Hi,Long time user of Radar Contact and since getting FSX and my new computer up and running I have noticed a few changes. I am using Mytraffic X with settings at 50% density which I feel is realistic. In FS9 the traffic used to stop for you while taxing but now here in FSX not all traffic will stop. Just about every flight entails having to taxi through or having another aircraft taxi through me from the gate to the runway or from the runway to the gate. This is kind of ruining it for me, getting clobbered by wingtips and noses left and right. I would never be able to run collisions with other aircraft ON here. I am about to install AI Smooth for FSX for the go around issues in which I have many but from what I understand this does not sequence anything out of the gate. The other issue is that many times I have AI get stuck in my way on the way to the runway or at the hold bars. I have interact with AI checked and always rebuild scenery database upon installing an add on airport. I would rather not zap them out of the way, or taxi through them to the runway but many times I have no choice. Just the other day as I was pushing back from the gate at PANC a 747 taxied in, went right through me and took my spot I was just in. I had to laugh at that one as it started raining at -20c at the same time (another issue with ASE). My whole realism thing just fell apart in one fell swoop on that one.Sorry about the double post.

its always been a mystery why sometimes ai stop for you, and sometimes they plow through you.as you said, it used to stop, now it doesn't. so something has changed. do you know what? new ai? new settings? did you by chance turn off ms atc instead of turning ms atc volume to 0?jd

jd,Is there as setting to turn off atc completely inside fsx? I thought that was just for fs9. If there is, and I accidentally disabled it can you refresh me on where it is. I looked and could not find it. That may be the issue. I am using My Traffic X and that is the only thing I changed in the AI department.

Under settings, sound, in FS9 you leave the ATC box checked but reduce the slider to 0. In the ATC selection dialog deselect auto-open ATC Window.In FS9 only, FSUIPC has a function titled remove ATC that can be edited in for users without full registrtion. FSX does not have this,Since I do not have FSX, I'm not sure of the differences in the Settings box relating to ATC.
