USCG Exam PracticeEstimated position from current set & drift
How is the course line labeled on a standard DR plot?
- A. True course above the line and speed below the line, both in 24-hour format
- ✓ True course above the line labeled as 'C' followed by the three-digit course, and speed below labeled as 'S' followed by the speedCorrect
- C. Magnetic course above the line and distance run below the line
- D. Speed above the line labeled as 'S' and true course below the line labeled as 'C'
Why B is correct
Bowditch Ch. 8 §802 specifies that the course line carries the true course above it in the form 'C 090' and the speed below it in the form 'S 8'. Magnetic course is not used on the DR plot label, and the positions — not the line — carry the 24-hour time.
