Which term refers to an aircraft's capability to respond to pilot control, especially with regard to flight path and attitude?

• A. Maneuverability
• B. Controllability
• C. Stability
• D. Responsiveness

Answer: (B)

Controllability describes an aircraft's ability to respond to pilot control and to follow the intended flight path and attitude. It reflects how effectively control inputs translate into the aerodynamic moments that steer the aircraft, so small stick or pedal movements produce predictable, timely changes in pitch, roll, and yaw. This is different from stability, which is about the aircraft’s tendency to resist disturbances and return to a trim condition without input. An aircraft can be very stable yet hard to maneuver if its controllability is poor. Maneuverability covers the overall ability to change direction or attitude quickly, including performance factors like power and speed, and is a broader concept than just the control response. Responsiveness relates to how quickly the aircraft reacts to control inputs, but the formal term for the control-effectiveness aspect is controllability. So the term that best matches the idea of responding to pilot control to shape flight path and attitude is controllability.
