The Automatic Flight Control System is disengaged under which condition?

• A. When autopilot disengages itself automatically
• B. When disengaged by pilots
• C. When a fault is detected by the system
• D. When landing gear is extended

Answer: (B)

The main idea here is that the autopilot (Automatic Flight Control System) is designed to stay under pilot control and be disengaged by the crew when manual control is desired. In normal operation, the way to end the AFCS control is for the pilots to disengage it themselves—typically using the autopilot disconnect switch or by applying force to the flight controls to override the system. This explicit action puts the aircraft back under manual control whenever the crew chooses.

Other situations, like the system detecting a fault or certain automatic conditions, can cause alerts or an automatic change in behavior, but they are not the standard, intentional method for taking the AFCS offline in routine operations. Likewise, landing gear extension is unrelated to the automatic flight control’s disengagement action.
