Introducing avoidance points
What is an
avoidance point?
The term
avoidance point
refers to a specific position that you
enter into the database, and define by its radius and either its
lat/lon, or loran TDs, or distance and bearing. It indicates an
area you specifically want to avoid. By comparison, the term
waypoint
is used to refer to a specific point on the
CHART
screen that’s used as either an intermediate or final
destination.
Why use avoidance
points?
Avoidance points are user-defined areas that you want to
avoid crossing for reasons such as the presence of sandbars,
wrecks, and so on. Here are some of the functions you can
perform with avoidance points:
•
store up to 200 avoidance points in the database
•
quickly add any avoidance point
•
copy an existing avoidance point to create a new one
•
edit or erase avoidance points
How are avoidance
points used?
The 961/962 always checks your vessel’s position relative to
nearby avoidance points, and alerts you whenever you’re near
them. As soon as your vessel is on a course line with an
avoidance point, the yellow avoidance-point alarm appears on
all screens to alert you that an avoidance point is in your trip
(the avoidance point is
not
listed on the
TRIP
screen). This
means, for example, that when you decide to go to new
coordinates now, if this course line includes an avoidance
point, the yellow avoidance-point alarm will automatically
appear. If, instead, you decide to add the new coordinates to
the end of your trip, the yellow avoidance-point alarm will be
displayed as soon as you’re on the leg (but not before) that
includes the avoidance point.
As soon as you actually
enter
an
avoidance point, a red
avoidance-point alarm alerts you that your vessel is inside an
avoidance point. A general alarm (honk alarm output) will turn
on in 15 seconds if the alarm is not acknowledged.
