|
|
The absence of a charted AtoN is indicated using |
|
|
yellow caution colour for both the basic diamond |
|
|
part of the symbol and for text "Missing". The basic |
AIS AtoN indicating the |
|
diamond part is always empty without symbol of |
absence of a charted |

the type of the AtoN. |

|
Note: This case is communicated as a combined |
|
|
state of "Virtual" and "off position". Type of absent |
|
|
AtoN can be determined be the underlying charted |
|
|
object, or selecting the Virtual AIS AtoN Object. |

ANNEX 2
GUIDELINES FOR THE PRESENTATION OF NAVIGATION-RELATED
TERMS AND ABBREVIATIONS
1 Purpose
The purpose of these Guidelines is to provide guidance on the use of appropriate navigation-related terminology and abbreviations intended for presentation on shipborne navigational displays. These are based on terms and abbreviations used in existing navigation references.
2 Scope
These Guidelines are issued to ensure that the terms and abbreviations used for the display of navigation-related information on all shipborne navigation equipment and systems are consistent and uniform.
3 Application
3.1These Guidelines apply to all shipborne navigational systems and equipment including radar, ECDIS, AIS, INS and IBS. When navigation-related information is displayed as text, the standard terms or abbreviations listed in the appendix should be used, instead of using terms and abbreviations which are currently contained in existing performance standards.
3.2Where a standard term and abbreviation is not available, another term or abbreviation may be used. This term or abbreviation should not conflict with the standard terms or abbreviations listed in the appendix and provide a clear meaning. Standard marine terminology should be used for this purpose. When the meaning is not clear from its context, the term should not be abbreviated.
3.3Unless otherwise specified, standard terms should be shown in lower case while abbreviations should be presented using upper case.
