Airbus a320 alpha floor protection.

Oeb 48 abnormal v alpha prot. A low energy warning alerts pilots when airplane energy is insufficient to achieve a climbing flight path through pitch control alone. High angle of attack protection alpha. The flight controls on the airbus a330 for example are all electronically controlled and hydraulically activated.

The amber and black strip rises to the actual speed of the aircraft. 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. Alpha floor protection is inhibited in some cases. The pfd shows that alpha protection is active in the same way as at low speed and low level.

These newer aircraft including the a320 a330 a340 a350 and a380 operate under airbus flight control laws. The aircraft can also enter alpha protection at high altitude where it protects the aircraft from the buffet boundary. Alpha max will not be exceeded even if the pilot applies full aft deflection. If high angle of attack protection is active the bank angle is limited to.

The alpha floor function is not available below 100 feet ra or during single engine operation with flaps at conf 1 or greater.
