Magdec.bgl

Will the Magdec.bgl file that contains the magnetic variation info for FS be updated in FSX. The Magdec.bgl file is used by scenery in FS to apply the correct magnetic variation to the true headings used in scenery design. I believe that this file has not been updated in a few versions of FS. Currently in FS9 for the UK, there is a 2 degree difference between the actual runway headings taken off charts and what appears in FS9. If you use real world charts and SIDs/STARs then you can be flying off the correct track/heading as a result of this anomaly. Thanks.

I happened to just download the new Lisbon scenery, and it is included in there.MAGVAR is included as an attribute in a number of elements, but I have never seen a description of what effect that actually has either on the user aircraft gauges or otherwise (such as VOR readings).scott s..
