RCDS MODE OF OPERATION
Whenever in this appendix reference is made to any provisions of
the annex related to ECDIS, the term ECDIS should be substituted by the term RCDS,
SENC by SRNC and ENC by RNC, as appropriate.
This appendix refers
to each paragraph of the performance standards for ECDIS (i.e. the Annex to which
this part is appendix 7) and specifies which paragraphs of the Annex either:
- apply to RCDS; or
- do not apply to RCDS; or
- are modified or replaced as shown in order to apply to RCDS.
Any additional requirements applicable to RCDS are also
Paragraph applies to RCDS.
1.2 When operating in
RCDS-mode, an appropriate portfolio of up-to-date paper charts (APC) should be
carried on board and be readily available to the mariner.
1.3 - 1.7 Paragraphs apply to RCDS.
1.8 RCDS should provide appropriate alarms or
indications with respect to the information displayed or malfunction of the
equipment (see Table 1 of this appendix).
1.9 Refers to Appendix 7 and applies to RCDS.
2 APPLICATION OF THESE STANDARDS
2.1 - 2.4 Paragraphs apply to RCDS.
3.1 Raster Chart Display System (RCDS) means a navigation
information system displaying RNCs with positional information from navigation
sensors to assist the mariner in route planning and route monitoring, and if
required, display additional navigation-related information.
3.2 Raster Navigational Chart (RNC) means a
facsimile of a paper chart originated by, or distributed on the authority of, a
government-authorized hydrographic office. RNC is used in these standards to mean
either a single chart or a collection of charts.
3.3 System Raster Navigational Chart Database
(SRNC) means a database resulting from the transformation of the RNC by the RCDS
to include updates to the RNC by appropriate means.
3.4-3.5 Paragraphs do not apply to RCDS.
3.6 Paragraph applies to RCDS.
3.7 Appropriate Portfolio of up to date paper
Charts (APC) means a suite of paper charts of a scale to show sufficient detail of
topography, depths, navigational hazards, aids to navigation, charted routes, and
routeing measures to provide the mariner with information on the overall
navigational environment. The APC should provide adequate look-ahead capability.
Coastal States will provide details of the charts which meet the requirement of
this portfolio, and these details are included in a worldwide database maintained
by the IHO. Consideration should be given to the details contained in this
database when determining the content of the APC.
MODULE A - DATABASE
4 PROVISION AND UPDATING OF CHART INFORMATION
4.1 The RNC used in RCDS should be the latest
edition of that originated by, or distributed on the authority of, a government
authorized hydrographic office and conform to IHO standards. RNCs not on WGS 84 or
PE-90 should carry metadata (i.e., additional data) to allow geo-referenced
positional data to be displayed in the correct relationship to SRNC data.
4.2 The contents of the SRNC should be adequate
and up-to-date for that part of the intended voyage not covered by ENC.
4.3 It should not be possible to alter the
contents of the RNC.
4.4 - 4.8 All paragraphs apply to RCDS.
4.9 Paragraph does not apply to RCDS
MODULE B - OPERATIONAL AND FUNCTIONAL REQUIREMENTS
5 DISPLAY OF SRNC INFORMATION
5.1 RCDS should be capable of displaying all SRNC
information. 5.2 SRNC information available for display during route planning and
route monitoring should be subdivided into two categories:
- the RCDS standard display consisting of RNC and its updates,
including its scale, the scale at which it is displayed, its horizontal datum,
and its units of depths and heights; and
- any other information such as mariner"s notes. MSC
5.3- 5.4 Paragraphs apply to RCDS.
5.5 It should be easy to add to, or remove from;
the RCDS display any information additional to the RNC data, such as mariner’s
notes. It should not be possible to remove any information from the RNC.
5.6 - 5.9 Paragraphs do not apply to RCDS.
5.10 - 5.12 Paragraphs apply to RCDS.
5.13 There should always be an indication if the
ECDIS equipment is operating in RCDS mode.
This section applies to
7 DISPLAY OF OTHER NAVIGATIONAL INFORMATION
7.1 - 7.4 All paragraphs apply to RCDS.
8 DISPLAY MODE AND GENERATION OF THE NEIGHBOURING AREA
8.1 It should always be possible to display the
SRNC in "chart-up" orientation. Other orientations are permitted.
8.2 - 8.4 All paragraphs apply to RCDS.
8.5 Paragraph refers to RCDS mode of operation.
9 COLOURS AND SYMBOLS
9.1 IHO recommended colours and symbols should be used to
represent SRNC information.
applies to RCDS.
9.3 Paragraph does not apply to
RCDS. 9.4 Paragraph applies to RCDS.
10 DISPLAY REQUIREMENTS
10.1-10.2 Paragraphs apply to RCDS.
10.3 Paragraph does not apply to RCDS. MSC
10.4 Paragraph applies to RCDS.
10.5 Paragraph does not apply to RCDS. 10.6 RCDS
should be capable of displaying, simply and quickly, chart notes which are not
located on the portion of the chart currently being displayed.
11 ROUTE PLANNING, MONITORING AND VOYAGE RECORDING
11.1 Paragraphs apply to RCDS.
11.2 Paragraph does not apply to RCDS.
11.3 Route Planning
11.3.1-11.3.3 Paragraphs apply to RCDS.
11.3.4-11.3.5 Paragraphs do not apply to RCDS.
11.3.6 Paragraph applies to RCDS.
11.3.7 It should be possible for the mariner to
enter points, lines and areas which activate an automatic alarm. The display of
these features should not degrade the SRNC information and it should be clearly
distinguishable from the SRNC information.
11.4 Route monitoring
11.4.1 Paragraph applies to RCDS.
11.4.2 It should be possible to display a sea area that does
not have the ship on the display (e.g. for look ahead, route planning), while
route monitoring. If this is done on the display used for route monitoring, the
automatic route monitoring functions in 10.4.6 and 10.4.7 should be continuous. It
should be possible to return to the route monitoring display covering own ship’s
position immediately by single operator action.
11.4.3-11.4.4 Paragraphs do not apply to RCDS.
11.4.5 Paragraph apply to RCDS.

11.4.7-11.4.9 Paragraphs apply to RCDS.
11.4.10 The RCDS should only accept positional
data referenced to the WGS 84 or PE-90 geodetic datum. RCDS should give an alarm
if the positional data is not referenced to one of these datum. If the displayed
RNC cannot be referenced to the WGS 84 or PE-90 datum then a continuous indication
should be provided. MSC
Paragraphs apply to RCDS.
11.4.16 RCDS should allow the user to manually
align the SRNC with positional data. This can be necessary, for example, to
compensate for local charting errors.
11.4.17 It should be possible to activate an
automatic alarm when the ship crosses a point, line, or is within the boundary of
a mariner entered feature within a specified time or distance.
