- The main purpose of air traffic control is to keep safe distances between planes in air and on ground, minimize delays and inform pilots of weather changes.
- Traffic in the air is controlled from a tower and can be classified into three general functional groups: ground control, local or air control and clearance delivery (which coordinates taxiing).
- The task of controlling air traffic is performed by the Federal Aviation Administration who provides service through most U.S. airspace.
- The job of an air traffic controller is notoriously stressful but controllers receive high pay and excellent benefits. The average annual salary for an air traffic controller in May 2007 was $112,930.
- The safety of all air travel relies heavily on the effectiveness and accuracy of the air traffic control system and the controllers on duty.
