USCG Exam PracticeRunning fix from a single object
You are plotting a running fix and wish to apply an estimated position correction afterward. Which of the following correctly describes the estimated position (EP)?
- A. The DR position advanced along the DR track to the time of the second bearing
- ✓ The DR position corrected for estimated set and drift of the currentCorrect
- C. The intersection of two simultaneously observed LOPs
- D. The DR position corrected for compass error and leeway only
Why B is correct
The EP is the DR position corrected for the estimated set and drift of the current, plotted as a dot inside a square. It is the best position available between fixes when only the current can be estimated. (Bowditch Ch. 8 §803)
