However the UK IMC rating is valid, on a G reg aircraft
Reference please [
my emphasis]
The ANO does not limit IMCR privileges by aircraft registration (and I have that in writing from the CAA). Only its IFR privileges are limited to UK. The removal of the need to be in sight of surface, and the extended SVFR privileges, are valid worldwide.
...ok now I am confused, where I thought I knew before. I am a British citizen, resident in France, with an FAA Private IR. Nothing else.
Can I VFR fly a G-Reg in UK/Europe?
If you have any ICAO PPL then you can fly a G-reg worldwide VFR (ref ANO Art 26). With your ICAO (non-JAA) IR you can also fly the G-reg IFR but only OCAS which is virtually useless in France because most of the relevant routes and terminal areas there are Class D/E. It merely means that you are not illegal when enroute in IMC in French Class G.
