Action of the elevators moves the plane on its

• A. Lateral axis
• B. Vertical axis
• C. Longitudinal axis
• D. Dihedral axis

Answer: (A)

Elevators control the aircraft’s pitch, which is rotation about the lateral axis that runs from wingtip to wingtip. When the elevator surfaces deflect, they create a nose-up or nose-down moment about that axis, changing the aircraft’s attitude in the vertical plane. The longitudinal axis governs roll (controlled by ailerons), and the vertical axis governs yaw (controlled by the rudder). The dihedral concept relates to wing angle for stability, not a rotational axis acted on by the elevator.
