Question 1824Navigation General
70% to passYou take a bearing of 142° and 259° of two objects. What bearing of a third object will give the best fix? -
A
281°
B
084°
C
019°
D
166°
AI Explanation
The correct answer is C) 019°. The reasoning behind this is that to obtain the best fix, the third bearing should be taken at a 90-degree angle (or as close to it as possible) from the first two bearings. This is because the intersection of the three bearings at a 90-degree angle will result in the most accurate and reliable fix. The bearings of 142° and 259° are approximately 117 degrees apart. To get a 90-degree angle, the third bearing should be 019°, which is about 90 degrees from the first two bearings. The other options are incorrect because they do not provide a 90-degree angle from the initial two bearings.
