The invention discloses a heeling-angle-availability-based optimal planning method of a reentry corridor. The method comprises the following steps: firstly determining an initial reentry angle value range, determining a heeling angle area and selecting a heeling angle section; then selecting a longitudinal flight range zone and a horizontal flight range zone of an aircraft and dividing an initial reentry angle input zone; calculating longitudinal flight range deviation and horizontal flight range deviation of the aircraft when arriving at each terminal, finishing checking all the initial reentry angle input zones and all terminal zones and determining an initial reentry corridor; and finally increasing combined perturbation deviation, updating the reentry corridor and obtaining a mobility evaluation result; controlling an aircraft orbit by taking a minimum reentry angle in the evaluation result as an orbit controlling and aiming reentry angle. According to the method, the reentry corridor is designed, so the problems that the terminal state is inaccessible and the aiming point is not optimal due to a convention method of a jumping reentry aircraft can be solved; the design pressure of the reentry guidance law is relieved; the quick evaluation result can be shown to ensure that the task design is reliable and accurate.
