Question 1820Navigation General70% to pass

You take a bearing of 356° of a lighthouse. Which bearing of another object would give the best fix?

AI Explanation
The correct answer is C) 256°. To obtain the best fix from a bearing of 356°, you would want to take a second bearing that is as close to perpendicular (90°) to the first bearing as possible. The bearing that is perpendicular to 356° is 086°, and the bearing that is closest to this is 256°. The other options are not optimal because they do not provide a bearing that is close to perpendicular to the original 356° bearing. A bearing of 013° would be too acute, 178° would be too parallel, and 342° would also be too acute.
