A320 control surface failure
Interesting question came up today. What would happen if a single control surface failed? Say a single aileron or elevator failed in the neutral position.
What control law would be active?
How would the handling change? Would the other surfaces move to compensate for the loss so that the feel is the same?
How do other FBW planes deal with this failure?
I couldn't find answers to these specific questions in our manuals.
Thanks as always

PRO- ABN-F_CTL: Active Control Law Table shows:
with 1 aileron failed - you still remain in Normal Law.
If an Elevator servo is jammed - then Normal Law.
If 1 Elevator is jammed then in Pitch you get ALTN Law with reduced protection, Roll Direct and ALTN Law in Yaw

Boeing 777, 787, 777X will stay in Normal Mode with any one surface jammed. Very initial response to pilot input may not be as sharp due to reduced control power with a surface jammed, but pitch axis on 777 and all axes on 787 and 777X involve integral control in Normal Mode that will use the remaining surfaces to achieve commanded steady maneuver.

I'll have to try to source it somehow.
If yours has been removed, then pm me and I'll send you screen shots of the relevant pages.
