HOW TO MEASURE BEARINGS

First of all, take a look at this video below




Are you clear? Need more?

Let's us find out more information about bearings...

The true bearing to a point is the angle measured in degrees in a clockwise direction from the north line. We will refer to the true bearing simply as the bearing.

For example, the bearing of point P is 065º which is the number of degrees in the angle measured in a clockwise direction from the north line to the line joining the center of the compass at O with the point P (i.e. OP).

The bearing of point Q is 300º which is the number of degrees in the angle measured in a clockwise direction from the north line to the line joining the centre of the compass at O with the point Q (i.e. OQ).

Note:

The bearing of a point is the number of degrees in the angle measured in a clockwise direction from the north line to the line joining the center of the compass with the point.

A bearing is used to represent the direction of one point relative to another point.

For example, the bearing of A from B is 065º. The bearing of B from A is 245º.

Note:

• Three figures are used to give bearings.
• All bearings are measured in a horizontal plane.

Use of BeARing...

Determining a position

A bearing can be taken relative to a charted or mapped object at a specific time. This bearing can be used to determine the position of the vessel or landmark when used in conjunction additional bearing(s) or other information (e.g. depth, declination, etc.).

However, a pre-calculated bearing to a charted object can be also be used as a precautionary measure. For instance, if anchored in a harbor with a shore to the north, it can be decided that the vessel must stay to the south of an object to its east. If it does not, an anchor watch must inform someone to take action. Or, if moving through a channel with obstructions to the west and which is not well-marked with buoys, it can be decided that the vessel might have to stay to east of a particular charted object. Similarly, a land navigator might walk a bearing several degrees to the east of his actual course to avoid difficult ground, or to intercept an intersecting position (such as a road or trail) leading to his/her destination.[8] Upon reaching the road, the navigator simply turns west to ensure he will reach the destination.




Piloting

A bearing can be taken on another vessel to aid piloting. If the two vessels are travelling toward each other and the relative bearing remains the same over time, there is likelihood of collision and action needs to be taken by one or both vessels to prevent this.







Warfare

A bearing can be taken to a fixed or moving object in order to target it with gunfire or missiles.



Search and rescue

A bearing can be taken to a person or vessel in distress in order to go to their aid or, when that is not possible, to report the person or vessel to authorities or someone who can go to their aid.

BeaRiNg....

In marine navigation, a bearing is the direction of one object in relation to another object, the other object usually being one's own vessel.

In aircraft navigation, a bearing is the actual (corrected) compass direction of the forward course of the aircraft.

In land navigation, a bearing is the angle between a line connecting two points and a north-south line, or meridian.

ComPAss DireCtioNs

there are 8 main compass directions which are

• N = north
  
• E = east
  
• S = south
  
• W = west
  
• NE = north-east
• SE = south-east
  
• SW = south-west
  
• NW = north-west

WHEN DO YOU USE THE COMPASS??

• A compass is of utmost importance when travelling outdoors.

• When combined with a map it can help lead you to safety, whether the weather conditions are poor and the correct route is not visible, or for times when you are simply unsure.

• People who venture out into the mountains without a compass are doomed, and their trip will almost certainly end in casualty, or worse, fatality.
