An effective forward step in terminal area air traffic control has been accomplished by development and installation of Radar Approach Control (RAPCON) Center and control tower prototype facilities described. Esoteric complexes detailed provide airport and approach controllers with radar and communication implementation of manual aids to jet and propeller driven traffic control procedures and techniques. Equipment reported also serves as manual backup and override facilities capable of eventual expansion to fully automatic air traffic control system operation dictated by high-speed jet performance characteristics.
