September 27, 2025Sep 27 Hi Nico, I have a QNH discrepancy. PSXT is showing a QNH of 1014 instead of 1025 for Mexico City Intl. Airport (MMMX). RealTraffic METAR shows the correct QNH, according the the current METAR, 30.27 this is 1025 hpa. This issue makes the aircraft land a lot before the airport, as shown in the images. Thank you Jaime.

September 27, 2025Sep 27 Hi, PSXT gets its QNH from the RT server via a API. The RealTraffic app is not used. If you use the RealTraffic App with PSXtraffic you will probably see the right 1025 in PSXTraffic. Don't know why they differ, must be a hick-up.

Try it at another airport in another country and if you see the same thing, report it in the RT forum please. Edited September 28, 2025Sep 28 by kiek
