What does PA stand for in airline terminology?

• A. Public Address Passenger Announcements
• B. Public Announcement
• C. Passenger Alert
• D. Public Access

Answer: (A)

PA refers to the Public Address system—the setup used to broadcast messages to passengers on board and in the cabin. The best choice captures this idea by pointing to the Public Address system delivering Passenger Announcements, i.e., PA announcements heard by travelers. In practice, we use terms like "PA announcements" to describe the messages crews relay through that system. The other options miss the idea of a broadcasting system (Public Announcement) or refer to things not used in airline terminology (Passenger Alert, Public Access).
