Old Farts and France
I had to leave big flying on reaching 60 because of the French rule but found other, smaller, aircraft to fly. The French changed their rule just afterwards and so I was able to fly over France up to 65. Operated on numerous flights into French airports but never got ramp checked so cannot say for sure but it seems to me you re OK if you are using non French licence in Non French reg aircraft. Now retired at 65 because of CAA licence
