Bearing. A bearing is the direction from your location to any distant point given in degrees from north. If you point your compass at a distant lighthouse and the compass reads 56 degrees, then the bearing to the lighthouse is 56 degrees. Read bearings in either true or magnetic.Dec 6, 2010

AnswerHow do you find the bearing of a point?
We haven't quite finished yet and it is very easy to give our final answer as 028 degrees to the nearest degree but we still need to work out the bearing of B from A measured from North. We must add out new value for alpha to our original bearing 042 degrees. Don't forget the final bearing needs to be written using 3 figures.

How do you find the bearing of an object?
Relative bearing refers to the angle between the craft's forward direction and the location of another object. For example, an object relative bearing of 0 degrees would be dead ahead; an object relative bearing 180 degrees would be behind. Bearings can be measured in mils, points or degrees.

How is course similar to bearing?
Course. Course is very similar to bearing in that it’s the desired direction for your route of flight. If you are going directly from one airport to the other, your course and bearing will be the same along the route of flight. If you are flying from an airport to a VOR to another airport, your course will change in each leg, as will your bearing.
Why is bearing confusing?
Bearing can be confusing sometimes because has some overlap with course. Bearing is simply the angle or direction between two points. A practical application of this is in VOR navigation. It’s a common thing to hear someone say “we are bearing 090 from the station”.
What is the difference between a track and a heading?
Heading is the direction the airplane is pointed, whereas track is the actual direction of the airplane tracking across the ground. Bearing is the angle between any two points, whereas course is your intended path of travel to your destination. In the rest of this post we’ll elaborate on each of these points and then also provide ...
What is heading in airplanes?
This does not factor for wind, or the actual movement of the airplane across the ground. It only refers to what the compass reads based on where the nose is pointed.
Background
The world's navies have long practiced Target Motion Analysis (TMA), which is a process for determining the position, course, and speed of a target using passive sensor information (i.e. bearings with no range information).
Analysis
For those who want to follow along with my Mathcad work, here is my worksheet.
Conclusion
I was able to duplicate the work done in Spiess' original work and develop a Mathcad model that I can use for preparing some personal training scenarios. Overall, this was a good exercise.
What is bearing angle?
Bearing or heading angle is used to define navigation generally in the field of aircraft or marine or Vehicle navigation or while working for land surveying.
What is the difference between bearing and heading?
While Heading is an angle or direction where you are currently navigating in.
What is a compass for navigation?
Generally a ‘compass’ is an instrument, which gives you the direction information for navigation . You must refer Haversine distance formula before going through this post.
What direction do winds blow?
Winds are named according to the direction from which they are blowing. For instance, a westerly wind blows from the west (or 27 0°), while a southeasterly wind blows from the southeast (135°).
What is the direction of an azimuth?
An azimuth is the direction measured in degrees clockwise from north on an azimuth circle. An azimuth circle consists of 360 degrees. Ninety degrees corresponds to east, 180 degrees is south, 270 degrees is west, and 360 degrees and 0 degrees mark north. The word "bearing" is sometimes used interchangeably with azimuth to mean the direction ...
What is azimuth in wind?
Azimuth is often used to denote wind direction. Traditionally, wind direction is reported as one of eight compass point (N, NE, E, SE, S, SW, W, NW). However, plots of wind and speed direction often give an azimuth value using 0° and 360° for north, as described above. Winds are named according to the direction from which they are blowing. For instance, a westerly wind blows from the west (or 270°), while a southeasterly wind blows from the southeast (135°).
Heading
Heading is probably the most confusing term out of all of these because it can most easily be used in conversation to replace track, bearing, or course. By definition though, heading is actually just the direction that the nose is pointed. This does not factor for wind, or the actual movement of the airplane across the g…
Track
- Track is the easiest of these four to understand in my mind,because it simply refers to how you are actually tracking over the ground. Whennavigating in the air, your track is really all that matters in terms ofgetting to where you want to go. If you need to go northeast to yourdestination, and have a significant wind from the west, your heading might beto the north in order to achieve a tr…
Bearing
- Bearing can be confusing sometimes because has some overlap with course. Bearing is simply the angle or direction between two points. A practical application of this is in VOR navigation. It’s a common thing to hear someone say “we are bearing 090 from the station”. This simply means that off of the VOR they are tracking on the 090 radial outbound from the station. In relation to th…
Course
- Course is very similar to bearing in that it’s the desireddirection for your route of flight. If you are going directly from one airportto the other, your course and bearing will be the same along the route of flight.If you are flying from an airport to a VOR to another airport, your course willchange in each leg, as will your bearing.
Example
- For this example we’re going to work backwards through the above mentioned directions. Assume you are departing an airport and your destination is directly eastbound. When you take off the course between the departing airport and destination airport is 090. In this instance the bearing of the destination airport off of your departing airport is also 090. This is also the direction you wan…
Does A GPS Use True Or Magnetic Heading?
- The above example assumes you are using the compass in yourairplane (hence why it requires so many steps to calibrate the differencebetween your true course all the way down to your actual compass heading). Butwhat about a GPS? By definition it’s not using earth’s magnetic fields as a wayof navigation, but rather positioning information provided by satellites. So ifit shows your “de…
