    I have to ask: Why are airports still using magnetic compasses?

    Using magnetic north is a very good control. Location based N,S,E,W shoud only be used on certain maps. Complexes with main pathways and features askewed from magnetic N,S,E,W mostly. Contracter to new locations friendly.

    Not really sure how it applys to aviation though through and through.

    In the event of a worldwide war that knocks out GPS satellites it will be necessary to use this system. It's a national defense and emergency point. Kinda like if there is an extreme solar event that knocks out all of the positioning equipment and the satellites go askew.

    Why indeed? They KNOW where THEY are, right?

    The point was trying to show how ridiculous it is to insert arguments and attribute them to the other side when the other side isn't actually making that argument. It was in response to the "it's all man's fault crowd" comment. There are no environmentalists who propose that the earth's magnetic field is changing due to mankind's activities. (well, nobody who is sane or has the least bit of understanding of science anyway)

    My comments were not to be taken literally.

    The airport doesn't use the compass. Aircraft do. Runway numbers are based on the runway's approximate heading in relation to magnetic north. Magnetic north is used instead of true north because there's no way to reference and calibrate to true north in-flight. GPS has nothing to do with it, really.

    Longer answer: The gyroscope in the aircraft's heading indicator has to be calibrated to something. The pilot has no way of knowing where true north is, exactly. So every aircraft sets its heading indicator to what the magnetic compass says, this way they're all referencing the same thing. Since the aircraft's heading indicator now references magnetic north, the runways also reference magnetic north to make it easier for the pilot to correlate runway heading with his own. While GPS could technically reference true north just as easily as magnetic north, it wouldn't make sense for the pilot's heading indicator to not match the GPS, and not all aircraft are equipped with GPS anyway.
