Mach 4.0, I might be a bit late to answer, but you could have avoided much turmoil if you had asked more neutral, i.e. FBW instead of A320. We all know that A320 isn't the only FBW model nowadays and your questions sounds like another French-bashing. An A320 will have the same problem like a Boeing 777 or 787 or an Embraer 170 or Saab 2000 or any other FBW aircraft.
Ask the right question - and you will get the right answer!
Happy continuation of the discussion (I agree that all modern airliners will fall from the sky in case of a nuclear holocaust).
