My new lesson

The control reversal:

Is an advers effect on the controllability of aircraft when the flight controls reverse themselves  in a way that is not intuitive.
This problem occurs at high speeds when the airflow over the wing becomes so great that the force generated by the ailerons is enough to twist the wing. For example the aileron is deflected up for make the wing move down, the wing twists in the opposite direction, the airflow goes directed down it and the wing moves upward.
