Which action signals an emergency to the Flight Deck on the A330?

• A. Push PRIO CAPT
• B. INTPH+ALL
• C. Hold PPT bar
• D. PA+ALL

Answer: (A)

In an emergency, you need the flight deck’s attention immediately, so the signal must be direct and high priority. Pressing the PRIO CAPT control is a dedicated cabin-to-flight-deck alert that delivers a priority call specifically to the Captain’s line. It bypasses regular interphone traffic and standard announcements, ensuring the Captain is alerted first and most quickly. Other options either broadcast more generally (to all or to cabin speakers) or use standard interphone or push-to-talk functions that don’t guarantee immediate, cockpit-focused attention. Those paths can be slower or less urgent, which is not suitable for emergencies. So, the action that signals an emergency to the Flight Deck most effectively is pushing PRIO CAPT.
