4 Route Planning
4-6
c) Default
Set the default of the route to be created during route planning.
• XTL PORT: Port side width
• XTL STBD: Starboard side width
• Arrival Radius: Arrival radius
• Speed: Planned ship’s speed
• Sail: RL (Rhumb line)/GC (Great circle)
• ROT: Turn rate
• Turn Radius: Turn radius
• Time Zone: Time zone
d) Max. Latitude
Waypoints cannot be set in latitudes higher than the set latitude. If a GC leg is higher than
the set latitude, waypoints are added for limiting the GC leg to the maximum latitude.
When the maximum latitude is 60° or more, a GC leg exceeding 60° can be input.
Waypoints are added at intersections between the GC leg and 60°, so a leg exceeding 60° is
not input.
e) Check Safety in Editing
During editing the route, safety check is automatically conducted.
(You can manually conduct safety check with the [Safety Check] button.)
If an error is detected during the safety check, the route will have to be reset.
(The error part is drown in black color after safety check.)
Note:
• The route cannot be created if the GC leg extends over 120° and more in longitudinal direction.
When the GC leg between W002 and W003
exceeds the maximum latitude (60°N)
W003 and W004 are added for limiting the
GC leg to the maximum latitude (60°N).
