I'm surprised that you would want to know about this VIKING. I only say this because your profile states you are a line pilot on the 744 (?) and with an atpl already. I think that in all honesty you are in the right forum on here at least!
I studied Human Performance for the JAA exams and it was extremely interesting but also extremely easy with minimal revision. I would offer to lend you the folder, which covers the entire JAA syllabus and everything that could be examined, but you have failed to tell us where your location is. If you are anywhere near Oxford then I would be happy to lend it to you.
