I've moved this post in the correct section of the forum.
The 15s runways has been intentionally closed for landing, following users suggestions, to both reflect normal real life usage and to have a better AI traffic distribution:
http://www.fsdreamteam.com/forum/index.php/topic,10503.0.htmlIs there a way to change how AI aircraft utilize the runways at KIAH. On 98% of the days at Bush, departures will be off of the 15's and arrivals on the westerly runways. I have ultimate traffic 2 and all of the traffic seems to take place on 15/33's. This results in severe traffic jamss and go arounds and empty terminals. I am a real world pilot and operate heavily around the Houston area and have been simming since 95.
So, following this advice, we closed the two 15s for landing.
Unfortunately, the way default ATC works, doesn't allow to have a runway "closed most of times EXCEPT when wind is really strong and there's no better option". It's either closed or it's not so, obviously, we gave preference to simulate what according to this user that is a real world pilot that operates from KIAH, is the most common situation, which also seems to improve AI distribution and gate assignment after landing.
Note that, even if they runways were opened, in YOUR example it won't have changed anything, since 8 knots (actually it's even less than that, since it's the component that counts) of headwind/crosswind is still not strong enough to have the default ATC switching runways, I don't know the exact number, because crosswind is just ONE component of a formula that takes into consideration other things like runway length, the presence of an ILS, and the other available runways, that's how the default ATC works.
