Its happening to me in XP12 (2023-03-30)

Hi guys, when I load ASXP then load XP12 the Barometric pressure value doesent match from the METAR or Current location values, am I doing something wrong?

Heres a brief video of my loading process and how baro readings dont match having an error of 500 ft field elevation.

Please take a time to analyze the uploaded video.

XP12 wass using 30.72, when ASXP was showing the correct 30.22 setting giving a 500 ft altimeter error.

Cheers...

Same issue here, I noticed the higher the airport, the difference is bigger, so my guess is ASXP12 inject QNH number into XP12 as QFF, rather than actual QNH. in XP11 and P3D, there is no temperature correction so QFF is always equal to QNH, but it's nolonger true in XP12 (and MSFS) as in real life.

TBF both XP12 and MSFS have done it wrong exactly as AS did it now, yeah, new things to learn with new system.

I have the same problem

I'm having the same thing. XP12 says 1019, ASXP says 1015 and by the altimeter I can see XP12 QNH is being prioritized.

I noticed this also I was off by about 4 to 500 feet. Altitude was correct in LNM along with barometer. Even checked at 29.92. Not sure if this is with XPlane itself and transition altitudes with ATC. Flew EGNR-EHGG direct. Just to add here I notice with XPlane, when icing is involved the barometer tends to get a little sticky with or without Active Sky.

I can confirm, that closing AS and setting sim weather to clear (29.92) then loading AS the baro does change but it changes to a value higher than what AS shows it should be.
