Keywords: re-entry vehicle, footprint, bank angle, trajectory

Footprint is defined as a set of all reachable landing locations. In this paper footprint is separated into inner and outer boundaries which are generated based on different methods. It involves algorithms for solving maximum downrange, maximum crossrange, and minimum trajectory problems. Simulation is given and verifies the proposed approach.
