Remote Intelligent Air Traffic Control Systems for Non-Controlled Airports

Glenn Brown, University, My, Robert Iskander
The evaluation showed that use of a rule based system as the basis of an intelligent remote air traffic control system for non-controlled airports is a viable proposition.  ...  For a full operational system, the application of the rules and definition of the aircraft circuit area may need refining; however, the results are certainly encouraging.  ...  This of course gives a wide scope for the form and capabilities that an agent possesses and facilitates the development of complex, distributed and fault tolerant systems.  ...
