As usual, when it comes to aviation matters, we on the West Bank of the Salt Water Divide see things a bit differently.
One of them is how the FAA treats the Military Aviator when it comes to licensing.
But then my recollection of the UK system reminds me of why ya'll just do not....and shall. not ever get it figured out.
Take a read of our Federal Air Regulation that deals with this licensing situation.....perhaps ya'll night consider copying what we. have done.
Now pay attention....when we talk "Type"....we have a completely different but much simpler system of "types".....ie we do not "type" for aircraft weighing less than 12,500 pounds....like Gazelles, Hueys, Jet Rangers, 350's.
