How do stability and control differ?

• A. Stability is the tendency to resist changes in flight state; control is the active act of changing state using surfaces and systems.
• B. Stability is the active adjustment of flight state; control is passive stabilization.
• C. Stability relates to color of the aircraft; control relates to weight distribution.
• D. Stability determines engine power; control determines payload.

Answer: (A)

Stability is the aircraft’s inherent tendency to resist changes in its flight state and to return to a steady condition after a disturbance. It’s a passive property of the airplane’s aerodynamics, weight distribution, and configuration. Static stability describes the initial tendency to return or continue away after a small gust, while dynamic stability describes how quickly and smoothly the motion settles back to equilibrium. Control is the active ability to change the flight state using inputs and actuators—surfaces and systems that create moments to alter attitude or path. Through the elevator, ailerons, rudder, throttle, spoilers, or other controls, the pilot (or autopilot) can command the airplane to pitch, roll, yaw, or change speed and direction. So, stability provides predictable, self-correcting behavior after disturbances, while control provides the means to intentionally steer and maneuver the aircraft. An aircraft should be both reasonably stable and have sufficient control authority to be safely and precisely piloted.
