ICAO Cir 292 — Economic Contribution of Civil Aviation.
Volume I — Global Perspective reviews the performance of air transport services at regional and global levels and estimates the direct contribution of civil aviation to and multiplier effects on the global economy.
Volume II — Assessment Methodologies contains guidance material on the underlying methodology of input-output analyses and possible applications or approaches to evaluate the demand effects of economic activities associated with civil aviation industries in terms of output/value added and employment. The first part describes how to assess the contribution of an airport to a local/regional and, if applicable, national economy with or without the expanded impact of tourism activities. The second part describes how to explore the contribution of civil aviation industries throughout a national economy with an expanded impact assessment. It also introduces the concept of a national Transportation Satellite Account.
