Sorry for dropping off line guys. I had to go flying
Thanks for explaining for me nike - you understood.
The latest is, I met a CAA rep last night quite by coincidence. Once I explained the anamoly, he could see where I was coming from. The phones have been ringing and I am expecting a call from CAA to define the requirement. It seems as though it will be resolved and the initial response I received from the office may have been incorrect.
If you took the reasoning that currency couldn't be cross credited between different licences, then in theory, even an ATPL or CPL holder, on a class two medical, could not have exercised the priveleges of a PPL without sitting Air Law again because they are different licences. I don't think that is what is trying to be achieved.
I'll keep you posted when I hear the final outcome.
