Displaying Route
Information
Using Route Information to Review Your Passage Plan
You can view data for all the waypoints in the current route, or any saved route.
You select the route from the database list and the information is displayed in a
Route Information pop-up; the following details are provided for each
waypoint:
Position
Bearing (from previous waypoint)
Length of leg (from previous waypoint)
Total Length
Time (ETA or Elapsed)
Soft keys are provided to toggle the time between ETA or elapsed and to
change the Speed Over Ground (SOG) value; the ETA for each waypoint is
calculated using the selected SOG, so you can change the SOG to determine its
effect on your ETA.
The chart scenario Review Your Passage Plan on page 2-30 provides a simple
example of how to use the route information.

1. Press the
ROUTE soft key, followed by MORE, then press ROUTE LIST. The

time.
The soft keys allow you to toggle between ETA or total (elapsed) time,
and to change the Speed Over Ground (SOG) value used in the time calcu-
lations. The current selections are highlighted.
