Stability in an aircraft is defined as which of the following?

• A. The ability to quickly change attitude
• B. The tendency to return to or maintain a steady flight condition after a disturbance
• C. The maximum speed during flight
• D. The color of the aircraft

Answer: (B)

Stability is about how the aircraft behaves after a disturbance. A stable airplane tends to return to or maintain a steady flight condition after being nudged by a gust or control input. This includes static stability—the initial tendency to move back toward equilibrium—and dynamic stability—how the motion settles out over time. For example, if a gust pushes the nose up, a stable airplane will create a nose-down moment that brings it back to the trimmed attitude, ideally with any oscillations dying out. The ability to quickly change attitude describes controllability or maneuverability, not stability. Maximum speed and color are unrelated to how the aircraft responds to disturbances.
