FAA AMT (Aviation Maintenance Technician) Airframe Practice Exam

When an aircraft's autopilot system corrects an error in the aircraft's attitude and then returns the control surfaces to streamline once the correct position is reached, this is considered normal operation. The autopilot system is designed to make adjustments to the aircraft's attitude to maintain a desired flight path and level of stability. Once the desired position is achieved, the control surfaces are returned to their streamlined position to minimize drag and ensure smoother flight. This is a standard function of the autopilot system and indicates that it is working as intended.

Option A: System malfunction - This option is incorrect because returning the control surfaces to streamline after correcting an error is not indicative of a system malfunction, but rather a normal operation of the autopilot system.

Option C: Emergency mode activation - This option is incorrect because the described scenario does not involve the activation of an emergency mode. It simply describes the autopilot system making adjustments to correct an error and then returning the control surfaces to streamline upon reaching the correct position.

Option D: Flight path deviation - This option is incorrect because the scenario described does not involve a flight path deviation. The autopilot system is adjusting the aircraft's attitude to maintain the desired flight path, and once the correct position is reached, the control surfaces are returned to streamline, indicating normal operation.
