The conclusions of a major technology assessment effort are discussed, and it is noted that the Upgraded Third Generation System (UG3RD) and extensions to it can handle air traffic control requirements to the end of the century. The UG3RD is now transformed into a broad based system design which is highlighted by 9 key features. The system will provide a ground based separation service, the Intermittent Positive Control (IPC), which will maintain surveillance on all aircraft and will transmit advisory collision avoidance instructions. UG3RD will incorporate a method of addressing or selectively interrogating discrete aircraft by the Discrete Address Beacon System. Integration and utilization of the area navigation (RNAV) in 2-, 3-, and 4-dimensional versions is a goal of the UG3RD. A new Microwave Landing System (MLS) is now under development, and an attempt will be made to achieve higher levels of automation in monitoring potential problems in metering of arriving aircraft etc. Airport surface traffic control, the wake vortex avoidance system, an automated flight service station, and aeronautical satellites for trans-ocean flights are other highlights discussed here.
