I was having a hard time getting KTPA updated per the 1609 airac in FSC. For some reason, FSC showed the old runway headings. I eventually figured out that it was reading the addon scenery database in P3D and getting runway info from My Traffic Pro's facilities scenery. When I deactivated MT-Pro and ran the FSC database manager again, all the runways were in agreement with the new airac. Now, the FMC in the Quality Wings 757 has the same runways as FSC. So, my question is - Does anybody know how to update the scenery navdata in My Traffic Pro?
