By the end of 2009, 63 SUMMER SEASONS 2006-2009 EVOLUTION airlines were providing ATM incident reports to EVAIR. The airlines which contribute to EVAIR account for 50% of the overall European EXECUTIVE SUMMARY air traffic. The statistics in the EVAIR Safety Bulletin No 4 cover the summer Main trends periods (April - September) 2006 to 2009. The statistics are based Eight main ATM contributors are used as the basis for monitoring: on the ATM/CNS incident reports collected manually and ACAS RAs collected automatically from one Mode-S radar station.

The role of EVAIR is to facilitate the feedback of collected incident reports. The graph below shows these process by keeping up to date safety focal points on the side of the increases of manually reported incidents in absolute figures. airlines and ANSPs; forwarding ATM incidents to ANSPs or airlines involved; asking for the reply and, when/if the feedback arrives, forwarding it to an appropriate address.
