I see you don't know. In fact an altimeter is calibrated to the
standard atmosphere so if the temp. is not standard it will not read
field elevation when local QNH is applied.

Wrong.

From The ICAO Manual of Radiotelephony (ICAO Document 9432) Glossary:
QNH: Altimeter sub-scale setting to obtain elevation when on the
ground

So an altimeter set to local QNH will always read field elevation *by
definition*.


No, it will read the elevation where you are. UIt will read field
elevation at the reference point.


Pretty basic knowlege for a PPL

Indeed.


Indeed indeed.
