Helilad - I believe the JAA use his book, but it does need a supplement for the exams, else why do Bristol add a supplement for their military bridging course? As a standalone non-exam book, though, it's good enough - and you do need to read it twice! My own preference for a compact book, if you can get an old copy, is John Fahey's The Helicopter and How It Flies, supplemented, of course, by Shawn's Books!
I would not be at all surprised to hear that the JAA also refer to Rotary Wing Flight, which was distilled from US NAvy material. I will ask them next time I speak.
Farmpilot - PM me for details on such a book.
