Sequence of updating my transas ecdis
Changes introduced in Edition 4.0 of the IHO ECDIS Presentation Library invalidate the tests contained in the ECDIS Data Presentation and Performance Checks published in 2011 which were specifically designed and developed for ECDIS using previous editions of the Presentation Library.
An ECDIS type approval certificate showing conformance with tests in Edition 4.0 of IEC 61174 demonstrates that the ECDIS operates with Edition 4.0 of the IHO ECDIS Presentation Library and therefore that the ECDIS does not have any of the identified ENC display anomalies.
Simply buy the licences to unlock the charts needed for a voyage, when and for as long as they are needed.
Most ENC-issuing countries allow durations of 3, 6, 9 or 12 months. All ECDIS equipment must undergo a type-approval certification process to ensure it meets IMO Performance Standards for ECDIS.
A re-run is recommended only after a software update, system upgrade or change of equipment.
The ADMIRALTY Vector Chart Service (AVCS) is the world’s leading digital maritime chart service, with over 15,750 official Electronic Navigational Charts (ENCs) to help bridge crews navigate safely and efficiently whilst meeting flag and port State requirements.
AVCS is delivered in industry standard S-63 / S-57 formats, guaranteeing compatibility with all type-approved ECDIS sold today.It contains ADMIRALTY Temporary and Preliminary Notices to Mariners (T&P NMs) and ENC Preliminary Notices to Mariners (EP NMs) which highlight navigationally significant differences between ENCs and ADMIRALTY paper charts.
