USCG Exam PracticeThree-bearing fix and cocked-hat triangle
A line of position (LOP) derived from a single bearing observation tells the navigator that the vessel:
- ✓ Lies somewhere along that line at the moment of observationCorrect
- B. Is located at the exact point where the bearing crosses the DR track
- C. Has a confirmed fix that requires no additional observations
- D. Is at the charted object from which the bearing was taken
Why A is correct
A single LOP establishes only that the vessel lies somewhere along that line at the time of observation. A fix requires the intersection of two or more LOPs taken simultaneously. (Bowditch Ch. 7 §701)
