I'm currently using FSX's ATC right now with Ultimate Traffic 2. One issue I get is while in mid-air I'm getting a lot of close fly-by's, within 1000 ft usually. Once I even over took another slower 737. Flew over him by a few hundred feet.

 

 

I tried running aismooth for my flights but it didn't seem to help.

 

It's mainly annoying with FSX ATC cause I constantly hear the traffic in sight stuff for all these planes flying by.

 

Would something like VoxATC better manage traffic so we're not all flying that close together?

The only way to avoid what you describe is to avoid cruising altitudes that UT2 use. I tend to fly at FL360 and above. I still get the odd TCAS alert, but not as often. As for AI smooth, that is more for approach and take off. Not intended as traffic avoidance at cruise altitude.

Well, I use Just Flight traffic X and this does not happen often. Either way I wish situations like this happened more often, it makes cruising at 30,000Ft more interesting. :lol:
