USCG Exam PracticeVisual piloting — three-bearing fixes, danger bearings
A line of position (LOP) derived from a single bearing observation tells you that your vessel:
- ✓ lies somewhere along that line at the time of observationCorrect
- B. is at the exact point where the bearing crosses the chart
- C. has a confirmed fix requiring no additional observations
- D. is on a collision course with the observed object
Why A 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 fix requires the intersection of two or more LOPs taken simultaneously. A single LOP does not constitute a fix.
