Lu, to be fair I think you should have included either a link to PPRuNe, or a sense of the level of the discussion.
We weren't discussing basics, or fudged over details, or "it's close enough to be able to fix or fly the helicopter". We were all being excessively meticulous, concerned with some of the finer details.
In that sense, Nick was right. The "Blue Book" (I've never read it) is quite likely technically unsophisticated. Doesn't mean there's anything inherently wrong with that book. It's just analogous to quoting "Budgie, the Helicopter" in this discussion.

Nick, I'm sure we'd all be interested to eavesdrop in the coffee room when this gets passed around Sikorsky. Try and write down some of the better ones, for our amusement.
