Did you read the link provided by
Fitter2 at the very first post in this thread?
The first two paragraphs of that answer your question:
It would appear from a recent JAA FCL 001 core group meeting held at EASA’s headquarters in Cologne, that with the exception of the UK, Europe doesn’t want the Instrument Meteorological Conditions (IMC) rating.
So what? UK pilots may ask. It doesn’t bother us; we’ll just carry on exercising our IMC privileges in the UK and leave the rest of Europe to do their own thing. Actually, no. They won’t. When EASA takes over Flight Crew Licensing in the near future, all National flying licences and ratings will cease, either to be replaced with Europe-wide equivalents, or removed entirely. And without the endorsement of other Member States within the JAA community a licence or rating cannot be adopted by EASA.
