![]() The Federal Aviation Administration (FAA) has implemented the National Airspace System Architecture, a modernization of the entire air control system. En route controllers help pilots stay on course, advise them about other aircraft in the sector, and often reroute them around storms.Īir traffic controllers are also stationed at more than one hundred flight service stations, which provide pilots with information about weather and terrain, and at the Air Traffic Control Systems Command Center in Virginia, where they oversee the entire system. Is responsible for a certain air sector and employs between three hundred and seven hundred controllers. Each centerĪir traffic controllers work under great stress, coordinating the aircraft at airports to prevent accidents and minimize delays in taking off and landing. ![]() ![]() Once planes are airborne, their movement is controlled by en route controllers, who work in twenty air-route control centers throughout the country. Ground controllers usually work by sight they use radar only if visibility is poor. Once the planes have landed, ground controllers in the tower direct the pilots to their assigned gates. As planes approach runways, other controllers, who also are watching the planes on radar, monitor the aircraft the last mile, delaying any departures that would interfere with landings. When airports are busy, the controllers may have to fit the planes into the traffic pattern of aircraft waiting to land. As planes approach airports, controllers in the radar room observe the planes and direct the pilots to runways. They give pilots permission to taxi, take off, and land their aircraft. Terminal controllers, also known as tower controllers, work in towers near the runways of major airports.
