Q

Which radiotelephone transmission may be sent over channel 16?

🔍 Key Concepts

• VHF Channel 16 purpose (calling and distress safety frequency) • Difference between distress/urgency/safety traffic and working traffic • Which types of messages must be brief calls vs. which must be shifted to a working channel

💭 Think About

• Think about why Channel 16 is monitored continuously by many vessels and coast stations. Which kinds of messages need to be heard by everyone? • Ask yourself which of these transmissions is a full conversation and which is just an initial call or alert before shifting to another channel. • Consider whether on‑scene SAR coordination is usually done on 16 or shifted to a different channel after contact is made.

✅ Before You Answer

• Verify the primary, internationally assigned functions of VHF Channel 16 under GMDSS and traditional VHF rules. • Check which items in the list are initial alerts/calls versus ongoing working communications. • Confirm which traffic is supposed to be transferred to a working channel once contact is established.
