I am actually surprised that nobody has mentioned the E-6 NATOPS. It is actually given as an example at safety school as the most ridiculously long NATOPS manual. The back end also has their own NATOPS which is also rotund. For a while, we were required to carry two full volumes of the NATOPS 000 with us while we were undergoing a modification. It had to fit in two separate binders, and we usually assigned our FETUS to carry it in a giant nav bag so that the pilots could just bring the one for the plane we were flying.
Thankfully, most of the folks in my community aren't systems nazis. I think we probably strike a balance somewhere in between the P-3 community and the tacair community. My personal take on it is that if it cannot possibly help you, be read by you, or be changed by you, then there is no reason to know it. I would much rather my 3P learn the crap that is going to matter than to rack his brain memorizing a bunch of trivia.
