Ultimate Traffic

1-No. The only time you get anything new from "UT" is when you run the update. You can add anything else that you please.
I also use GAS-Traffic, it's free and adds aircraft to the small GA airports, it uses the ones you have in your aircraft folder.

2-Read the directions, If you change something in another box it gives you a better selection.
It's difficult for me to explain without going to it.

3-New models, check your aircraft folder.

4-I don't know, I don't remember seeing green planes, it may have been the way you ran it.
I have traffic at 100%, big hit at the larger airports but I enjoy the realism.

hmmmm.... I'm still looking for the other variety of liveries to choose from. The only thing I can find is that selection under the "First One" box, and that's not nearly all the ones that are in the air for AI purposes.

Thanks for the link by the way!

Ok, I see a bunch of added aircraft under the folder in FS2004, but now can I use them?

One more thing.... I download the GA Traffic and it's not able to unzip for some reason, is there anything else or anywhere else I can go to get this utility? Thanks again

Those folders are generated by "UT" and they're being used by it, they are the aircraft that you now see at the major airports.
It seem that the designer if the app (Markus Brunner) only has it at avsim, nowhere else.
Are you using WinZip, it should work, odd. Possibly you have a corrupted file, download it again.

Yeah I'm using an unzipper I used for UT, and that worked... but nothing from that site seems to unzip properly, so I guess I'll try something else.

no matter... I downloaded winzip and that seemed to work fine, thanks again for the link

I have ut as well. I also have the flight one a340 in my flyable aircraft. Don't know why it's there or how it got there. I never fly it myself (there are better a340's for d/l at avsim.com).

The green aircraft appear if you have missing liveiers (sp?) I THINK. I seem to remember something about it when setting up ut, it asking me about this. I have seen one of these green planes before (parked at a gate), so I don't know what airline it was supposed to be.

Hope this helps.
