I would 2nd that Leezy. I have the add on's for MSFS named above and have been guilty of looking down a lot when in the cockpit. Hats off to PMDG though as they helped me out in the ATPL's answering some of those FMC and TCAS type questions for sure.
Also the 747 stand alone flight sim by Aerowinx is great fun as well. Budget on a couple of days hard study though to try and get it flying from a "cold and dark" cockpit!
