9.9.1. Level Calibration
Step 2
Step 3
Step 1
When flying in Trainer mode or Auto-Level mode, A3S3 needs to know the angle of the plane in both roll and pitch direction,
this is achieved by calculating the attitude of its own. A small angle deviation caused by installation can lead to an
unexpected behavior when flying in Trainer mode or Auto-Level mode. For this reason, a level calibration is recommended
to offset the error caused by installation and to establish a proper level reference of your plane after installing the gyro.
The calibration can be done by manually modifying the offset values in roll and pitch direction or performing an automatic
calibration. Usually the calibration only has to be performed once after installation.
Before calibrating, the plane should be placed on the horizontal ground and make the wing parallel to the
ground. Make the plane slightly nose-up because a certain elevation angle is usually required to maintain
level flight for most planes.
Click the “Level Calibration” button to start the calibration, it will take you several seconds and the LED will
blink blue rapidly during calibrating. Don’t move the plane and keep its attitude until the calibration is done.
After a successful calibration, the new offset values will be displayed on the screen and you can adjust them
manually in the future. In addition, a rapid red blinking is used to indicates that the result exceeds the
maximum permissible value (i.e.
±
25deg), in this case, you have to re-install the gyro to reduce the
deviation caused by installation.
