Section 9 Route Planning 9-8
[4] [MAX Latitude]
Set maximum latitude.
A WPT can no longer be entered in a latitude higher than the latitude that has been set up.
If sailing is [GC], it is possible to create a route by automatically adding WPTs so as not to exceed the
maximum latitude in the case of a route in which part of the leg passes a latitude higher than the
maximum latitude.
If the maximum latitude is 60 or higher, a route can be created even if the GC leg exceeds 60.
If the GC leg exceeds 60 when the maximum latitude is 60, WPTs are automatically added and the
route is adjusted so as not to exceed 60°.
Note:
• A route cannot be created with a leg of 150 or higher in the longitudinal direction.
• Create a user chart at latitude 84° or lower.
[5] [Minimum Leg Length for Limit Check] combo box
Select a multiplier for determining the "minimum leg length" that is used for limit check from 1, 2, 4, 6,
or 8.
Calculation expression: Minimum leg length = (Hull length) x multiplier
60N
WPTs (W001 and W002) in this example are added so as not to
exceed the maximum latitude (60
).
The segment between W001 and W002 becomes an RL leg.
