ETA Calculator
The ETA Calculator window enables you to
calculate the time, speed and distance between
waypoints on a monitored route.
With a route loaded for monitoring, click on the
ETA Calculator sub menu from the Routes
menu. The window includes the following
editable units, based on the values displayed in
Monitor Route:

Distance - the distance own ship must
travel to the end of the monitored route.

Speed - the calculated average speed to make the ETA indicated
at end of monitored route, or for the selected waypoint.

Time - the estimated time (in days, hours and minutes) to travel to
the end of the monitored route.

ETA - represents the ETA (date and time) of own ship at end of the
monitored route.
If the ETA Calculator is opened when there is not a monitored route plan,
the following default values apply:

Distance defaults to 1.0NM

Speed is own ship's current SOG.

Time is the time it takes to travel the Distance based on the speed.

ETA is the date and UTC time own ship is expected to arrive at the
Distance based on the speed.

1. Click on the WPT. button, the following
Action Required window lists the
waypoints in the route and the current
distance of each waypoint from own
ship.
2. Select a waypoint from the list and click
