Hi,

I‘m using FlyTampa‘s KLAS and I noticed that the QNH showing in the PSXTraffic window is lower than the actual QNH in the real world METAR and what RealTraffic is displaying. 

This leads to aircraft touching down before the runway.

I checked with other airports, and everything matches correctly there. I just have the issue at KLAS.

What could be the reason for this?

Hi

I've traced the weather info coming from RT app at KLA, and it looks like a problem in there. I'll discuss it with Balthasar.

Thx for letting me know.

Balthasar: "that's an error in the METAR report" (RT receives)

So not much we can do about.

Hi kiek,

Thanks for trying. 🙂

This problem doesn't happen with the glideslope pro KLAS in my experience. Only with flytampa KLAS

I know that I've asked you this in PM, but you didn't answer. What does PSXT show as your airport when using GlideslopePro KLAS down in the bottom left corner.

KLAS Mc Carran Intl, Glideslope pro, wk=51

 Scenery won't or at least shouldn't impact the altimeter setting, but one immediate thing that I noticed was that at 26L in FT KLAS at the TDZ my elevation was something like 2170 feet asl. The Glideslope pro scenery showed me at 2066 which is within 3 feet of the plate. FT KLAS I think is still one elevation across the entire field whereas the Glideslope pro is quite varied.

I wonder.... If it was possible to manually change the altimeter in PSXT, would that move the touchdown point for the aircraft?

There is no altimeter in PSXT. Each aircraft gets it's altitude from Real traffic.

The FlyTampa KLAS is inaccurate elevation wise, it's not PSXT and it's not Real Traffic.
