Figure 9: Course-Up Chart Orientation - NorthStar 961 Reference Manual

Chapter 13 - Customizing Setup Functions
Page 13-32
When a course-up orientation is chosen (see Figure 9 below),
the chart rotates to match the actual southeasterly trip leg that
the vessel is still navigating on as it travels to the GREATVIEW
waypoint. The north-pointing arrow in the upper right corner
shows that north is now at the bottom of the chart.
If you now change the chart's orientation to leg-up while on this
southeasterly leg, the orientation of the chart is similar to course-up.
However, in leg-up mode, if you enter yet another leg going in yet
another direction, the chart is automatically rotated, immediately
upon sequencing to that next leg, even if you haven't turned the
vessel yet.
To set the chart-orientation option:
1. At the CHART SETUP screen, press the CURSOR PAD to
highlight the CHART ORIENTATION option, then press
the EDIT key.
2. Press the CURSOR PAD left or right to select the desired
value, then press the ACCEPT key (or press CANCEL to
leave the value unchanged). When you return to the
CHART screen, the new orientation is displayed on both
View A and B.
