Air Traffic Control
MIT OpenCourseWare offers this course on the systems that keep aircraft moving safely through controlled airspace. Lectures cover the systems-analysis approach to capacity and safety problems, surveillance technology including the National Airspace System and Automated Terminal Radar Systems, navigation subsystems, aircraft guidance and control, communications, and collision avoidance systems. The course also examines sequencing and spacing procedures used in terminal areas and closes with a critical look at past proposals for the system alongside likely future problem areas. Materials include MIT's lecture notes and course readings, free to access online under an open license, with no certificate offered. The course suits students in aeronautics and astronautics who want a systems-engineering view of how air traffic is actually managed, rather than a pilot's-eye introduction to aviation.
