When the Captain's NORM/EMER on the Audio Control Panel is selected to EMER, what happens?

• A. The Captain's headset is automatically selected to Nav 1 and VHF 1
• B. The Captain's headset is muted
• C. The Intercom is silenced
• D. The First Officer's headset is selected

Answer: (A)

In EMER mode, priority is given to the captain’s communications. When the Captain’s NORM/EMER control is set to EMER, the system automatically routes the captain’s headset to the primary radios—Nav 1 and VHF 1—so the captain can hear and transmit on those channels directly. This ensures critical ATC and navigation communications remain clear and uninterrupted during emergencies. The other options would either mute the captain, silence the intercom, or switch focus to the FO, which defeats the intended emergency prioritization.
