Which option best defines controllability?

• A. Trim effect
• B. Inertial response
• C. Controllability
• D. Stability

Answer: (C)

Controllability is about how effectively the aircraft responds to the pilot’s control inputs, allowing you to influence its attitude and flight path in a predictable, timely way. In a glider, good controllability means small, nimbly applied inputs lead to coordinated changes in roll, pitch, and yaw, enabling you to enter turns, adjust airspeed, and guide the glider where you want it to go. Trim is a separate idea: it’s adjusting the control to hold a steady flight with minimal force. Inertial response refers to the delay caused by the aircraft’s mass resisting rapid changes, and stability is the tendency to stay in or return to a particular state after a disturbance. Controllability specifically focuses on how well you can effect deliberate, controlled changes using the controls.
