Module B - Operational and Functional Requirements

Parent topic: Appendix 7 - RCDS Mode of Operations

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:

  • .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 mariners notes.

  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.

6 Scale

 This section applies to RCDS.

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.

  9.2 Paragraph 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.

  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.

  11.4.6 Paragraphs do not 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.

  11.4.11-11.4.15 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.

11.5 Voyage recording

  11.5.1-11.5.4 All paragraphs apply to RCDS.

12 Calculations and Accuracy

  12.1–12.3 All paragraphs apply to RCDS.

  12.4 RCDS should be capable of performing transformations between a local datum and WGS 84 Datum.

13 Performance Tests, Malfunction Alarms and Indications

  13.1-13.2 All paragraphs apply to RCDS.

14 Back-up Arrangements

 All paragraphs apply to RCDS.
