What is stability augmentation and which systems provide it?

• A. Systems that help maintain stable flight, such as autopilots and flight-control laws; reduce pilot workload and improve handling.
• B. Systems that increase instability to improve maneuverability.
• C. Only mechanical adjustments made by the pilot.
• D. Systems that display flight data.

Answer: (A)

Stability augmentation refers to automatic control systems that dampen the aircraft’s motion and help keep it stable, reducing how much the pilot must work to maintain steady flight. These systems sense the aircraft’s attitude and motion and automatically adjust control surfaces to oppose disturbances like gusts or abrupt inputs, smoothing the response and improving handling. Systems that provide this include autopilots, which can automatically hold altitude, heading, or attitude, and flight-control laws (the built-in control logic in the aircraft’s fly-by-wire or servo-controlled systems) that shape how control surfaces respond to pilot input and disturbances. Trim systems and gust alleviation features are often part of this augmentation too, all working together to keep the aircraft stable with less pilot effort. So the best description is that stability augmentation consists of systems that help maintain stable flight, reduce pilot workload, and improve handling, such as autopilots and flight-control laws. It’s not about increasing instability, not merely mechanical adjustments made by the pilot, and not just displaying flight data.
