A constrained flight route monitor system in terminal control area for air traffic control

A flight route monitor for terminal control area (TCA) application in air traffic control (ATC) including constraints is presented. To increase flight security, some restricted areas in the TCA are specified to limit flight activities in terms of simple equations. The aircrafts are monitored with those created constrained boundaries. ATC controllers will be alerted to any constraint violation. The constrained flight route monitor assists the ATC controller for additional functions. A knowledge-based system is introduced to handle all routine procedures in ATC. This system is implemented into PC-AT using Turbo-Prolog. It demonstrates some useful functions for ATC automation. A prototype expert system has been implemented and demonstrated for TCA operation using the example of the Hua-Lien TCA in the Taipei Flight Information Region
