===Wing twist===

{{main|Aeroelasticity}}

Another version of the problem occurs when the amount of airflow over the [[wing]] becomes greatso enoughgreat that the force generated by the [[aileron]]s is enough to twist the wing itself, due to insufficient [[Torsion (mechanics)|torsional]] stiffness of the wing structure. For instance when the aileron is deflected upwards in order to make that wing move down, the wing twists in the opposite direction. The net result is that the airflow is directed down instead of up and the wing moves upward, opposite of what was expected. This form of control reversal is often lumped in with a number of "high speed" effects as [[compressibility]].
