How do yaw damper and stability augmentation systems improve handling?

• A. They automatically adjust surfaces to dampen sideslip and reduce pilot workload.
• B. They adjust engine thrust to compensate sideslip.
• C. They dampen gust effects on elevator.
• D. They function only during takeoff.

Answer: (C)

Automatic stabilization systems sense yaw and roll motion and automatically command small control-surface movements to oppose destabilizing motions, keeping the aircraft stable and reducing pilot workload. A yaw damper uses the rudder to damp yaw and suppress side-to-side oscillations like Dutch roll, helping the aircraft remain coordinated without the pilot having to babysit the rudder. Stability augmentation systems broaden this by applying coordinated corrections via actuators on the control surfaces (often rudder and ailerons) to maintain stability in flight, making handling smoother and less demanding for the pilot. These systems operate continuously across flight phases, and they don’t adjust engine thrust or target gusts on the elevator specifically.
