Part 2 - Operating Information

HB-0844-02

2-

25

Note

Requires heel sensor.

This incorporates leeway (Course Made Good) into heading.
Leeway can only be calculated if you have the heel sensor fitted.
Course is the better function for most navigational purposes and
should be used whenever possible.

2.11.12 Course Over Ground

Menu Heading:

WAYPOINT

Function Text:

CRSE O/G

Update Rate:

Provided by position fixer

Units:

Degrees magnetic, true

Note

Requires interfaced position fixer.

Once the position fixer is connected and sending information, it
automatically appears in the menu and becomes available for
display. This is your actual track over ground and is invaluable to
the navigator for dealing with tidal areas.

2.11.13 Dead Reckoning

Menu Heading:

NAVIGATE

Function Text:

D/R CRSE or D/R DIST

Update Rate:

Once per second

Units:

Degrees magnetic, nautical
miles

Notes

1. Course and distance.
2. Corrected for leeway if heel sensor fitted.
3. Resettable as a trip function.

Formerly the mainstay of all offshore navigation, now with such
widespread use of electronic position fixing equipment it is more
often used as an essential back-up. It can be particularly effective
as an indicator of the net course steered on long offshore legs.
Both the course as a bearing from the start point, and its distance
in nautical miles, can be displayed as separate functions. If the
heel angle sensor is fitted then the course calculation will include
leeway correction.
