Magnetic Variation on Kneeboard.

[IronChancellor]

I asked this before in the Mi-8 fourm, but could we get the mag var on the kneeboard like the F14 has?

[Volator]

Knowing the mag var for a certain map/time frame is very important. I'd rather like to see this information on the F10 map, but on the kneeboard would be fine too.

[FlankerKiller]

Or both, but it definitely needs to be there.

I think F10 map isogonic lines layer would be a good solution that takes care of every module all at once, like:

Maybe every 0.25 or 0.50 degree would be lots of density. Usually sectional charts are every half degree. I don't know if there's an easy way to turn the variation data/equation into such lines. I guess they could be pre-calculated for the mission date and a semi-static layer.
