What is the primary function of the pre-recorded PA system or PRAM?

The primary function of the pre-recorded PA system, commonly referred to as PRAM (Public Address Messaging), is to play safety demonstrations in multiple languages. This capability is essential for ensuring that all passengers, regardless of their native language, receive critical safety information before the aircraft departs. This information typically includes instructions on how to use seatbelts, the location of emergency exits, and the procedures to follow in case of an emergency.

By providing safety demonstrations in multiple languages, airlines can comply with aviation safety regulations and enhance passenger understanding, thereby ensuring a safer flying experience for everyone onboard. The use of a pre-recorded system is efficient and guarantees that the safety information is delivered uniformly, minimizing the risk of miscommunication or omissions.
