Which of the following values are selected by the navigator for route monitoring in ECDIS?

• A. Safety contour, Echo soundings, and GPS correction
• B. Safety contour, XTD, and Chart Scale
• C. Waypoints, Anchorages, and Safety depth
• D. Chart Scale, Safety depth, and Weather conditions

Answer: (B)

The correct choice involves the values that a navigator selects for effectively monitoring a route in an ECDIS. The selected values include safety contour, cross-track distance (XTD), and chart scale. Safety contour is crucial as it represents the depth limit below which the chart does not provide depth information, helping the navigator avoid grounding when determining safe navigation routes. Cross-track distance (XTD) helps to determine how far the vessel is from the intended track, which is essential for monitoring deviations from the planned route and ensuring navigational safety. Chart scale denotes the level of detail and area covered by the electronic chart being used, allowing navigators to ascertain the resolution of the displayed information and make appropriate navigation decisions. While the other choices include relevant navigational concepts, they do not encapsulate the specific values related to route monitoring in ECDIS as comprehensively as the correct option does. For instance, waypoints and anchorages pertain to specific locations rather than the parameters necessary for real-time route assessment and monitoring.
