Will WAAS-ified GPSs be able to drive the GS needle en route?

Not trying to be argumentative, but a simple look at the altimeter
provides all the info you need to know.

Even more to the point, a look at the altimeter provides you with the
correct information, namely pressure altitude.


Uh... Stefan..., a look at the altimeter provides you with *indicated*
altitude. It only shows *pressure* altitude if the altimeter setting is
set to 29.92

All altitudes shown on an altimeter are "pressure altitudes" (as opposed to
true altitudes) since the altimeter is an air pressure guage marked in feet.
