USCG Exam PracticeRunning fix from a single object
When plotting a running fix from a single object, what action is taken with the first line of position?
- A. It is discarded and only the second bearing is used to establish position.
- B. It is averaged with the second LOP to reduce bearing error.
- ✓ It is advanced along the DR track by the distance run between the two observations.Correct
- D. It is held in place and the second LOP is retarded back to the time of the first bearing.
Why C is correct
Per Bowditch Ch. 7 §708, the first LOP is advanced along the DR track by the distance run on a steady course, then laid across the second bearing; their intersection is the running fix.
