4 Provision and Updating footnote of Chart Informatin

  4.1 The chart information to be used in ECDIS should be the latest edition of information originated by a government-authorized hydrographic office, and conform to IHO standards.

  4.2 The contents of the SENC should be adequate and up-to-date for the intended voyage, as required by regulation V/20 of the 1974 SOLAS Convention.

  4.3 It should not be possible to alter the contents of the ENC.

  4.4 Updates should be stored separately from the ENC.

  4.5 ECDIS should be capable of accepting official updates to the ENC data provided in conformity with IHO standards. These updates should be automatically applied to the SENC. By whatever means updates are received, the implementation procedure should not interfere with the display in use.

  4.6 ECDIS should also be capable of accepting updates to the ENC data entered manually with simple means for verification prior to the final acceptance of the data. They should be distinguishable on the display from ENC information and its official updates, and not affect display legibility.

  4.7 ECDIS should keep a record of updates, including time of application to the SENC.

  4.8 ECDIS should allow the mariner to display updates so that the mariner may review their contents and ascertain that they have been included in the SENC.
