USCG Exam PracticeThree-bearing fix and cocked-hat triangle
Which statement best describes a running fix?
- A. A fix obtained from two or more LOPs taken at exactly the same time
- ✓ A fix obtained by advancing an earlier LOP along the DR track to the time of a later observationCorrect
- C. A fix obtained by doubling the bow angle and measuring the run between bearings
- D. A fix obtained from radar range and bearing to a single target
Why B is correct
Bowditch Ch. 7 §702 defines a running fix as one obtained when LOPs cannot be taken simultaneously; the first LOP is advanced along the DR track to the time of the second observation, making it less accurate than a simultaneous fix.
