Time Schedule with Planned Speed
In order to adapt the initial time schedule of the route to a constant speed for the entire route or to a
specified speed profile, perform the following steps:
1. Select the arrival point and in its ET Mode field set the mode to Calculated.
2. Verify or change the maximum speed values in the MAX SPD fields according to your needs.
3. In the Planned Speed field enter the required speed value and click on Set.
This will result in a new calculation of the time schedule for the entire route based on the set departure
time and the planned speed value, but taking into account those legs which have a speed limitation set
by the MAX SPD values.
If the route contains an arrival point in the ET column and the Planned Speed is entered, you will get a
warning that this will be changed to Calculated and the arrival time is lost.
With [Clear] you can make the Planned Speed invalid, so that the time schedule can be recalulated
based on the set arrival and departure times.
Notes:
If the maximum speed is achieved in all calc. SPD columns, the arrival time cannot be made shorter.
In this case an earlier arrival time will also lead to an earlier departure time. In the same way a later
departure will create a later arrival time.
If you must achieve an earlier arrival time and an earlier departure is not possible, the MAX SPD values
could be increased until an upper limit is reached, which is specific for your ship under the prevailing
conditions.
