2.2.1
Route planning
A route can be created two ways: Modify an existing route to create a new route or create a new route from scratch.
A route consists of the following:
• Position of each waypoint
• Turning instructions for each waypoint
• Safety limits between waypoints (channel limits)
Information notebook:
•
Information pages to alert the operator to a given waypoint or a selected area.
•
Automatic and/or manual notebook function to tell operator position-based information.
Voyage optimization parameters: See "voyage optimization" below.
2.2.2
Route calculation
Route calculation for voyage planning includes the following:
Route profile calculation:
• Distance between consecutive waypoints
• Course between waypoints
• Calculation of wheel over point
Route check: Grounding alert based on available depth information in digital chart database.
Voyage optimization:
•
Timetable optimization
•
Optimization based on economical factors
The ECDIS processor calculates optimum speed and course between each waypoint, ETA, and fuel consumption,
based on the defined data. There are four calculation strategies: Max. Speed, Timetable, Lowest Cost and Best
Profit. In case of Great Circle sailing between two waypoints, the ECDIS calculates minimum and maximum
latitudes, and if needed adds an extra waypoint(s) so as not to exceed minimum and maximum latitudes.
