Hello,I am looking to purchase the PMDG 747, and I can see there are two different types, the 747-400 and the 747-400F. I really like flying the cargo type of planes, and was wondering if the freighter version is the same as the passenger in the cockpit/system of things. Does it require two different start-up and other types of procedures, or can they use the same checklist and manuals? In the end, I think I will buy . (I've seen a lot of youtube videos of just the passenger plane, and there are not really any of freighter vids that have tutorials). I am also considering to get the AOA video of the 747. Tyler
