The European Commission has formally requested 18 member states among which Bulgaria to improve their Functional Airspace Blocks.
Austria, Bulgaria, Croatia, Cyprus, Czech Republic, Greece, Hungary, Ireland, Italy, Lithuania, Malta, Poland, Portugal, Romania, Slovakia, Slovenia, Spain and United Kingdom, members of six different Functional Airspace Blocks (FABs) have been requested to improve their FABs, a common airspace arranged around traffic flows rather than state boundaries. FABs are a crucial step towards a more efficient, less costly and less polluting aviation system in Europe, the official press release of the EC states.
Commission Vice-President Siim Kallas, responsible for transport, said "We have to finally overcome national borders in the European airspace. FABs are a necessary, vital component of the Single European Sky. Right now these common airspaces exist only on paper; they are formally established but not yet functional. I urge Member States to step up their ambitions and push forward the implementation of the Single Sky"
All EU Member States should have implemented their FABs by 4 December 2012. The FAB between Italy, Greece, Cyprus, and Malta is still being formally established, whilst the State Agreements establishing the FAB between Austria, Czech Republic, Slovakia, Slovenia, Hungary, Croatia, the FAB between Bulgaria and Romania (DANUBE FAB), the FAB between Lithuania and Poland, and the FAB between Spain and Portugal, and the UK/IRELAND FAB have come into force.
