hmm, thanks but that still leaves me wondering. How do I know which data is used when I'm sitting on my runway? Could be the chart uses recent 2010 data while the sim, for this particular section of the world, uses 1995 data. An what about changing MV by a mere 0.6deg resulting in a 2deg heading difference? Or was it just me and my lazy eye?

Hi all, I was sitting on Senaki 09 the other night having a look at the airport charts by vJaBoG32. The heading of the runway was bang-on 90deg according to the HSI. But the chart said it should be more like 88deg. The magnetic variation stated in the chart was E6deg with a 2010 written in brackets underneath it, which I assume means "data from 2010". That got me thinking how current is the magnetic variation data in this sim? The MV value in the CDU was set to E6.2, which gave me 90deg. I had to set it to E6.8 to get the 88deg stated in the chart. Does that make sense? If i want a difference of two degrees I should have to change the MV by two degrees, right? Could it be that the difference in heading in the game and on the chart is due to the game data being more recent?
