Do I not dislike altimeter questions?
QNE is 1013 millibars. Set at transition level and reset at transition altitude.
All aircraft with 1013 set will indicate a flight level which is then a standard for all aircraft with 1013 so set.
QFE is that setting which will allow the altimeter to read 0ft at the touchdown reference point. It was much favoured by the military and is still in use.
Therefore, go around height might be at 200ft, altimeter reading.
QNH is the setting which will allow the altimeter to read airfield elevation at the touchdown reference point.
It is used at high airfields such as Johannesburg where it is not possible to wind down the altimeter sufficiently to allow 0ft to be read on touchdown.
Therefore go around height might be at 5,780ft, altimeter reading.
Does that help muddy the waters?
