A simple guidance scheme is proposed which approximately optimizes the range of the glide phase of a boost‐glide vehicle's trajectory. The scheme requires only altitude, flight‐path angle, and attitude measurements for implementation. The guidance law provides an attitude command based on the actual flight‐path angle and on a calculated flight‐path angle associated with that of an equilibrium, constant‐dynamic‐pressure, glide of maximum lift‐to‐drag ratio. By proper weighting of these two inputs, an approximately optimal guidance control is realized. Two examples are given which demonstrate the trajectory characteristics for a high‐performance aircraft and for a missile‐type vehicle.
