Automated En Route Air Traffic Control Algorithmic Specifications. Volume 1. Trajectory Estimation

Abstract : This Algorithmic Specification establishes the design criteria for four advanced automation software functions to be included in the initial software package of the Advanced Automation System (AAS). The need for each function is discussed within the context of the existing National Airspace System (NAS). A top-down definition of each function is provided with descriptions on increasingly more detailed levels. The final, most detailed description of each function identifies the data flows and transformations taking place within each function. This document consists of five volumes. Volume 1, Trajectory Estimation, contains a functional design for deriving a predicted four-dimensional (space and time) path, or trajectory, for each participating aircraft.
