Thomas,

Well it might be wrong, but it will be close, like I said----not exact. And
it is a good preflight check to see if there are gross errors in the
instruments.

Your:

"it should read the same pressure as the altimeter in the Kollsmann
window when the altimeter is set to zero feet, right?"

won't even be close, unless you're at sea level, and is completely
erroneous.

Kage,

It should be close to the setting seen when field elevation is dialed
in.


I think you're wrong. When you dial in field elevation, the Kollsmann will
show the altimeter setting for the field on that day. And that, as has
been
mentioned in this thread, is not ambient pressure at the field's
elevation,
it is rather the pressure as corrected for MSL. Thus, it is NOT what MP
will show.
