Add a new paragraph 1.9
-
1.9 When the relevant chart information is not available in the appropriate
form (see section 4), some ECDIS equipment may operate in the Raster Chart
Display System (RCDS) mode as defined in Appendix 7. Unless otherwise
specified in Appendix 7, the RCDS mode of operation should conform to
performance standards not inferior to those set out in this Annex.
Modify paragraph 10.5.7 as follows:
-
10.5.7 ECDIS should provide an alarm when the input from the position-fixing
system is lost. ECDIS should also repeat, but only as an indication, any
alarm or indication passed to it from a position-fixing system.
In Appendix 5, paragraph 10.5.7 change the word "indication" to "alarm".
Add a new Appendix 7 to the Annex to the resolution:
APPENDIX 7 - RCDS MODE OF OPERATION
Whenever in this appendix a reference is made to provisions of the Annex related to
ECDIS, ECDIS should be substituted by RCDS, SENC by SRNC and ENC by RNC, as
appropriate.
All paragraphs of the Annex related to ECDIS are indicated as to whether they apply
to RCDS, do not apply to RCDS, or are modified in order to apply to RCDS. These
paragraphs are followed by additional requirements for ECDIS equipment in the RCDS
mode.
1 INTRODUCTION
1.1 Paragraph applies to RCDS.
1.2 When operating in the RCDS mode, ECDIS equipment should be used together with an
appropriate portfolio of up-to-date paper charts.
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).
2 DEFINITIONS
2.1 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.
2.2 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.
2.3 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.
2.4-2.5 Paragraphs do not apply to RCDS.
2.6 Paragraph applies to RCDS.
3 DISPLAY OF SRNC INFORMATION
3.1 Paragraph applies to RCDS.
3.2 SRNC information available for display during route planning and route monitoring
should be subdivided into two categories:
-
.1 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
-
.2 any other information such as mariner's notes.
3.3 Paragraph applies to RCDS.
3.4 When a RNC is displayed on the RCDS, it should provide an indication advising the
mariner if a more detailed (larger scale) RNC is available for the displayed
area.
3.5 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.
3.6-3.7 Paragraphs do not apply to RCDS.
3.8-3.10 Paragraphs apply to RCDS.
3.11 There should always be an indication if the ECDIS equipment is operating in the
RCDS mode.
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 meta-data (i.e.,
additional data) to allow georeferenced 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.
4.3-4.8 All paragraphs apply to RCDS.
5 SCALE
This section applies to RCDS.
6 DISPLAY OF OTHER NAVIGATIONAL INFORMATION
6.1-6.3 All paragraphs apply to RCDS.
7 DISPLAY MODE AND GENERATION OF THE NEIGHBOURING AREA
7.1 It should always be possible to display the RNC in "chart-up" orientation. Other
orientations are permitted.
7.2-7.4 All paragraphs apply to RCDS.
8 COLOURS AND SYMBOLS
8.1 IHO recommended colours and symbols should be used to represent SRNC
information.
8.2 Paragraph applies to RCDS.
8.3 Paragraph does not apply to RCDS.
8.4 Paragraph applies to RCDS.
9 DISPLAY REQUIREMENTS
9.1-9.2 Paragraphs apply to RCDS.
9.3 Paragraph does not apply to RCDS.
9.4 Paragraph applies to RCDS.
9.5 RCDS should be capable of displaying, simply and quickly, chart notes which are
not located on the portion of the chart currently being displayed.
10 ROUTE PLANNING, MONITORING AND VOYAGE RECORDING
10.1-10.2 Paragraphs apply to RCDS.
10.3 Paragraph does not apply to RCDS.
10.4 Route Planning
10.4.1-10.4.3 Paragraphs apply to RCDS.
10.4.4-10.4.5 Paragraphs do not apply to RCDS.
10.4.6 Paragraph applies to RCDS.
10.4.7 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.
10.5 Route monitoring
10.5.1 Paragraph applies to RCDS.
10.5.2 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.
10.5.3-10.5.4 Paragraphs do not apply to RCDS.
10.5.5-10.5.8 Paragraphs apply to RCDS.
10.5.9 The RCDS should only accept data referenced to the WGS-84 or PE-90 geodetic
datums. RCDS should give an alarm if the positional data is not referenced to one of
these datums.
10.5.10-10.5.13 Paragraphs apply to RCDS.
10.5.14 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.
10.5.15 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.
10.6 Voyage recording
10.6.1-10.6.4 All paragraphs apply to RCDS.
11 ACCURACY
11.1-11.2 All paragraphs apply to RCDS.
12 CONNECTIONS WITH OTHER EQUIPMENT
12.1-12.2 All paragraphs apply to RCDS.
13 PERFORMANCE TESTS, MALFUNCTION ALARMS AND INDICATIONS
13.1-13.2 All paragraphs apply to RCDS.
14 BACK-UP ARRANGEMENTS
15 POWER SUPPLY
15.1-15.2 All paragraphs apply to RCDS.
