This publication equips navigators with a thorough knowledge of ECDIS, contributing towards safer navigation and a more effective bridge team. It encourages operators to practise using every function and technique available on ECDIS, such as new automatic functions for creating ‘no-go’ alarms, 3D ENC functionality and ECDIS safety settings. A revised introduction chapter details the latest IMO Performance Standards for ECDIS equipment. The 2026 edition contains a new dedicated chapter on Port State Control, Audits and Inspections, alongside expanded S-100 ECDIS content and additional case studies examining incidents where incorrect ECDIS safety settings were a contributing factor. The verification checks are split according to ECDIS and Passage Planning verification, with the latter following the APEM structure. Each area of inspection is covered, with guidance included on how to conduct the checks. Updated ECDIS screenshots, expanded NAVTEX content and illustrations (such as the PSC flowchart) aid the reader’s understanding of best practice techniques.
