Hello Captains,During my last flights with the Queen, I noticed a thing, I cannot find an explanation for.Reading the wind data from the FMC's PROG side the wind is for example 256/17. In the map display, there is in most cases a difference from 5 or 6 degrees. So here the wind is shown with 251 or 252/17. Does anybodey know the reason for this ?I am using a non pirated version of FSUIPC (newest) and ASV.

I believe it has to do with magnetic variation. If i don't mistake, on the ND you have winds magnetic, while on the progress page they are true.Regards,Bjorn

Hi Bjorn,yes, you may be right. At least this is an explanation I can "live with".Thank You
