Rotorfossil thinks it's illogical. When I reached 65 I got myself an Australian licence to continue flying in the Far East. The company I am working for are bringing a British registered aircraft in for a short term contract. They would like me to fly it but I can't on my British licence because I am over 65. If they rubbed out the G reg and replaced it with a VH reg then I could fly the same aircraft with the same passengers over the same route with no trouble at all.
