On any given day, more than 85,000 flights are in the skies in the United States. Only one-third of those operations are commercial carriers. The remaining two-thirds include general aviation, with private planes and business jets, air taxi flights, military flights and air cargo flights. This translates into roughly 5,000 planes in the skies above the United States at any given moment. More than 15,000 federal air traffic controllers in airport traffic control towers (ATCT), terminal radar approach control (TRACON) facilities and air route traffic control centers (ARTCC) guide pilots through the system. These controllers provide air navigation services to aircraft in domestic airspace and 24.6 million square miles of international oceanic airspace delegated to the United States by the International Civil Aviation Organization (ICAO). The FAA’s mission is to provide the safest, most efficient aerospace system in the world, and NextGen is the FAA’s comprehensive overhaul of the National Aviation System (NAS) to make air travel more convenient and dependable.

All results are reported by Fiscal Year (FY), October 1 — September 30, or Calendar Year (CY).

High Low

A global Air Traffic Management (ATM) system should provide an operating environment that ensures all airspace users have right of access to the resources needed to meet their specific operational requirements and that the shared use of airspace by different users can be achieved safely.
