The VMS has the only large six-axis motion system in the world with independent control of rotations and translations, known as degrees of freedom. The ICAB, with a pilot inside, can be maneuvered in any of the six ways that an aircraft moves, including three translational degrees of freedom (vertical, lateral, and longitudinal) and three rotational degrees of freedom (pitch, roll, and yaw). The pictures below illustrate these six degrees of freedom in aircraft motion.
