1.4 Compass Calibration
Before start using your FlySense AoA, the device compass should be calibrated. This only
needs to be done once. Please note that compass calibration must be performed with the aircraft
in a parking position on the ground, and never during a flight. Moreover, this calibration
procedure must be performed with the FlySense AoA as close as possible to the final installation
position in order to compensate for parasitic magnetic fields. The exact steps for compass
calibration are outlined below:
Power up your FlySense AoA instrument
Connect a smart device (iOS or Android) to the FlySense AoA wifi Network (no
password needed).
Start the EFIS TA application on the smart device.
Tap on “MENU” button and then “Compass Calib”.
A notification window will pop up, informing you that the calibration procedure is about
to start. Press “Start” to continue.
The application returns back to the main screen with a superimposed calibration window,
indicating the calibration progress (Fig. 4 ) . Start rotating your device slowly, until the
indication on the screen becomes “Good” or “Strong”. To easily achieve the desired
calibration results, start by rotating your device three times around each axis and then
perform a sequence of “lazy eight” maneuvers (Fig. 5).
Press “Close” or wait a few seconds until the calibration window closes automatically.
