In navigation, the course of a watercraft or aircraft is the cardinal direction in which the craft is to be steered. The course is to be distinguished from the heading, which is the direction where the watercraft's bow or the aircraft's nose is pointed.[1][2][3][page needed] The path that a vessel follows is called a track or, in the case of aircraft, ground track (also known as course made good or course over the ground).[1] The intended track is a route.
