3 Navigation: Chart

The chart window shows the chart, the boat's position course and navigation data.

3-1 Overview of navigating

The 557/567 has two ways of navigating, going straight to a point or following a route.
3-1-1 Navigating to a point
When the 557/567 is navigating to a point, the
chart and highway windows show navigation
data:
A
A The boat position .
B The destination point marked with a circle.
C The boat's plotted course to the destination.
D Two CDI lines, parallel to the boat's plotted
course, which indicate the maximum
expected deviation from the plotted course.
For more information, see appendix C.
If the 557/567 is connected to an autopilot, the
557/567 will send data to the autopilot to steer
the boat to the destination. Start the autopilot
before starting to navigate to the point.
If the 557/567 has no autopilot, steer the boat
manually:
a use the boat position and destination on
the chart or highway windows
b or use navigation data window on the data
header (see section 2-8-3)
c or use COG and BRG on the compass (see
section 2-8-4).
Note:
1 If the XTE alarm is enabled, an alarm will
sound if the boat deviates too much from its
intended course (see section 15-8).
2 If the arrival radius alarm is enabled, then an
alarm will sound to show that the boat has
reached the destination (see section 15-8).
