Which system includes a Standby Yaw Damper?

• A. Standby hydraulic system.
• B. A hydraulic system.
• C. B hydraulic system.
• D. Nose wheel steering system.

Answer: (A)

The key idea is redundancy for flight stability. A yaw damper helps keep the aircraft from yawing excessively or dutching into unstable oscillations by automatically adjusting the rudder based on rate sensing. When primary hydraulics fail, you still want reliable yaw damping, which is exactly what the standby hydraulic system provides. It powers the standby yaw damper so the aircraft remains stable even with main systems lost. The nose wheel steering system handles ground steering and isn’t responsible for in-flight yaw damping. The A and B hydraulic systems are the primary power sources for most actuators, but the standby yaw damper is specifically tied to the standby hydraulic system to ensure it remains available in a failure scenario.
