To clarify the whole behavior of turning errors of the magnetic compass, many turns are conducted from various courses by the trainers of Civil Aviation College. In turning to the right, the maximal lag error of the compass occurs between the heading of 10° and 40°, and the maximal lead error occurs between the heading of 130° and 160°. The extent of the maximal error depends upon the angle of aircraft bank. An angle of bank has the greatest effect on compass errors among the flight characteristics of an aircraft. The effect of flying speed, the time rate of bank and flying altitude are investigated. The results of flight experiments quite agree with those of computing errors through Lindemann's procedure. As a result of the studies, turning error curve is proposed. The computed turning error curves to one angle of bank are almost the same for the compasses used today. This curve can be applied to any turning by using the magnetic compass.
