What is the exact Emergency Descent PA used on the flight deck?

• A. Attention passengers! Immediate descent.
• B. Attention crew! Initiate rapid descent.
• C. Attention cabin crew! Emergency Descent.
• D. Attention cabin crew! Verify oxygen masks.

Answer: (C)

In an emergency, clear, direct communication to the right people is crucial. The exact phrase used to start the rapid descent is designed to rapidly mobilize the cabin crew to begin the procedure. "Attention cabin crew! Emergency Descent." does exactly that: it names the audience (cabin crew) and the action (Emergency Descent) in a concise, unambiguous way, so everyone knows to initiate the descent immediately.

The other options either target passengers, use less precise wording, or refer to actions that aren’t the command to start the descent (for example, addressing passengers or stating verification of oxygen masks). This is why the chosen phrasing is the correct one for initiating the emergency descent.
