Updating default sim variables

[Clumsy]

More of a feature request for a future update. Would it be possible for the plane to also update the default sim variables, those which are being looked at by XPUIPC and other interfaces?

At the moment, Pilot2ATC, which uses XPUIPC, is not able to detect the correct altimeter setting set in the PFD. It's also not getting the right indicated altitude. It is able to detect something, but with slightly different values, so I'm guessing the plane does update those variables but maybe before it does any of the fancy temp compensation calculations? Would it be possible to get the final indicated altitude, etc, and feed those into the variables?

On a smaller note, it seems the battery/avionics variables are also not being updated (i.e. P2A cannot detect if batteries/avionics are on).

I'm not technically savvy enough to know which variables these are, or if they even exist, but having the plane update the default variables can help with integration with 3rd party applications and lessen the issues raised due to inconsistency.

Sorry, I know a lot of assumptions here, so clarifications and corrections are more than welcome.
