Accessing nozzle info

[Chrilith]

Hi everyone,

I'm new to this forum and also new to FS development.
I tried months ago to deal with FSUIPC before getting involved in a book writing (not related to FS...) and now I'd like to go back to a project related to FS and the Saitek Instrument Panel to create visual instruments for the great VRS F-18 model.

Now, here is my question: I need to access the following variables:

TURB ENG PRIMARY NOZZLE PERCENT:1
TURB ENG PRIMARY NOZZLE PERCENT:2

but I don't find anything in the FS2004 SDK nor the FSUIPC doc but it seems that those vars exist somewhere.

Any idea?

Thanks!
