Which rotational axis corresponds to yaw in UAV orientation?

Which rotational axis corresponds to yaw in UAV orientation?

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

Answer: (D)

Yaw is the rotation about the vertical axis, which runs top to bottom through the aircraft. Rotating around that axis changes the direction the nose points, i.e., the heading, without inherently tilting the aircraft up or down or rolling it. In contrast, pitch is the rotation about the lateral axis (through the wings) that tilts the nose up or down, and roll is about the longitudinal axis (nose to tail) that tilts the wings. Elevation isn’t a rotational axis; it refers to height above the ground, not a rotation. So, yaw corresponds to rotation about the vertical axis, which changes heading.
