yaw

Yaw refers to a side-to-side motion or rotation around a vertical axis. In ships, yawing is an erratic deviation from a course, often caused by heavy seas. For airplanes, yaw is a rotation that causes the nose to move opposite to the direction of a horizontal turn. This motion is controlled by the rudder, which counteracts "adverse yaw" – a phenomenon where the raised wing in a turn creates drag that pulls the nose away from the turn's direction. The term "yaw" originated in sailing and was later adopted in aeronautics to describe aircraft movements, alongside "pitch" and "roll".12345
