November 18, 20223 yr  MSFS seems to show runway 12 at Missoula Montana( KMSO) , as do Navigraph/Jeppesen charts, but google maps and most airport diagrams appearing in LittleNavMap show 11 . Turns out they found a magnetic variation and repainted it from 11 to 12 around 2018 🙂 https://m-m.net/missoula-international-airport-runway-resealing-and-number-painting/#:~:text=Morrison-Maierle%2C on,accommodate the shift.  Using LNM with MSFS 2020 and currently the PMDG 737-700 on Windows PC
November 18, 20223 yr This happens from time to time in certain places. Because of the location of the magnetic north pole, and the direction it is drifting, the magnetic variation change year-to-year in the western US is much higher than in the eastern part of the country. That affects the actual magnetic heading of the runway, which is now closer to 120 degrees than to 110 degrees.

November 18, 20223 yr LNM shows it as 12 in my FSX installation. Perhaps it's due to Aero Sors updating it?
November 18, 20223 yr Runway numbers are stored separate from heading in the scenery library. LNM does not calculate them. Therefore, this is almost always an add-on issue. Sorry. Maybe an add-on not loaded from MSFS since it is encrypted? Alex Alex' Projects: Little Navmap
