Dear Jonathan (and John who replied offline),
"* Would it be acceptable and useful to follow some other kinds of standard name and call this air_pressure_expressed_as_altitude?"
Actually, I think not. The goal of this quantity is really to describe altitude, not pressure. This is different from a "mole_fraction..._expressed_as...", because there it is really the same thing with a simple conversion factor. So, I would still prefer "barometric_altitude".
Concerning the second name, I see that we need to define this better. Actually, it doesn't seem as straightforward as I thought... We will take your comments into account when rephrasing the proposal for the second name.
Best regards,
Martin

Dear Martin
Obviously these quantities are useful. I have two suggestions for your
consideration, hoping I have understood the idea.
* Would it be acceptable and useful to follow some other kinds of standard name
and call this air_pressure_expressed_as_altitude?
* above_ground doesn't seem specific enough to me, because you don't mean the
local ground, which we would usually call "surface" in standard names (i.e. the
bottom of the atmosphere). To be more precise, we could use something longer
such as wrt_surface_at_flight_origin. It refers to a particular time and place.
Best wishes
Jonathan
