Question 1817Navigation General

70% to pass

You take a bearing of 264° of a lighthouse. What bearing of another object would give the best fix?

A 120°
B 081°
C 289°
D 350°
AI Explanation

The correct answer is D) 350°. To get the best fix, you want to take a bearing that is perpendicular, or as close to perpendicular as possible, to the first bearing of 264°. This is because perpendicular bearings provide the greatest triangulation and intersect at the sharpest angle, giving you the most accurate position fix. The bearing that is perpendicular to 264° is 354°, so 350° is the closest option provided. The other options, such as 120°, 081°, and 289°, would not provide as strong of a fix since they are not as close to perpendicular.
