scope:

The manual provides an overview on how to conduct economic and financial analyses for aviation infrastructure projects, with a particular focus on cost-benefit analysis. It takes into account the existing guidance on cost-benefit analysis, business case and economic impact analysis in the Airport Economics Manual (Doc 9562) and the Manual on Air Navigation Services Economics (Doc 9161), and aligns terminologies with a view to achieving a common understanding of these concepts. Supplementary material is provided in the appendix and provides concrete examples and references in conducting such analyses.

The guidance in this manual is presented in three chapters. Chapter 1 provides definitions on cost-benefit analysis, business case, economic impact analysis and cost-effectiveness analysis, and explains the difference between each other. Chapter 2 provides guidance on making decisions on when to conduct a cost-benefit analysis or business case. Chapter 3 describes the scope of a cost-benefit analysis and the process in conducting the analysis by steps. References to existing guidance and its application to specific aviation investment projects are included in the appendices, which will be reviewed and updated periodically.
