[a] Any difference between the heading and course is due to the motion of the underlying medium, the air or water, or other effects like skidding or slipping. The difference is known as the drift, and can be determined by the wind triangle. At least seven ways to measure the heading of a vehicle have been described. [1]
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.
Great-circle navigation or orthodromic navigation (related to orthodromic course; from Ancient Greek ορθός (orthós) 'right angle' and δρόμος (drómos) 'path') is the practice of navigating a vessel (a ship or aircraft) along a great circle.
The pilot then adds these two to get 5° and flies 5° right of his previous heading. One can also use the 1 in 60 rule to approximate distance from a VOR , by flying 90 degrees to a radial and timing how long it takes to fly 10 degrees (the limit of the course deviation indicator ).
The navigator plots their 9 a.m. position, indicated by the triangle, and, using their course and speed, estimates their own position at 9:30 and 10 a.m. In navigation , dead reckoning is the process of calculating the current position of a moving object by using a previously determined position, or fix , and incorporating estimates of speed ...

In nautical navigation the relative bearing of an object is the clockwise angle from the heading of the vessel to a straight line drawn from the observation station on the vessel to the object. The relative bearing is measured with a pelorus or other optical and electronic aids to navigation such as a periscope, sonar system, and radar systems ...
