I was loading my FS9 at Seattle and on the default Cessna I noticed the compass and DG heading on the Runway 34R showed 360. The actual heading of course is 340. Am I indicating true headings not magnetic and if so how do I change it? :(

Did you add any scenery recently? This topic has come up in the past, and this problem is usually traced back to a FS-2002 scenery file being used in FS-2004.Try disabling any third party scenery you may have, and then adding it back, one at a time, until you find the culprit. Sometimes the offending file is literally on the other side of the planet from where you experienced the compass problem.Todd

Thanks Todd, I have added many scenery files lately so it could be the cause. I have since re-installed FS9 at this time the headings are OK but time will tell. The idea of de-installing and then re-installing scenery seems rather daunting!Rob
