Abstract: A computerized system is provided for automated aircraft traffic control. The system includes a master control unit having stored information identifying and characterizing all aircraft flying in the controlled airspace. A plurality of regional control units are linked for communication with the master control unit. Airport terminal and enroute control stations in each region are linked to the regional control unit for that region. Each aircraft flying in the region is equipped with a data-link console for communication with the regional control unit. The aircraft data-link provides identification and flight condition data to the regional control unit, and the regional control unit provides weather data and guidance signals to the aircraft. The guidance signals guide each aircraft along flight paths formed by a plurality of airway grids disposed at fixed angles with respect to each other and at each of a plurality of flight levels.
