USCG Exam PracticeRunning fix from a single object
A running fix is obtained by advancing the first LOP along which track to the time of the second observation?
- A. The estimated position track, corrected for set and drift
- ✓ The DR trackCorrect
- C. A line parallel to the danger bearing
- D. The reciprocal of the course steered
Why B is correct
The first LOP is advanced along the DR track to the time of the second observation; the intersection of the advanced LOP and the second LOP is the running fix. Bowditch Ch. 7 §702 and §708 both specify the DR track as the reference for advancing the LOP.
