Input  information

Output  information

1.3  Monitoring  planned
course  changes

1.3.1  Record  set  and  actual ­
  values

•  Actual  position
•  Actual  values  for  ROT,  turning
radius,  rudder  angle
•  Ref.  track  (at  least  last  way
polnt/course  changing  point/next
way  point)
•  Ref.  value  for  turning  radius  or
ROT  at  course  changing  point
•  Manoeuvring  limits  (max.  rudder
position/max.  ROT)

•  Graphic  representation  of  position  and  movement ­
  of  ship  in  track  section  considered
•  Representation  of  preset  values  for  manoeuvre
at  course  changing  point
•  Representation  of  manoeuvring  limits

1.3.2  Compare  data

•  Output  information  from  1.3.1

•  Difference  between  position/movement  and
given  track  geometry
•  Deviation  between  actual  and  set  values  for
turning  radius  or  ROT
•  Difference  between  actual  values  for
ROT/rudder  position  and  manoeuvring  limits

1.3.3  Assess  comparison

•  Output  information  from  1.3.2

•  Statement  whether  position/movement  of  ship  is
within  the  limits
•  Statement  whether  set/actual  deviation  of  ROT
or  turning  radius  is  within  given  limits
•  Statement  whether  actual  values  for  ROT/rudder
position  are  within  given  manoeuvring  limits

1.3.4  Provide  result

•  Output  information  from  1.3.2
•  Output  information  from  1.3.3

•  Output  of  set/actual  deviations  for  the  user
•  Provision  of  deviations  for  use  by  other  functionalities ­


2.  Monitoring  of  course  and
heading

2.1  Monitoring  the
heading

2.1.1  Record  set  and  actual ­
  values

•  Actual  value  for  heading
•  Set  value  for  heading

•  Necessary  input  information  is  available

2.1.2  Compare  data

•  Output  information  from  2.1.1

•  Difference  between  ref.  and  actual  value

2.1.3  Assess  comparison

•  Output  information  from  2.1.2
•  Limit  value  for  deviation

•  Statement  whether  set/actual  deviation  is  within
the  limits
