An airport is a designated location where aircraft such as airplanes and helicopters regularly take off and land, equipped with facilities for passengers, cargo, and flight management.
An airport is used for commercial service that includes international and domestic facilities that handle scheduled passenger flights as well as transport of freight and cargo rather than commercial passengers.
The airport also caters to non-commercial flying, including private aircraft, flight training, charter services, and emergency medical response.
There is also a military control airport used by armed forces for the deployment, operation, and maintenance of military aircraft.
