How does air traffic control work in the US?

In the United States, air traffic control is managed by the Federal Aviation Administration (FAA). The FAA is responsible for ensuring the safe and efficient movement of air traffic throughout the national airspace system. Air traffic control involves the use of ground-based radar systems, communication equipment, and computer technology to monitor and direct the movement of aircraft.

When a plane takes off, it is guided by air traffic controllers who direct its movement along a specific route, ensure it stays a safe distance from other aircraft, and coordinate with other controllers along the route. The FAA also uses advanced technologies such as Automatic Dependent Surveillance-Broadcast (ADS-B) and the Next Generation Air Transportation System (NextGen) to enhance air traffic control capabilities.
