USCG Exam PracticeThree-bearing fix and cocked-hat triangle
To obtain the strongest possible visual fix from three charted objects, the lines of position should ideally cross at approximately:
- A. 30 degrees to each other
- B. 45 degrees to each other
- C. 60 degrees to each other
- ✓ 90 degrees to each otherCorrect
Why D is correct
Bowditch Ch. 7 §707 states that the strongest fixes cross their LOPs near 90 degrees. Shallow crossing angles magnify small bearing errors into large position errors.
