The Federal Aviation Administration (FAA), established in 1958 and incorporated into the Department of Transportation in 1967, is the national authority governing U.S. civil aviation. It oversees air traffic control, safety regulations, airport infrastructure, and next-generation navigation technologies. The FAA ensures aviation safety through facility oversight, rulemaking, and extensive workforce training. It is also responsible for certifying aircraft, managing airspace, and administering grant programs for airport improvements.
