The air traffic control system is a complex web of radars, comput ers, weather detection systems, navigation beacons, control towers, enroute centers and people, tied together through a network of tele communications links. Approximately 550 airports have faa air traffic control towers which control aircraft in the vicinity of airports. Of these airports, 289 use radar to control aircraft on their approaches and depar tures. There are also 21 Air Route Traffic Control Centers or enroute centers which control aircraft at higher altitudes between airports. In addition, there are approximately navigation beacons of different types around the country that transmit radio signals ena bling pilots to determine where they are. There are also 759 air ports equipped with faa instrument landing systems which enable pilots to make precision approaches to runways in less than opti mum weather conditions. The faa also has a wide variety of facili ties and equipment for collecting and making available to pilots weather data, including the Flight Service Station system used by general aviation pilots. This air traffic control system is designed and expected to oper ate constantly around-the-clock with a very high level of reliability.
