One thing that you need to save for FSX IF you want to keep the record of all your flights, is the logbook.BIN found in (My) Documents\Flight Simulator X Files.

There is an editor, I have it somewhere on my one of my HDD's, that allows you to edit the entries a bit more than the default one in FSX itself. Adding the two together ? I don't think it can do it. I'll have to look for it to find out.

I learned long ago to back up that pesky logbook.BIN file. I zip it up on a regular basis and IF something goes horribly wrong with my logbook, I can unzip my backed up one and I will only lose a dozen or so flights.

You can download it here: http://simviation.com/1/download-file?file=logbookedit.zip

Hope this helps.
