There is a good reason. An adjustable compass like that would be much more prone to user-error. Someone may rotate it too much causing very large discrepancies and land on the wrong runway.
- dnadler 8y agoSame can be said of altimeter adjustments which would literally cause you to fly into the ground, but that isn't stopping us from allowing manual adjustments.
- aeternus 8y agoBarometric pressure can fluctuate every day, and by relatively large amounts causing errors of 500ft+ so there, the 'price' of manual adjustment is worth the gain in accuracy. I'm not convinced the same can be said for magnetic adjustment.
