The body axis system, denoted by a subscript b b, originates at the aircraft center of gravity. The positive direction of the xb x b -axis is towards the front. The positive direction of the yb y b -axis is towards the right wing tip, and the positive direction of the zb z b -axis is towards the bottom of the aircraft.
