SAFETY REGULATION
"
Attention!
For safety reasons, the preadjusted rudder limitation is also active
during R.o.T control.
If the preadjusted rudder limitation is too small, then the preadjusted
speed value will not be reached.
"
Note
The desired rate of turn depends


on the initial turning behaviour of the ship
and on the adjusted parameters.
When the ship starts turning, the rate of turn may be increased up to
approx. 50%!
"
Caution
Turning behaviour with preset rudder limitation:
If the adjusted rate of turn is not reached due to rudder limitation, the
rudder limitation is to be extended only step by step. ( steps of < 5).
Otherwise, the rate of turn might considerably be exceeded because of
the integral component of the controller.
"
Note
Set course inputs differing by more than  180 from the
instantaneous heading of the ship are executed by NP 2025 PLUS
through the shorter way as a matter of principle.
In case of a heading change of 180 exactly, therefore, the direction of
heading change is uncertain!
"
Note
If the autopilot is connected via the steering mode selector or via an
external steering station, the main steering station is always switched
to the operating mode of Heading Control.

"
Attention!
The values for R.o.T. or radius which are preset on the NP 2025 PLUS
are overwritten by the external values (e.g. track planning system).
After switching back to e.g. Heading Control , check whether the
still--valid values for R.o.T. or radius provide for a safe heading-- or
track change!
"
Note
Operating mode of HEADING CONTROL
If the magnetic compass values and gyro compass values are
different, switching--over to the compass reference results in a
preset heading adaptation.
Possible course differences between set course and heading remain in
existence.
Operating mode of TRACK CONTROL
In this operation mode the actual heading may differ from the heading
indication, depending on the track error.

Changes of heading are to be done such that any unacceptably
high centrifugal acceleration is avoided (< 0.05g). This reduces
the risk of accidents to the passengers and any shifting of loads.
Computed relationship: a = d*v
a = acceleration (centrifugal acceleration)
b = turning speed when changing heading
v = travelling speed
You can see that the turning speed and the travelling speed have
a proportional effect on the acceleration. The turning speed must
be selected in relation to a desired maximum speed such that the
acceleration rates described above are not exceeded.
Turning speed limiting can be set at the autopilot.

Description
1.1
General
The NP 2025 PLUS belongs to the digitally adapted Autopilot family NAUTOPILOT2000.
The NP 2025 PLUS is a modern autopilot system, designed for all sizes of sea going
ship and for river navigation.
The essential components of the NP 2025 PLUS are:
-- Operating Unit 102--886 NG005
-- Control Unit
102--885
The NP2025 PLUS offers two operating modes, which after a request takes an individual
course-- or supports the already adjusted and loaded track control.

Identification NP 2025 PLUS
Switch--over to manual mode.
Press test button
simultaneously.
First display indication shows NP 2025 PLUS.

Non adaptive mode NP 2025 PLUS
Optimal heading-- or track control over the Quick Tune Function.
Quick Tune makes the adjustment and storing possible from up to 6 Parameter-groups which can through certain ships typical situation (Loading, Trim)
or weather conditions be brought back.
Aim; quick adaption to the ships behaviour by manual operation.

Adaptive mode NP 2025 PLUS
Optimal heading --or track control over the Economy or Precision Function.
Within this Function the NP 2025 PLUS reacts automatically to the current
weather conditions.
The operating mode Economy guarantees a satisfying reduction to the rudder
movement through a reliable remaining course position.
On this occasion the swell frequencies are standardized through a special filter.
Aim; Automatic reduction of the rudder movement, means a slight forward
thrust loss and with that less fuel.
The operating mode Precision guarantees an exact course position.
The Rudder movement will be notably reduced by using the yawing settings.
Drift compensated track change in the track control mode.


Differences between NP 2025 PLUS and NP 2025 normal version
The differences between both versions relates to the track control mode.
The track controller NP 2025 PLUS has additional features in terms of a position
drift filter with calculates the drift vector on a straight lag and during radius
controlled track change.
The benefit is a higher accuracy and a better performance especially on a radius
turn comparing with NP 2025 normal version.
The NP 2025 PLUS enables the following operating modes.
-- heading control with gyro compass
-- heading control with magnetic compass
-- heading control in connection with a track planning system (e.g. GPS)
-- change of heading with preset R.o.T.
change of heading with preset radius
-- rate--of--turn control in conjunction with a R.o.T. Tiller
-- heading control with an external preset heading transmitter
The NP 2025 PLUS system is put together from the following components
-- 1 Control unit as a main control panel

Optional System extension through the continuation of the NP 2025 PLUS
control unit e.g. a second control panel is possible
-- 1 Control Unit
depending on the inserted universal target-- respectively expandable as for
example:
-- NP 2025 PLUS as a self dependent system
-- NP 2025 PLUS in connection with an external follow--up control
-- NP 2025 PLUS as a combination of an autopilot system a gyro compass
system STANDARD 20 Plus.

Operating Modes
1.2.1
Heading Control Operation
The HEADING CONTROL operating mode is activated by changing the control switch to
AUTO.
The momentary heading of the ship is displayed in the heading display and in the preset
heading display.
The preset heading preadjustment is set via the rotary knob. The heading controller begins with the change of heading within the range of the preset parameter values (such
as, e.g. radius-- or R.o.T. limit value) and the alarm threshold (heading failure, rudder limitation).
The heading reference -- magnet compass or gyro compass -- is selected via the operating unit. Compass value deviations are recognized.
An existing preset heading / heading deviation is taken into account when
switching over. This results in a preset heading adaptation.

Autopilot
Parameter Yawing, Rudder and Cnt. Rudder
Yawing
The yawing setting determines rudder activity and course accuracy for the autopilot‘s
control properties.
The optimum setting is obtained by means of observation.
Yawing = 1 signifies control with greatest amount of activity (maximum
accuracy level).
Yawing = 6 signifies control with the lowest amount of activity (minimum
accuracy level).
If the setting is not optimised the steering gear can become over--stressed. Large rudder
angles cause loss of saeway.
Rudder
Each course deviation needs to be corrected by means of a rudder size typical to the
ship. The rudder setting determines the ratio of rudder angle to course error.
Rudder too big:
-- Unstable behavior =>
=>
over--reacts to a course correction
Overshoots when course is changed
Rudder too small:
-- Course control too inaccurate
=>
preconfigured rotation speed not reached during course
change manoeuvre
Cnt. Rudder
Based on its bulk and load, each ship has a time constant typical to the ship, which
needs to be kept in control during course change manoeuvres.
Before the new set course is reached to the turning speed needs to be reduced in good
time (e.g. of a counter rudder).
This effect is achieved by the counter rudder setting (Cnt.Rud).
Counter rudder too high:
The ship is stopped before it reaches the new set course.
Counter rudder too small:
The ship does not stop in good time and overshoots the pre--selected set course.

Heading preadjustment more than 180
There are two different possibilities to adjust the heading preadjustment.
1.Preselected Heading
Heading adjustment und acknowledgement of the adjusted value by the Set--key.
In this mode the ship follows the respective heading adjustment within a range of
0 to 359,9. It means, there will be an all--around circle.
For example: Actual heading is 270.
New heading will be 280.
Direction of roation should be Port.
The new heading will be 280 after a around circle of 350 with a
direction of rotation to port.

2. Direct heading
The rotary knob has to be pushed--in while the heading value is adjusted.
In this mode the ship follows at once the new value and a change of heading can be
more than an all--around circle.
Caution:
In case of a malfunction, it means a heading--jump with an adaption to
the new heading value, the initialized heading--change--maneuovre will
be aborted.

Operation with a Pre--Switched External Preset heading Transmitter
ATTENTION
This mode can only be performed with an
external navigationsystem.
The system application “Autopilot (REMOTE)”
is only allowed under use of an approved track
control system.
The preset heading preadjustment is determined here by the navigation system and
transmitted to the NP 2025 PLUS via a serial interface.
The EXTERNAL status display lights up.
The NP 2025 PLUS executes the heading control within the range of the parameter
preadjustments.
The mode REMOTE has to be activated by the contact on terminal board L2.47 and
L2.48 (see service manual Annex 1--4).
During this operating mode, the following characteristics of the NP 2025 PLUS operation
are not available:
-- switching over to another operating mode (e.g., track control)
-- consideration of preadjusted radius or R.o.T--values of the NP 2025 PLUS,
as these values are deleted and replaced by external values,
-- preadjustment of the preset heading via the rotary knob

R.o.T. Tiller Operation (Option)
This system concept simplifies steering and makes turning manoeuvres of the ship easier on rivers and canals.
The rate of turn of the ship is set by pressing the R.o.T Tiller.
The preset heading and the actual heading are identical.
The R.o.T. controller in the NP 2025 PLUS then determines the rudder angle necessary
to attain and hold the preadjusted R.o.T.
For safety reasons, the preadjusted rudder limitation is
also active during R.o.T control
If the preadjusted rudder limitation is too small, then
the preadjusted speed value will not be reached.
ATTENTION
The control dynamic of the R.o.T. controller can be adjusted via the YAWING parameter:
YAWING 1
=>
hard controller adjustment
YAWING 2
=>
normal controller adjustment
YAWING 3....6
=>
smooth controller adjustment
During this operating mode, function key
(used in setting the limit value) is
deactivated.

Secondary Operator Units
Within an NP 2025 PLUS system, several operator units may be managed. If there is no
active disturbance (alarm that is not acknowledged), change--over between the operator
units can be performed.
Change--over is made directly via the command keys of the operator unit concerned:
-- In case of same operating mode, the preset heading preselection is maintained
-- If the operating mode is changed, the preset heading is equated with the heading.
Passive operator units are switched to operating mode STANDBY.
STANDBY means;
-- Indication of preset heading and heading
-- Status indication of the heading sensor
-- Indication of parameter group
-- No possibility of adjustment via function keys
-- Operator unit can be selected via command keys
Any active operator unit permits unrestricted system operation and parameter management.

Preadjustment for the Heading or Track Change Manoeuvre
Preadjustment takes place via a double--function key:
-- Rate of Turn determines the maximum rate of turn (/min), by which a heading or
track change manoeuvre is performed. Entry of parameter value see Section
2.13.3 Limit Values.
-- Radius determines the turning circle radius by which a heading or track change
manoeuvre is performed. Entry of parameter value see Section 2.13.3.7 Limit
Values.
-- Radius & RoT -- values are calculated and transmitted by the trackcontrol
system (ECDIS)
Note
During a heading or track change manoeuvre, do not
change the R.o.T radius preadjustment!

* Rudder bias
A bias rudder angle is a rudder bias which, via integral parts of the heading control, automatically sets in as a result of disturbances on the ship.
The aim, despite a disturbance, is to keep the ship on the preset heading.
Constant disturbances can be produced, by wind, rough sea or asymmetrical pressure,
e.g. whilst towing.
Particularly for the disturbances wind and rough sea, the constant rudder can only be
correct for a particular heading range. For this reason, the integral proportion (constant
rudder) of the heading regulator is deleted when there is a change in preset heading of
>20.
As well as an automatic rudder bias, a manual bias can also be installed. This can be
achieved through a change in the value of the parameter Rud.Trim.
For normal drive/maneuver the parameter Rud.Trim must be set at 0.

Rud.Trim 0 means:
The rudder bias will automatically be determined from the autopilot.

Rud.Trim for example 3 means (the automatic rudder bias is not active):
during for example towing the approximate heading will be determined.
Through changing the value of the Rud.Trim a stable heading can be achieved.
The optimal parameter value is revieled by observing the heading direction.

Information on Heading Monitoring OFF Heading
The function heading monitoring is active during operating mode Heading Control.
The heading monitoring has two essential functions:
-- Monitoring of Off Heading during course--keeping operation
-- Monitoring of track change phase via a time window
Monitoring of heading differences during course--keeping operation
The function Course Alarm Monitoring monitors deviations from the preselected desired
course of the ship. The monitoring threshold is set via the control unit
(see section 2.13.3.3) and allows settings in a range of 5 to 30 degrees.
If the ship leaves the desired course and thereby exceeds the preselected monitoring
threshold, an optical and acoustical alarm is triggered. The autopilot is provided with a
potential--free alarm contact which, for example, enables the control of an additional
alarm unit.
Monitoring the track change phase via a time window
The alarm is suppressed during the off heading phase.The time window is calculated
from the difference in the desired course and the pre--selected turning rate.
If during the track change manoeuvre the ship enters the heading alarm threshold within
the time window, no alarm is triggered.
Note
The desired value for the rate of turn (R.o.T. see section 2.13.3.5) depends on the
ship.The ship must be able to perform the turning value.Desired rate of turns exceeding
the turning capability of the ship results in triggering the heading alarm prematurely.
If the ship leaves the desired course and thereby exceeds the preselected
monitoringThis effect can also occur if the rudder limit is adjusted (rudder limit see
section 2.13.3.2) too closely when more rudder deflection is needed.
On taking the autopilot into operation make sure that the basic setting of the course
controller is precisely adjusted (trials). For the control of the turning rate a sufficient
rudder amplification (optimize rudder parameters) must be ensured.
If the desired course, the radius, or the turning rate are changed during the track change
manoeuvre, the time window will be immediately calculated new.

System Messages
As a matter of principle, system messages are indicated via the text line as plain text information. Dependent on the significance of the messages, a text in the text line is overwritten by the system message. The plain text info is represented by an audible signal
and by the flashing LED of the symbol key.
System messages can be subdivided into 3 categories:

Alarms, the audible signalling releases a continuous sound, the LED of the
is flashing. Within the text line, a plain text information in acc. with the
alarm appears.
On the operator unit, no inputs can be made. After the alarm has been acknowl-edged, the signalling is deactivated (see Section 2.12.1).
The operator unit can now be used again.
The error message is written into a memory until elimination of the disturbance.
The LED
of the key is lit permanently
By actuating the
key once more, all error messages stored in the memory
can be indicated one after another.

Warnings, every 90s, a sound is heard three times from the audible signalling,
the LED of the
key is flashing. The text info appears in the text line for
approx. 15s.

Heading
The change of heading will immediately be started-depending on the pressed rotary knob. The ship begins,
e.g. to turn with the preset R.o.T. (RATE OF TURN) onto the
preset PRESET HEADING adjustment.
During a heading change, the ship follows always the direction of
the set heading user input.
A preset heading change will be achieved by turning the rotary-knob; this can result in the following possibilities;
For the prepared change of heading
Set the Preset Heading by turning the rotary knob.
Actuate the Set key.
For an immediate change of heading
Press and turn the rotary knob, the ship will begin at once
with the change of heading.
Depending on the configuration, an automatic R.o.T. limitation
will be set at120/min during an R.o.T. maneuver.
This automatic preselection does not apply in case of
an R.o.T. limitation which is already >120/min.
The following situation results:
The OFF HEADING monitoring is deactivated for the duration of
the heading change.
The resulting rudder activity can be displayed via the Display
key (see section 2.13.4 ).
The change of heading is completed when the HEADING display

This operating mode requires an external R.o.T. Tiller.
The tiller is ready for use on actuating the key.
The steering selector switch is in the EXTERNAL position.
The NP 2025 PLUS is guided by a previously connected control
panel with serial transmitted set heading values.
The values preset at the NP 2025 PLUS for
R.o.T. or radius are overwritten by the external values.
After switching back (e.g. to Heading Control)
check whether the external values for R.o.T or Radius
(which are still valid) assure a safe heading or track
change!
The following situation results:
-- The following displays remain unaffected:
Preset Heading / heading
Heading sensor
Alarms (without a signal sound)
Current parameter groups
Preset info in the text line
-- Limits to operation
Command keys are locked.
---
Turning behaviour with preset rudder limitation:
If the set R.o.T. is not reached due to the
rudder limitation, the rudder limitation may only be
increased in steps (in steps of <5).
Otherwise, the R.o.T. might be considerably exceeded
as a result of the integral content of the controller.
The following situation results:
-- The limit value setting (for Radius or R.o.T.) is switched off
during the time the R.o.T. Tiller is steering the ship.
-- Every tiller adjustment is immediately effective
The tiller operation can be cancelled at any time by actuating
the command key.
The turning speed will be determined by the turning
behaviour of the ship and the set parameters.

ECDIS CHART STATION and ROUTE DIGITIZER
The ECDIS CHART STATION intended primarily for route planning and monitoring has a
high resolution colour display. It could be combined with a digital chart table (large format digitizing table).
By placing a sea chart on the tablet‘s surface and digitizing a planned route on the chart
the coordinates of the waypoints are converted into digital format and saved in the
ECDIS System. On the ECDIS BRIDGE STATION the stored route can be displayed and
used for track control.

Function
Heading Control
The adaptive heading controller can be operated from autopilot operator unit as well as
from ECDIS console integrated Autopilot Remote Control Panel (ARCP). A take--over
system between ARCP and autopilot makes it possible to change during heading control
the preset heading and radius settings via the ARCP. The preset heading and the radius
are displayed at the ECDIS.
An override of heading control can be carried out by a NFU tiller on the active ARCP.
Track Control
ECDIS BRIDGE or CHART STATION with or without DIGITIZER generated routes can
be used for automatic track keeping. The track control function can be activated at the
ARCP.
An override of track control can be carried out by a NFU tiller on the active ARCP.
Data Management
All navigation information (heading speed, position, depth, wind, drift) is managed by
NAUTOCONNING. In case of several sources of the same type of data (e.g. position),
the data is selected and distributed throughout the system. Thus all information for the
track control system is provided centrally by NAUTOCONNING. In case of data failure
an alarm is generated.
Heading Distribution
The heading information is distributed by the gyro compass STANDARD 20/22 system.
Systems which require a high update rate (autopilot, RADAR) receive the heading information via the course bus. Indication and monitoring devices (NAUTOCONNING) receive the heading information via the Data Distribution bus.
The heading reference (Gyro 1/Gyro 2/Magnetic compass) is selected at the NAUTOCONNING or at the operator unit(s) STANDARD 20/22.
Position Distribution
The position information is read in at the ECDIS and transmitted to the Data Distribution
bus (Option). NAUTOCONNING or ECDIS takes over the selection of the system master
position. NAUTOCONNING and RADAR receive the position via the data manager.
STANDARD 20/22 receives the position via the Data Distribution bus. The autopilot gets
it directly from the ECDIS.

3680.DOC012
NAUTOGUIDE C
Operator Manual
Speed Distribution
The speed information is read in and managed centrally at the NAUTOCONNING. NAUTOCONNING also takes over the selection of the speed sensor. The speed information
is distributed via the Data Distribution bus and via the data manager.
Sensor Data Distribution (Wind, Depth, Drift, etc.)
These data are read in and managed centrally at the NAUTOCONNING. A selection between different sensors is not possible. The sensor data are distributed via the Data Distribution bus and via the data manager.
Alarm Management
The alarm manager as an independent unit in the NAUTOCONNING permits -- besides
the input and display of external alarms (binary contacts) -- protocolling on the NAUTOCONNING and distribution and signaling on its own signal units via serial data bus.
Subsidiary to it is a watch alarm system which monitors the connected navigation equipment (RADAR, ECDIS, autopilot etc.) for proper operation and, in addition to the reset
buttons, resets the watch alarm. When the prescribed period of time has elapsed,
alarms are given according to the rules of the IEC 62065 on up to the general alarm
(normally--closed contacts).
Conning Display
The conning display is part of the NAUTOCONNING SYSTEM. It receives the data and
alarms of all devices and sensors connected to the system and displays them on a
monitor.

2.3.1
Route Planning Digital Chart Data
ECDIS has sophisticated route planning capabilities.
During route planning, each route section is automatically checked for free and safe
passage of the ship. The automatically check--up comprises Prohibited Areas, Own
Ship’s Contours, Buoys and Beacons known from and indicated in the sea charts (93/3
and S57).
In case a dangerous situation is realized during route planning, a corresponding alarm is
displayed in the Alarm Window (see Fig. 1--1).

NAUTOGUIDE C
Operator Manual
ECDIS displays waypoints as circles. The active waypoint is marked with an additional
circle around it. If you label your waypoints, the labels appear below the marker. When a
route is established, the following information is automatically displayed:
1. A planned track (course line) between the waypoints (is red in colour and
appears as a thick dashed line between waypoints and a dashed line between
the ship and the active waypoint).
Using the route planning feature, a primary as well as a secondary route can be
created (see section 2.5). The route priority can be selected via menu function
as needed.
The primary route is displayed in thick, red, dashed lines.
The secondary route is displayed in thin, red, dashed lines.
2. The planned turning arc/radius (red in colour); the turning arc which was
established when you entered the waypoint.
The turning arc/radius is limited to maximum 135.
This limit value is checked during route planning and if this limit is exceeded
an error message is released.
3. Crosstrack limit boundaries: width defined by the current cross--track error
alarm setting.
4. The wheelover point, or the point at which own ship must start turning to follow
the predicted turning arc.
The wheelover point position is controlled by the “Turning Response” box in
the Autopilot dialogue box. Please see ”Driving an Autopilot” in the ECDIS
operation manual section 12.1.10.

Edit Route Command
The Edit Route Command enables the operator to create or modify routes by:
Enter and label waypoints
Move waypoints or change their labels
Delete waypoints from a route
Enter and change the planned turn radius/arc
Insert new waypoints in a route
Reverse the order of waypoints in a route
Name and save a route
When you choose the Edit Route command, ECDIS displays the Edit Route dialogue
box with the name of the open route in the title bar. If you are creating a new route, the
title bar reads “untitled”.
Planning a route is simply entering waypoints. You can use the Edit Route command to
enter a waypoint in two ways:
1. Positioning the cursor in the display.
2. Using the Latitude and Longitude boxes to enter specific coordinates.
While you are entering waypoints, Pathfinder/ST ECDIS automatically checks the route
and fairlane (cross track limits) for unsafe and restricted areas as well as to check if they
are reasonable (relative to their geometrical coordinates). If the fairlane or route is not
reasonable, and cannot be created, one of the two following message boxes will appear,

When these message boxes appear, you will not be allowed to enter this part of the
route. Acknowledge the message box by clicking on OK. If the route action is not accepted, you must change the location of the waypoint. If the geometrical limits are not
accepted, you may either change the waypoint, waypoint radius, or the Cross--track
Error Alarm (you may leave the Edit Route dialogue box open while you do this).
If you enter a waypoint in a restricted area, ECDIS will display a warning “Route Intersects Restricted Area”. ECDIS allows you to save routes containing a waypoint in a
restricted area.
Handling Primary Route and Secondary Route
The ECDIS is able to display two routes at the same time:
-- the first route which has been created or loaded is defined as “Primary Route”
-- the second route which has been created or loaded is defined as “Secondary
Route”.
Route priorities are indicated by the entry “Primary” and “Secondary” in the menu guide
(see ECDIS operator manual section 8.1.13).
When starting the Edit Route mode the operator is asked to select the Primary or Secondary route, if more than one route has been loaded.
If Track Control is active a modification of the active (Primary) Route is possible.
During this time the Secondary Route is faded out.
If the Primary Route is deleted by means of the function Clear Route, the Secondary
Route becomes the Primary Route

Track Control
There are several conditions to be met for activating track control:
-- a route is to be created with official chart data
-- the route has to be loaded
-- the ship is to be brought into an area close enough to pre--planned track
-- the automatic steering mode is required
-- the Start Waypoint of the route has to be selected
-- the type of track approaching manoeuvre has to be chosen:
GO--TO--Waypoint or GO--TO--Track)
-- the approach radius is to be selected and
-- track control has to be activated
In section 2.7 and following, the above mentioned steps are described precisely.
Approach manoeuvre types
The system offers two different types of approach manoeuvres
-- the GO--TO--Waypoint manoeuvre
-- the GO--TO--Track manoeuvre.
For a better understanding the difference between the two types of track approach manoeuvres are described in the following.
Edition: Feb. 05, 2004
GO--TO--Waypoint manoeuvre
(see Fig. 1--10 and Fig. 1--11)
GO--TO--Track manoeuvre
(see Fig. 1--12)
The main idea behind the GO-TO--Waypoint manoeuvre is, that
the selected GO--TO--Waypoint is
crossed. The start point is
thought to be laid in free water to
enter narrow water without any
risk. The geometrical restrictions
to be followed are shown in the
a.m. figures.
The GO--TO--Track manoeuvre is
the standard approaching manoeuvre.
It is used when a route should be
entered not at the beginning
or
entering a route after a track control interruption carried out by the
operator.
The following geometrical restrictions are to be met.

Approach radius
(see Fig. 1--13)
The radius for the approaching manoeuvre is user selectable at the “Track Control Activating Procedure”. The radius influences the shape of the approach manoeuvre from the
position where the Track Control Process is started to the preplanned track. The following sketches show the reaction of the system using a small or large approach radius.
This could be helpful to sail around obstacles when entering a preplanned track.
The radius could be decreased down to a ships specific minimum. The minimum value
as well as the default value is set by a service engineer.

Displaying the GO--TO--Waypoint of a Route
When you open the Steer to Track dialog box after creating or opening a route,
ECDIS automatically selects the first valid waypoint in the route as the active waypoint.
If you want to navigate to a different waypoint, you can do so by using the arrow keys.
When you select the new waypoint, ECDIS checks to make sure it is a valid course line,
then it circles the waypoint, redraws the course line, and updates the Information Panel.
If it is not a valid course line, then ECDIS grays the dialog box, except the Select Active
Waypoint arrow buttons, until a valid waypoint is selected. Selecting an active waypoint
is very useful when you are navigating a long route. For example, suppose you are navigating a route from Seattle to Pusan and decide to stop in Prince Rupert. When you are
ready to continue on to Pusan, open your route again, and then using the Track Control
command, you can reassign the active waypoint and continue on the route.

planned at ECDIS. If the approach radius is not modified at ECDIS, the last used radius will be taken. The selectable
minimum radius is ships specific and is to be adjusted by the service engineer.
When changing back to heading control, the navigation parameters change back to the parameters (and values) which
were active before track control has been started.
--
The rudder limit setting is automatically set to “Max”. The value cannot be varied during track control. In case of manual change--over to heading control, the old value is taken again.

The navigation parameter is set to “Radius” if “R.o.T. “ has been activated. For track change manoeuvres, the
NP2030/NP2035 takes the radius value planned at the ECDIS. This radius cannot be varied on the operator
unit of the autopilot.
For the approaching manoeuvre (the way from the actual ships position to the preplanned track) a radius
can be planned at ECDIS. If the approach radius is not modified at ECDIS, the last used radius will be taken.
The selectable minimum radius is ships specific and is to be adjusted by the service engineer.

Interruption of Track Control in case of a Defect
In case of any failure of the system it is not necessary for the officer of the watch to react
immediately. The system becomes degraded to the next lower steering control mode
level and continues started manoeuvres as far as possible.
Note!
There is one exception from that.
In case of loosing the heading reference it is not possible for the system to continue the
course of the preplanned track in a fall back mode.
In that case the present rudder angle is frozen, the rudder motion will be stopped (IMO
requirement).
The operator has immediately to take over via Override Tiller or select Hand Steering
Mode via Steering selector Switch.
During track control mode two different phases are distinguished:
1) the ship is sailing on a straight track leg
2) the ship is in a track change manoeuvre
Interruption of track control leads to two different reactions depending on the phase the
vessel is in, see the following Sections.
A summary is given section 2.17.
