USCG Exam Practice · Visual piloting — three-bearing fixes, danger bearings
A fix is best described as which of the following?
- AA single bearing to a charted object taken at a known time
- BThe intersection of two or more lines of position taken simultaneously✓ correct
- CA dead reckoning position advanced from a known departure point
- DA position obtained by advancing one LOP along the DR track to a second observation
Why B is correct
A fix is the intersection of two or more LOPs taken simultaneously. A single bearing is only one LOP; advancing an LOP along the DR track produces a running fix, not a fix. Bowditch Ch. 7 §701.
