A Rationale for Future Bridge Navigation Displays A new IMO initiative

摘要

In July 2000, the International Maritime Organisation (IMO) at its NAV46 meeting agreed to a new work item 'to harmonize the presentation of navigation information' in such a way as 'to avoid confusion in the display of such information'[1]. This paper aims to give a brief review of some of the issues that need to be addressed, especially in the area of distributed information and clutter and to propose a means for moving forward in a coordinated effort to solve the anticipated problems. It is suggested that common integrated displays (also known as multi-function displays) with data fusion - rather than confusion - is perhaps the best way forward. Such common displays should be duplicated (or triplicated) and should all be 'Navigation and Hazard displays' that give effective 'situation awareness' and 'decision aid' support to the mariner. They should be individually selectable for the prevailing scenario and inclusive of all operational needs, both for the displayed information and what is displayed where. The selection of the presented information should be filtered by the 'need to know principle' to enable the user to reduce cognitive workload. It is further strongly recommended that an Internationally agreed 'common display surface' to the user be defined in both operation and symbology, irrespective of manufacturer. This is considered to be the only safe way forward particularly with predicted future manning levels. The mariner should be party to agreeing such an interface. A regulatory impact assessment should be carried out so that all stakeholders, including those involved in training, are better, informed of the benefits and risks.
