Electronic chart display and information system for inland navigation (Inland ECDIS) is composed of hardware, software for the operating system and application software.

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 ( 1 ).

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.

AIS is an automatic identification system for maritime vessels that complies with the technical and performance standards laid down in Chapter V of the SOLAS Convention (Safety of Life at Sea), as defined in the document referred to in point 2(r) of Section 1. Inland AIS refers to the automatic identification system for inland waterway vessels as set out in the document referred to in point 2(p) of Section 1. In this Annex, whenever AIS is mentioned it refers to both maritime AIS and Inland AIS, unless specified otherwise.

Directive 2002/59/EC establishing a Community vessel traffic monitoring and information system (OJ L 208, 5.8.2002, p. 10).

The chart information to be used in Inland ECDIS shall be the latest edition of information.

Provisions shall be made to prevent the user from altering the contents of original Inland ENC and bathymetric Inland ENC editions.

At least the following features shall be included in the ENC:

If the chart producer is using overlay files or bathymetric Inland ENCs, the features may be included in different chart cells, but the whole package must fulfil the minimum requirements listed in the indents above.

Where the chart is intended to be used for navigation mode (Chapter 5.2 of this Section), the respective competent authority shall decide for each waterway or harbour which of the features referred to in point (c) are to be verified. After verification, the respective competent authority shall declare which Inland ENCs and bathymetric Inland ENCs are approved for navigation mode within its geographical area of responsibility (for details see Section 2A of this Annex).

The System Electronic Navigational Chart (SENC) shall be stored in the Inland ECDIS.

Inland ECDIS shall be capable of accepting updates to the Inland ENC data provided in conformity with the Product Specification for Inland ENCs and updates of the depth information provided in conformity with the Product Specification for bathymetric Inland ENCs. Those updates shall be applied to the SENC automatically. The implementation procedure of the update shall not interfere with the display in use.

Inland ECDIS shall allow for the display of updates, so that the skipper may review their contents and ascertain that they have been included in the SENC.

Inland ECDIS shall be capable of revoking automatically applied updates of the Inland ENC data.

Original Inland ENC editions and later updates shall never be merged.

The Inland ENC and all updates to it shall be displayed without any degradation of their information content.

The Inland ENC data and updates to it shall be clearly distinguishable from other information.

Inland ECDIS shall ensure that the Inland ENC and all updates to it have been correctly loaded into the SENC.

Inland ECDIS shall keep a record of updates, including the time of application to the SENC.

The contents of the SENC to be used shall be adequate and up-to-date for the intended voyage.

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:

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.

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.

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).

The display of SENC information shall be divided into the following three display categories:

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:

The Standard Display (Standard Information Density) category shall contain at least the following features:

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).

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.

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.

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.

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.

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:

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:

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.

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:

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

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).

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.

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.

Inland ECDIS in navigation mode shall provide a suitable alarm or indication of system malfunctions (refer to Chapter 9 of Section 4 of this Annex).

Inland ECDIS in information mode shall provide a suitable alarm or indication of missing input from – if connected – GNSS receiver, AIS and heading device.

Inland ECDIS shall provide appropriate alarms or indications of malfunction of the equipment with respect to the displayed information

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.

The Data Standard for Inland ENCs describes the technical specifications to be used

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.

The Data Standard shall be compliant to standards and regulations indicated in points 2(h) and (j) of Section 1.

the Inland ENC Feature Catalogue and

the rules described in the Inland ENC Encoding Guide.

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

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:

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 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:

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.

The following operational functions require direct access:

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

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).

The difference between the heading line orientation and the vessel's axis shall not be greater than ± 1,0 degree.

Chart and radar image shall have the same orientation. The static directional error between heading line and chart orientation shall be less than ± 0,5 degree.

It shall be possible to configure interfaces for connected sensors, actors and signals.

Interfaces shall comply with existing interface specifications as defined in the document referred to in point 2(l) of Section 1 and the interface specifications for rate of turn indicators (20 mV/deg/min) as defined in the document referred to in point 2(d) of Section 1.

The test shall consist of a comparison between the Equipment Under Test (EUT) and the requirements of this Annex.

Proved equivalent tests, and proved and documented test results shall be accepted without renewed tests.

The entire Chapter 6 is valid for navigation mode, but the requirements that do not contain a specific reference to navigation mode are also valid for information mode.

Inland ECDIS equipment, as described in Chapter 2.2.4 of this Section, shall fulfil the requirements of the document referred to in point 2(k) of Section 1 concerning the resistance to environmental conditions (humidity, vibration and temperature; the latter reduced according to Chapter 3.1 of this Section) and concerning electromagnetic compatibility.

The provider or his representative shall submit a relevant conformity declaration of an accredited laboratory.

All interfaces shall be documented correctly and completely.

Electronic circuits shall be designed failsafe, mechanically as well as electronically, and shall not have degrading repercussions on connected equipment.

Whether the SCAMIN functionality (the minimum scale at which the feature may be used for ECDIS presentation) is installed correctly shall be tested.

For this test, the range shall be used at which the feature shall be visible according to its SCAMIN enumeration (refer to Chapter 8.4 of the document referred to in point 2(h) of Section 1).

All numeric displayed values of the electronic bearing line (EBL) and the variable range marker (VRM) shall exactly match with the analogue positions of the EBL and the VRM (or correspond with the cursor coordinates).

The resolution and increments of the numerical display shall be identical with the analogue values of EBL and VRM.

It shall be tested whether all features included in the test SENC and in the additional overlay test SENC are visible and correctly displayed. For this test the information density shall be switched to ‘all features’.

It shall be tested whether it is possible to select one or more specific cells for presentation if there are several cells from different producers for the same area with the same usage.

It shall be tested whether the test bathymetric Inland ENC is displayed correctly together with the base SENC in accordance with Chapter 6 of the document referred to in point 2(i) of Section 1.

For the test purposes, the manufacturer or provider shall provide a serial interface at the system to be approved (Equipment under test — EUT) which delivers the same actual values (as strings compliant with the document referred to in point 2(l) of Section 1) of position and heading that are used to position and orient the chart.

During the test, a reference system shall be used of which position and heading values are compared with those of the EUT.

The EUT shall be connected to any type approved radar equipment (to the choice of the provider).

The radar picture shall be adjusted in range and bearing with reference to the heading line.

If the Inland ECDIS equipment displays the radar picture but the radar operation control remains at the radar equipment (See Figures 2 and 3 of Section 4B), the radar picture of the inland ECDIS equipment shall be considered as the ‘daughter display’ of an item of radar equipment. In that case, the radar picture shall fulfil the display and picture-relevant requirements of the requirements for radar and rate-of-turn indicators as defined in the document referred to in point 2(f) of Section 1.

If the EUT is a radar installation with integrated Inland ECDIS functionality (See Figure 4 of Section 4B), all requirements of the standards for radar equipment and rate-of-turn indicators as defined in the document referred to in point 2(f) of Section 1 shall be fulfilled.

The radar image shall not be degraded by the chart picture (refer to point 4.3(c) of this Section).

The overlay of information regarding the position and orientation of other vessels shall be only displayed when:

The overlay of 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.

If the heading of other vessels is available, the position and the orientation of those other vessels shall be displayed by:

For all other vessels 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.

The chart picture shall be renewed not later than the radar picture.

The static offset of the chart position shall be less than ± 5 m in all ranges up to 2 000 m.

The static azimuth orientation offset error between radar and chart image shall be less than ± 0,5 degree.

The correction of the parameters referred to in points (a) and (b) shall be demonstrated in the service mode.

The dynamic deviation of the chart orientation at rates of turn less than ± 60 degree/min shall be less than ± 3 degree.

These tests shall be performed visually or by evaluation of measured data.

The alarms generated from Inland ECDIS equipment itself as well as the passed alarms delivered to the ECDIS by the connected sensors shall be tested.

The test procedure in navigation mode shall comprise the following situations:

The test procedure in information mode shall comprise the following situations:

This test shall demonstrate the reaction of the Inland ECDIS equipment to a failure of any internal or external component and the possible and required actions by the operator.

In addition, the operating manual shall be checked to determine whether the measures required by the operator are described adequately and appropriately.

The average position estimation shall not deviate more than 5 meters from the true position and shall cover all systematic errors.

The standard deviation σ shall be less than 5 meters and shall be based on random errors only.

The system shall be capable to detect deviations of more than 3σ within 30 seconds.
