Shooting off at a slight tangent, I know that the software protects Airbus from stalling, however lets just say, and we're being very theoretical here, that the software fails, and a complacent crew don't realise they're approaching a stall. ie. No stall buffet felt because of lack of feel, and faith in the system that'll 'save the day'. My question is, is there a stall warning fitted to the aircraft? ie. A warning tone like on the light aircraft.
