Carl,
What type of aircraft?
737 of course
On the L-1011 if an aileron is jammed, bungees installed in the input system will extend or collapse to allow movement of the control wheel and any un-jammed aileron.
The answer was in the context of the elevator. But on the 737 the Capt's control wheel controls the ailerons and the FO's the spoilers. Both control wheels are connected thus actuating both types of flight controls accordingly. If a jam on either side is experienced, the opposite side can break the connection and have some roll control.
