Please refer to CAP493 Annex A Page 2.

Crash one, you would need to obtain/calculate/deduce a QFE for Kingsmuir. If using the Leuchars QNH then the Kingsmuir QFE might be approximately 14 hPa lower, ie. approximately 944 hPa, and possibly off the subscale. From the table QFE 944 hPa gives a QNE of 1946 ft, ie. the altimeter would indicate approximately 1946 ft on landing.

Unlike QNH and QFE which are altimeter settings, QNE is an altimeter reading - it is an indication on your altimeter at landing when you set it to 1013.2/29.92. Of course it is as changeable as QNH and QFE, so you need to get it each time from someone. And then, when landing:
instead of setting QNH on alt and reading THR elev when you land, and
instead of setting QFE on alt and reading 0 when you land,
you set standard setting 1013.2 and read QNE when you land.
Did I get it right?
Correct.

Dave, a QNE is not a pressure setting. If you are the Dave Wilson I trained at Farnborough in the early eighties you have since become a very experienced GA pilot, so should therefore know this!
