Hello, i bought both the base package and 600/700 a few weeks ago, and was wondering if the installers automatically had the SP1B update in them? or do i have to still seperatly run the SP1B for both the 800/900 and 600/700? i ask because i was browsing through my downloads folder that when i downloaded the 800/900 base package i guess the 800/900 SP1B was also downloaded as a seperate folder and i never ran the SP1B installer assuming that since i bought the plane after the service pack came out it was already the updated version? is there any way to check and see which one i have installed? thanksadam

Yes it is, check the version number in aircraft cfg. Should end in 3116 or 3118.

You can check inside your FMC also, this will tell you the version
