Correct Bally, they're only certified for Area Navigation to RNP5 as delivered. New regs in the pipeline will bring in RNP1/3 within Eurocontrol before much longer, but it is noteworthy that in some countries, ATC already offer what they call 'Precision' RNav approaches - at Frankfurt for example - even though there are hardly any aircraft certified to better than RNP5.
And don't forget there are moves afoot to shut down existing VOR stations progressively, in the USA as well as other parts of the world. There is a tendency for ATC to move faster than the operating industry these days and Eurocontrol in particular doesn't care whether the technology is available on the aircraft or not - look at 8.33KHz Comms, RVSM, RNP5 and so on. Not to mention the US congressional mandate of a non-existant TCAS.
No, VOR is going the way of Terranosaurus Rex and Mr. Sperry's Flux Gate I'm afraid, so we'd better get used to the idea...
Ruslan, the US may have used 'Selective Denial' in Afghanistan but in a war zone VOR wouldn't be left running without intervention either. That's why military 'heavies' tend to carry the much mocked human navigator.
