What is the primary purpose of the arm door announcement?

The arm door announcement is primarily designed to ensure passenger safety during critical phases of flight, particularly during takeoff and landing. This announcement serves as a crucial safety measure, informing both the crew and passengers about the status of the aircraft's doors and reinforcing the importance of proper procedures. It is essential for flight attendants to monitor the doors to guarantee that they are properly secured, as any failure in this process could compromise the safety of everyone on board.

While the other options address important aspects of inflight procedures, such as initiating service or alerting crew members about cabin conditions, the core focus of the arm door announcement centers exclusively on safety protocols. This emphasis on safety underscores the airline's commitment to protecting its passengers and crew throughout their travel experience.
