Changing hpa/inhg sea level pressures

The pressure is always at 1013 / 29.92

Zitat von iFlyHigh

The pressure is always at 1013 / 29.92

This is the QNE pressure.
“QNE : The term refers to the indicated altitude at the landing runway threshold when 1013.2mb (29.92 inHG) is set in the altimeter. The standard and globalized mean sea level pressure value is 1013.2mb (or 29.92inHg). Pilots use QNE when their aircraft reaches higher altitudes. Above transition altitude all aircraft sets 1013.2mb to provide a common datum for vertical measurement.”

The QFE setting: On the runway, you set the altimeter to 0.
”QFE: QFE is the mean sea level pressure corrected for temperature and adjusted for a specific reference point of an airfield or the point needed. Generally, for aerodromes the highest point of the runway is set to be reference.”

Imho the QNH is not impemented in this simulator.
“QNH: QNH value is the pressure value measured at a location and reduced down to mean sea level. More clearly when an aircraft sets QNH value on altimeter while a taxi movement at an aerodrome, then it will show the aerodrome elevation above mean sea level. QNH is the widely used pressure settings in global aviation world. It is given as a regional pressure setting and should be reset with new values if you leave its area of reference into a new QNH pressure region.”

I hope this helps and I didn't make too many mistakes…

4500 m QFE over Locarno.

This can also be a QNH solution...

Edit: But in this case, the altimeter will show a wrong value on the ground and not the altitude of the airport. Because there is no real weather in the simulator, as Jet-Pack wrote above, only the international standard atmosphere.
