This paper describes the major features of the Upgraded Third Generation System (UTGS) for air traffic control. The three major goals of this improved system are performance improvements to handle a nearly doubling of air traffic, maintenance or improvement of safety, and the accomplishment of the first two goals in a way that constrains or reduces the costs, including capital costs, maintenance and operating costs and user costs. Guiding considerations in the present development of the UTGS are: protection of the environment: minimization of air pollution and noise; conservation of energy; maintenance of maximum freedom of flight for each user without compromising the safety of the other users of the air space; and rectifying the present situation whereby airline companies are paying the bulk of operating costs and general aviation is paying a much lower share. Several features of the UTGS which are described include the Discrete Address Beacon System (DABS), the Microwave Landing System (MLS) and the Automated Radar Terminal System (ARTS) III. In conclusion it is pointed out that the UTGS by increasing airside capacity will necessitate engineering and development projects to improve to improve landside capacity in such a way as to match the increased airside capacity.
