Does the airbus allow you to roll into a 45 or maybe a 70 degree bank? I have heard (having never flown one) that the computer limits what it sees as acceptable limits. My personal opinion is that if I as a captain, decide I need a 70 degree bank to avoid something I don't want to have to negotiate with a computer, particularly a french computer. Of course I see the logic of protecting the aircraft from idiots as well - and we all know there are some out there.
