Bearings

• Bearings are a way of describing and using directions as angles

• They are specifically defined for use in navigation because they give a precise location and/or direction

How are Bearings Defined?

• There are three rules which must be followed every time a bearing is defined

  • They are measured from the North direction

    • An arrow showing the North line should be included on the diagram

  • They are measured clockwise

  • The angle is always written in 3 figures

    • If the angle is less than 100° the first digit will be a zero
