Delivering operational value to air navigation service providers (ANSPs), airlines and other partners is the core of EUROCONTROL’s work. At the seventh edition of the NM B2B Web Services Technical Forum more than 430 participants from 53 countries discussed the range of solutions that EUROCONTROL’s Web Services offers for the aviation community including NM B2B - the interfaces the Network Manager offers promoting business-to business interoperability for airspace, flow and flight services. Part of the conversation was the question on how B2B services and their performance will need to adapt to meet the requirements of the users in the future.
