Hybrid Control in Air Traac Management Systems

In a new collaborative project involving the we have begun the study of hierarchical, hybrid control systems in the framework of air traac management systems (ATMS). The need for a new ATMS arises from the overcrowding of large urban airports and the need to more eeciently land and take oo larger numbers of aircraft, without building new runways. Technological advances that make a more advanced air traac control system a reality include the availability of relatively inexpensive and fast real time computers both on board the aircraft and in the control tower. The usefulness of these technological advances is currently limited by today's air traac control system, which involves the use of \freeways" in the Terminal RADAR Approach Control (TRACON) region around urban airports. These freeways are set approach patterns to runways which do not allow for the possibility of so-called \free ight" by an aircraft to its destination. Limiting the aircraft trajectories in this manner results in the addition of both planned and unplanned delays to air travel.
