An Overview of a Trajectory-Based Solution for En Route and Terminal Area Self-Spacing: Fourth Revision

This paper presents an overview of the fourth revision to an algorithm specifically designed to support National Aeronautics and Space Administration's (NASA's) Airborne Precision Spacing concept. This algorithm is referred to as the Airborne Spacing for Terminal Arrival Routes version 11 (ASTAR11). This airborne self-spacing concept is trajectory-based, allowing for spacing operations prior to the aircraft being on a common path. Because this algorithm is trajectory-based, it also has the inherent ability to support required-time-of-arrival (RTA) operations. This algorithm was also designed specifically to support a standalone, non-integrated implementation in the spacing aircraft. Revisions to this algorithm were based on a change to the expected operational environment.
