The issue that intrigues me, is that every aviation regulatory body for every country in the world which allows Airbus to fly into it's airspace subscribes to the infallibility and redundancy of the Airbus Alpha floor protection system.
Otherwise the performance figures based on 1.12Vs (versus 1.3Vs of all standard flight control variants) wouldn't be accepted as the basis for the certified flight manual performance figures.
Alpha floor is part of the autothrust system.
Autothrust is not required for dispatch.
The flight manual performance figures are not dependant on the availability of Alpha floor, which is not available when dispatching without Autothrust.
