USCG Exam PracticePlot true course and distance between two charted points
A navigator plots a course line on a chart and labels it correctly. Which of the following represents the proper labeling convention for a course line?
- A. True course above the line labeled 'T'; speed below labeled 'KTS'
- ✓ Course labeled 'C' above the line; speed labeled 'S' below the lineCorrect
- C. Course labeled 'C' below the line; speed labeled 'S' above the line
- D. Course and speed both labeled above the line separated by a slash
Why B is correct
The standard convention is to label the course line with C (course) above and S (speed) below, for example 'C 090' above and 'S 8' below. This allows any watchstander to read the plot at a glance.
