This paper reports the recommendations of the Air Traffic Control Advisory Committee for improving air traffic control into the 1990s. The recommended program has three objectives: increase airport capacity to satisfy the demand in the 1975-1980 period and beyond, provide en route and terminal airspace capacity adequate for the traffic of the 1980s, and determine the ingredients of a fourth generation air traffic control system for the post 1990 period. Details of the steps necessary to achieve these objectives are supplied, along with cost and duration estimates.
