Description

Part One explains how ECDIS operators can interpret and apply safety settings. Key safety settings covered include display configurations, safety contour and depth, shallow and deep contours, isolated danger, detection area/safety frame, and route check/cross track distance (XTD).

Part Two focuses on calculating and effectively managing Under Keel Clearance (UKC) aboard ships. A UKC plan ensures that safety settings can be easily reviewed at any point during the voyage.

Part Three provides worked examples to highlight the limitations of ENCs concerning safety settings. Each scenario illustrates different tidal calculations and their impact on ECDIS safety settings.
