Name three systems inhibited when the control lock is engaged.

Name three systems inhibited when the control lock is engaged.

• A. Pusher, Throttles above a certain level, Auto pilot
• B. Pusher, Landing gear, Auto pilot
• C. Throttles, Rudder, Elevators
• D. Auto pilot, Flaps, Spoilers

Answer: (A)

When the control lock is engaged, it secures the flight-control pathways so automatic movements can’t occur, usually on the ground or during maintenance. This prevents inadvertent or conflicting commands from driving the aircraft. In particular, the lock disables the actuator path known as the pusher, prevents automatic thrust management from taking over once the throttle is advanced beyond a set level, and shuts down the autopilot. So, the systems affected are the pusher actuators, the autothrottle function (above a certain throttle position), and the autopilot. This keeps the airplane under manual control and avoids unintended control inputs while the lock is active.
