Post by Pierdail » Tue Mar 24, 2020 4:39 pm

Hi,

I encounter a small problem, the setting of the QNH of the terrain, gived by the ATIS does not correspont with the airport altitude
This morning at LFBP QNH: 1019, terrain altitude: 617', with this setting, the tape altitude on PFD give 630'

Regards

If you use tooltips, you'll see the actual set QNH differs by 1hpa to what's displayed on the altimeters. I think I saw this mentioned as noted for the upcoming SP somewhere.

Hi,

It is not a problem, it´s a feature. Pilot and Copilot altimeters differ by small amount and also regarding to exact altitudes. ESIS altimeter reads similar to Copilot as it uses the same pitot data.

It's not a left-right difference that is the problem, if you press B to use the FSX/P3D "set local qnh" function, the screens display a hPa that is 1 off of what is reported at the airport. The sim tooltips shows you what the actual current pressure setting is, 1hPa off of whatever the displays show. This is not a feature, this is a bug, no matter the intent.

Ah, that is different to what the OP reported.

I checked the code and found that HPA baro reading was incorrectly rounded. Now it is fixed.

Thanks!
