🔍 Key Concepts

• Radiotelephone distress, urgency, and safety signals hierarchy (Mayday / Pan-Pan / Securite) • Purpose of the safety signal (type of messages it is used for) • Standard radio procedure words and repetition used on VHF

💭 Think About

• First, match each standard word (Mayday, Pan-Pan, Securite) with its level: distress, urgency, or safety. Which one corresponds to safety? • Think about how these procedure words are normally spoken on the radio: do we say the key word once or three times at the start of the call? • Compare the answer choices: which one uses the correct word for a safety message and the correct number of repetitions?

✅ Before You Answer

• Verify which signal is used for distress (life in immediate danger) versus urgency (urgent but not life-threatening) versus safety (navigational or meteorological warnings). • Check that the correct French-origin word is being used for safety-related information broadcasts. • Confirm that standard radiotelephone procedure calls for the safety signal word to be repeated three times at the beginning of the transmission.
