As for it's place within Europe, It's quite difficult to see how in practical terms that the EIR is an improvement of the current "VFR-on-top" rights that a French PPL holder has as part of his normal PPL
Well I would be in favour of the "allow access to all classes of airspace" as this would mean I could fly from crappy weather in England to sun in the south of France at a decent altitude. But all these silly rules will be unworkable in reality as only a pilot can determine actual weather conditions.
I think EASA should be scrapped and the FAA paid a huge fee (equivalent to all the salaries this whole process is generating, so it would indeed be a huge fee) to reorganise Euroland, which they could do in one easy swoop - by posting a copy of the FAR/AIM to Brussels. This would save the Eurotaxpayer millions, would give clear, concise, sensible rules to a frankly disjointed, cobbled together Quango.
I also don't see how the UK can retain its frankly messed up airspace classification in one harmonised (NB: harmonised - if you ignore the French, British, Norwegians, etc.etc...) EASA run operation.
It is a waste of money, will do nothing to aid safety, will cause untold problems for pilots and operators, and is all a bunch of bolleaux as le Francais would say.
