Abstract: The solution presented here is based upon Napier's rules for solving right spherical triangles. Accuracy is dependent upon accuracy of construction. The use of a large vernier protractor will result in extreme accuracy. The Radar Plotting Sheet, used with care, will give results which are useable and not far less accurate than the spherical results normally used as compared with the spheroidal shape of the earth.
