Some Basic Question about QFE
Assume
Elevation 931ft
QNH 1003Mb
Temperature 9 'c
What would the QFE setting be on the altimeter if aircraft on ground and altimeter=ZERO
Also What is the density Height at this port?
I am beginner of this area

A quick estimate (assuming 27 ft/hPa) gives a QFE of 968 hPa. The temperature doesn't affect the QFE-QNH relationship.
The pressure altitude is about 1200 ft (again assuming 27 ft/hPa). The temperature is approximately ISA-3.5°C so the density altitude is about 800 ft (assuming a density altitude change of 118.8 ft/°C ISA deviation).
