💭 Think About

• Ask yourself: which word is used when there is an urgent situation that is not yet life‑threatening, but still needs prompt attention? • Which of these signals is reserved only for situations where there is grave and imminent danger to life or the vessel? • Which of these options is actually used to start or end a period of radio silence, rather than declare a distress or urgency situation?

✅ Before You Answer

• Be sure you can define distress, urgency, and safety calls and match each to its spoken signal • Identify which term is associated with navigational or weather safety information broadcasts • Confirm which term is used by the controlling station to cancel radio silence after a distress situation is over
