Abstract : The purpose of the Phase I study was to determine new techniques that might be employed to improve air/ground communications in the automated NAS environment. Areas studied relate to spectrum utilization, channel loading, pilot and controller workloads, air fleet growth, air/ground message requirements, and system operational techniques such as discrete aircraft frequency and frequency pooling concepts. Mathematical models of the present and future systems were constructed, and computer programs written to simulate system operation. Many concepts and philosophies were considered with the result that the discrete aircraft frequency concept appeared most feasible and most likely to satisfy the parameters required of an improved air/ground communication system. The discrete frequency system is proposed for implementation in Phase II. This system differs from the present discrete controller frequency system in that a single frequency would be assigned an aircraft for the duration of a flight. The ground system would semiautomatically change to the aircraft's frequency when communication was desired as the flight progresses, as opposed to the aircraft changing frequency at every sector boundary. This document is divided into three books. Book I contains the executive summary. (Author)
