Which axis runs from wing tip to wing tip and governs pitch (nose up or down)?

Which axis runs from wing tip to wing tip and governs pitch (nose up or down)?

• A. Lateral Axis
• B. Longitudinal Axis
• C. Vertical Axis
• D. Diagonal Axis

Answer: (A)

Pitch is rotation about the axis that runs from wingtip to wingtip—the lateral axis. This axis stretches across the wings, and when the airplane pitches, the nose moves up or down as the aircraft tilts about that wing-to-wing line. Pulling back on the controls raises the nose because the wings rotate around this lateral axis, while pushing forward lowers the nose. For context, rolling left or right occurs about the longitudinal axis (nose to tail), and yawing left or right occurs about the vertical axis (top to bottom). The diagonal axis isn’t used in this standard three-axis framework.
