yep, Ivan is right, when calibrating your gyro compass, you have to add around 10(.5, roundabout) deg. to your magnetic compass bearing. This was not yet implemented at CoD launch, but was fixed in a patch and mentioned in luthier's patchnotes.
Try that, you should achieve better results then.

P.S.: The explanation for this is that the headings on maps are 'calibrated' with respect to the earth's true north/south poles, i.e. the geographic poles, around which the earth rotates. The magnetic compass obivously measures geomagnetic north, wich is off by the mentioned value in the UK/France area.

hmm any updates regarding the waypoint feature? How to best use them/delete them?
I figure it would be quite handy to use them as you can mark flak, ships, vehicles ect, too.

When flying PF we printed out maps and prepared in forehand. That was vital if you wanted to have a chance to return to Essex.

In CloD, like already stated, the map is so small and landmarks everywhere so I can't see any use for advanced navigation.
We don't have bad weather nor overcast so IR is of no use.
Even if we had bad weather air missions at that time was never executed unless good conditions.

Sure, advanced navigation is fun but for now useless imo.

Redroach, can you confirm this please:
'...when calibrating your gyro compass, you have to add around 10(.5, roundabout) deg. to your magnetic compass bearing...'

I thought the procedure was to add/subtract variation to the TRUE bearing to get the Magnetic reading, and then add aircraft deviation to MAG bearing to get the correct gyro compass bearing. I assume deviation isn't modelled. So in this case we should add 10 deg to TRUE not to Magnetic reading. I'm no expert, please correct me if I'm wrong. Regards....

I guess you're the same freak just like me who recognizes true missions only if they start and end on a runway/an airfield

All headings measured on the map are true. So you need to add 10 degrees to obtain the magnetic heading to fly both on line or off line. Your dg can be aligned on any refrence true or magnetic. However since the only refrence you have in the cockpit is the magnetic compass the convention is to align the dg to a magnetic refrence.

So measure in true convert to magnetic, set dg refrence magnetic heading and fly magnetic.

why not just substract 10 deg on your course heading indicator thingy (at least for the RAF, which have such an instrument) and go for true north directions?

Because the ONLY heading refrence you have in the cockpit (the compass) is magnetic. Because the dg is subject to gyro drift/precession it needs ro be reset or synched regularly.
The only refrence you have in the cockpit to refrence and synch with is magnetic. Hence magnetic is always used.

Modern nav systems (inertial/gps etc)
can use any refrence however the normal convention is still to use magnetic.

Yes, I understand, but still, all you need is to always remember: "minus 10 deg" when setting, or re-setting the gyro. It's no additional work when resetting or resynching.
Then, you can just *read* the map, without any further calculations.

Again, I understand that convention is magnetic, because the magnetic compass is "always right" (within its 10° error). However, I might deviate from original protocol in this one case
