Some properties of the curve of constant bearing

If Z is a fixed point on the surface of the earth (assumed spherical) and P is the North Pole, then the locus of a point X , which moves in such a way that the angle α between the great circle arcs PX, ZX is constant, is called a curve of constant bearing .
