"numerous "advanced" functions that are build into the program"Hi Bob,Intrigued by your comment, and wondering could I be missing out on some things? Can you elaborate, please?BR,Frank

Is FSNav still supported by the developer? Will there be any new versions?I imagine this would be an important consideration in evaluating the program for purchase?BR,Frank

Thank-you all for your comments/inputs. I think I have more than enough in terms of information to figure which and what product to purchase.Cheers,-Pranav

JohnI have to defend Ernie on this one. I just re-installed FSBuild and I thought I had problems with my key. Ernie responded the next day and gave me the correct key. No hassles.Regards,Harry Gentilozzi

I notice the fsnavigator website isn't functional. I wonder if it is out of business or just having website problems.

I also have both and pretty much echo the sentiments that FSBuild is for the more serious simmer and FSNav is a great in-flight utility. Something that hasn't been mentioned is if you're flying an a/c without an FMC then FSNav can act as your FMC and fly the a/c along it's route.On the John/Ernie issue, all I can say is I've never had a problem getting good, quick support from Ernie on various issues.
