D'oh!
I knew I shouldn't have mentioned gyroscopic precession. But I just couldn't help myself. Lu, the intro to the Blue Book, as you quoted, is the best explanation you will get for this, and even for centrifugal: Use an easily understood "explanation" for an observed phenomenon so that you can concentrate on imparting the important info, not the labourious detail of a means to an end. but we have explained that so many times...
oops...Sorry Nick, I'll leave it alone.
Re the Centrifugal and cone angles, you spotted the myth part - centrifugal force is not real (despite Lu and Flight Safety!)
Other myths, mmmm....... do we even go near
"rotor blades emit a visible light when flying through mountain/desert air at night"?
how about
:
"helicopter technical texts are not limited by the understanding of their authors, rather they become factual and unquestionable explanations merely by being checked for spelling by an editor, and achieving print"
