The SEMAs provide the actuator input for which system to dampen disturbances?

• A. Autopilot
• B. SAS
• C. Flight Control System
• D. Yaw Controller

Answer: (B)

Damping disturbances relies on a fast feedback loop where sensors detect a deviation and actuators apply immediate corrective forces to keep the aircraft stable. The Stabilization Augmentation System is the part of the control architecture that uses those actuator inputs to generate quick surface movements that counter gusts and vibrations.

The SEMAs feed the actuator input to the Stabilization Augmentation System, making SAS the mechanism responsible for dampening disturbances. Autopilot handles broader flight-path commands, not the fine, real-time disturbance rejection, and the yaw controller focuses on yaw movement rather than overall stabilization. The full flight control system includes more than just disturbance damping, but the SAS is the primary path for damping through actuator inputs from the SEMAs.
