The statistics are based on the EVAIR and IATA STEADES ATM occurrence reports and their analysis. EVAIR statistics address European airspace, while IATA STEADES are global. Air operators and ANSPs remain the main data providers. We take the opportunity to thank to all of them for the continuous support and cooperation.
The EUROCONTROL voluntary ATM incident reporting (EVAIR) is the first voluntary ATM incident data collection organised on the pan-European level. Bulletins are based on the reports coming from the airlines and air navigation service providers.
