Question 1 of 27070

Which of the following has been designated for “On-scene” communications in GMDSS?

🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) channel purposes (distress alerting, DSC, on‑scene coordination) • Differences between calling/distress channels and working/on‑scene channels • The specific role of VHF Channel 16 and VHF Channel 70 under GMDSS

💭 Think About

• For an ongoing SAR (search and rescue) operation, after the initial distress alert, what channel would units actually use to coordinate actions and pass voice traffic? • Which of the listed channels is used for DSC (Digital Selective Calling) rather than voice communications? • Which channels are primarily for initial distress/calling, and which are designated as working/on‑scene frequencies once contact is established?

✅ Before You Answer

• Identify which option is the DSC channel under GMDSS and eliminate it for on‑scene voice use. • Confirm which channel is designated for initial calling and distress alerts and consider whether that is normally kept clear or used for lengthy on‑scene coordination. • Think about which channel SAR units (ships, aircraft, rescue boats) would switch to after making initial contact to avoid blocking distress/calling traffic.
