When is a passenger briefing typically conducted?

A passenger briefing is typically conducted prior to takeoff or upon encountering a significant flight disruption because this is when it is crucial for passengers to receive important safety information. Before takeoff, passengers need to be informed about safety procedures, emergency exits, the use of seat belts, and any specific instructions pertinent to the flight. This ensures that everyone is prepared and aware of how to respond in the event of an emergency.

Similarly, during significant flight disruptions, such as turbulence or potential emergencies, a briefing provides timely and relevant information to keep passengers informed and calm. This proactive approach helps to minimize confusion and promotes safety by ensuring that passengers understand the necessary procedures to follow during both standard and irregular operations.

The timing of passenger briefings in other scenarios, such as during landing or after meal service, does not allow for the same effectiveness in conveying vital safety information. In emergencies, briefings may indeed occur, but they are not the sole context for such important communications.
