SAFETY NOTE: It is highly recommended that, for safety reasons and in order to achieve
proper calibration, a second person (e.g. co-pilot) performs the calibration procedure while the
Pilot-in-Command flies the aircraft in a safe manner at altitude, while also maneuvering the
aircraft.
AoA calibration procedure is performed according to the following 2 steps.
Step 1:
Click
on EFIS TA app “MENU” → “Miscellaneous” → “Calibrate AoA” option. This
will bring up the window shown below in Figure 7(a); a value -1.0 in the mid-right part of the
window signifies uncalibrated FlySense AoA PRO.

Figure 7: (a) Uncalibrated FlySense device. (b) Calibrated FlySense device (i.e. stall angle has
been determined at 12° and accordingly warning angle has been set at 10°).
Step 2:
While in flight mode, gradually reduce aircraft speed, until stall buffet is reached and press
the “Set AoA Warning” button. This will automatically determine and store the aircraft's stall
angle and will set the warning angle at a value of two degrees (2°) less. In the example case shown
above in Fig 7(b), stall angle has been determined at 12° and accordingly warning angle has been
set at 10°.
Angle of Attack operation
The Angle of Attack feature in FlySense AoA PRO offers both visual AoA indication as well as
aural warning signal. The visual indication is illustrated in Figure 8 and also detailed below.
