codefox Posted January 24, 2016 Posted January 24, 2016 The heading on both the HUD and the HSI is off by five degrees, as you can see on these two screenshots. First screenshot - heading on HUD and HSI is 040 Second screenshot - true heading is 046 This has been reproducable since the first version of the Mirage came out. [sIGPIC][/sIGPIC]
PiedDroit Posted January 24, 2016 Posted January 24, 2016 This wouldn't be a bug if magnetic declination is implemented in DCS. Magnetic declination is 6° in Georgia, so 40° magnetic heading correctly translates to 46° true heading. Instruments are suposed to show magnetic heading, unless you select Cv (Cap Vrai = True Heading) on the HSI.
codefox Posted January 24, 2016 Author Posted January 24, 2016 You are correct. I just pressed the HSI mode select button and it switched to true heading. Hence, no bug and this report can be dismissed. :) [sIGPIC][/sIGPIC]

PiedDroit Posted January 24, 2016 Posted January 24, 2016 (edited) Just learned about declination in my SAR nav course Yeah it's interesting topic. Here in Montreal the declination is -14.5°, nasty ;) Also, not to be confused with magnetic deviation which is the magnetic influence of the own ship, which is (I think it should be) compensated by the instruments so you don't have to worry about it :smartass: Edited January 24, 2016 by PiedDroit
