| Statistical concepts and definition | For statistical uses, departures are equal to the number of landings made or flight stages flown. A flight stage is the operation of an aircraft from take-off to its next landing. A flight stage is classified as either international or domestic. The international flight stage is one or both terminals in the territory of a State, other than the State in which the air carrier has its principal place of business. The domestic flight stage is not classifiable as international. Domestic flight stages include all flight stages flown between points within the domestic boundaries of a State by an air carrier whose principal place of business is in that State. Flight stages between a State and territories belonging to it, as well as any flight stages between two such territories, should be classified as domestic. This applies even though a stage may cross international waters or over the territory of another State. Freight t-km performed measures a metric tonne of freight carried one km. Freight t-km equal the sum of the products obtained by multiplying the number of tonnes of freight, express, and diplomatic bags carried on each flight stage by the stage distance. For ICAO statistical purposes freight includes express and diplomatic bags but not passenger baggage. Air freight is the volume of freight, express, and diplomatic bags carried on each flight stage (operation of an aircraft from take-off to its next landing), measured in metric t times km travelled. |
| Relevance | Transport infrastructure – highways, railways, ports and waterways, and airports and air traffic control systems – and the services that flow from it are crucial to the activities of households, producers, and governments. Because performance indicators vary widely by transport mode and focus (whether physical infrastructure or the services flowing from that infrastructure), highly specialized and carefully specified indicators are required to measure a country's transport infrastructure. The air transport industry is a vital engine of global socio-economic growth. It is of vital importance for economic development, creating direct and indirect employment, supporting tourism and local businesses, and stimulating foreign investment and international trade. Economic growth, technological change, market liberalization, the growth of low-cost carriers, airport congestion, oil prices, and other trends affect commercial aviation throughout the world.
