Even at small airports, air traffic controllers must maintain a constant awarenessEven at small airports, air traffic controllers must maintain a constant awareness

this project is to create a model-based program which air traffic controllers at smallthis project is to create a model-based program which air traffic controllers at small

airports may use to track aircraft positions and to issue orders to the pilot accordingly,airports may use to track aircraft positions and to issue orders to the pilot accordingly,
