Figure 4: (a) Press “Start” to start compass calibration. (b) Calibration in progress. The
calibration results are indicated as “Weak”; you should continue rotating your device until you
have a “Good” or “Strong” indication. (c) Indication as “Strong” calibration signifies that the
device’s compass has been properly calibrated.
Fig. 5: To easily calibrate the Compass start by slowly rotating FlySense AoA PRO three times
around each axis and then perform a sequence of “lazy eight” maneuvers until you have a
“Good” or a “Strong” indication on the EFIS TA app.
1.5 AHRS Leveling
As already stated above, the FlySense AoA PRO should ideally be mounted parallel to the
symmetry axes of the airplane. Since this cannot always be accurately performed, AHRS leveling
is important in order to adjust for minor inaccuracies during placement.
The “AHRS leveling” procedure described below needs only to be done once, after you have
mounted and fully connected FlySense AoA PRO. Please note that AHRS leveling must be
performed with the aircraft in a parking position on the ground, and never during a flight.
