2.9.13 Course Over Ground
Menu heading: WAYPOINT
Function text: CRSE O/G
Update rate: Provided by the position fixer
Units: ºM or ºT
Note
Requires interfaced position fixing system.
Once the position fixer is connected and sending
information, the information gathered automatically appears
in the menu and becomes available for display. This is your
actual track over the ground and is invaluable to the
Navigator for helping deal with tidal areas.
2.9.14 Cross Track Error
Menu heading: WAYPOINT
Function text: CROSS TR
Update rate: Provided by the position fixer
Units: Nautical miles
Notes
1. Requires interfaced position fixing system.
2. Analogue indicator available.
This is also sent direct from the position fixing system and
is necessary for keeping the yacht tracking directly in to the
target. Cross Track Error indicates how far you are from the
direct (Rhumb Line or Great Circle) as a perpendicular
distance and allows you to correct even the slightest
deviation. Although this may not be the objective, on long,
tidally affected legs you will plan to be swept first one way
and then the other. The Cross Track Error is useful for
monitoring your tidally corrected course to see if you have
the right offset, and that you are not being swept too far one
way.
