What happens upon receiving a DSC Distress alert on 8414.5 kHz?

Upon receiving a DSC Distress alert on 8414.5 kHz, a series of actions typically occurs to ensure a rapid response to the emergency situation. The DSC controller is designed to enhance situational awareness and facilitate immediate action.

When a Distress alert is received, the controller emits both audible and visual alarms. This dual alert system is critical in ensuring that the crew is made immediately aware of the emergency, allowing them to take necessary actions without delay.

Furthermore, the particulars of the alert, which include vital information such as the identity of the vessel in distress, the nature of the distress, and location data, may be printed out. This printed information can be crucial for keeping a record of the alert and can also assist responding vessels or shore stations in making informed decisions quickly.

Additionally, the distress information is often sent to the data directory, which can help streamline communication and coordination among vessels and rescue services in the area, ensuring that assistance is dispatched promptly.

All of these actions—emission of audible and visual alarms, printing of the alert particulars, and transmission of the data to the directory—are part of a comprehensive response to a Distress alert, making a coordinated response possible. Thus, the correct answer encompasses all these critical functions
