…been reduced to 967. The United States is decommissioning approximately half of its VOR stations and other legacy navigation aids as part of a move to performance-based navigation, while still retaining a "Minimum Operational Network" of VOR stations as a backup to GPS. In 2015, the UK started to reduce the number of stations…

"RNAV (GNSS)" becomes "RNP", and "RNAV (RNP)" becomes "RNP AR". Sweden is one example of a member state who has already adopted the new correct RNP-designation for the PBN implementation.
