For weeks I have been looking for a good flight plan program and by chance stumbled onto Plan-G. I have been reading posts and looking around on the forums and have some of my questions already answered but have a few I haven't found yet - I have not downloaded Plan-G yet which is why I am asking to be sure I know what I am doing before I start which is really the question  :)

First, what all do I need to do? What do I really need to download and why? EXAMPLE, I read about XPUIPC. Do I need to download that and why? Okay, once I've downloaded all I need, what do I do with it to get it to work? (maybe there is a manual I should read before I start; if there is, I haven't found it yet and I will keep looking.) Finally, does Plan-G integrate with the on-board FMC or FMS? How about Javier Cortés' UFMC?

Thanks, sorry for my stupidity but being a newbe here I guess it is to be expected somewhat.

Thanks, Don
