Bearings/navigation

  1. Understanding Bearings

    • Bearings are a way to measure the direction of an angle, typically used in navigation and cartography.

    • They are expressed in degrees from north (0°) in a clockwise direction.

  2. Basic Rules

    • Bearings are written in three figures (e.g., 045°, 230°, 312°).

    • The first figure denotes the direction from North (0°) or South (180°).

    • Bearings should always be measured in a clockwise direction.

  3. Converting Between Bearings

    • To convert from a compass direction to a bearing, identify the angle from North or South.

    • For example, East (E) corresponds to 090°, West (W) to 270°.

    • To find the bearing of angle A from point B, measure the angle from the North in a clockwise direction.

  4. Calculating Bearings

    • Bearings can be calculated using triangulation methods or directional movement along a chart.

    • Use adjacent angles to determine the relative bearings between two points.

    • Always verify calculations by checking against known points or visual landmarks.
