Route ETA
The Route ETA (Estimated Time of Arrival)
enables the following settings to be changed or
selected on a monitored route:

Waypoint selection - click on the drop down
arrow to select a waypoint on the monitored
route. The field to the right gives the
calculated distance (in nautical miles) from
own ship to the select waypoint.

Speed - enables the speed for a route's
present leg (based on the waypoint
selection) and the speed for future legs to be
changed, either from the speed based on
own ship's SOG, or any planned speeds
given when the route was edited, see Edit
Route – Waypoints Tab. The planned
speeds show 10.0 kn if no changes were
made to the approaching and departing legs for each waypoint on the
route.
To change Route ETA settings do the following:
1. Manual speed defaults to 0.0 kn. To enter
a speed for the present leg or future legs
select the Manual radio button and click in
the Manual field, the text changes to
green (editable). Move the trackball right
to increase the value and left click again to accept the value.
2. To change the speed for the present leg or future legs to the
planned speed entered at the Edit Route menu select the Planned
radio button.
Each leg of a route may have different speed settings selected.
When speed values are entered, or planned speeds selected, the system
then calculates the ETA based on the selected speed values.
1. To hide the speed options click the Hide
options button. The button changes to
display the speeds for present leg and
future legs.
2. Click the button again to return to the full
Route ETA window.
