 +
 +Deviation: caused by local magnetic fields within the aircraft. Deviation error is different on each heading
 +
 +Deviation card shows what the mechanics are unable to correct/​adjust.
 +
 +Magnetic Dip: indication errors caused by an unbalanced compass
 +
 +Teter-totter balance analogy--@magnetic equator north and south forces are balanced. Increase latitude, north pole is pulling down more than south pole.
 +
 +Above 60° latitude, compass is unusable—too much dip

 ===== Magnetic Compass Turns ===== ===== Magnetic Compass Turns =====
 +
 +When making a turn from a northerly heading, the compass briefly gives an indication of a turn in the opposite direction. When making a turn from the south, it gives an indication of a turn in the correct direction but at a faster rate.
