Apr 15, 2024 · V Alpha prot Speed: It is the speed at which angle of attack protection becomes active. It is represented by the top of a black and amber strip along the PFD speed scale, in …

Maneuvre Protection, also called Maneuvre Protection, enables immediate PF reaction, by pulling the sidestick to full aft without any risk of over stressing the aircraft. The load factor limit is:- …

The PFD airspeed scale is modified: V LS remains displayed; V ALPHA PROT and V ALPHA MAX are removed; They are replaced by a red and black barber pole, the top indicating the …

Feb 1, 2024 · Vα PROT, Vα MAX and VSW are computed by the FAC, based on aerodynamic data. They are only used for display on the PFD, and not for flight control protection (the …

When alpha exceeds alpha prot, elevator control switches to alpha protection mode in which angle of attack is proportional to sidestick deflection. Alpha max will not be exceeded even if …

Load factor protection enables immediate PF reaction, without any risk of overstressing the aircraft. An immediate 2.5g reaction provides larger obstacle clearance, than a hesitant & …

Apr 30, 2015 · The speed that equates to Alpha Prot (Va PROT) is displayed as the top of a black and amber strip on the PFD speed scale. If no input is made on the sidestick, the aircraft will …

Valpha prot and Valpha max are current AOA measured by two active valid AOA probes and averaged. It is converted to speed and shown on PFD. They are load factor sensitive so vary …

The title refers to the most visible effect that the flight crew will see on the PFD, if AOA values are erroneous. It consists in an Abnormal behavior of the V Alpha Prot, and its associated strip. …

May 28, 2019 · When high angle of attack protection is active the side stick controls angle of attack (alpha protection to alpha max), so far so good. In several places throughout the FCOM …
