USCG Exam PracticeRunning fix from a single object
A line of position (LOP) obtained from a single bearing observation tells the navigator that the vessel is located:
- A. At the exact point where the bearing line crosses the DR track
- ✓ Somewhere along that bearing line at the time of observationCorrect
- C. At the fix derived from the intersection of two simultaneous LOPs
- D. At the advanced position of the first LOP along the DR track
Why B is correct
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 fix; it only constrains the vessel's position to that line. Bowditch Ch. 7 §701.
