I currently have a PPL + IMC, and about 150 hours, presumably they take this into consideration when scoring your aptitude tests, but just how much better would they expect you to be?
I'm not sure that the system has any facility to take prior flying experience into account. I went to the forerunner of OASC with no flying experience in 77, and passed for RAF FlySchol, and then went a year later, 42 hours to the good, and passed for RN (P). No-one ever asked how many hours I had, and even then, so what? The aptitude tests do not involve a sim ride, or anything like it. They are rather more abstract.
