An airport is an aerodrome with extended facilities, mostly for commercial air transport. Airports often have facilities to store and maintain aircraft, and a control tower

An airport consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as runway for a plane to take offor a helipad and often includes adjacent utility buildings such as control towers, hangarsand terminals.

Larger airports may have airport aprons, taxiway bridges, air traffic control centres and emergency services. In some countries, the US in particular, they also typically have one or more fixed-base operators, serving general aviation.
