Runway heading in runway.xml not correct

[roa]

Hi,

 

I get a difference in heading for all runways between the runways.xml from Makerunway.exe and the Jeppesen chart.

Why is it so? I have P3Dv4 updated .

 

 Jeppesen chart says runway 10 heading is 098 degree, but runways.xml says  101.060.

Hi,

the Jeppesen chart you use might be uptodate where MakeRwys reads the used data in FSX/P3D and they are mostly very old. So the MagVar is out of date and Depending on location it can be couple degree.

Thanks for you replay.

I got it now.

I checked the MagVar in the runwys.xml for the exapmle airport EIDW and it says 2.980. Taken that into account the heading should be correct.
