High AOA Protection (dynamic)
Fig. 18 shows that the high AOA protection operates precisely even in dynamic maneuvers, such as the side stick full back step input at VCAS = 180kts.
The aircraft reacts with a ∆nZ =0.8g pitch up movement up to 22° pitch attitude.
The high AOA protection counters this dynamic nose-up maneuver with a 4° nose down elevator command.
The aircraft stabilizes at α= αlim and VCAS = Vαlim.
In neither of the high AOA protection tests the maximum angle-of-attack αlim has been exceeded.
