Refer to figure.
Approaching a certain angle of attack, called the αMAX on the Airbus aircraft, the high angle of attack protection will inhibit pilot’s pitch up inputs even if they keep pulling the stick fully back. In this condition, the pilot can still make gentle turns if required. When the stick is released, the angle of attack returns to the αPROT and stays there. In the same way, the nose-up trim will also be inhibited.
