Guidance


Methodological guidelines have been developed to assist States in assessing the economic contribution of civil aviation (ECCA) as a business sector within a given regional/local or national economy in terms of output and employment of its major components, namely aerospace manufacturing, airlines, airports, business and governmental services. Based on input-output analysis and the underlying national/regional accounting framework, the interdependence between producers and consumers of goods and services associated with air transport is measurable along the production chain.


Economic Contribution of Civil Aviation

Volume I – Global Perspective of this circular reviews the performance of air transport services at regional and global levels and estimates the direct contribution and multiplier effects of civil aviation to 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 of the guidelines 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.
