I'll check here.
Is this only with FSUIPC 4.11? I had to make a change for FSX+SP1 because SimConnect was returning different User Aircraft IDs and SP1 was installed, and often FSUIPC would lose all contact with User Data. In FSUIPC 4.10 the change unfortunately made the User Aircraft also go into the TCAS tables, which caused continuous collision warnings in properly equipped airliners!
I fixed the latter in FSUIPC 4.11, eliminating the user aircraft from the TCAS tables by reading a SimConnect variable called IS USER SIM, or some such -- but this means I have to wait for that to be returned. Maybe SimConnect isn't returning this for ground aircraft?
I'll do some tests here later today. Last time I did check with TrafficLook I am sure I saw ground traffic, but I'll re-check.
Meanwhile, in case you no longer have it, I attach FSUIPC4.10 -- can you try it with that and let me know? Just put the DLL into the FSX Modules folder (save your 4.11 first). If the difference is between 4.10 and 4.11 I will have to review what SimConnect is doing and think again.
BTW TrafficLook is simple a demo/test for FSUIPC's TCAS tables and is just as valid for FSX as FS2004. It, along with other FSX goodies, is supplied separately now, in the FSX Downloads above.

Pete,
I have been reading this thread and decided load the Beta Ver 4.12 DLL to carry out some testing to add to Ian comments. You are not going to believe this but it fixed the problem. All AI aircraft know show up on the ground.
Thanks
