Which component is specifically powered by hydraulic System A?

• A. Normal brakes
• B. Yaw damper
• C. Alternate brakes
• D. Landing gear

Answer: (C)

The correct choice identifies the component that is specifically powered by hydraulic System A. Hydraulic systems in aviation are designed to provide necessary pressure to various critical components, and in this case, alternate brakes are specifically associated with hydraulic System A.

Alternate brakes serve as a backup for normal brakes, which are typically powered by a different hydraulic system or source. In instances where the primary braking system fails or is compromised, the alternate brakes take over the function, ensuring the aircraft can still come to a safe stop.

Hydraulic System A is responsible for powering these alternate brakes, meaning that in any situation where the alternate brakes are engaged, they rely solely on this specific hydraulic system to operate effectively. This underscores the importance of understanding the different hydraulic systems and the components they control, as it directly relates to aircraft safety and operational functionality.

Therefore, the identification of alternate brakes as the component powered by System A aligns with the design and safety protocols in hydraulic systems used in aviation.
