ABSTRACT	The return flight path of the space shuttle used to be designed through parametric iteration to reduce the gaps at the interface points of the two adjacent flight paths, of different flight phases of reentry, TAEM (Terminal Area Energy Management) and AL (Approach Landing), which are maneuvered by the guidance program. This research shows that the return flight path can be deduced from the gliding performance which is determined by the lift/drag ratio (L/D), where L/D is controlled by the angle of attack, the speed brake angle and the bank angle, and that an algorithm to determine the return flight path corridor depending on the gliding capability of the vehicle can be derived.
