sources
My sources are simple. Company laptop, proprietary software and good old "Fundamentals of Flight". Wodges of manuals that fall open at the usual pages. Plus the odd snippet and gem picked up on two well-run Boeing courses under the tutelage of Lee Monson, then VP of B737s. Non disclosure agreements apply but given a simple request and time on my hands I could try and knock up a more illustrative example and pdf it to reside in the pprune notes if a moderator could advise how this is done. I can also point you at some pretty powerful software out there which is almost as good as the Boeing stuff and a darn sight cheaper although still the price of a small family saloon.
