WRT "how to's", my 7 year collection of notes and tips is the best i can personally do. There are yet quite a number of knowledge gaps in this collection, most of which i've managed to fill intuitively and with information found at related websites and forums like ours here. But if you can put this collection together mentally, you'll eventually have a 90% completed picture in the workings of air files and flight dynamics in MS flight sims. I'll leave it to others to compile it into a single "hardcopy" work.
