Anyway like in real life remember to correct your directional gyro after vast and rapid changes in altitude, heavy aerobatics or g-loads, eventually every every 15min.

Totally agree - What a brilliant sim. I started my flying career in a DeHaviland Chipmunk and that had the same compass - Actually it was like the Blenheim with a T shaped double lines on the bezel. It was in the same place as the Spit and hurricane, it was hard to see or to reach the bezel and adjust it while trying to fly straight - essential if you want it to read correctly. I think the Altimeter lags a bit in descent. The DI definately drifts in Hi-G manoeuvres.

Okay - Anyone know if Variation is in the Sim and when we put the Grid in missions, is it aligned with True North?

All in all a BRILLIANT Sim.

Magnetic declination in the sim is 10 degrees West.

Unsure if the grids are aligned with this or not.

Outstanding, Thanks. That sounds about right. Its about 2 degree west now and was about 4 degrees west when I started flying 25 years ago so 10W adds up.

Grids point to Grid North. So any angles measured then need to be adjusted for 10W variation.
(Add 10 degrees) to get Mag.

Thanks, but are you sure you meant to say that.

I think you meant - Grids point to True North. Otherwise, your next sentance does not make sense.
