Hi there,This is my first post. I have been flying FS9 for years and have never encountered this issue. When i am lined up with the runway i set my heading indicator to match the magnetic hdg of the rwy. The only problem is its 20 degrees off. So for example at SEA i will line up on 34r and the rwy will be 20 to the left on the fms. This is with any plane I use, PMDG, Wilco, LDS ect. Whe I am flying i am aslo 20 degrees off of the airway. I dont know what happened to cause this. I have downloaded the latest ariac(711) but nothing seems to work. Any feedback would be great.thanks,will
