[[File:Flight dynamics with text.png|thumb|right|Rotation around the three axes|alt="pitch" is a nose-up/nose-down rotation, "roll" is a rotation lifting one wing and lowering the other, "yaw" rotation moves the nose in a left/right direction]]

An aircraft is free to rotate around three axes that are perpendicular to each other and intersect at its [[center of gravity]] (CG). To control position and direction a pilot must be able to control rotation about each of them.
