🔍 Key Concepts

• Radiotelephone distress, urgency, and safety calls (Mayday, Pan-Pan, Securite) • Priority order of radiotelephone calls under GMDSS (Global Maritime Distress and Safety System) • Difference between distress, urgency, and safety of navigation messages

💭 Think About

• First, recall which spoken word corresponds to a life-threatening distress situation and immediate assistance, and eliminate that option. • Then, think about whether "Securite" is more closely connected with danger to a specific ship, or with general safety information for all vessels in an area. • Ask yourself: when you hear "Securite" three times, what type of information do you expect to hear next—navigation hazards, weather warnings, or a request for help?

✅ Before You Answer

• Verify which call has highest priority and is used only for immediate danger to life or vessel. • Confirm which call word is associated with urgent but not immediately life‑threatening situations. • Identify which call word is used to preface navigational or meteorological warnings intended for all ships in an area.
