USCG Exam PracticeVisual piloting — three-bearing fixes, danger bearings
A line of position (LOP) derived from a single bearing observation tells the navigator that the vessel is located:
- A. At the exact point where the bearing line crosses the chart datum
- ✓ Somewhere along that bearing line at the time of observationCorrect
- C. At the intersection of that bearing with the vessel's DR track
- D. Within a circle of uncertainty centered on the observed object
Why B is correct
By definition, an LOP is a line along which the vessel is known to lie at a given moment based on a single observation. A single LOP does not produce a point fix; it only constrains the vessel to that line. Bowditch Ch. 7 §701.
