Introduction

This document provides a set of data commonly used in economic and financial analyses and appraisals, particularly in the field of ATM.

The aim of this document is to standardise the data used in different ATM-related assessments, to facilitate data access for the different stakeholders involved and contribute to the comparability of different analyses through relying on the same data.

In this edition (10.0) the values have been updated according to the latest available information, either by adding new data or by adjusting existing data for inflation, where relevant.

Please note that the inputs have been compiled from EUROCONTROL data and intelligence, from values provided by airspace users, ANSPs, airports, IATA, EASA, and other organisations, and from other relevant documents which are publicly available.

The inputs are average values and may not be appropriate in all circumstances. The document also gives details of the sources of information and discusses the applicability and use of the values.

This document will remain a living document, and so comments and suggestions are welcome. Readers are invited to send these to economics.business-cases@eurocontrol.int.
