If the IMCR were to go, that's roughly around 3000 pilots losing IFR privileges
Yes but ICAO and a few Million other pilots would say that they should not have had such a privilege in the first place.
All this talk about high end operators is utter rubbish.
Netjets, the big American GA Fractional operator came to Europer some time ago. Now if there ever was an operator who would use the N reg if it suited then there is one. However, they in Europe operate all their aircraft on the European register, JAR-OPS and EASA and all that goes with it.
N reg may be good for the 172 flyer who will save a few grand on obtaining an IR but not worth it for the higher end players who spend lots more money and will have far more influence in cush matters.
