Function 
Input information 
Output information 
2.2 Fix rudder setting 
poinls 
2.2.1 Record input data 
• Manoeuvre to be carried out for 
each course changing point, 
specified by ROT or turning ra 
dius 
• Manoeuvring capabilities 
• Necessary input data are available for determining the 
rudder setting points 
2.2.2 Evaluate data 
• Output information from 2.2.1 
• Rudder setting point for each course changing point 
2.2.3 Provide set data 
• Output information from 2.2.2 
• Output of rudder setting points for user 
• Storage of rudder setting points for further processing 
3. Stipulate track limits 
3.1 Determine maximum 
longitudinal deviations 
3.1.1 Record input data 
• Shipowner's stipulations 
• Specific stipulations for the 
location considered in each 
case (eg deadline for pilot 
transfer) 
• Necessary input data for determining the longitudinal 
deviation, assigned to the particular location consid 
ered 
3.1.2 Evaluate data 
• Output information from 3.1.1 
• Maximum difference in time or way at selected points 
along the track 
3.1.3 Provide set data 
• Output information from 3.1.2 
• Output of maximum longitudinal deviations for the user 
• Storage of the maximum longitudinal deviations for 
further processing
