How does the Flight Crew notify the Cabin Crew during the flight?

• A. The Flight Crew will announce over the PA 'Nº1 to the flight deck'.
• B. The Flight Crew will inform the Cabin Crew via interphone.
• C. The Flight Crew will press the Cabin Attendant button and then announce over the PA 'Nº1 to the flight deck'.
• D. Ground control issues the alert to the Cabin Crew.

Answer: (C)

Notification to cabin crew is done using the cabin call system: the flight crew first triggers the Cabin Attendant button to alert the cabin, then uses the public address system to issue a specific instruction, such as “Nº1 to the flight deck.” This two-step approach ensures the alert is received by all cabin crew and that clear, direct action is communicated. Relying only on the interphone or on ground control wouldn’t reliably reach the entire cabin or provide the proper in-flight instruction.
