Yes I have the manual as well but its all double dutch to me. I have recently purchased Bangkok INT. airport which is totally huge in size. But its empty,no traffic

 

Any advice on how to add traffic using UTX would be appreciated

From the UT Forum: http://ultimatetraffic.flight1.net/forums/forum_posts.asp?TID=8649&KW=Suvarnabhumi&PID=48925&title=changing-vtbd-to-vtbs#48925

"This is how you do it. First open UT2 Power Pack Program and go to Airport Modification tab.

Now you must have VTBS airport AFCAD already in you addon scenery. If not you can download from various websites like Avsim.com or Flightsim.com. Click on the Airport Modification tab and then Click on Create New Airport and type all the required information on the airport, such as longitude and latitude etc and save that information. In the same Airport Modification tab, click on the Remove by IATA circle. Then find in the Select IATA tab BKK and the current ICAO

will read VTBD (the old airport). At that point, click on Save Modifications, it will ask you that

you are removing traffic from this airport and cannot be redone etc. Just click OK. The traffic

is now no longer at VTBS for BKK. Now click on Modify ICAO code on IATA airport circle and find BKK (it might be two BKK, but that's ok select one) then goto Select ICAO and find VTBS (again

it might be two, just select one of them) and after that click on Save Modifications. Then at

this point, click on Check for Conflicts. It will find all conflict around 400 plus conflicts, then

click Resolve Conflicts and Power Pack will start setting up BKK traffic for VTBS airport. This

may take a few minutes, but when finished all traffic for BKK will now be Suvarnabhumi (VTBS).

There you have it. Hope it works out."

Thanks Luis for making that detailed effort, I will have a crack at now .

You've got no traffic at Bangkok? Let me check and see if I do.

and I have traffic x which is a totally different interface to ultimate traffic 2. I m reading the avsim review, they usually give a detailed description
