Furuno FEA-2107 - Optimizing a Route; Planning a Speed Profile

13. Route Planning

13.6.2 Optimizing a route
You can define Estimated Time of Departure (ETD), desired number of waypoints and Estimated Time of Arrival
(ETA) on the Parameters page in the Plan Route dialog box to optimize your route.
1. Place the cursor on Route in the status bar and then click the Plan button to open the Plan Route dialog box.
Click the Parameters tab to open the Parameters page. Check Enable changes.
2. Choose desired optimization strategy from the Optimize field. Spin the thumbwheel to choose desired strategy
and then push the thumbwheel.
3. Enter speed limit, ETC/UTC, ETA/UTC (Max. speed not required) in respective boxes.
In case of optimization by “max. speed”
With entered EDT as reference, ETA is calculated with entered speed limit. ETA may be entered in ETA/UTC box,
however ETA is shown below it.
The monitor display shows ETD, speed limit and calculated ETA.
13.6.3 Planning a speed profile
A speed profile is defined by general max. speed and optimization types. These values are given while planning a
route. You can define speed limit and optimize type in the Parameters page of the Plan Route dialog box and in the
WP page of the Plan Route dialog box you can give min. and max. speed for each leg. The table and illustration
below demonstrate how different optimize types and speed limits influence speed.
