The study examines the usefulness of a direct numerical optimization technique for developing real-time algorithms to plan optimized four-dimensional arrival flights. This time-based guidance algorithm is intended to serve as a fundamental building block in a ground-based processor for the coordinated planning of air traffic movements in an extended terminal area. Based on knowledge of the capabilities of the aircraft, the actual atmospheric conditions and a set of time-constraints in the form of a four-dimensional 'tube' within which the aircraft has to stay, fuel-optimal trajectories are computed that are nominally free of conflicts over a specified time interval (typically 25 minutes).
