An airpor is a facility where aircraft can take off and land. At the very minimum, an airport consists of one runway (or helipad ), but other common components are hangars and terminal buildings. Apart from these, an airport may have a variety of facilities and infrastructure, including fixed base operator services, air traffic control, passenger facilities such as restaurants and lounges, and emergency services. A military airport is known as an airbase in North American terminology (other countries may use the term airfield or air station in current parlance). The terms airfield and airstrip may also be used to refer to a facility that has nothing more than a runway. The term aerodrome refers to any surface used for take off or landing. The term airport refers to an aerodrome that is licensed by the responsible government organization (ie FAA, Transport Canada). Airports have to be maintained to higher safety standards. There are usually no minimum standards for a basic aerodrome.
