Yaw is rotation about which axis?

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

Answer: (A)

Yaw is rotation about the vertical axis, the line running top to bottom through the aircraft. Turning the nose left or right without tipping the aircraft up or down is yaw. The lateral axis runs wing to wing, and rotation about it is pitch (nose up or down). The longitudinal axis runs nose to tail, and rotation about it is roll (wings tilt). The normal axis isn’t used for describing these primary rotations in this context.
