What is a PBS in the context of passenger safety?

The term PBS, in the context of passenger safety, refers to a computer-controlled Passenger Briefing System. This system is designed to provide crucial information to passengers regarding safety procedures, emergency protocols, and other important announcements during a flight. The PBS helps ensure that all passengers receive consistent and accurate information, which is vital for maintaining safety on board. By utilizing a computer-controlled system, the flight attendants can efficiently manage and deliver these briefings, adapting them as needed based on various factors such as flight conditions or specific emergencies.

While other options may relate to various aspects of flight operations or cabin management, they do not specifically address the role of a Passenger Briefing System in enhancing passenger safety through standardized communication and briefing delivery.
