Of course, but we are still flying regardless, because we have to. The issues still happen after we have calibrated, but perhaps we haven't done it well enough. I want to make clear that we also have the all-life ending "compass error" as well.
Maybe, but compass errors usually have nothing to do with encountering any magnetic anomalies in the landscape, this is a very common misconception. The single greatest cause of compass errors is launching the aircraft from a surface that contains ferrous material. Of these, concrete containing rebar is the most common, but another is taking off from the roof of a vehicle, or the bed of a truck, or even powering the aircraft up while it is in a car. Look to these before you look elsewhere. The cure is to move the aircraft elsewhere, not calibrate the compass.
