Yes - its awfully simple - ratings are not licences....
There are 3 licnces - PPL - CPL-ATPL - (maybe there is even atronaut.. heheh ) and the rest are ratings!!!!!!!!
You have to do the licence test in the theory country, thats it! (since its JAA im sure some schools are exempt.... since there is nothing without an excemption n JAR)
Im sure James at aerofan would be very good at determining what can be done and not. I have talked to him a few times, and he has been excellent at repelling business, by saying that he is not sure and that I should talk to my CAA and get clearence before we start. Nothing shady there.
