9.4.1 How to use the Waypoints page
The following fields and boxes can be found in the [Waypoints] page. Scroll the list
rightward to see hidden items.
WPT: Each waypoint has a number.
Name: You can name each waypoint.
Latitude: WPTs latitude coordinate is dis-
played in WGS-84 datum.
Longitude: WPTs longitude coordinate is
displayed in WGS-84 datum.
Leg/°: Bearing of leg (True: reference to
North). The bearing of legs can be changed.
Right click a bearing to show the context
sensitive menu. Select [Adjust Position],
then set bearing in the pop-up window.
Leg/NM: Length of leg (nm). The display
method can changed by right clicking the
column title to show the context sensitive
menu. [Each] shows the distance of each
leg. [Total] shows the total cumulative dis-
tance from leg to leg. [Remain] shows the
distance remaining from leg to leg. Note that
these settings are reflected to [Leg/NM] in
the [Waypoints] page of the [Monitor Infor-
mation] dialog box.
Str Mode: Define steering mode for each
leg - rhumb line or great circle. Click to select
[Rhumbline] or [Greatcircle].
RAD/NM: Define turning radius for each
waypoint. To change a radius, put the cursor
in this column to show up and down arrows.
Click the arrows to set the radius.
XTD LIM/m: The radio button [XTD LIM] de-
termines how to set the channel limits. The
[Symmetrical] setting shows [XTD LIM/m] in
the setting window, indicating that the port
and starboard channel limits are equal.
[Asymmetrical] replaces [XTD LIM/m] with
[XTD Port/m] and [XTD Starboard/m], allow-
ing individual setting of port and starboard
channel limits.
Plan SPD: Define planned speed to use with
a leg.
SPD Max: Define maximum speed to use
with a leg.
Margin/m: Define extension for channel lim-
its to be checked against chart alerts.
PL 1/m, PL 2/m: One or two sets of parallel
lines, colored orange, can be drawn on a
route. Set the distance (in meters) to offset
the lines from the route, from -99999 to
99999. Parallel lines allow the navigator to
maintain a given distance away from haz-
ards. See the illustration below.
XTD LIM (radio button): Selects how to set
channel limits - port and starboard channel
limits are equal or not equal
Local Time: Use local time. Enter the time
difference between UTC and local time.
