Distress, urgency, or routine? Decide the priority, prowords, and call structure before you key up.
Build a quick mental checklist so the correct format and language are automatic when the pressure is on.
- Priority check: Distress (MAYDAY), Urgency (PAN-PAN), Safety (SÉCURITÉ), or Routine.
- Prowords refresher: “This is…”, repeats, “Over”, “Out”, confirmations.
- Order your message: who you’re calling, who you are, position, problem, people, intentions.
