Which device automatically plays the decompression PA?

• A. PRAM
• B. Intercom
• C. Cabin PA
• D. Public Address System

Answer: (A)

During a decompression, automatic, pre-recorded instructions need to reach every passenger quickly and consistently, even if crew aren’t at their microphones. The device that stores and automatically plays those emergency passenger announcements is PRAM. It triggers the decompression PA message without requiring crew action, ensuring immediate guidance like “don oxygen masks” and “return to your seats.” The intercom is for crew-to-crew or manual announcements, and the cabin PA/public address system refers to the overall system used by crew to speak to passengers—these do not automatically initiate the decompression message without PRAM’s automatic triggering.
