When should passenger briefings generally be conducted?

The conduct of passenger briefings before takeoff is crucial as it ensures that all passengers are informed about important safety procedures and protocols before the flight begins. This timing allows passengers to understand the specifics of the flight, such as emergency exits, the use of seatbelts, and other vital instructions while they are still attentive and ready to absorb the information. Briefing passengers prior to takeoff helps increase their preparedness in case of an emergency and enhances overall safety throughout the flight.

Other times mentioned, like before landing or during cruise, may not provide the same level of awareness or opportunity for passengers to fully engage with the information. Briefings conducted after landing would also be impractical since the flight has concluded, making it irrelevant for passenger safety during the actual flight.
