It is operational in the 600/700 if you install the 800/900 upgrade. In the base 600/700 product, no, TCAS is not functional.Lee Hetherington, PP-ASEL (KBED)

It IS if you have upgraded to the 800-900. The 600-700 original release (up to SU1.3) does not have TCAS but does upgrade once the 800-900 is installed.[h4]Best Wishes,Randy J.

Using SBRelay, with the PMDG configured to use FS2004 Internal, i correctly see the traffic.Hope this helpsClaudio

>Using SBRelay, with the PMDG configured to use FS2004>Internal, i correctly see the traffic.Although I see TCAS traffic when not online, I have never seen traffic when online in the PMDG 800, though I can see it outside the window, and in FSNav with the multiplayer option logged in.How/where do you set "FS2004 internal"?* Orest-~~~~~~~~~Orest SkrypuchUAL1445 DENFOCYFD - Canada

Orest,I will link you back to a post earlier in this very thread that tells you where to set "FS2004" for TCAS. :-eek Here it is:http://forums.avsim.net/dcboard.php?az=sho..._id=51475&page=Hope it helps,

When I fly online I sometimes see the traffic. I believe that it's not the PMDG, but SB...couldn't it have something to do with all the lag when using SB. When I fly using that other program, FSInn, I don't have this problem, so I thought maybe it's all the lagging.

I don't believe lag has anything to do with this. If the aircraft is visible within SB and/or the outside view and within the limitation of the TCAS display range, then the aircraft should appear on the ND. If not then it's probably a configuration issue.

try enabling "FS2004 Internal". Mine never worked with anything else online .... cheers,Ronniehttp://ronnie.vandelaak.com/baw644.gif
