Screen 6 - Waypoint Control

The Navigation Option allows you to define a navigation route and enter the
latitude and longitude of each waypoint included in the route. Knowing the route
information and the coordinates of each point, the receiver can compute the
distance between the present position and the next destination point (DTD), the
course to follow to reach the next destination point (CTD), the time required to
reach this point (TTD) based on the present speed over ground, and the cross
track error (XTE) which is the deviation from the track between the present
position and the next destination waypoint. All this navigation information is
displayed in Screen 2.
After accessing Screen 6 (Figure 3.26) the top line indicates the route information,
in terms of waypoint numbers, where the current leg is highlighted. The remaining
screen displays a list of records showing the current and next waypoints in the
route. Each waypoint record consists of a 2-digit waypoint number, a 7 character
name, a latitude, and a longitude. Coordinates are entered in degrees, minutes,
decimal minutes. Up to 99 waypoints can be stored and a route can be composed
of up to 20 waypoints.

If no information has yet been defined, Screen 6 shows the route with only
waypoint 01, and the list of records show waypoint 01 with no name and
coordinates.
