Which motion is about the aircraft's lateral axis and is controlled by the elevators?

• A. Yaw
• B. Pitch
• C. Roll
• D. Bank

Answer: (B)

Pitch is the rotation about the lateral axis, which runs wingtip to wingtip. This motion makes the nose move up or down. Elevators on the horizontal stabilizer are the control surface that governs pitch by changing the tail’s lift and producing a pitching moment about the aircraft’s center of gravity. Deflecting the elevator upward raises the nose; deflecting it downward lowers the nose. Yaw is rotation about the vertical axis (rudder controls it), roll is rotation about the longitudinal axis (ailerons control it), and bank is the tilt that results from rolling.
