American Airlines Flight Attendant Training: 777 Practice Test

The task tests understanding of who is responsible for specific preflight checks on the 777-300. The Public Address preflight of the OFCR is assigned to the flight attendant designated to handle in‑cabin communications and PA system checks. This ensures the PA, microphone, speakers, and the OFCR unit are tested by the same person every flight, providing consistent accountability and reducing confusion during preflight.

FA 10 is the correct choice because, according to the standard 777-300 preflight duties, that crew member is assigned to perform the PA preflight of the OFCR. The other attendants have different preflight duties assigned to them, so they wouldn’t be the one responsible for this specific check.
