The summer 2008 – 2012 analyses have been based on more than 6000 reports received from more than 160 different airlines - our main data providers. Importantly the analyses also take into account feedback from air navigation service providers (ANSPs) covering approximately 15% of the manually reported data. As a part of the EVAIR ATM safety monitoring activities, this issue also covers TCAS RA analysis based on reports collected manually through airlines’ Safety Management Systems (SMS) and automatically from 13 radar stations. The Bulletin also contains other EVAIR monitoring activities such as Call Sign Similarity/ Confusion data and trends.
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.
