known issue Magnetic compass (repeater) incorrect declination

[Nealius]

Batumi, 2016, magnetic declination should be -6°. 

 

Control Test

A-10C. Infobar heading (true) 306° compass and HUD reading 300° as expected.

 

Mosquito Test

Infobar heading 306°. Expected compass reading 300°. Actual compass reading 275° which is 25° more than correct declination.

Was this taken while idling on the ground? I noticed that you need to throttle up quite a bit for the repeater and the DI to align.

 

On a sidenote, there is no magnetic deviation on the Channel map, but I think ED is aware of this.

What about the normal compass infront of the throttle lever? Does it show the same deviation?

 1200rpm. Should I be testing in-flight?

I'm unsure if I aligned the main compass correctly or am reading it correctly, but it is reading 295° which is still incorrect declination. This time the repeater was reading 291°.

Which begs the question: Why does every warbird except the Jug give 10° (or more) of declination on the Channel map?

Yeah, well, compasses are a bit of a mess in DCS at this moment, very inconsistent. This is one of the main blockers of my Mossie campaign. I don't want to record 100s of voice overs with headings only to change it later when it's fixed.

 

In any case, all compasses should point at infobar + 10 degrees over the Channel map. See Manston runway, that's your magnetic heading.
