This is just my input about AI at KLAS, and it IS NOT a slam against the FSDT KLAS.
I've lived in Las Vegas for over 5 years, so KLAS airport scenery has always been a "high priority" for me in both FS9 and FSX. In ALL cases of KLAS airport scenery for both my FS9 and FSX, the AI will ALWAYS have major problems on the ground UNTIL a crosswind runway AFCAD is developed and used. It is due to the nature of the runway configurations at KLAS. If you get enough AI trying to operate at KLAS, on the 25's the landing aircraft will land on 25L but eventually never be able to taxi across 25R to the gates. Eventually, they will back up so bad that no aircraft will be able to land on 25L either. The line of aircraft waiting for takeoff for 25R will extend forever also, as the FS ATC will never be able to give them clearance for takeoff on 25R due to other issues. Using AISmooth can help with this, but it won't fix the problem entirely.
The above will also happen if the active runways are any "pair" at KLAS...the 1's, 7's, or 19's.
That's why I asked a few months ago if there WOULD be a crosswind runway AFCAD for the FSDT KLAS. It's really the only way to resolve the problem at KLAS. Traffic needs to use something like the 25's and 19's at the same time, or the AI is going to have major problems. You also REALLY need to use AISmooth, even WITH a crosswind runway AFCAD.
I downloaded and installed KLAS this morning and I think it is an incredible achievement. I love it. But using the default-included AFCAD, it is almost useless for higher settings of AI.
PLEASE...make developing a croswwind runway AFCAD for the FSDT KLAS a "highest priority" issue. For any other KLAS airport scenery I have, using a crosswind runway AFCAD and AISmooth HAS solved the issues discussed here.
