DSC controller is used to initiate distress alerts and calls to which destinations?

• A. Weather services
• B. Individual stations
• C. Shore stations only
• D. All ships at sea

Answer: (B)

DSC uses unique MMSI addresses to route distress and call signals. The main purpose of the DSC controller in an emergency is to reach a specific destination quickly and directly, such as an individual vessel or a particular coast station, by selecting its MMSI. This targeted approach ensures a rapid, traceable contact for coordinating rescue or assistance. Weather services are provided through other systems (like NAVTEX or satellite weather broadcasts), not by placing a DSC distress call to a weather service. Calling only shore stations or broadcasting to all ships in the area are possible DSC functions, but the standard, most effective use in a distress situation is to alert a specific station or vessel with its MMSI.
