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.
1.1 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).
2.1 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 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.
4.3–4.8 All paragraphs apply to RCDS.
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.
8.1 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.
9.1–9.2 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.
10.4.1-10.4.3 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.
10.5.1 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.
10.6.1-10.6.4 All paragraphs apply to RCDS.
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.
All paragraphs apply to RCDS.
15.1-15.2 All paragraphs apply to RCDS.
