TCAS
What does it look like? Does it work?
LiveTraffic's aircraft can be made available on your plane's TCAS and to other plugins, e.g. to display them on maps. Since X-Plane 11.50 there is a new dedicated mechanism for this purpose called TCAS Override. This new approach makes workarounds like configuring AI aircraft superfluous and allows to report up to 63 aircraft as compared to previously 19.
In earlier X-Plane versions (i.e. up to 11.41), LiveTraffic falls back to the previous way of emulating TCAS, which will require you to set up AI Aircraft in X-Plane's aircraft settings.
There might still be older software around that cannot deal with more than 19 active TCAS targets. Please update Little XPConnect, AviTab, and XHSI to latest versions, where this is fixed. A crash with FF A320 is being investigated.
Here are 4 screenshots showing off the functionality of TCAS and multiplayer planes:

Showing off TCAS Override with uncounted (clearly more than 19) TCAS blibs...while there were no AI Aircraft configured.

What a dangerous situation looks like with another plane approaching and nearly hitting you...bad piloting skills

Does it work?

This list bases on feedback before introduction of TCAS Override. Consider it indicative only at the moment. TCAS Override has been designed with plugins using the classic multiplayer approach in mind, so one should expect that all implementations, which worked previously, will still work. But there are no guarantees as there might be sideeffects of the new way.
The following feedback I received. The last column "Uses TCAS Targets" tells you what we know about if that plane/tool is already adapted to use the up to 63 TCAS targets as data source, ideally with a specific versions since when it works.

*) For Pilot2ATC there are reports that it would show no planes when no AI Aircraft are configured. This seems to be a bug in XPUIPC, which is used to connect Pilot2ATC to X-Plane. Until that is fixed you need to have AI Aircraft configured when Pilot2ATC starts up.
