Dear Captain7, thank you for looking into this. I have about 400+ hours in the 744 level D simulator and am very familiar with EDDN in the real world with models like the TBM 850 and PC12. You have built an amazing replica of that airport. PMDG is true to 99+ percent of the real thing. As far I can see, Navigraph is also confused, and on all aircraft with systems like Primus Apex and the newer Boeings you can't override the frequencies as they are part of your filed flight plan. I've shared this with great friends who fly 744s and 748s for a major European cargo airline, and they could not resolve it either. But thanks very much for your congenial effort.
Great work, 29Palms
