I recently upgraded from fs2002 to fs2004 (fs9) - yep, I'm a late-bloomer - and can't locate any .pdf's other than the 30-pg basic manual that also comes with fs9 as hardcopy. In fs2002, I made huge printouts of Ron Machado's Ground School lessons, an Aircraft Handbook covering all the included planes, a "Getting More from fs2002" book, etc. I looked on all four CD's, searched for .pdf under my install area, even searched these forums for "aircraft handbook" and "where manuals". Still no joy.Where are these manuals, or did M$ simply not include 'em in fs9?

Everything is in web format in the learning center in the game. You can also browse to all the files. They are located under the fsweb directory in your fs2004 folder.
