What does the functional airspace block with the Irish Aviation Authority involve?
The UK/Ireland FAB or functional airspace block, the first to be set up under Single European Sky, became operational on 14 July 2009. A functional airspace block, or FAB, is a sector of airspace covering more than one country which is operated and managed as a single unit.
The UK and Irish governments announced in June 2008 that NATS and its Irish counterpart the Irish Aviation Authority would be operating the world’s first Functional Airspace Block, as part of the European Commission’s Single European Sky initiative. The announcement was the culmination of four years’ work by NATS and the IAA to develop their adjoining airspace into one seamless operation. The joint approach enhances the safety and improve the efficiency of the airspace, to the benefit of the airline industry and passengers.
