Question

How do calculate compass bearing for point A To B

Answer 1

Each map has North on it and grid lines that also show North, East, South, West.

If you want to travel from A to B:

1. Align the edge of your compass along the line that connects A and B.
2. Turn the bearing so that it points toward North parallel to the grid lines. Name this angle $\alpha.$
3. Add magnetic variation $\nu$ if applicable.
4. Hand your compass before you and turn your body for angle $\tau$ until the magnetic needle with N on the arrow is aligned with the arrow that is drawn in the bearing.
5. There you go.

How to calculate compass bearing:

$$B=\alpha+\nu+\tau.$$
