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 aircraft designs after the a300 a310 are almost completely controlled by fly by wire equipment. Oeb 48 abnormal v alpha prot. The speed speed speed voice alert repeats every 5 seconds while the condition exists. The alpha floor function is not available below 100 feet ra or during single engine operation with flaps at conf 1 or greater.

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. A low energy warning alerts pilots when airplane energy is insufficient to achieve a climbing flight path through pitch control alone. Alpha floor protection is inhibited in some cases.

These newer aircraft including the a320 a330 a340 a350 and a380 operate under airbus flight control laws. The flight controls on the airbus a330 for example are all electronically controlled and hydraulically activated. If high angle of attack protection is active the bank angle is limited to. The pfd shows that alpha protection is active in the same way as at low speed and low level.
