IvanK Posted January 12, 2009 Posted January 12, 2009 I don't think BS uses Mag variation at all, regardless of what the manual implies. So far twisting the variation knob has no effect on any heading reference display in the cockpit. In addition in the ABRIS settings you can set the ABRIS reference to True or Mag. I have done this whilst sitting on the ground and the ABRIS track display (i.e the numbers) remains the same. All that changes is the letter next to the displayed track from M to T. In addition the track displayed by the ABRIS agrees exactly with the heading displayed in the HUD, HSI and stby compass. Based on this I suspect that the only heading reference used by BS is in fact True .... this goes for the Stby compass as well. The alternative is that the in game Magnetic variation is in fact 0 though in the Kuban region it should be around 5.5 deg East. If Magvar worked then the ABRIS Magnetic track should always be 5.5degrees less than the ABRIS True track.
