Interesting. Could it be you are looking at a conversation/list involving the incoming new order?
I know in the states, there are hundreds of airports, some quite large, that are on the FAA's ground-based NAVAID chopping block. They are VOR, VOR/DME, NDB, and NDB/DME (NPA) approach types and are (or will be) approved for RNAV procedures (PA).
I understand there are a higher percentage of airports served in European airspace by NDB's compared to the US. The retention of older ground-based NAVAIDs being driven by mainly political reasons - the mistrust of the US military-run GPS constellations. With Galileo coming in 2016, perhaps Eurocontrol is on the same path as the FAA.
