🔍 Key Concepts

• Structure of a radiotelephone distress call and message under GMDSS/Radio regulations • Difference between the initial distress call (getting attention) and the distress message (details of the emergency) • What information must be included to allow effective search and rescue (SAR) response

💭 Think About

• Look at each choice and ask: does this describe the calling format, the message content, or something else? • Think about what a rescue authority or nearby ship absolutely needs to know right away to find you and help you. • Consider whether a complete distress procedure would reasonably include only one of these elements, a combination, or all that are listed.

✅ Before You Answer

• For the distress call, verify the standard spoken words and repetition requirements (how many times you say "MAYDAY" and the vessel ID). • For the distress message, verify if you must state position, nature of distress, and type of assistance required. • Check whether radio procedures usually combine the call format and the message content into a single correct answer, or separate them.
