Hello Pete,

I have a question concerning the QNH, can we read the value of the QNH entered in the PMDG 747 plane and compare it with the real QNH?

Thanks in advance.

The QNH is the "real" local pressure standardised to sea level. The value you set on the BARO knob on the EFIS in your aircraft is the value you want to use to adjust for flight levels or whatever (maybe to QFE for altitude above an airfield when training).

The value you set is in your cockpit (also known as the "Kollsman") is your altimeter setting, and is readable in offset 0330 in FSUIPC offsets. I'm pretty sure this will apply to the PMDG aircraft too, but maybe only for the captain setting -- the first officer side can be set separately (offset 0332).

Thanks for your answer.

I'd like to compare the QNH in the aircraft to the QNH of ActiveSky or any other real QNH.

Thanks in advance

if you had a look in FSUIPC Offsets Status.pdf and search for QNH you will find

0EC6 2 Pressure (QNH) as millibars (hectoPascals) *16.

0F48 2 Pressure (QNH) as millibars (hectoPascals) *16.

34A0 8 Sea level pressure (QNH), double float
