The Federal Aviation Administration (FAA) is the national authority in the United States responsible for the safety of civil aviation. Its primary duties include regulating all aspects of civil aviation, which includes issuing Airworthiness Directives (ADs) to fix safety issues in aircraft, licensing pilots and flight engineers, and certifying new aircraft designs. The FAA also manages the National Airspace System, operating the complex Air Traffic Control (ATC) network that keeps planes separated in the sky. Beyond safety, the FAA is involved in noise control, environmental research, and the regulation of commercial space transportation (launching and re-entering rockets). In 2026, the FAA is heavily focused on the integration of "NextGen" technology, which uses GPS-based systems to make flight paths more efficient, and the developing regulations for unmanned aircraft (drones) and Urban Air Mobility (flying taxis) in metropolitan areas.
