I need to garner some information about a specific aircraft's technical performance that I cannot seem to get in another way.  I am working on programming some stand-alone gauges for simpit use.

I need to look at the levels in a couple of gauges to see where the gauge goes into the "yellow zone" and the "red zone" for the values of parameters like hydraulics and such.

Is there a way to easily view these values within an existing gauge?  I think these gauges are "traditional" ones, not the newer xml gauges.

Appreciate the help.

best,
