I installed the preview version. Very nice scenery. However, when I uninstalled it, The magnetic variation was 296 for RWY 28 and 029 for RWY 1. Could use some help to get this corrected. Oh Yes, No wind. But that would not matter when you are sitting in the RWY.
This should be fixed. It is not possible to navigate and fly an approach to any airport in the West with any precision with the magnetis variation so far off. Maybe the magnetic file was replaced with true. Just a guess.
After a long research, I found the scenery that caused the problem that changed the magnetic ver at SFO. It was NOT from Flightbeam. For me, the scenery was Tunisia file name (djerba2009version11). I installed it a few days before and did not notice the veriation. So all is well and I will purchase this SFO scenery.
