THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Directive 2005/44/EC of the European Parliament and of the Council of 7 September 2005 on harmonised river                           information services (RIS) on inland waterways in the Community(1), and in particular Article 5, paragraph 1, point (a), thereof,                        

Whereas:

(1)River Information Services (RIS) should be developed and implemented in a harmonised, interoperable and open way.

(2)The technical specifications for the electronic chart display and information system for inland navigation (Inland ECDIS)                              should be defined.

(3)The technical specifications for Inland ECDIS should be based on the technical principles set out in Annex II to Directive                              2005/44/EC.

(4)The technical specifications should take due account of the work carried out by relevant international organisations, notably                              the Resolution 48 ‘Recommendation on electronic chart display and information system for inland navigation (Inland ECDIS)’                              adopted by the United Nations Economic Commission for Europe (UNECE), as well as the relevant regulations established by the                              Central Commission for the Navigation of the Rhine (CCNR).

(5)In particular, Edition 2.3 of the Inland ECDIS Product Specification for Inland Electronic Navigational Charts (Inland ENCs)                              and Status of Presentation Library of UNECE Resolution 48 ‘Recommendation on electronic chart display and information system                              for inland navigation (Inland ECDIS)’ have been adopted by UNECE, following the recommendations of the Inland ENC Harmonization                              Group and the Inland ECDIS expert group.

(6)The technical specifications should also take due account of the work carried out by the expert group on Inland ECDIS which                              is composed of representatives of the authorities of the Member States responsible for the implementation of Inland ECDIS                              and official members from other governmental bodies as well as observers from the industry.

(7)The technical specifications should correspond to the current technical state of the art. Experiences gained from the application                              of Directive 2005/44/EC and the technical progress should be taken into account when establishing the technical specifications.                              The technical specifications should take due account of the work carried out by the expert group on Inland ECDIS as well as                              by UNECE and CCNR.

(8)The reference to UNECE standards in this Regulation does not create any precedent for future EU standards related to inland                              navigation, RIS and ECDIS. The Commission has indeed initiated an evaluation of the implementation of the RIS policy. The                              administrative arrangement between the Directorate-General for Mobility and Transport of the European Commission and CCNR                              may be extended to the elaboration of standards in the field of RIS, depending on the results of this evaluation, due to be                              available in 2014. Where such results are available the Commission should, if appropriate, amend accordingly this Regulation.

(9)In accordance with Article 12(2) of Directive 2005/44/EC, the Member States should take the necessary measures to comply with                              the requirements laid down in this Regulation not later than 30 months after its entry into force.

(10)The measures provided for in this Regulation are in accordance with the opinion of the Committee established pursuant to Article                              7 of Council Directive 91/672/EEC of 16 December 1991 on the reciprocal recognition of national boatmasters’ certificates                              for the carriage of goods and passengers by inland waterway(2).

(11)Article 12(2) of Directive 2005/44/EC foresees that the technical guidelines and specifications shall enter into force on                              the day following that of their publication in the *Official Journal of the European Union*,

Inland ECDIS aims to contribute to the safety and efficiency of inland shipping.                            

Inland ECDIS can be designed for both **information mode** and **navigation mode**, or for **information mode only**.                            

The minimum requirements for Inland ECDIS equipment designed for **information mode only**, specified in Chapter 4.1 of Section 1 and Section 4 of this Annex, are mandatory on waterways where carriage requirements                                 are enacted by the responsible legislative organs. In other regions they are recommended.                            

For **navigation mode** Inland ECDIS (Operating System Software, Application Software and Hardware) as specified in Section 4 of this Annex shall                                 have a high level of reliability and availability; at least of the same level as other means of navigation.                            

Inland ECDIS shall use chart information as specified by Sections 2 and 3 of this Annex.                            

National authorities and international bodies are recommended to consider transitional provisions when they are introducing                                 carriage requirements for Inland ECDIS.                            

Inland ECDIS shall meet all the requirements of the Inland ECDIS performance standard set out in this Annex.                            

The terms ‘skipper’ and ‘boat master’ used in this Annex shall be deemed to be equivalent with the term ‘ship master’ used in the RIS Guidelines – Commission Regulation (EC) No 414/2007 (3) .                            

The producer or supplier of Inland ECDIS software must document in the user manual of the software which requirements for                                 equipment (hardware) referred to in point (c) need to be fulfilled for Inland ECDIS in information mode on waterways where                                 carriage requirements are enacted by the responsible legislative organs.                            

When the Inland ECDIS equipment provides essential services as defined in Directive (EU) 2016/1148 concerning measures for                                 a high common level of security of network and information systems across the Union, the provisions of the said legislation                                 apply.

#### 4.PRESENTATION OF INFORMATIONU.K.

##### 4.1.**Display requirements**U.K.

The display method shall ensure that the displayed information is clearly visible to more than one observer in the typical                                 conditions of light experienced in the wheelhouse of a vessel by day and night.                            

In navigation mode the display size of the chart presentation shall be at least 270 mm by 270 mm for equipment designed and                                 admitted for the **navigation mode**.                            

In information mode ergonomic aspects shall determine the size. The information displayed must be readily visible from the                                 conning position.                            

The display diagonal shall be equal to or larger than 199 mm (7,85 inches). Under all conditions the boat master must be capable                                 of perceiving the displayed information sufficiently in accordance with Human Machine Interface guidelines.                            

If the software is sold without a display, the manufacturer's documentation shall include the information that it may only                                 be used as Inland ECDIS in information mode if the display fulfils the requirements of this Chapter 4.1.                            

The following criteria must be fulfilled in navigation mode as well as in information mode:                            
                -  Alphanumeric data and text shall be presented using a clearly legible non-italic sans-serif font.                                   
                -  The font size shall be appropriate for the viewing distance from user positions (i.e. with respect to reading distance and                                       viewing angles) likely to be experienced in the wheelhouse of a vessel.                                   
                -  The character height and the size of AIS symbols in millimetres shall not be less than 3,5 times the nominal viewing distance                                       in metres.                                   
                -  The minimum size of AIS symbols and the minimum character height of AIS information shall be 3,5 mm.                                   
                -  The manufacturer's documentation shall identify the nominal viewing distance for the display equipment.                                   

The display requirements shall be complied with, whether in landscape or in portrait format.                            

In information mode for the size of the display it is recommended to use the size as specified for navigation mode. In the                                 event that space for the installation of the display is a problem, the display size might be reduced taking into account the                                 nominal viewing distance for the display.                            

##### 4.2.**Display ranges (scales)**U.K.

In **information mode** (refer to Chapter 5.1 of this Section) all scales and ranges are permitted.                            

In **navigation mode** (refer to Chapter 5.2 of this Section), only the successive switchable ranges (scales) specified in Chapter 4.7 of Section                                 4 of this Annex are permitted.                            

##### 4.3.**Image positioning and orientation**U.K.

In **information mode** all kinds of chart orientation are permitted (see Chapter 5.1 of this Section)                            

In **navigation mode** the chart shall be automatically positioned and oriented in the relative motion, head-up orientation with the own vessel's                                 position in the screen centre or off-centred (see Chapter 5.2 of this Section).                            

##### 4.4.**Display of SENC information**U.K.

The display of SENC information shall be divided into the following three display categories:                            
                -  Display Base                                   
                -  Standard Display (Standard Information Density)                                   
                -  All Display.                                   

The allocation of the feature classes to the display categories is given in detail in the Look-up Tables of the document referred                                 to in point 2(i) of Section 1 of this Annex.                            

The Display Base category shall contain at least the following features:                            
                -  bank of waterway (at mean water level),                                   
                -  shoreline construction (e.g. groin, longitudinal control dam, training wall – any facility that is considered a hazard to                                       navigation),                                   
                -  contours of locks and dams,                                   
                -  boundaries of the fairway/navigation channel (if defined),                                   
                -  isolated dangers in the fairway/navigation channel under water,                                   
                -  isolated dangers in the fairway/navigation channel above water level, such as bridges, overhead wires etc.,                                   
                -  official aids-to-navigation (e.g. buoys, lights and beacons).                                   

The Standard Display (Standard Information Density) category shall contain at least the following features:                            
                -  the objects of Display Base category,                                   
                -  prohibited and restricted areas,                                   
                -  piers for commercial vessels (cargo and passenger),                                   
                -  kilometre and hectometre or mile marks on the banks.                                   

The All Display category shall display all features that are contained in the Inland SENC, individually on demand.                            

When starting the Inland ECDIS, it shall come up with the Standard Information Density as defined in the document referred                                 to in point 2(c) of Section 1 and the Glossary of Terms in Section 5 of this Annex.                            

Inland ECDIS shall be switchable to the Standard Information Density at any time by a single operator action.                            

Inland ECDIS shall clearly indicate the information density in use at all times.                            

Time variable depth information in the ENC shall be displayed independently of the three display categories referred to in                                 point (a).                            

##### 4.5.**Display of radar information**U.K.

In **navigation mode** the radar image shall have the highest display priority and shall only be permitted to be presented in the relative motion,                                 head-up mode. If the system is also type approved for maritime ECDIS, true motion and north-up mode may be implemented, but                                 only for working in **information mode**.                            

The underlaid SENC shall match in position, range and orientation. The radar image and the position from the position sensor                                 shall both be adjustable for the antenna offset to the conning position.                            

The overlaid radar image shall conform to the minimum requirements as specified in Chapter 4.14 of Section 4 of this Annex.                            

The overlaid radar image may contain additional navigational information. Any additional navigational information and tracking                                 and tracing symbols shall however in no way degrade the display of the original radar content.                            

##### 4.6.**Display of other navigational information**U.K.

Inland ECDIS and additional navigational information (Inland AIS) shall use a common conventional geodetic coordinate reference                                 system.                            

It shall be possible to display the skipper's own vessel's position on the screen.                            

It shall be possible for the skipper to select safety depth limits.                            

Inland ECDIS shall indicate the falling short of the safety depth limits.                            

##### 4.7.**Colours and symbols**U.K.

The display of colours and symbols to represent SENC information shall at least be able to comply with the regulations of                                 Section 3 of this Annex. Additionally other user-selectable symbol sets are permitted.                            

To present navigational elements and parameters as listed in the document referred to in point 2(d) of Section 1 of this Annex                                 other colours and symbols than those mentioned in point 4.7(a) of this Section shall be used.                            

##### 4.8.**Data and display accuracy**U.K.

The accuracy of the calculated data that are presented shall be independent of the display characteristics and shall be consistent                                 with the SENC accuracy.                            

The Inland ECDIS in **navigation mode** shall provide an indication as to whether the display uses a smaller display range than the accuracy of the Inland ENC data                                 offers (over-scale indication).                            

The accuracy of all calculations performed by Inland ECDIS shall be independent of the characteristics of the output device                                 and shall be consistent with the SENC accuracy.                            

Bearings and distances drawn on the display or those measured between features already drawn on the display shall have accuracy                                 no less than that afforded by the resolution of the display.                            

#### 5.OPERATIONU.K.

##### 5.1.**Information mode**U.K.

**Information mode** shall be used for information only and not for navigation.                            

In **information mode** all kinds of chart orientation, rotation, zooming and panning are allowed. However, it is recommended to use the same fixed                                 ranges as in the **navigation mode** and the chart orientation whether:                            
                -  to north, or                                   
                -  to the fairway axis at the actual position, or                                   
                -  to the actual vessels heading.                                   

It shall be possible to scroll the chart manually on the screen with the fairway axis in line with the vertical screen axis.                            

Inland ECDIS may be connected to a positioning sensor to scroll the chart picture automatically and to display the section                                 of chart matching the actual surrounding, namely in the operator-selected range.                            

Information regarding the position and orientation of other vessels, gathered by communication links like AIS, shall be only                                 displayed if they are up-to-date (nearly real-time) and accurate. If the heading of other vessels is not available, the position                                 and the orientation of those other vessels shall not be presented by:                            
                -  a directed triangle, or                                   
                -  a true outline (to scale).                                   

In this case the usage of a generic symbol is recommended.                            

The following time out values are recommended (from IEC 62388):                            

The AIS targets should be marked as outdated if the position information of moving vessels is older than 30 seconds.                            

Information on the intention (blue sign) or the number of blue cones of other vessels, the status of signals, weather warnings                                 (from Meteoalarm: www.meteoalarm.eu) and the water level received via Inland AIS may be displayed. The information on the                                 intention (blue sign) shall only be displayed on the right side of the symbol, if the heading of the vessel is available.                                 If no heading information is available the information shall only be displayed in a direction independent form.                            

The following table is providing an example for the display:                            

Information regarding AIS base stations, AIS Aids to Navigation (ATON) and AIS Search and Rescue Transmitters (SART) may be                                 displayed, if the symbols can be distinguished from other symbols (e.g. symbols 2.10 and 2.11 of IEC 62288 Ed. 2, Table A.2).                            

Information received by an AIS device and required by local police regulations shall be displayed.                            

It shall be possible to display all information transmitted by an AIS on user request.                            

##### 5.2.**Navigation mode**U.K.

In **navigation mode**, the Inland ECDIS display shall be integrated with the own vessel's radar information.                            

The radar information shall be clearly distinguishable from the SENC information.                            

The integrated display shall be in accordance with the requirements for radar on inland waterways as specified in Chapter                                 4.14 of Section 4 of this Annex.                            

The chart and the radar image shall match in size, position and orientation within the limits as specified in Chapters 3.4                                 and 8.3.2 of Section 4 of this Annex.                            

The integrated display shall only be presented in the head-up orientation. Other orientations are permitted in systems with                                 an additional maritime ECDIS type approval. If such a system is used in true motion and/or north-up mode on European inland                                 waterways, it is considered to be working in **information mode**.                            

It shall be possible for the operator to adjust the off-set values between the positions of the position sensor and the radar                                 antenna of the vessel so that the SENC display matches the radar image.                            

It shall be possible to temporarily remove either the ECDIS or the radar information by a single operator action.                            

The vessel's position shall be derived from a continuous positioning system, the accuracy of which is consistent with the                                 requirements of safe navigation.                            

**Navigation mode** shall provide an indication when the input from the position-fixing system is lost.                            

**Navigation mode** shall also repeat, but only as an indication, any alarm or indication passed to it from a position fixing system.                            

The positioning system and the SENC shall be based on the same geodetic datum.                            

In **navigation mode**, the data referred to in Chapter 3.1, point (c), first to seventh indent of this Section, and the following elements shall                                 always be visible and shall not be obscured by other objects:                            
                -  Headline line (as required by ETSI EN 302 194-1, see document referred to in Chapter 2, point (f) of Section 1)                                   
                -  Bearing line (as required by ETSI EN 302 194-1, see document referred to in Chapter 2, point (f) of Section 1)                                   
                -  Range rings (as required by ETSI EN 302 194-1, see document referred to in Chapter 2, point (f) of Section 1)                                   
                -  Navigation lines (as required by ETSI EN 302 194-1, see document referred to in Chapter 2, point (f) of Section 1)                                   
                -  P-Lines                                   
                -  Buoys                                   
                -  Inland AIS symbols                                   
                -  Inland AIS labels (if displayed)                                   
                -  AtoN information.                                   

The transparency of the radar overlay shall therefore be user defined. It shall be possible to switch Inland AIS labels off                                 either manually or on base of a configured timeout value.                            

Information regarding the position and orientation of other vessels, gathered by other communication links than the own radar,                                 may be displayed only if they are up-to-date (nearly real-time) and meet the accuracy that is required for the support of                                 tactical and operational navigation. Position information of the own vessel that is received from a repeater station shall                                 not be displayed.                            

As tracking and tracing information (for example AIS) of other vessels is useful for the planning of the passing, but of no                                 use during passing itself, tracking and tracing (AIS) symbols shall not disturb the radar image during passing and shall be                                 faded out therefore. Preferably the application shall allow the skipper to define the area where the symbol is faded out.                            

If the heading of other vessels is available, the position and the orientation of those other vessels may be presented by                            
                -  a directed triangle, or                                   
                -  a true outline (to scale).                                   

In all other cases a generic symbol shall be used (an octagon is recommended, a circle shall not be used for applications                                 which are certified according to maritime standards).                            

Information that another vessel is carrying blue cones or lights may be displayed by a different colour of the vessel symbol.                                 The number of the blue cones/lights shall only be displayed in the pick report.                            

Information on the intention of another vessel to pass on starboard (blue sign) may only be displayed on the right side of                                 the directed triangle symbol or of the scaled shape if the heading of this vessel is available. If no heading information                                 is available the information shall only be displayed in a direction independent form.                            

Information regarding the position of AIS base stations, AIS Aids to Navigation (ATON) and AIS Search and Rescue Transmitters                                 (SART) may be displayed, if the symbols can be distinguished from other symbols (e.g. symbols 2.10 and 2.11 of IEC 62288 Ed.                                 2, Table A.1).                            

##### 5.3.**Operation and control elements**U.K.

Inland ECDIS shall be designed having regard to ergonomic principles for user-friendly operation.                            

The Inland ECDIS equipment shall have a minimum of operation and control elements (see Section 4 of this Annex).                            

Operation and control elements, and indicators for connected sensors, may be integrated in Inland ECDIS.                            

Standard settings and user-defined settings shall be easily retrievable.                            

#### 6.CONNECTION WITH OTHER EQUIPMENTU.K.

Inland ECDIS shall not affect the performance of any connected equipment adversely. Similarly the connection of optional equipment                                 shall not degrade the performance of Inland ECDIS.                            

Inland ECDIS shall be capable of generating information to other systems, e.g. for the purpose of electronic reporting.                            

The relevant requirements of controls and indicators to connected equipment shall be fulfilled.                            

#### 7.INDICATIONS AND ALARMSU.K.

##### 7.1.**Built in Test Equipment (BITE)**U.K.

Inland ECDIS in navigation mode shall be provided with the means for carrying out on-board tests of major functions either                        automatically or manually. In case of a failure, the module at fault shall be shown.                   

##### 7.2.**Malfunctions**U.K.

#### 8.FALL-BACK ARRANGEMENTSU.K.

##### 8.1.**Insufficient accuracy of the SENC-positioning**U.K.

In **navigation mode** the SENC shall be automatically switched off, if the SENC positioning does not match the radar picture within the limits                        set out in Chapters 5.1 and 5.2 of Section 4 of this Annex.                   

##### 8.2.**Defects**U.K.

If the Inland ECDIS system in navigation mode has an evident defect, it shall provide a suitable alarm (refer to Chapters                                 4.16 and 9 of Section 4 of this Annex).                            

Facilities enabling a safe take-over of the functions of Inland ECDIS in navigation mode shall be provided in order to ensure                                 that an Inland ECDIS failure does not result in a critical situation.                            

#### 9.POWER SUPPLY IN NAVIGATION MODEU.K.

The Inland ECDIS shall have its own separate fused power supply.                   

### *SECTION 2*U.K.***DATA STANDARD FOR INLAND ENCs***

#### 1.INTRODUCTIONU.K.

The Data Standard for Inland ENCs describes the technical specifications to be used                            
                -  for the exchange of digital hydrographic data between national inland waterway authorities, and                                   
                -  for its distribution to manufacturers, skippers and other users.                                   

This Data Standard shall be used for the production of Inland ENCs and bathymetric Inland ENCs. The transfer and distribution                                 of Inland ENCs and bathymetric Inland ENCs shall take place in such a way that data integrity is ensured.                            

This Data Standard is based on the document referred to in point 2(a) of Section 1 (‘S-57’).                            

This Data Standard describes the necessary additions and clarifications to S-57 and the application of S-57 for the purpose                                 of use in Inland ECDIS applications.

#### 2.THEORETICAL DATA MODELU.K.

The description of the theoretical data model in Part 2 of S-57 shall apply to the theoretical data model of Inland ENCs and                        bathymetric Inland ENCs.                   

#### 3.DATA STRUCTUREU.K.

The description of the data structure in Part 3 of S-57 shall apply to the data structure of Inland ENCs and bathymetric Inland                        ENCs.                   

#### 4.PRODUCT SPECIFICATIONS FOR INLAND ENCs AND BATHYMETRIC INLAND ENCsU.K.

The Product Specifications for Inland ENCs and for bathymetric Inland ENCs enable chart producers to produce a consistent                        Inland ENC or bathymetric Inland ENC, and manufacturers to use that data efficiently in an Inland ECDIS that satisfies the                        Performance Standard for Inland ECDIS set out in Section 1.                   

Data for ENCs shall be made available to all manufacturers of applications. An Inland ENC shall be produced in accordance                        with the rules laid down in the document referred to in point 2(h) of Section 1 of this Annex and shall be encoded using the                        following documents referred to therein:                   

the Inland ENC Feature Catalogue and                            

the rules described in the Inland ENC Encoding Guide.                            

A bathymetric Inland ENC shall be produced in accordance with the rules laid down in the document referred to in point 2(j)                        of Section 1 of this Annex and shall be encoded using:                   

the bathymetric Inland ENC Feature Catalogue referred to in point 2(j) of Section 1 of this Annex and                            

the rules described in the Inland ENC Encoding Guide referred to in point 2(h) of Section 1 of this Annex                            

Inland ENCs and bathymetric Inland ENCs approved for navigation mode shall be produced in accordance with the ‘Data Standard’ and the ‘Product Specification’ referred to in this Section.                   

### *SECTION 2A*U.K.***CODES FOR PRODUCERS AND WATERWAYS (IN ADDITION TO IHO–S-62 ENC PRODUCER CODES***

Codes for producers of Inland ENCs as well as the registration procedure are those mentioned in the document referred to in                        point 2(b) of Section 1 of this Annex (‘IHO S-62’).                   

Administrations or private companies which produce Inland ENCs and which are not mentioned in IHO-S-62 and administrations                        or private companies which decide to produce Inland ENCs shall register a producer code at the S-100 registry of IHO at http://registry.iho.int                   

Since a producer code alone is not sufficient to establish whether an Inland ENC is appropriate to be used in navigation mode,                        the competent authorities referred to in Article 8 of Directive 2005/44/EC shall maintain and provide via their official website                        an up-to-date list of Inland ENCs approved for navigation mode within their geographical area of responsibility. The list                        shall include the file name of the ENC cell, the stretch of the inland waterway that is covered, the edition number, the issue                        date and a list of available update files to the currently valid edition also with their issue dates. The list shall include                        all Inland ENC for which the cell complies with the requirements as regards the minimum content and is approved for navigation                        mode.                   

The notification of competent authorities in accordance with Article 8 of Directive 2005/44/EC shall include information on                        the geographical area of responsibility and the official website of the competent authorities. Member States shall notify                        the Commission immediately of any changes.                   

The following Codes for Waterways shall be used in the file name of IENCs:                   

### *SECTION 3*U.K.***PRESENTATION STANDARD FOR INLAND ECDIS***

#### 1.INTRODUCTIONU.K.

This Presentation Standard for Inland ECDIS describes the technical specifications to be used for the presentation of Inland                                 ECDIS data. The presentation shall take place in such a way that none of the information is lost.                            

This Presentation Standard is based on the document referred to in point 2(c) of Section 1 (‘S-52’).                            

This Presentation Standard describes the necessary additions and clarifications to S-52 and the application of S-52 for the                                 purpose of use in Inland ECDIS applications.                            

The presentation of Inland ECDIS data shall meet the requirements of the Presentation Standard described in Section 3 and                                 the Presentation Library referred to in point 2(i) of Section 1.                            

Definitions of terms may be found in:                            
                -  Part 1, clause 5 of IHO-S-57,                                   
                -  the document referred to in point 2(g) of Section 1 of this Annex,                                   
                -  the ‘Glossary for Inland ECDIS’ in Section 5 of this Annex.                                   

#### 2.THE PRESENTATION LIBRARY FOR INLAND ECDISU.K.

S-57 data sets describe the data standard for Inland ENCs, however, they do not contain any information about how the data                        is going to be presented. The chart presentation is generated online in the Inland ECDIS application. For that purpose, the                        Inland ECDIS application uses machine-readable symbolisation instructions for each feature, which is drawn on the screen.                        For the presentation of ENCs the IHO S-52 standard is mandatory. The S-52 standard contains all rules which are necessary                        for the symbolisation and presentation of ENCs on the screen.                   

Since the features, attributes and attribute values for ENCs were extended for Inland ENCs and bathymetric Inland ENCs, an                        extension of the S-52 standard is necessary in order to be able to display also the Inland specific features. All extensions                        apply to the document referred to in the fourth indent of point 2(c) of Section 1 of this Annex.                   

##### 2.1.**Components of S-52 and Inland ECDIS Presentation Library**U.K.

###### 2.1.1.The major components of the S-52 presentation library are:U.K.

          -  a *library* of symbols, line styles and fill styles,                          
          -  a *colour coding scheme* which includes the IHO colour tables for day, dusk and night time,                          
          -  a *set of symbology command words* from which machine readable instructions can be assembled. The result is a symbology instruction, which is processed to symbolise                              ENC features in turn,                          
          -  a *set of conditional symbology procedures* to decide the appropriate symbolisation in cases determined by the mariner's selection (e.g. safety contour) or for complex                              symbols (e. g. top marks on buoys and beacons),                          
          -  a *set of look-up tables* that link feature descriptions from the ENC to the appropriate symbology instructions depending on whether:                          
          -  the link is straight forward, i.e. a direct relationship between a feature's description and its presentation such as a buoy                              or a land area. In this case, the look-up table provides the symbology *instruction* to show a symbol, an area fill, or a line style,                          
          -  the link is conditional, i.e. depending on circumstances, for example a depth area, whose colour fill depends on the choice                              of the safety contour. In this case the look-up table refers the decision to a *conditional symbology procedure* that selects the appropriate symbology instructions later.                          

###### 2.1.2.Inland ECDIS shall use all S-52 components plus extensions in:U.K.

          -  Lookup tables                          
          -  Symbol library                          
          -  Conditional symbology procedures.                          

The extensions are described in the document referred to in point 2(i) of Section 1.                   

##### 2.2.**Look-up tables**U.K.

###### 2.2.1.For each geometry type (point, line, area) there is a separate look-up table. Each entry in a look-up table consists of the                           following fields:U.K.

6-character code of the feature class (acronym);                            

Attribute combination;                            

Symbolisation instructions;                            

Display priority, 0-9 (comparable with drawing layers);                            

Radar code;                            

Display category (Display base, standard, all other);                            

‘Viewing group’, more refined grouping of features than the display categories.                            

###### *Figure 1***Example entry of a look-up table**U.K.

"LNDMRK","CATLMK17|","SY(TOWERS01)","7","O","OTHER","32250"                   

In this case the feature LNDMRK is shown by the symbol TOWERS01 with priority 7, if the attribute CATLMK equals 17. The feature                        lies over the radar.                   

The presentation of features in a specific area that are contained in different cells of the same usage follows the entries                        in the look-up tables.                   

###### 2.2.2.The Presentation Library provides five look-up tables:U.K.

          -  paper chart point symbols,                          
          -  simplified point symbols,                          
          -  line symbols,                          
          -  plain area boundary symbols,                          
          -  symbolised area boundary symbols.                          

##### 2.3.**Conditional symbology procedures (CS)**U.K.

CS procedures shall be generated for features of which the symbolisation                   
          -  depends on application settings, e.g. safety contour,                          
          -  depends on other features, e.g. top marks and their structure,                          
          -  is too complex to be defined in a direct look-up table entry.                          

CS procedures, which shall be modified or implemented in an Inland ECDIS additional to the CS procedures of S-52 are described                        in the document referred to in point 2(i) of Section 1.                   

##### 2.4.**Colours**U.K.

Colours used in an ECDIS are defined in an absolute manner, independently from the monitor used (using CIE coordinates). This                        ensures that ECDIS charts look similar on monitors of different suppliers. CIE values are converted into RGB values by means                        of colour calibration software which must be used by the manufacturer.                   

Commercial displays usual in the trade are seen as matching those requirements.                   

Due to the fact that various light conditions might occur on the bridge of a vessel, it is necessary to offer presentations                        with different brightness levels. For each level a separate colour table exists.                   

The represented colour scheme shall be chosen on the basis of ergonomical and physiological factors and the representation                        of indications in different colours shall not result in mixed colours by superimposing.                   

##### 2.5.**Presentation of notice marks**U.K.

Notice marks which are located at the river bank are presented in the chart displayed by generic symbols (notmrk01, notmrk02                        and notmrk03). This does not apply to the notice marks on bridges.                   

Additionally, applications are required to be able to display the detailed symbol, which is similar to the real world indication,                        and the full set of object information of a user-selected notice mark.                   

Notice marks that are located at bridges, shall be symbolised according to the orientation of the bridge.                   

Notice marks which specify distances or a velocity shall not be symbolised with the number itself, but only with that symbol                        which gives the general regulation or information.                   

### *SECTION 4*U.K.***OPERATIONAL AND PERFORMANCE REQUIREMENTS, METHODS OF TESTING AND REQUIRED TEST RESULTS***

#### 1.INTRODUCTIONU.K.

This Section specifies the minimum requirements contained in Section 1 of this Annex and describes the test procedures and                        the required results concerning the hardware, the software, the functions, the operation, the display and the interfaces to                        other equipment on board of vessels.                   

#### 2.OPERATING MODES AND SYSTEM CONFIGURATIONU.K.

##### 2.1.**Operating modes**U.K.

The Inland ECDIS technical specifications distinguish two operating modes: **navigation mode** and **information mode**.                            

Inland ECDIS equipment designed for operating in **navigation mode** shall fulfil the requirements of this Annex and the standards on navigational radar equipment and rate-of-turn indicators. For                                 Inland ECDIS in navigation mode a type approval is required by competent authorities referred to in point 2(q) of Section                                 1.                            

For Inland ECDIS equipment designed for **information mode** only, the requirements of this Section 4 are to be understood as technical (operational and performance) requirements. The                                 producer has to document the conformity with these technical requirements. A type approval is not required for Inland ECDIS                                 in information mode. The documentation shall be made available to competent authorities and users on request.                            

##### 2.2.**System configurations**U.K.

###### 2.2.1.*System configuration 1: Inland ECDIS equipment, stand-alone-system without connection to radar*U.K.

In this system configuration only operation in **information mode** is possible (see Section 4B, Figure 1).                   

###### 2.2.2.*System configuration 2: Inland ECDIS equipment, parallel installation and connection to radar*U.K.

###### 2.2.3.*System configuration 3: Inland ECDIS equipment, monitor shared with connected radar equipment*U.K.

In this system configuration, the monitor of the radar equipment is shared with the Inland ECDIS equipment. Prerequisite for                        this mode are matching graphic parameters for both video signals and a video switch, which allows a fast switchover of the                        video sources (see Section 4B, Figure 3).                   

This system configuration allows operation in **information mode** as well as in **navigation mode**.                   

###### 2.2.4.*System configuration 4: Radar equipment with integrated Inland ECDIS functionality*U.K.

This system configuration is a radar installation with integrated Inland ECDIS functionality that can be operated in information                        mode as well as in **navigation mode** (see Section 4B, Fig. 4).                   

#### 3.PERFORMANCE REQUIREMENTSU.K.

##### 3.1.**Hardware performance**U.K.

Inland ECDIS in navigation mode equipment shall be designed and manufactured to withstand typical environmental conditions                                 prevailing on board of a vessel without any degradation in quality and reliability. Furthermore, it shall not disturb other                                 communication and navigation equipment.                            

In the configuration as described in Chapter 2.2.4 of this Section, all components of Inland ECDIS equipment installed inside                                 the wheelhouse shall fulfil the requirements of the class b) ‘protected from weather’ equipment as specified in the standard EN 60945 with the exception that the test temperature range is limited to 0 °C to                                 + 40 °C (whereas the test temperature range in EN 60945 is specified from – 15 °C to + 55 °C) unless specified differently                                 in this Annex. For the configurations described in Chapters 2.2.2 and 2.2.3 of this Section CE conformity is sufficient.                            

##### 3.2.**Software performance**U.K.

Software for the operation, visualisation, and functionality of Inland ECDIS equipment shall be designed, developed, implemented,                        and tested in accordance with the software requirements described in Section 4A to this Annex.                   

##### 3.3.**Performance of operation controls**U.K.

The operation of the system shall be simple, appropriate and conform to common human interface standards. The operational                                 state of the system and the connected technical sub devices has to be clearly indicated.                            

The number of operational controls shall be as low as possible and restricted to the required number.                            

Wireless remote controls are not permitted.                            

The ON/OFF switch shall perform and shall be arranged in such a way that inadvertent operation is not possible.                            

The symbols of the operating controls shall have a minimum character height of 4 mm and shall be readable under all conditions                                 that may exist in a wheelhouse.                            

The brilliance and the illumination of the operating controls shall be adjustable to the required value.                            

##### 3.4.**Display performance**U.K.

The provisions of Chapters 3.4.2 to 3.4.7 are recommended for Inland ECDIS in information mode.                   

###### 3.4.1.*Display dimensions*U.K.

In **navigation mode** the minimum chart and radar display area shall be at least 270 mm by 270 mm.                            

In information mode the requirements of point 4.1(c) of Section 1 shall be applicable.                            

###### 3.4.2.*Display orientation*U.K.

A rectangular display may be mounted in landscape or in portrait orientation under the prerequisite that the minimum dimensions                                 set out in Section 3.4.1 are fulfilled.                            

Because of the limited space available in the typical wheelhouse of an inland vessel and the fact that a vessel usually follows                                 the fairway-axis, the display shall be installed preferably in the portrait orientation.                            

###### 3.4.3.*Display resolution*U.K.

A display resolution of 5 m in the 1 200 m range is required. This leads to a maximum pixel dimension of 2,5 m × 2,5 m, i.e. about 1 000 pixels at the short edge of the display.                   

###### 3.4.4.*Display colours*U.K.

The system shall be able to display ergonomically proven colour combinations for day and night.                   

###### 3.4.5.*Display brilliance*U.K.

The brilliance of the display shall be adjustable to every operational required value. This is especially valid for the lowest                        value during operation at night.                   

###### 3.4.6.*Picture renewal*U.K.

The picture renewal rate shall not be shorter than that of the radar picture (≥ 24 pictures per minute).                            

Between two consecutive renewals no fluctuations of brilliance shall occur.                            

On raster scan displays, the frame repetition rate shall not be lower than 60 Hz.                            

###### 3.4.7.*Display technology*U.K.

Display systems that are insensitive to the magnetic fields that may occur in the wheelhouse of an inland vessel shall be                        used.                   

#### 4.OPERATIONAL FUNCTIONSU.K.

##### 4.1.**Operating mode**U.K.

If the equipment is able to work in both operation modes it shall provide for the possibility of switching between **navigation mode** and **information mode**.                            

The operation mode in use shall be displayed.                            

Suitable measures are required to prevent the inadvertent switching off of the **navigation mode**.                            

##### 4.2.**Equipment pre-sets (store/recall) in navigation mode**U.K.

After starting the Inland ECDIS equipment shall come up with a moderate brilliance pre-set which neither blinds in a dark                                 environment nor makes the picture invisible in a bright environment.                            

Other parameters may come up with their values at the time before switching off or from stored settings.                            

##### 4.3.**Presentation of SENC information in navigation mode**U.K.

The radar picture shall be clearly distinguishable from the chart independent of the chosen colour table.                            

Only a monochrome presentation of the actual radar picture is permitted.                            

The presentation of chart information shall not mask or degrade important parts of the radar picture. This shall be ensured                                 by appropriate entries into the look-up tables (refer to Section 3 of this Annex, Chapter 2.2, field ‘radar code’). The transparency of the radar overlay shall therefore be user-defined.                            

Chart and radar picture presentation shall have the same scale.                            

The heading line shall be always visible.                            

Additionally, the mariner's own vessel's contour and the safety contours may be inserted.                            

##### 4.4.**Chart orientation, positioning and shifting**U.K.

In **navigation mode**, only the chart orientation ‘relative motion, head up’ and the ‘centred’ or ‘off centred’ presentations, as required for the radar picture, are permitted.                            

In **information mode**, at least the chart orientations ‘north’ and ‘parallel to the waterway axis’ as well as positioning are recommended. By connection of a positioning sensor, the displayed part of the chart can automatically                                 follow the mariner's own vessel's position.                            

##### 4.5.**Position and bearing of the own vessel**U.K.

In **navigation mode**, the own vessel's position shall always be visible in the display area, whether ‘centred’ or ‘off centred’ as specified in the document referred to in point 2(f) of Section 1.                            

In **navigation mode** the heading line, which runs from the display centre to the top and which shall be always visible, shall represent the heading                                 of the mariner's own vessel.                            

##### 4.6.**Information density**U.K.

The information density shall be at least adjustable to the three switch steps: ‘Base’, ‘Standard’ and ‘All Information’. The latter displays all other features in addition to the ‘Standard’ display, individually on demand. All corresponding visible features are defined in the ‘Performance Standard’ and the ‘Presentation Standard’ (incl. the ‘Presentation Library for Inland ECDIS’) (Sections 1 and 3 of this Annex).                   

##### 4.7.**Ranges/Range rings**U.K.

In **navigation mode** the following fixed ranges and range rings are prescribed according to the radar regulations:                            

Smaller and larger ranges with a minimum of four and a maximum of six range rings are permitted.                            

Inland ECDIS equipment in **navigation mode** shall have fixed range rings with the intervals set out in points (a) and (b) and at least one variable range marker (VRM).                            

Switching on/off of fixed and variable range markers shall be independent of each other and their display shall be clearly                                 distinguishable.                            

The position of the VRM and the corresponding displayed distance shall use the same increments and resolution.                            

The functions of the VRM and the electronic bearing line (EBL) may additionally be realised by a cursor and by a corresponding                                 numerical display, showing range and bearing of the cursor position.                            

##### 4.8.**Picture brilliance in navigation mode**U.K.

The brightness of the display shall be adjustable to the operationally necessary value. This applies in particular to operation                                 in darkness.                            

Chart and radar picture shall have separate brightness controls.                            

Because of the strongly different environment brightness of bright day and dark night, another control for the basic brightness                                 of the display shall be available additionally to the colour tables in the menu.                            

##### 4.9.**Picture colours**U.K.

At least the colour combinations included in the IHO-S-52 Presentation Library,6.0 (colour tables) for day, dusk and night                        shall be supported.                   

##### 4.10.**Pick report**U.K.

It shall be possible to get all underlying textual and/or graphical information concerning user selections of the features                                 that are displayed in the chart.                            

This additional textual and/or graphical information shall not hamper the view of the waterway in the navigational chart.                            

##### 4.11.**Measuring features**U.K.

Measuring features for distances and bearings are required.                            

Resolution and accuracy shall at least be the same as those of the display, but may not suggest better values than those of                                 the chart data.                            

##### 4.12.**Input and editing of skippers' own chart entries**U.K.

Inland ECDIS equipment shall allow input, storing, modifying and deletion of additional chart information by the skipper (skippers'                                 own features) in navigation mode as well as in information mode.                            

These own chart entries shall be distinguishable from the SENC data, and shall not overlay or degrade the radar picture in                                 navigation mode.                            

##### 4.13.**Loading and updating of SENCs**U.K.

All **manual** activities concerning loading or updating of charts shall be possible only outside the **navigation mode**.                            

**Automatic** updating shall not downgrade the performance of the navigation display.                            

A rollback function shall be implemented to allow restoring to the last working combination.                            

##### 4.14.**Radar picture presentation and overlay**U.K.

The radar image representation is mandatory for operation in the **navigation mode**.                            

The dimensions, resolution and attributes of the radar presentation shall fulfil the relevant radar requirements.                            

The radar picture shall not be degraded by other contents of the picture (see also point 4.3(c) of this Section).                            

Provided the functional requirements are fulfilled, overlaying of different information layers is permitted.                            

The overlay of information regarding the position and orientation of other vessels is only allowed when:                            
                -  the information is up-to-date (real-time), and                                   
                -  the age of information does not exceed the maximum time out values provided in the first table in point 5.1(e) of Section                                       1. The symbols shall be marked as outdated, if the age of the information exceeds 30 seconds for moving vessels. The position                                       information of the own vessel shall only be displayed when the position is detected by an on board subsystem and not if the                                       position is received from a repeater station.                                   

The overlaid information derived from tracking and tracing devices regarding the position and orientation of other vessels                                 shall be faded out at a user-definable range. The activation of this feature and the selected range of the restricted area                                 shall be indicated on the display.                            

Only if the heading of other vessels is available, the position and the orientation of those other vessels may be presented                                 by:                            
                -  a directed triangle, or                                   
                -  a true outline (to scale).                                   

In all other cases a generic symbol shall be used (an octagon is recommended, a circle shall be used for inland applications                                 only).                            

It shall be possible to switch off the chart and any other information layer and to display only the radar picture by one                                 easily accessible control element or menu area.                            

If the quality and plausibility monitoring of the Inland ECDIS equipment detect that the chart cannot be oriented and/or positioned                                 with the accuracy required by this Annex, an alarm shall be presented on the display and the chart shall be switched off automatically.                                 If there is no radar signal, the information mode shall be displayed. In both cases a warning or an alarm shall be given.                                 The switching shall always be possible by manual action.                            

##### 4.15.**Inland ECDIS functions with immediate access**U.K.

These functions shall have either own control elements or own menu areas, which are arranged in the highest menu level and                                 are permanently visible.                            

##### 4.16.**Permanently visible function parameters**U.K.

The following function parameters shall always be visible:                   
          -  actual RANGE                          
          -  sensor STATUS (in **navigation mode**: radar tuning, position quality, alarms; in **information mode**: if connected, GNSS receiver, AIS and heading)                          
          -  selected WATER LEVEL (if available)                          
          -  selected SAFETY DEPTH (if available)                          
          -  selected INFORMATION DENSITY                          

#### 5.SERVICE FUNCTIONSU.K.

Service functions shall be protected by password or other suitable measures against unauthorised access. They shall not be                        selectable in **navigation mode**.                   

The requirements of Chapters 5.1 to 5.3 are only applicable to **navigation mode**.                   

##### 5.1.**Static correction of the chart position**U.K.

The position of the mariner's own vessel shall be presented ‘centred’ or ‘off centred’ on the display in accordance with the radar requirements. The chart position shall match the radar image. Assuming an absolute                                 position's input the permissible static difference between actual radar position and displayed radar centre shall not exceed                                 1 m.                            

It shall be possible to correct an offset error (distance between the positions of the position sensor and the radar sensor).                            

##### 5.2.**Static correction of the chart orientation**U.K.

#### 3.CHANGES TO CERTIFIED NAVIGATION SYSTEMSU.K.

##### 3.1.**General requirements**U.K.

Navigation systems installed on board shall be functionally equivalent to a system certified by authorities. For every system                        the navigation system provider shall ship a statement of compliance with the Inland ECDIS technical specifications and its                        functional equivalence to the certified system.                   

The competent authority is entitled to check Inland ECDIS compliance of installed systems at any time.                   

##### 3.2.**Hardware and software changes**U.K.

The navigation system provider may change software or hardware as long as Inland ECDIS compliance is maintained. Changes shall                        be fully documented and submitted to the competent authority, together with an explanation of how the navigation system is                        affected by those changes. The competent authority may require a partial or complete renewal of certification if considered                        necessary. The aforementioned also applies to the use of an approved Inland ECDIS with another national version of the operating                        system.                   

The following changes do not affect certification of the system and require only a notice to the competent authority:                   
          -  minor changes on third party components (e.g. operation system or library updates),                          
          -  use of equivalent or better hardware components (e.g. faster microprocessor, newer chip revisions, equivalent graphic card,                              etc.),                          
          -  minor changes in source code or documentation.
