Q

You take a bearing of 176° of a lighthouse. What bearing of another object would give the best fix?

🔍 Key Concepts

• Cross bearings and why large angles give a more accurate fix • The idea of bearings that are nearly at right angles (about 90° apart) • How small intersection angles between lines of position affect fix quality

💭 Think About

• Compare each choice to 176° and think: which one gives a line of position that crosses my first bearing at close to a right angle? • Ask yourself: when two bearings are nearly in the same direction, what does the intersection of those lines of position look like on the chart? • Which choice is most different in direction from 176°, not just by a few degrees, but by a large angle?

✅ Before You Answer

• Calculate the angular difference between 176° and each option (always use the smaller angle between the two directions, max 180°). • Look for the bearing that makes the largest angle with 176°, ideally near 90°. • Eliminate any option that is almost in line with 176° (same or opposite direction), since that gives a poor fix.
