Hello Captains,I use Bil Bulfers FMC Guide and the Cockpit Companion (my Version covers both, the Classics an the NGs). Not very cheap but a lot of useful Information. After study this books deeply, I am every day impressed how

I don't have the cockpit companion but do own the Bulfer 737 NG FMC Guide which is a very well written book and does cover a lot of the inner FMC workings and shows the depth of the PMDG FMC ;-)...Best Wishes,[h4]Randy J.
