The Federal Aviation Administration (FAA) is a federal agency of the United States, operating as a major component of the U.S. Department of Transportation (DOT). It was established by the Federal Aviation Act of 1958 to consolidate various aviation safety and regulation duties into one centralized body. Unlike state agencies, which only have jurisdiction within their specific borders, the FAA has absolute authority over all civil aviation throughout the entire United States and its international waters. Its mandates include the regulation of commercial space transportation, the certification of aircraft and pilots, and the operation of the nation’s air traffic control system. While individual states may have their own departments of transportation that handle local airport funding or small-scale regional planning, they must all adhere to the safety standards and airspace regulations set by the FAA. In 2026, the FAA continues to be the lead authority on integrating new technologies like delivery drones and electric vertical takeoff and landing (eVTOL) vehicles into the national airspace.
