A320 MQF List – Airplane General Practice Test

Automatic pitch trim is inhibited when angle of attack protection is active to ensure the safety and controllability of the aircraft. During critical flight conditions, such as when the aircraft is approaching a stall or in a high angle of attack situation, controlling pitch is paramount. The automatic pitch trim function could interfere with the pilot's need to manage the aircraft's attitude and maintain safe performance.

In this scenario, the control of pitch is directly linked to the stability and safety of the aircraft, as allowing the automatic trim to adjust could make it easier to inadvertently reach a stall. This inhibition helps maintain pilot authority and keeps the aircraft within safe operating limits.

The other options relate to different conditions that do not directly inhibit automatic pitch trim, meaning they do not share the relationship with angle of attack protection as the correct answer does.
