The year for shaping a digital operations R&D program

Abstract

Digital systems which deal with functions outside the aircraft in commercial aviation are discussed with attention to navigation and communication. New systems of air traffic control (ATC) are described, including time division multiple access (TDMA) to ground-based ATC units and to the Navstar/GPS (global positioning system). Such innovations are expected to come on-line before the mid-1980s, and greatly increase air safety, while at the same time making a pilot's work easier.
