What happens is pilot hits toga, follows SRS even if it requires full back stick and survives the sim scenario. Emphasis being on "pilot".
Dear certain PPRuNers, you are mixing up alpha floor and alpha prot. Despite both having "alpha" in their names, they're quite different animals. Alpha prot is function of FBW that limits AoA, alpha floor is automatic setting of TOGA thrust regardless of power levers position. As long as normal law is alive and kicking, alpha prot is available, but alpha floor can be deactivated through autothrust deactivation (this is not mere disconnection). The horror scenario described in the previous post may end up in aeroplane hitting the ground (or trees) at very high angle of attack and engines at idle, but it can not end up in stall. And I don't merely think that fully operational A320 can't stall due to alpha prot - that it can't is a fact and not an opinion.
