Function): Intelligent Flight Mode is activated in this mode.
M mode (Manual): The GPS and Vision Positioning System is not used for holding position. No
barometer is used to maintain altitude. Only use M mode in case of an emergency.
P-OPTI mode is only available when a DJI Vision Positioning System (e.g. DJI
GUIDANCE) is used. Refer to the DJI GUIDANCE user manual for more details about
how to use P-OPTI mode.
Once the GPS signal is recovered, or the Vision Positioning System available, the Flight
Control System can re-enter P-GPS mode or P-OPTI mode.
M mode (Manual) should be enabled in DJI Assistant.
