Introduction to Air Transport Statistics ICAO Aviation Data Analyses Seminar Middle East (MID) Regional Office 27-29 October Economic Analysis and Policy (EAP) Section Air Transport Bureau (ATB) ICAO Strategic Objective: Economic Development of Air Transport Main terms and definitions used in air transport statistics Civil Aviation Activities Classification Civil Aviation Activities Commercial Air Transport Services Distinction very blurry in Europe and North America May distort annual growth figures In many other States distinction still exist Poor reporting of non-scheduled traffic Non-scheduled traffic difficult to estimate Scheduled vs. non-scheduled Commercial air transport operator: An operator that, for remuneration, provides scheduled or non-scheduled services of passengers, freight or mail. Also includes small-scale operators, such as air taxis, that provide commercial air transport services. Operating carrier: Carrier whose flight number is being used for air navigation control purposes. All operational and traffic items should be reported, including code-shared, franchised, pooled, blocked-off charter, blocked-space arrangements, joint services and leased aircraft services. Traffic: For air transport purposes, traffic means the carriage of passengers, freight and mail. Some definitions used in air carriers statistics Aircraft departures: Number of take-offs of aircraft. For statistical uses, departures are equal to the number of landings made or flight stages flown. City-pair: Two cities between which travel is authorized by: a passenger ticket or part of a ticket (a flight coupon) or a shipment document or a part of it (freight bill or mail delivery bill) Some definitions used in air carriers statistics Distances: Aerodrome-to-aerodrome great circle distances should be used in all items involving distance Great Circle distance is defined as the shortest distance between two points on the surface of the Earth by using the Vincenty distance formula associated with the World Geodesic System – 1984 (WGS 84) adopted by ICAO (Annex 15). The latitude and longitude of aerodromes can be taken from aerodrome data published in Aeronautical Information Publication (AIP). Some definitions used in air carriers statistics International when one or both terminals are in the territory of a State, other than the State in which the air carrier has its principal place of business. Domestic when both terminals are in the territory of the State, where the air carrier has its principal place of business . Includes flight stages between the State and the territories belonging to it, and between two such territories. This applies even though a stage may cross international waters or over the
