NAV2 - Basic Steering Information

Navigate screen 2 provides the bearing (BRG) and range (RNG) to
the waypoint you are approaching in large easily viewed characters.
Below these, you will see your actual Course Over Ground (COG)
and Speed Over Ground (SOG). The bottom portion of the screen
provides cross-track error information. Again, if you don't see the
information described here on your screen, you will need to create a
route in RTE1 first (refer to the Route section of the manual).
In the bottom half of the window, the vertical line in the center repre-
sents your course line. The checkered area on the left and right side
of this area represents the out of bounds or beyond the cross-track
error limit area. Whenever the boat is left or right of the course line,
the corresponding checkered area changes to solid black, indicating
the side of the course line that you are on. The number next to the
course line is your calculated cross-track error. The numbers in the
lower left and right hand corners indicate the cross-track limit you
set in the CFG1 menu under Navigation. You will notice that the
cross-track error limit lines are slanted, just as they were in the Pan-
orama screen. So if the boat is off to the right of the course, and the
bow is pointing straight up, you are actually traveling away from the
course line. Keep the bow pointed toward the top of the course line,
and you should be able to maintain your course without a lot of drift.
The BRG and COG values will confirm this for you, when executed
properly.
