the screen.
Waypoint 0, the first waypoint, is your Point of Departure, or the position you were at
when you created the route. Waypoint 0 is a unique waypoint, in that the CDU internally
changes the position of Waypoint 0 to your present position. However, the CDU saves
and displays the original coordinates entered when you created the route.
Waypoint 0 is displayed in Inverse Video, that is, white characters on a black background
(when in the normal Daylight display mode; see CFG1 Lighting). This indicates that
you have already passed this coordinate. The time stamp at the lower portion of the
description window indicates when the route was created. If you want to adjust your point
of departure position, you can edit Waypoint 0 in the WPT function.
To the right of the coordinate window of Waypoint 0 is a bent arrow. The bend in the
arrow is adjacent to the range and bearing between the waypoint you just passed and
the waypoint you are approaching. Keep in mind that these are the fixed calculated
values between these two coordinates and not the real time changing values that you
will see in the navigation screens between your present position and your next waypoint
during normal navigation.
Below Waypoint 0 is the waypoint you defined in the GOTO function. Notice that this
information is in standard video, black characters on a white background, and that an
ETA time is displayed in the same position as the waypoint passed time in Waypoint 0.
This indicates that the waypoint has not yet been passed. Remember that the ETA time
is filtered over time, so allow a few minutes for the filter to settle when you first get
underway or make course and speed changes.
