Medical Emergency — PAN & Priority Landing

What this scenario covers

1. Exchange 1

   Declare the urgency: PAN PAN ×3, station, callsign and the nature of the emergency.

   💡 A serious but not immediately life-threatening medical case is an urgency — "PAN PAN" ×3. (A patient in extremis may warrant MAYDAY.) Either way ATC will give priority; state the nature clearly.

2. Exchange 2

   State your request: priority approach, an ambulance to meet the aircraft, and pass persons on board.

   💡 Ask for the specific resources you need — a priority approach AND medical assistance (ambulance/paramedics) to a defined point (the gate/stand). Persons on board helps ground services plan.

3. Exchange 3

   ATC: “American Two Three One, Chicago Center, roger, descend and maintain one one thousand, turn left heading two seven zero, vectors for the visual runway two eight right, expedite descent.”

   Read back the expedited descent and the vector. Level and heading are mandatory.

   💡 Read back both the assigned level and the heading — the two items ATC most needs confirmed. Acknowledging "expedite" tells the controller you understand the urgency of the descent.

4. Exchange 4

   ATC: “American Two Three One, squawk seven seven zero zero, contact Chicago Approach one two five point three five.”

   Read back the squawk and the frequency change.

   💡 Squawk and frequency changes are both mandatory readbacks. In the US the decimal is spoken "point"; read the frequency back in full before leaving the current one.
