During stall recovery training, fighting the urge to use the aileron to overcome a sudden wing drop can take forethought and even sheer will power on the part of the student pilot. In a true stall emergency, which can take us completely by surprise, picking up a dropping wing with the aileron can be an instinctual, but also a very dangerous, reaction.
Most light airplanes are designed with wings that stall progressively outward from the wing roots to the wingtips. This provides a measure of aileron control even in a stall as the wingtips continue to provide some degree of lift and the ailerons still have some control effect.
