Functionality  level  1

Functionality  level  2

Function

Input  information

Output  information

1.  Determine  local  circumstances ­


1.1  Consider  trafficdiverting
  measures

1.1.1  Record  input  data

•  Coastal  sea  charts
•  Regional  sea  charts
•  Sea  handbooks

•  Information  on  speed  restrictions,  traffic  separation
regions,  stipulated  waterways

1.1.2  Evaluate  data

•  Output  information  from  1.1.1

•  Selection  of  the  information  on  traffic-diverting  measures ­
  of  relevance  as  regards  the  track  being  planned

1.1.3  Provide  set  data

•  Output  information  from  1.1.2

•  Information  is  available  for  further  use  in  the  system

1.2  Determine  obstacles

1.2.1  Record  input  data

•  Coastal  sea  charts
•  Regional  sea  charts
•  Sea  handbooks

•  identification  of  obstacles  such  as  shallows,  roads,
prohibited  zones,  fixed  installations  at  sea

1.2.2  Evaluate  data

•  Output  information  from  1.2.1

•  Selection  of  the  information  of  relevance  as  regards  the
track  being  planned

1.2.3  Provide  set  data

•  Output  information  from  1.2.2

•  Information  is  available  for  further  use  in  the  system

2.  Stipulate  track

2.1  Determine  fuming
radii,  ROT  or  rudder
position

2.1.1  Record  input  data

•  Route  or  course  changing  points
•  Set  speeds
•  Ship  data  (manoeuvring  capabilities, ­
  load/stability)

•  Set  courses,  amount  of  particular  course  change  necessary ­

•  Boundary  conditions  for  cou  rse  changes

2.1.2  Evaluate  data

•  Output  information  from  2.1.1

•  Turning  radius,  ROT  or  rudder  position  for  each  course
changing  point  (way  point)  of  the  track

2.1.3  Provide  set  data

•  Output  information  from  2.1.2

•  Output  of  the  manoeuvre  to  be  carried  out  at  each
course  changing  point,  for  user
•  Storage  of  characteristic  values  for  course  changing
(i.e.  ROT/turning  radius/rudder  angle)  for  further  processing ­
  in  the  INS
