Abstract

A site-selectable air traffic control system and method for interacting with a user, the system and method generating a representation of at least one moving aircraft having an initial position and heading with respect to a selected site for producing a dynamic simulation of an air traffic scenario. The site selected may consist of one of a plurality of stored sites or a modification of one of those sites. Controller commands issued by a user are entered for altering the air traffic scenario. Rules and procedures stored in a general knowledge base and a site-specific knowledge base are compared to the present state of the simulation of the air traffic scenario or to the controller command by an expert system for issuing a warning upon the immediate or foreseeable failure to observe any rule or procedure in the knowledge bases.
