The UK's air navigation services provider, NATS, has signed a Memorandum of Cooperation (MOC) with the North European ANS Providers (NEAP) organisation.
NEAP, which includes nine northern European Air Navigation Service (ANS) providers, was formed three years ago from the original Nordic Cooperation.
The organisation aims to provide seamless and cost-effective services to customers across their respective airspaces in line with the Single European Sky project.
NEAP operates through a strategy committee and a coordinating committee and has a programme office to coordinate activities on a day-to-day basis.
The group will align its activities around the North Atlantic interface, as well as with the rest of Europe.
