What sequence signals an emergency call to all flight attendant stations?

• A. INTPH+CABIN
• B. INTPH+ALL+1
• C. INTPH+ALL
• D. INTPH+ALERT

Answer: (C)

In an in-flight emergency you want every flight attendant to receive the call at the same moment, so the interphone paging must be directed to all stations. The interphone signal is started with the interphone identifier and then targeted to all by selecting ALL. That combination—INTPH+ALL—broadcasts the emergency call to every FA station simultaneously, ensuring coordinated response and announcements. Other sequences would reach only a subset (for example, just the cabin crew) or use a form that doesn’t page all stations, so they wouldn’t achieve the same broad, immediate alert needed in an emergency.
