A3 Functions
Compass Calibration
Ensure the compass is calibrated before every flight. Failure to calibrate may lead to poor flight performance
or a crash.
1.DO NOT attempt to calibrate your compass where there is a chance of strong magnetic interference.
This includes areas where there are massive metal objects, parking structures, steel reinforcements
underground, or under bridges.
2.DO NOT carry ferromagnetic materials with you during calibration, such as keys or mobile phones.
3.The compass should always be calibrated when moving from indoor spaces to outdoor spaces.
4.After successful calibration, the compass may become abnormal when you place the aircraft on the
ground. This may be because of underground magnetic interference. Move the aircraft to another location
and try again.
Calibration Procedures
Choose an open space to carry out the following procedures.
Using the remote controller (Lightbridge 2 is used here as an example):
1.Quickly flip the control mode switch from P mode to A mode, and then back to P mode three times, and
the Aircraft Status Indicator will display a solid yellow light. Flip the control mode switch between position-1
and position-3 when using the third party remote controllers.
2.Hold and rotate the aircraft horizontally 360 degrees, and the Aircraft Status Indicator will display a solid
green light.
3.Hold the aircraft vertically with nose pointing downward, and rotate it 360 degrees around the center axis.
Recalibrate the compass if the Aircraft Status Indicator is solid red.
Using DJI GO (Lightbridge 2 is required):
Tap the Aircraft Status Indicator bar in the DJI GO app and select “Calibrate”, then follow the on- screen
instructions.
- If the Aircraft Status Indicator blinks red and yellow after the calibration, move your aircraft to a different

When to Recalibrate
1.When compass data is abnormal, and the Aircraft Status Indicator is blinking red and yellow.
2.When flying in a new location, or a location that is different from your last flight.
3.When the mechanical structure of the A3/A3 Pro has changed, i.e. the mounting position of the compass
has changed.
When severe drifting occurs in flight, i.e. the A3/A3 Pro does not fly in a straight line.
Flight Functions
Flight Modes
Below flight modes are available. Use the Flight Controller mode switch to change
the flight mode of the aircraft. The details of each flight 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 different 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 is used.
- 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.

Intelligent Flight Modes (using the Remote Controller)
Intelligent Flight Modes make it easier to operate the aircraft. If you are not using a Lightbridge 2 remote
controller, you will need to configure a 3-position switch on the remote controller as the Intelligent Flight
Modes Switch, with each switch position corresponding to one of the following modes: Off, Course Lock,
or Home Lock.
Course Lock
Use Course Lock to lock the current nose direction as the aircraft’s forward direction. The aircraft will move
in the locked direction regardless of its orientation (yaw angle).
Requirements: Compass must be working properly.
How to operate: 1. Fly the aircraft in the direction you wish to lock; 2. Toggle the Intelligent Flight Modes
Switch to the Course Lock position to lock the current nose direction as the aircraft’s forward direction.
How to reset the parameters: Aircraft nose orientation cannot be reset during flight.
How to stop or exit the flight mode: Toggle the Intelligent Flight Modes Switch to the Off position.
Home Lock
Pull the pitch stick backward to move the aircraft toward its recorded Home Point.
Requirements: Home point recorded; P-GPS mode enabled; distance between the aircraft and Home Point
is greater than 5 meters.
How to operate:
1.Fly the aircraft to the target position;
2.Toggle the Intelligent Flight Modes Switch from the Off position to the Home Lock position for more than
three times to record the Home Point (Note: the Intelligent Flight Modes Switch should stop at the Off
position);
3.Flip the Intelligent Flight Modes Switch to the Home Lock position to start the flight. How to reset the
parameter: Parameters cannot be reset during flight.
How to stop or exit the flight mode: Toggle the Intelligent Flight Modes Switch to the Off position.
Lightbridge 2 not only allows you use the DJI GO app to operate the aircraft, but also use Intelligent

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 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.
- 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.
If using the DJI Lightbridge 2, no additional settings are required for the RTH button. If using another
type of remote controller, you must configure the RTH button in DJI Assistant 2.
Smart RTH
Use the RTH button on the remote controller when GPS is available to enable Smart RTH. During the Smart
RTH procedure, the aircraft returns to the last recorded Home Point but you may control the aircraft's
orientation to avoid collisions. Press the Smart RTH button once to start the process. Press the Smart RTH
button again to exit Smart RTH and regain the control.

FOXTECH GAIA 160MP User Manual

Low Battery RTH with LiPo battery
The low voltage failsafe is triggered when the DJI LiPo Battery is depleted to a point that may affect the
safe return of the aircraft. Users are advised to return home or land the aircraft immediately when these
warnings are shown. Aircraft will automatically return to the Home Point if no action is taken after 10 seconds
countdown. Cancel the RTH procedure by pressing once on the RTH button. The thresholds for these
warnings are automatically determined based on the current aircraft altitude and its distance from the Home
Point.
Aircraft will land automatically only if the current voltage can support the aircraft in landing on the ground
from the current altitude. Use the remote controller to control the aircraft’s orientation during the landing
process.
When the critical battery level warning activates and the aircraft is descending to land automatically,
you may push the throttle upward to hover the aircraft and navigate it to a more appropriate location for
landing.
Attitude Control When One Motor Output Fails
For multirotor aircraft, the A3/A3 Pro flight control system can control the aircraft’s attitude when one motor
fails:
1.During flight, the aircraft with A3/A3 Pro flight control system is attitude controllable when one motor
output fails
2.The motor will not start before take-off. (DJI Intelligent ESCs are required for communication.) Select
Course Lock or Home Lock mode to fly the aircraft to a safe area to land when the aircraft is far away, or
the attitude can’t be recognized.
Propulsion System Protection
Low voltage and overweight aircraft warnings are provided in the DJI GO app.
