What key function does the ECDIS perform regarding navigation hazards?

• A. It alerts the crew when hazards are identified
• B. It automatically adjusts the vessel's course away from hazards
• C. It marks hazards visually on the chart display
• D. It ignores hazards below a certain threshold

Answer: (C)

The key function of the ECDIS in relation to navigation hazards is to visually mark hazards on the chart display. This capability is crucial for enhancing situational awareness, allowing the crew to identify potential dangers in the navigational area quickly and effectively. The visual representation of hazards helps mariners make informed decisions to avoid these dangers while navigating, improving overall safety at sea. By incorporating detailed hazard information on electronic charts, ECDIS provides real-time updates and integrates data from various sources, including radar and AIS (Automatic Identification System). This visual marking is crucial, as it not only shows the location and nature of hazards but can also provide additional information such as depth of water in relation to the hazards, allowing for dynamic and adaptive navigation strategies. The other choices suggest functions that are not accurate or do not align with the primary purpose of ECDIS. For instance, while the system can provide alerts for hazards, it does not automatically take action such as adjusting the vessel’s course, nor does it ignore hazards based on a threshold. Therefore, the ability to visually display hazards on the chart is a defining trait of ECDIS functionality in navigation safety.
