All ECDIS should have been upgraded to the new IHO S-52 Presentation Library edition 4.0 by August 31st 2017.
IMO SN Circ 266 rev1 states;
ECDIS that is not updated for the latest version of IHO Standards may not meet the chart carriage requirements as set out in SOLAS regulation V/19.2.1.4.
Once upgraded there is no need to use the IHO Check Data Set to check that symbols are being displayed correctly.
To check that the ECDIS is correctly displaying the new symbols, the Mariner can check ECDIS Chart 1. ECDIS Chart 1 is a legend of the entire set of symbols that may be used within an ENC. It is installed on all type approved ECDIS systems.
Only ECDIS updated to IHO Presentation Library edition 4.0 will be able to show the new ENC symbols.
