SPD 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. If speed profile is selected as trial speed, ETAs
based on Trial speed are calculated even if time table optimization is in use.
• Current: The system calculates ETAs using average speed of last five minutes. Note that if the speed profile is
selected as Current, own ship average speed (i.e., speed for calculation) the Trial speed box is replaced with the
Average Speed box.
