List of Figures

  1. Relation of True and Magnetic headings
  2. Northerly turning error
  3. Northerly turning error graph
  4. Contours of max lead/lag
  5. Compass heading vs. magnetic heading for two bank angles in a right 360 turn
  6. Compass response to airspeed changes on an East heading
  7. Compass error vs. magnetic heading while accelerating

Figures 1, 2 and 6 are taken from the FAA's ``Instrument Flying Handbook'', (AC 61.27C) which has good material on this subject. Note that the new FAA-H-8083-15 has some bogus information on ``dip compensating weights'', which are not used in standard aviation compasses.
