Communication in Air-Traffic Control

One of the major obstacles to the solution of the air-traffic control problem is the limitation imposed on information flow by the outdated air-to-ground communication system now in use. A study of the present system and its deficiencies gives a set of requirements for a communication system that will assist materially in the solution of the air-traffic control problem. Another set of communication system requirements is obtained by analysis of the characteristics of the future air-traffic-control system. The composite of these two classes of requirements can be satisfied to a large extent by many communication techniques presently available. The problem of determining an optimum air-trafficcontrol communication system is now in the process of being solved. This system will be called the Air-Traffic-Control Signaling System.
