Ok, everyone seems to be confused as to how you get these, so i'll tell you. It's not an addon, its not anything like that. It's in FS04...If you look in the Learning Center, you'll see a video where Martha shows you about pushback, and the 747 she uses has a gate near it.
All you do is this,
1. Start up Flight Simulator
2. Go into the Settings Tab on the left hand side of the screen when you launch FS04
3. Go into DISPLAY
4. In the SCENERY tab, Look to the Right side, You'll see 2 silders, one for Autogen Scenery, and another for Custom Scenery (NOT ADDON SCENERY)
5. Drag the CUSTOM SCENERY tab all the way to the right
6. Drag the AUTOGEN SCENERY tab all the way to the right.
7. There, not only will you get frame rates in the low teens, You'll get jet airways, and those little trucks, as well as barges, cruise ships and sailboats. And more buildings than you know what to do with
8. After you do this, you'll find that its easier on your video card if you make a decision between air traffic, and ground scenery...I choose ground scenery, I have NO air traffic, because it really doesnt enhance the realism as well as buildings do. Dunno why...maybe i'm jus crazy like that 😛
Have fun!
