Abstract: This document describes an algorithm for the generation of a four dimensional trajectory. Input data for this algorithm are similar to an augmented Standard Terminal Arrival (STAR) with the augmentation in the form of altitude or speed crossing restrictions at waypoints on the route. This version of the algorithm now accommodates routes that are totally in the cruise regime. The algorithm calculates the altitude, speed, along path distance, and along path time for each waypoint. Wind data at ...
