speed profile for calculation in the Monitoring page of the Monitor Route dialog box.

ETA WP:
Indicates waypoint number of special ETA waypoint and estimated time and distance to it.
Final WP:

Monitored route is optimized
using “Max Speed”.
Speed profile:
There are three calculation strategies:
• Plan: The system calculates with optimization made in route planning.
• Trial: You can enter speed to test ETAs with different speeds.
• Current: The system calculates ETAs using average speed of last five minutes. Note that if Speed profile is
chosen as Current, own ship average speed (i.e., speed for calculation) the Trial speed box replaces the Average
Speed box.
