Appendix 3 - Logical Grouping of Information

 Introduction

1 This appendix defines groups of related navigational information that should be displayed together on the user interface, to enable the user to quickly locate and react to essential navigation information, if available on the screen. This appendix applies to radar equipment, ECDIS and minimum INS functions as defined in resolution MSC.252(83). It may be applied to other electronic navigation equipment and navigation sensors where applicable, to improve standardization and usability.

2 This appendix does not specify where the groups of information should appear on the screen, or the order in which the individual information elements should be grouped. The groups of related navigational information presented on the user interface are not limited to the information listed in this appendix. They may be extended by associated information. These groupings apply to both mandatory and non-mandatory information.
