(f) Inland ECDIS shall be switchable to the Standard Information Density at any time by a single operator action. (g) Inland ECDIS shall clearly indicate the information density in use at all times. (h) Time variable depth information in the ENC shall be displayed independently of the three display categories referred to in point (a).
(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 ininformation mode .(b) 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. (c) The overlaid radar image shall conform to the minimum requirements as specified in Chapter 4.14 of Section 4 of this Annex. (d) 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.
(a) Inland ECDIS and additional navigational information (Inland AIS) shall use a common conventional geodetic coordinate reference system. (b) It shall be possible to display the skipper's own vessel's position on the screen. (c) It shall be possible for the skipper to select safety depth limits. (d) Inland ECDIS shall indicate the falling short of the safety depth limits.
(a) 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. (b) 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.
(a) The accuracy of the calculated data that are presented shall be independent of the display characteristics and shall be consistent with the SENC accuracy. (b) 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).(c) 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. (d) 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.
(a) Information mode shall be used for information only and not for navigation.(b) 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 thenavigation mode and the chart orientation whether:to north, or to the fairway axis at the actual position, or to the actual vessels heading.
(c) It shall be possible to scroll the chart manually on the screen with the fairway axis in line with the vertical screen axis. (d) 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. (e) 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): Category of vessel Nominal reporting interval Maximum time out value Nominal reporting interval Maximum time out value class A class A class B class B Vessel at anchor or moored and not moving faster than 3 knots (class B not moving faster than 2 knots) 3 min 18 min 3 min 18 min Vessel at anchor or moored and moving at more than 3 knots 10 s 60 s 3 min 18 min Vessel operating in SOLAS mode, moving 0 to 14 knots 10 s 60 s 30 s 180 s Vessel operating in SOLAS mode, moving 0 to 14 knots and changing course 3 1/3 s 60 s 30 s 180 s Vessel operating in SOLAS mode, moving 14 to 23 knots 6 s 36 s 30 s 180 s Vessel operating in SOLAS mode, moving 14 to 23 knots and changing course 2 s 36 s 30 s 180 s Vessel operating in SOLAS mode, moving faster than 23 knots 2 s 30 s 30 s 180 s Vessel operating in SOLAS mode, moving faster than 23 knots and changing course 2 s 30 s 30 s 180 s Vessel operating in inland waterway mode 2 – 10 s 60 s — — 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: Visualisation of Blue Sign status 0 to 2 and dangerous goods Blue sign Not connected or not available Not Set Set Blue cones no 1 to 3 no 1 to 3 no 1 to 3 Heading No Symbol 
Yes Symbol 
True shape 
(f) 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). (g) Information received by an AIS device and required by local police regulations shall be displayed. (h) It shall be possible to display all information transmitted by an AIS on user request.
(a) 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. (b) 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. (c) 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. (d) 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 .(e) 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. (f) It shall be possible to temporarily remove either the ECDIS or the radar information by a single operator action. (g) The vessel's position shall be derived from a continuous positioning system, the accuracy of which is consistent with the requirements of safe navigation. (h) 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.(i) The positioning system and the SENC shall be based on the same geodetic datum. (j) 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. (k) 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. (l) 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. (m) 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). (n) 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. (o) 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. (p) 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).
(a) Inland ECDIS shall be designed having regard to ergonomic principles for user-friendly operation. (b) The Inland ECDIS equipment shall have a minimum of operation and control elements (see Section 4 of this Annex). (c) Operation and control elements, and indicators for connected sensors, may be integrated in Inland ECDIS. (d) Standard settings and user-defined settings shall be easily retrievable.
(a) 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. (b) Inland ECDIS shall be capable of generating information to other systems, e.g. for the purpose of electronic reporting. (c) The relevant requirements of controls and indicators to connected equipment shall be fulfilled.
(a) 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).(b) Inland ECDIS in information mode shall provide a suitable alarm or indication of missing input from – if connected – GNSS receiver, AIS and heading device.(c) Inland ECDIS shall provide appropriate alarms or indications of malfunction of the equipment with respect to the displayed information
(a) 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). (b) 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.
(a) 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.
(b) 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.

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.
