Introduction

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

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

In this edition (10.0.3) the values have been updated according to the latest available information, either by adding new data or by adjusting existing data to inflation, where relevant.

Please note that the standard 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.

They 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 [email protected].
