A Ch-70 DSC Distress alert is received. What action should be taken?
⢠DSC (Digital Selective Calling) Distress alerts on VHF Ch-70 and the required followâup on voice channel 16 ⢠Role of all ships in range when a Distress alert is received (GMDSS obligations) ⢠Difference between acknowledging to the ship and listening/relaying for the Rescue Coordination Center (RCC)
⢠After a Ch-70 DSC Distress alert sounds on your set, what voice channel is associated with that alert, and why is listening there important? ⢠In a real emergency, which is more important initially: immediately talking back to the vessel, or making sure you correctly monitor and understand the distress traffic? ⢠Should an ordinary ship normally send a DSC âreceiptâ back to the distress vessel, or is that function primarily for coast stations / RCC under GMDSS procedures?
⢠Verify what standard followâup channel is used after a VHF Ch-70 DSC Distress alert (think: routine distress working channel). ⢠Check whether all ships that receive the alert must maintain watch and be ready to assist, not just coast stations. ⢠Confirm who is normally authorized to acknowledge a DSC distress alert by DSC (ship vs. coast station) before deciding whether to transmit anything.
