The International Hydrographic Organization (IHO) has updated the Data Protection Scheme for ENCs to Edition 1.2, but there is no change to the format of data or permits.
In response to customers who have asked whether AVCS is compliant with the latest standard, the DVDs and CDs will shortly be updated to state 'S-63 Edition 1.2'. The media boxes will follow at the next reprint shortly afterwards.
Although there is a new version of the scheme, AVCS S-63 Edition 1.1 is fully compatible with Edition 1.2 and is still fully compliant with all regulations.
A compliance statement can be found in the document 'Important information for AVCS users', published on the ADMIRALTY website.
