Speed Planning
Speed Planning allows the operator to manually specify a plan for speeds
to be used on remaining segments of the monitored route, and see what
arrival times result from these plans. It also enables a desired arrival time
(for any given waypoint) to be specified, and see recommended
adjustments to planned speeds needed to achieve this arrival time.
Planned speeds or computed adjustments to these speeds may
subsequently be used to control the ship’s propulsion system. For
information on propulsion control, refer to Chapter 3 `Propulsion’ in the
Supplementary Features User Guide 65900014.
To activate Speed Planning on a monitored route:
1. Load the route to be monitored from the Monitor Route - Route
Tab.
2. From the Routes menu, open the Speed Planning window. Note
that before speed planning begins the window displays no data on
the currently monitored route.
3. Click on the Edit Speed Plan button at the bottom of the window.
The Speed Planning Setup window appears on the chart display.
