A contract air traffic controller performs the same responsibilities and duties as a regular full-time air traffic controller but on a temporary basis. As a contract air traffic controller, your duties include monitoring flight traffic, communicating with the pilot, ensuring that the airspace around the airport is properly monitored so that planes can safely take off and land, and maintaining a proper schedule of planes. You work on assignment or for an independent contracting company that sends you to control towers that have a shortage of full-time controllers.
