Hi there, I have had this problem a few times now and not sure wot causes it. Sometimes the 2 CRT screens on the main panel show up mostly black, the left one doesn't have the artificial horizon and when on map mode on the second one nothing shows.It does say IRS align time +7?Is this just a thing that happens and will be ok after a while.I hope I don't have to unistall and reinstall again, I have done this 3 times already!Kind RegardsGavin Moss

Gavin,What you're describing suggests that you haven't aligned the IRS on a Cold & Dark start. The '7+' you describe is the countdown, in minutes, before the three IRU's are aligned. Until the process completes the PFD's and ND's will not be fully initialised. There is an option that allows you instantly align the IRU's or select a delay of your chosing. Look for the 'PMDG' option in the menu bar when FS9 is up and running. You appear to have it set in realistic mode, which equates to a 10 minute delay from the start of the alignment process to completion. During this time, the aircraft needs to remain stationary.Hope this is of benefit.Neil
