What indication occurs when a route is planned over a ship's safety contour?

• A. No indication occurs
• B. An indication is required
• C. The navigation system shuts down
• D. The vessel is immediately redirected

Answer: (B)

When a route is planned over a ship's safety contour, the Electronic Chart Display and Information System (ECDIS) is designed to provide warnings or indications to the navigator. This is essential for maintaining safe navigation and avoiding grounding. The safety contour is a defined depth that indicates the lowest point at which a vessel can safely navigate without the risk of hitting the seabed. If a planned route crosses or sits within the safety contour zone, an indication is required to inform the navigator that the route might lead to unsafe waters. This feature is a critical component of ECDIS as it assists in risk management and helps ensure that navigators are made aware of potential dangers in real-time, allowing for necessary adjustments to the planned route before proceeding. While the other options suggest scenarios like no indication, system shutdowns, or immediate redirection, these actions do not align with the operational protocols of ECDIS concerning safety contours. The system's primary function is to enhance navigation safety through appropriate warnings rather than to disable itself or forcibly alter routes without navigator input.
