Hello, A newbie question: I am running squawbox to fly on VATSIM. Does the NGS TCAS works on VATSIM ? Regards Karim

Yes. SB places AI planes to show the online people. and the TCAS gauge will recognize any AI traffic if certain parameters are met (altitude, distance away, ...)

Just ensure you set it up in the fmc, as you may inadvertently filter out the traffic.

Yes it does. Beautiful, isn't it?
