What does manual reversion enable in a hydraulics failure?

• A. Automatic stabilization.
• B. The pilot to control the aircraft using a system of wire cables and pulleys.
• C. Standby hydraulics take over.
• D. Electronic autopilot.

Answer: (B)

Manual reversion provides a direct mechanical path from the cockpit controls to the control surfaces, so the pilot can still move the surfaces even if the hydraulic system fails. This is achieved through a system of wire cables and pulleys that connect the flight controls to the ailerons, elevators, and rudder, bypassing hydraulic actuators. That’s why describing control of the aircraft via cables and pulleys best captures the essence of manual reversion. Other options rely on automatic systems, standby hydraulics, or autopilot, none of which restore direct mechanical control when hydraulics are lost.
