3.3.2 Vertical bearing mark, tilt mark
The vertical bearing mark is displayed with solid and dashed lines and it shows
the bearing selected on the horizontal display. The circle at the top of the vertical
bearing mark has a “V” inside of it in the vertical 1 mode, or “1” and “2” as
appropriate when both the vertical 1 and vertical 2 modes are active. Its bearing
may be referenced to North (true) or ship’s heading (relative, default setting) on
the menu.
The tilt mark is a solid and dashed line which shows in the vertical display the tilt
angle set on the horizontal display.
The meaning of the solid and dashed lines are as shown in the table below.
