USCG Exam PracticeThree-bearing fix and cocked-hat triangle
Which statement best describes the recommended procedure for obtaining the strongest visual piloting fix?
- A. Take bearings to the closest objects first and work outward, crossing LOPs at 45 degrees
- ✓ Take bearings in quick succession, crossing LOPs near 90 degrees, with the beam-most object taken lastCorrect
- C. Advance the first LOP along the DR track before taking the second bearing
- D. Use a single charted object and apply the doubling-the-angle technique
Why B is correct
Bowditch Ch. 7 §707 specifies that the strongest fixes cross LOPs near 90 degrees, use positively identified objects, are observed in quick succession, and take the beam-most object last to minimize the effect of vessel movement during the observation sequence.
