Magnetic north, geographic north & map

[jf1981]

Hello,

I had troubles to follow a path, comparing the real compass in no-cokcpit view and the magnetic compass in the spit file, I see about 7-8 degree difference.

I realize that if you follow the magnetic compass, you end up having this degree of shift counter-clockwise.

Is thjis really taken in account ? That would be then the source of my calculation having led me to forest areas whereas I should have arrived at a destination airfield.

Thanks.
