The manual indeed is available at the website. The URL is whatever relevant one turns up when you search for "PSS 747" and "Simulation", or reasonable variants thereof.
I'm not being snide. I'm on IE at the moment but my bookmarks are all kept in Netscape, which has fewer security holes and which is what I use for email and searching. If I were on Netscape now I would give you the URL.
For the benefit of other readers ...
Why am I on IE now rather than Netscape? Because IE has a stronger download (and download/resume) capability than does Netscape, and it is better at displaying the FlightSim forum pages.
Even though IE has security holes I am reasonably safe so long as I don't fire up Outlook Express or any of the other Internet Explorer attachments.
Here ya go...
