P3D V4 Enhancements

Hey Robert,

Sorry for the delayed response, but I was hoping others would chime in. As for AI traffic, I'd been waiting for an update to Ultimate Traffic 2 that would work with p3dv4, as I didn't like the fiddling of trying to get the older version to work. Finally they came out with UT-Live, the p3dv4 version. I believe, as with several other addons, this requires additional cost for the upgrade, but it restores the wonderful liveries of real-world airlines in configurable AI traffic.
