SimVars VATSIM (custom sound)

Didn’t really know where to put this question, so mods please move if there’s a more appropriate section in the SDK forum.

I am getting annoyed by those AI “combustion” sound that you constantly hear from the traffic flying on VATSIM. Especially when a plane takes off or lands that sound will always be the same as opposed to hearing a distinct sound for each flight phase.

I am able to create custom sound files using wave files and correctly pointing them in the xml/cfg file.

What I was wondering is if there is a known list of output variables from the vPilot client that I could use to determine the flight phase of the other aircraft. When Importing mdl files from FSX those Planes seem to “know” in which phase they are (you can see thrust reverse, flaps position, gear up/down).

Generally: how do I do this with custom sounds?

Any help is appreciated.
