As a student it's pretty confusing if you're learning the wrong services!
I'm assuming (so am probably wrong) that a new edition has been published (FlightStore says 2011), but it doesn't seem to be circulating yet from certain places. If I were doing it again I wouldn't bother with the R/T book anyway, I'd just download CAP 413 and the GA supplement.
My 2009 Trevor Thom covers the new ATSOCAS stuff, so a 2011 edition certainly would. To be fair, there's a lot of stuff in the book that isn't in the CAP 413 supplement - it's far from useless.
