Aha,I was wondering what this thread was about. I guess it is a
matter if definition. The basic definition of a magnetometer as I
understand it is to detect and measure magnetic fields. None of the
magnetometers I have used were small enough, light enough or logically
located in a cockpit. Then again none were connected to a computer.
