Airbus A320 Alpha Floor Protection

The alpha protection officially called the high angle of attack protection is not only a feature of the a330 but also a320 a340 a350 and a380 and it s one of the five main protections that airbus introduced to keep the flight safely insid.

Airbus a320 alpha floor protection.

The flight controls on the airbus a330 for example are all electronically controlled and hydraulically activated. The alpha floor function is not available below 100 feet ra or during single engine operation with flaps at conf 1 or greater. The aircraft can also enter alpha protection at high altitude where it protects the aircraft from the buffet boundary. If high angle of attack protection is active the bank angle is limited to.

Alpha floor protection is inhibited in some cases. Oeb 48 abnormal v alpha prot. High angle of attack protection alpha. Alpha floor is also triggered if the pilot applies a large aft stick input while either pitch attitude or angle of attack protection is active.

The amber and black strip rises to the actual speed of the aircraft. The pfd shows that alpha protection is active in the same way as at low speed and low level. Alpha max will not be exceeded even if the pilot applies full aft deflection. The speed speed speed voice alert repeats every 5 seconds while the condition exists.

A low energy warning alerts pilots when airplane energy is insufficient to achieve a climbing flight path through pitch control alone.
