DISPLAY ANOMALIES IN SOME ECDIS.
A number of ECDIS operating anomalies have been identified, including the discovery that some models of some ECDIS equipment might
not, under certain circumstances, display all navigationally significant features or activate appropriate alarms. Due to the complex nature of
ECDIS, and in particular because it involves a mix of hardware, software and data, it is possible that further anomalies may exist.
The two documents identified below contain comprehensive explanations of the types of anomalies which might be encountered, along with
advice and guidance on remedial action.
All mariners are advised to obtain both of these two documents direct from their respective web sites:
1. The International Maritime Organization (IMO) Circular SN.1/Circ.312 available at -
http://www.imo.org/OURWORK/CIRCULARS/PAGES/IMODOCS.aspx (registration required).
2. United Kingdom Marine Information Note (MIN) 445 (M+F) available at - http://www.dft.gov.uk/mca/mcga07home/newsandpublications/mcga-publications.htm
(registration not required). This document also contains IMO Circular SN.1/Circ.312 at its
Annexes.
All mariners are also strongly encouraged to use the IHO check dataset which is designed to highlight those ECDIS that are unable to
display the IMO approved chart features and those that may show the anomalous display and alarm behaviour. A copy of the IHO check
dataset is included as part of the Admiralty Vector Chart Service product to help the mariner.
