J.O. I'm simply talking about keeping the wing tips and tail a safe distance from the ground.

Say that safe distance is 3 feet. If the wing tip gets to say 2.5 feet, the Flight Control Computer (or whatever Airbus call it) makes it's own input to restore the wing tip back to 3 feet. It's no different to limiting the bank angles at higher altitudes only the values are reduced. Perhaps when this kind of input is being made by the computer the pilot can be informed with some kind of annunciation or sound.

Surely the safe operating envelope can be made to reduce as the RA passes from say 20 feet to touchdown. We're simply talking about a computer program aren't we?

O.K. What would happen if at circuit altitude, you try to maintain the bank angle right on the aircraft's limit with the control stick and then induce further roll through rudder or thrust asymmetry? Would the computer simply make an aileron input that brings the roll back to within it's limits?

I have never flown Airbus so these are sincere questions.
