In preparation of the 12th ICAO Air Navigation Conference (ANConf/12) in November 2012, the European Commission, SESAR Joint Undertaking, Eurocontrol and European Aviation Safety Agency started a coordination group to consolidate the European position on interoperability. The aim of the group is to define clear messages and to drive developments proactively as to prepare a strong input on interoperability with standardisation bodies such as EUROCAE and finally ICAO. The group will work in coordination with the US counterparts.
