I think this is a fly by wire question. Simply described as follows:

The Airbus FBW aircraft have four levels of redundancy. Firstly, Normal Law is all computers working, with all systems and protections normal. Lose a couple of computers, then you're in Alternate Law where everything works, but you lose some protections. Lose a bit more, then you go to Direct Law where the control movement is proportional to stick movement. In otherwords, it's now a Boeing! (Taking cover at this point ). If it's really not your day and you've lost all the computers tou are now in maunual backup and the rudders control yaw (and consequently roll) and the stab trim contols pitch. Sounds drastic, but still flyable.
