Granted I'm not up on the intended changes to the structure in 2010 or whenever, but why do they need to scrap the rating?
It's a UK only rating, so presumably it's not going to impact on any other member states at all - and possibly pilots in those states might welcome such a rating.
The question should surely be "does anyone want a UK style IMCR in their country - if so, fine, if not, fine" rather than "the UK have something we don't - BAN IT!"
I don't see the rationale behind scrapping something useful which no other country currently implements - what's wrong with us continuing to do it?
