Hi,Yesterday I took out my Level-D after a period of not flying and apparently the TCAS did not work. I was taxiing and even took off, but the message on the display kept saying TCAS OFF, when I tried to turn the switch, it just spring-loaded back to the OFF position all the time. I also tried the Flight1 ATR and that one was having a red-coloured ring around the VS indicator the whole flight, didn't matter which position the TCAS switch had. Maybe there has been some corruption with a general TCAS file in FS, but where to look at if I want to correct it? I guess it currently happens with all airplanes having TCAS in my flightsim.Thanks a lot and I'm looking for your answer!

I just tried PMDG and that one crashes my FS to desktop as soon as I put transponder to TA or TARA. Any ideas what could be the whole reason of the conflicts?

Did any of you eventually upgrade to FS9.1? I remember that the TCAS that came with UT needed a new DLL to work with FS9.1 again.Jan

Nop, has been working nicely after upgrading to 9.1...
