Section 5Step by Step

To plot a course line from a departure point: Correct the course from compass to magnetic to true, if necessary. Use the plotter to draw the line. Label the departure point as a fix and the line with course and speed, using the plotting conventions. |
Plot a DR position every hour on the hour or with every change of course or speed. Use the 60D=ST formula to determine distance traveled. |
Transfer distance from the latitude scale to the plotted course, using dividers. |
Label the position with the DR symbol () and time of the position (at an angle). |
