Issues in Air Traffic Control

Professor Walter M. Hollister

Department of Aeronautics and Astronautics

Massachusetts Institute of Technology


As the Air Traffic Control system moves toward an environment of free flight, restrictions will be placed on the free movement of aircraft only to preserve safe separation. It is important to understand the frequency and severity of the situations which will require these restrictions in order that the separation assurance system can function effectively. A mathematical model will be described which clearly establishes fundamental relationships between traffic densities, flow structure, and alarm rates experienced by aircraft. Radar tracks recorded at MIT Lincoln Laboratory are used to determine patterns of the current traffic. It is concluded that alert rates can be dramatically reduced by using intent-based maneuver constraints in the detection process.
