Romania and Bulgaria will invite the Republic of Moldova, Serbia, Montenegro and Macedonia to join the Danube Functional Airspace Block (FAB) project that will establish a joint airspace that will no longer be dictated by geographic borders, the process being part of an EU project, Mediafax informs. Last December, Romania and Bulgaria signed an agreement on setting up the functional airspace block that would integrate the two states’ airspaces. “I talked with Bulgarian counterpart Moskovski in this regard and we agreed to officially invite these states to join the Danube FAB project,” Romanian Transport Minister Alexandru Nazare stated in a communiqué. The Danube FAB agreement is the fifth of the nine agreements signed at European level for the creation of a functional airspace block. The project has a total cost of EUR 5.03 M, of which EUR 2.5 M will come from the European TEN-T Fund, the rest of the sum set to be covered by Romania’s ROMATSA and Bulgaria’s BULATSA. The European Union started the Single European Sky project in 2004, seeking to create an integrated airspace by establishing joint norms in member states.
