Air Traffic Controllers

Air traffic controllers coordinate the movement of aircraft, including within the vicinity of airports and between altitude sectors and control centers, so that they maintain safe distances.

Duties

Air traffic controllers typically do the following:

• Monitor and direct the movement of aircraft on the ground and in the air
• Control all ground traffic at airport runways and taxiways
• Issue takeoff and landing instructions to pilots
• Transfer control of departing flights to other traffic control centers and accept control of arriving flights
• Inform pilots about weather, runway closures, and other critical information
• Alert airport response staff in the event of an aircraft emergency

Air traffic controllers’ primary concern is safety, but they also must direct aircraft efficiently to minimize delays. They manage the flow of aircraft into and out of the airport airspace, guide pilots during takeoff and landing, and monitor aircraft as they travel through the skies. Air traffic controllers use radio equipment to communicate with pilots. They also use radar, computers, and other visual references to monitor and direct aircraft movement in the skies and on airport grounds.

Controllers usually manage multiple aircraft at the same time. For example, a controller might direct one aircraft on its landing approach while providing another aircraft with weather information.

The following are examples of types of air traffic controllers:

Tower controllers direct the movement of aircraft and other vehicles, such as snowplows, on runways and taxiways. They check flight plans, give pilots clearance for takeoff or landing, and direct the flow of aircraft and ground traffic in their area of responsibility. Most observe from control towers, managing traffic from the airport to a radius of 3 to 30 miles out.

Approach and departure controllers ensure that aircraft traveling within an airport’s airspace maintain minimum separation for safety. These controllers give pilots clearances to enter controlled airspace and hand off control of aircraft to en route controllers. They also inform pilots about weather conditions and other critical notices. Terminal approach and departure controllers work in buildings known as Terminal Radar Approach Control Centers (TRACONs). They assist an aircraft until it reaches the edge of a facility’s airspace, usually about 20 to 50 miles from the airport and up to about 17,000 feet in the air.

En route controllers monitor aircraft that leave an airport’s airspace. They work at en route traffic control centers located throughout the country, which typically are not located at airports. Each center is assigned an airspace based on the geography and air traffic in the area in which it is located. As an aircraft approaches and flies through a center’s airspace, en route controllers guide it along its route. They may adjust the flight path for safety reasons, such as to avoid collision with another aircraft. En route controllers direct aircraft for the bulk of the flight before handing off oversight to terminal approach controllers.

Some air traffic controllers work at the Air Traffic Control Systems Command Center, where they monitor traffic within the entire national airspace. When they identify a bottleneck, they provide instructions to other controllers to help prevent traffic jams. Their objective is to keep traffic levels manageable for the airports and for en route controllers.

Air traffic controllers held about 24,100 jobs in 2024. The largest employers of air traffic controllers were as follows:

Most controllers work for the Federal Aviation Administration (FAA).

Most air traffic controllers work in control towers, approach control facilities, or en route centers. Many tower controllers and approach and departure controllers work near large airports. En route controllers work in secure office buildings across the country, which typically are not located at airports.

Most controllers work in semidark rooms. The aircraft they control appear as points of light moving across their radar screens, and a well-lit room would make it difficult to see the screens properly.

Air traffic controllers must remain focused and react quickly to conditions that change frequently. Being responsible for the safety of aircraft and their passengers may be stressful and exhausting. To prevent burnout, the FAA requires controllers to retire at age 56.

Work Schedules

Most air traffic controllers work full time. The FAA regulates the hours that an air traffic controller may work. Controllers may not work more than 10 straight hours during a shift, which includes required breaks, and must have 9 hours of rest before their next shift.

Major airports may operate control towers on a 24-hour basis. Controllers who work at these facilities may work day, evening, or night shifts that include weekends and holidays. Small airports or those that are less busy may have towers that do not operate around the clock. Controllers at these facilities may have standard work schedules.

There are several paths to becoming an air traffic controller. Candidates typically need an associate’s or a bachelor’s degree from the Air Traffic Collegiate Training Initiative program, several years of progressively responsible work experience, or a combination of education and experience. They also must be a U.S. citizen, submit to medical and background checks, and complete training at Federal Aviation Administration (FAA) academy.

The median annual wage for air traffic controllers was $144,580 in May 2024.

Employment of air traffic controllers is projected to show little or no change from 2024 to 2034.

Despite limited employment growth, about 2,200 openings for air traffic controllers are projected each year, on average, over the decade. Most of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire.
