Worked Example 1: Simple Back Bearing
The bearing of B from A is 065°. What is the bearing of A from B?
Step 1 Identify if bearing < or > 180°
065° is less than 180°
Step 2 Add 180° for back bearing
Back bearing = 065° + 180° = 245°
Practice questions for Bearings
A ship travels in the direction of North-East. Which of the following correctly writes this as a three-figure bearing?
Explain how to find the back bearing (return bearing) of any given bearing. Your answer should cover both cases.
