Hello, I would like to know why I keep getting messages FSX because of the HPA settings, for example the setting VTBU (Thapao Thailand) I read in PFPX the QNH is 1006

 when I set in FSX I always get the message: Your altimeter is set Incorrectly?
I want to know what I'm doing wrong please ...

I think your actual weather datas loaded not correct. If you have a 1013 environment in your sim and you set the QNH to 1006, you are under the apron.

As the weather changes, so does the air pressure. Your altimeter uses air pressure to determine how high you are. In order to adjust to variations in air pressure, you need to adjust your altimeter setting. In FSX, you can press the B key and this will automatically be done for you. Different countries have different altitudes above which you need to set a standard pressure (which can be quickly set by the 'STD' button in the middle of the altimeter setting knob). Below those altitudes (18,000 feet in the United States, as an example) you need to set "local pressure." If you're not using ATC, you can look at a METAR to determine this setting.

Above, the METAR indicates that you should set your altimeter to 29.72. Since (I'm guessing) you're over in Europe, the values will be given in hPa instead of inHg, so instead of 29.72, the value would look like this: 1006.

 

Using EDDM as an example:

EDDM 151650Z 08004KT 040V110 CAVOK 26/14 Q1019 NOSIG

 

The altimeter setting would be 1019.

 

 

 

The question you've asked is pretty basic, to be honest. So, if you're really trying to get the most out of our products, I'd suggest looking into some basic information/lessons to be sure you're actually enjoying the simulation and not getting stuck on such basic elements:

Thanks, what exactly do you mean with the latest weather update please?

Thank you, i found the URL, METAR: VTBU 151830Z 23006KT 9000 FEW020 BKN300 29/22 Q1006 A2972

After clicking on the std knob, 1006 is changing in:

I have to learn more about this matter.

First, what do you use for the weather injection? Default weather (none), real weather through fsx, active sky... ?

 

If you don't use anything (default weather), it means that wherever you are, altimeter setting will 1013 hpa at anytime and you won't bother with real setting. However, if you use a weather injection engine, then you should check the METAR at the airport that comes along with what you use.

 

If you use active sky for instance, check the METAR from active sky. If you use the weather from fsx, check the ATIS in fsx.

Thank you all very much, I did not know I had to turn on this feature :-)

 

Equal afterwards, the appropriate QNH on the map

 

And now I get no error more

 

I hope I've done it now, so yes, I want to thank you all very much for the thing I've learned again through AVSIM :-)

Now you have to check which weather is use in PFPX because it may be different from the one used by FSX.

 

Be aware that even if you select real weather in PFPX and real weather in fsx, as the source of the weather may be different, the weather you experience in fsx may also be different from the one used for the flight planning and the QNH may also be different.

 

Check the ATIS in fsx to get the actual QNH in fsx. Don't use blindly the one given by PFPX!

 

I would also advise you to go for a weather injection software for more realism. There are several out there like active sky next ASN (which by the way would allow you use the weather radar) or OPUS weather.
