VOL. II, 27.3.4.5 Alpha Protection
FLTCTR_05
Describe the protections provided in normal law.
Alpha Protection
Alpha protection limits the aircraft’s angle of attack (alpha).
- This allows the pilot to safely command a maximum angle of attack for critical maneuvers such as windshear recovery and GPWS “pull up” maneuvers without the danger of stalling the aircraft.
- The range where alpha protection is active is displayed on the airspeed indicator as a black and amber band.
- The top of the band is referred to as alpha prot (alpha protection),
- and the base of the band as alpha max (alpha maximum).
Alpha max is an angle of attack slightly less than the stall angle of attack.
- At alpha max, the aircraft will not stall but will have nearly the maximum allowable lift for the current weight and configuration.
If the angle of attack exceeds alpha prot:
- the autopilot(s) disconnect,
- the speedbrakes retract (the handle does not move),
- and the sidestick control switches from g load demand to angle of attack demand.
Between alpha prot and alpha max, sidestick pitch displacement directly and proportionally commands angle of attack.
- If the sidestick is held full aft, the aircraft will vary pitch to maintain alpha max.
- If the sidestick is released to neutral the aircraft will vary pitch to maintain alpha prot.
- Sidestick movement forward of neutral is required to leave alpha protection mode and return back to the normal g load demand mode.
