Airbus A320 Alpha Floor Protection

The flight controls on the airbus a330 for example are all electronically controlled and hydraulically activated.

Airbus a320 alpha floor protection.

The pfd shows that alpha protection is active in the same way as at low speed and low level. When alpha exceeds alpha prot elevator control switches to alpha protection mode in which angle of attack is proportional to sidestick deflection. If high angle of attack protection is active the bank angle is limited to. Oeb 48 abnormal v alpha prot.

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. 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 aircraft can also enter alpha protection at high altitude where it protects the aircraft from the buffet boundary. High angle of attack protection alpha.

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. Airbus aircraft designs after the a300 a310 are almost completely controlled by fly by wire equipment. These newer aircraft including the a320 a330 a340 a350 and a380 operate under airbus flight control laws.

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