Figure 8: AoA visual indicator explanation.
AoA's visual indicator consists of a color-bar that is composed of three (3) areas as shown above:
•
Green area, which signifies normal aircraft flight attitude.
•
Yellow area, which signifies higher AoA; the higher in the yellow area, the closer to stall
angle the aircraft is.
•
Red area, which depicts critical angle that ranges from 2° before stall and the actual stall
angle.
The upper side of the red area represents the stall angle as stored during calibration procedure.
Accordingly, the border between the red and yellow represents the calibrated warning angle.
For visual indication purposes, FlySense AoA PRO uses a moving white pointer on the color-bar
that indicates the actual AoA. This is illustrated below in Figure 9 that shows three (3) example
cases of AoA during flight. The case in Figure 9(c) is a critical case, where the aircraft is close to
stall attitude.Figure 9: (a) AoA Normal area. (b) AoA warning area. (c) AoA critical area.
