Since it's not 1940, I doubt many in aviation will even notice. :mrgreen:

The only time I do is if ATC asks me to fly a heading. I'll still do it the same way no matter what the Earth's core is doing, so *shrug*. If my heading is not what ATC expects, they will give me a new heading to fly!

Compass? What's that? Oh, do you mean that magenta line on my GPS? :mrgreen:

My SportCruiser didn't even come with a whisky compass, just the remote magnetometer from Dynon.

Oh I do proudly own a whisky compass - it is somewhat hidden, right behind my handsome go-to rug for spilled liquids in the cockpit ...

I'm actually glad to have both a whiskey compass and the Dynon; I have never really been able to calibrate my Dynon magnetometer to be correct, no method I have tried has left it closer to true than 3-5° or so. As a result, when asked to fly a heading I refer to Mr. Whiskey.

Glad you all saw the humor in this. That article makes it sound like the world may be ending! Anyway, here in PugetSoundLand, our variation is something like 18-20 degrees westerly, so the Boy Scout compass is kind of a crap-shoot. Fortunately, in the 4 different Skycatchers I've flown, the HSI was very reliable, but the GPS still wins, hands down. Failing this, there is always IFR (I Follow Roads).
