anyone know what it is? I have heard 3 things, which noboby able to give me sources. I heard, vacuum (negative pressure? but what? and where is this?) 29.92, and standardized pressure.

so does anyone know? and do you have a source for it? FAA books don't have it, POH doesn't have it, and the Jepp systems book doesn't either....

I'm ready to call an instrument maker and find out...

if you wonder why I was curious. it was just one of those things that came up and everyone started making their own assumptions.
