As an aside, its interesting to note that should the aircraft go into Rated or Unrated N1, for V2500 powered aircraft, then the Alpha Floor protection is no longer available...

There is also (A-340 anyway) a mode of alpha prot that will stop flap/slat retraction if the aerodynamic loading (bank angle or turbulence eg. during retraction) is excessive. "Alpha Lock" is annunciated and the retaction continues when the conditions are eased.
