Airbus a320 alpha floor protection.
High angle of attack protection alpha.
Alpha max will not be exceeded even if the pilot applies full aft deflection.
When alpha exceeds alpha prot elevator control switches to alpha protection mode in which angle of attack is proportional to sidestick deflection.
The aircraft can also enter alpha protection at high altitude where it protects the aircraft from the buffet boundary.
These newer aircraft including the a320 a330 a340 a350 and a380 operate under airbus flight control laws.
Alpha floor protection is inhibited in some cases.
The amber and black strip rises to the actual speed of the aircraft.
The alpha floor function is not available below 100 feet ra or during single engine operation with flaps at conf 1 or greater.
A low energy warning alerts pilots when airplane energy is insufficient to achieve a climbing flight path through pitch control alone.
The flight controls on the airbus a330 for example are all electronically controlled and hydraulically activated.
Airbus aircraft designs after the a300 a310 are almost completely controlled by fly by wire equipment.
If high angle of attack protection is active the bank angle is limited to.
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.
