Chapter 11 - Using the Trip Function
Introducing the trip function
What is the trip?
The trip is a sequence of
waypoints comprising a par-
ticular journey-in-progress:
a record of waypoints, coor-
dinates, and routes showing
where you've been and
where you intend to go.
In contrast, a route is a
sequence of waypoints
that's stored in the 961's
database.
Why use the trip?
Page 11-2
In 961 operations, the trip is a sequence of past, active, and
future waypoints. Like a route, the trip consists of a series of
waypoints, but unlike a route, a trip occurs in real time—as you
travel. Each waypoint that you navigate to is automatically
recorded in the trip.
If you're navigating to a waypoint and you decide to go to a
different waypoint, the 961 removes the original point from
the trip and adds the new point instead, ensuring that the
record of the trip remains accurate. Whenever you tell the 961
to go directly to a waypoint, any future points in the trip are
erased and replaced by the new point. Whenever you add a
waypoint to end of the trip, you'll go to any future waypoints
before the new one.
You can erase single points from the trip, or erase the entire
trip. You can save the trip at any time as a route in the 961's
database. Overall, the trip function provides a quick and easy
way to check on your progress as well as make changes while
you travel.
Of course, you can navigate with the 961 while ignoring the
961's trip function. You may want to ignore trip functions
while learning to use the 961.
In any case, you should regularly erase the old part of the
trip.
The trip can't "fill up" unless there are 250 future points in it.
Even when full, the trip automatically wraps around so that
the oldest points, but never active or future ones, are thrown
away to make room for the new ones.
The trip function has three major benefits:
•
it creates a record of today's trip by automatically adding
to the trip each waypoint that you navigate to—even those
waypoints that weren't part of your original route or
trip—including *MOBXX* and *SAVEDXX* waypoints
