The behavior of an aircraft while airborne. An aircraft, while in the air, is free to move in six degrees of freedom (Fig. 1). The aircraft can translate along any of its three axes, X, Y, and Z. The corresponding translational velocities are identified as U (forward velocity), V (side velocity), and W (up or down velocity), respectively. In addition, the aircraft can rotate about any of its three axes, X, Y, and Z. The corresponding rotational velocities are labeled as P (roll rate), Q (pitch rate), and R (yaw rate) respectively.
