General question, is the TCAS in the aircraft workable? For the time I only use the A400M by Ini and only fly on VATSIM. But I dont see any traffic on TCAS?
So is it a feature or bug? 
IMO it’s one of the things that do not work at all currently.
I had close encounters both with the A320v2 and the 737 Max and I saw nothing on the display, nor did I receive any alert from the TCAS. I’m not talking about VATSIM, I use the “real” AI traffic.
The sim is a mess currently, they even managed to break things that were already fixed in MSFS (TCAS, certain transponders, contrails, Cub’s electrical systems, many aircraft lights, plus crashes when changing liveries, freezes upon exit, etc…)
