Who initiates the PA instruction to begin disarming the doors?

• A. The Captain
• B. FA1
• C. The Agent
• D. Any FA

Answer: (B)

Starting the PA instruction to begin disarming the doors is a cabin coordination task handled by the lead flight attendant in charge of announcements and crew actions. FA1 is that designated person, trained to issue cabin-wide communications and coordinate the rest of the crew to execute procedures in the correct sequence. The captain oversees the flight deck and may authorize actions, but typically does not initiate cabin PA announcements for this kind of procedure. An ordinary flight attendant would lack the designated authority to start a critical, coordinated action that affects multiple crew members. So the person who initiates this instruction is the lead flight attendant, FA1.
