A framework model through data flow diagrams to model an air traffic control system

Air Traffic Control (ATC) is a service provided by ground-based controller who directs aircraft on the ground and in the air. A controller's primary task is to keep aircraft at a safe distance from each other horizontally or vertically. Secondary tasks include ensuring orderly and expeditious flow of traffic and providing information to pilots, such as radar traffic advisories, weather advisories, flight following and navigation information. In this paper we first provide brief historic background about ATC systems. Later we design and model an ATC using data flow diagrams (DFD) thus providing a framework for such complex control problem. The complete system after the realization of the model is being implemented using MATLAB for the verification of the proposed framework model.
