Which axis passes vertically through the center of gravity?

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

Answer: (A)

The vertical axis is the line that runs top to bottom through the center of gravity, defining yaw motion. In flight dynamics, yaw is the rotation about this axis, which changes the aircraft’s heading without pitching or rolling. The longitudinal axis runs nose to tail and is linked to roll, while the lateral axis runs wing to wing and is linked to pitch. The term normal axis isn’t part of the standard body-axis set used here, so it isn’t the axis described.
