All of my Trevor Thom books are at various friends houses as they are in various stage of their PPLs. I seem to be a library for PPL books...
Anyway as a suggestion go and ask at some flying clubs at your local airfield if anyone has any Trevor Thom or Jeremy Pratt PPL books for sale. I'm sure they'll let you put up a notice on the notice board.
When are you going to Naples?
If at the end of July / beginning of August then I shall be there with a friend who is completing his JAA PPL.
He's passed his Air Law and Meteorology exams now and is taking his Human Factors exam on Tuesday. He can't wait to get these exam over and done with.
