An airport is a location where aircraft such as aeroplanes, helicopters, and blimps take off and land. Aircraft may also be stored or maintained at an airport. An airport consists of at least one surface such as a runway, a helipad, or water for takeoffs and landings, and often includes buildings such as hangars and terminal buildings. Larger airports may have fixed base operator services, seaplane docks and ramps, air traffic control, passenger facilities such as restaurants and lounges, and emergency services. A military airport is known as an airbase or air station. The terms airfield, airstrip, and aerodrome may also be used to refer to airports, and the terms heliport, seaplane base, and STOL port refer to airports dedicated exclusively to helicopters, seaplanes, or short takeoff and landing aircraft.In some jurisdictions, the term airport is used where the facility is licensed as such by the relevant government organisation (e.g. Federal Aviation Administration (FAA), Transport Canada).
