The analyses are based on more than 8000 reports received from about 160 different airlines - our main data providers. Our data base also encompasses ANSPs’ reports related to specific types of events e.g. ‘Call Sign Similarity’, ‘ACAS RAs’, ‘Laser’ etc. Our data set also includes ANSPs’ feedback on the airlines occurrence reports. Feedback consists of narrative parts and in many cases of radar screen shots and voice records/transcripts. Having occurrence reports and feedback, gives the opportunity to EVAIR to reconstruct events and to identify their causes as one of the most important part of our analysis.
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.
