As you can see Garry...I didn't have them switched on. But the captions in the full post reveal that with 100% on the slider there were 747 aircraft in the local area and that made it almost unflyable...I knocked it down to 20% (about 150 aircraft) for the landing and that was a slide show with the other settings I had for good pictures, so the landing was not easy
I see the stock airports are still crap..and thats Heathrow!
re FS9 well see my previous pictures of the Trident in FS9 to FSX that will answer your question
