What is the main responsibility of flight attendants during turbulence?

The main responsibility of flight attendants during turbulence is to ensure passengers are safely secured. This is crucial because turbulence can lead to sudden movements of the aircraft, which may cause passengers to be thrown around if they are not properly seated with their seatbelts fastened. Flight attendants must assess the situation quickly and ensure that all passengers are aware of the need to secure themselves. This may involve reminding passengers to fasten their seatbelts and securing any loose items that might become hazardous. The focus during turbulence is on passenger safety and well-being above all else, making this responsibility paramount.

The other options involve activities that are not appropriate during turbulence. Serving beverages quickly could compromise safety, as flight attendants should prioritize the stability of the cabin environment. Entertaining passengers with jokes is not suitable during turbulent conditions, as most passengers may be feeling anxious and need to focus on safety rather than distraction. Preparing emergency exits, while a critical procedure, is generally not the immediate concern during turbulence unless there is a significant threat to the flight. Thus, ensuring passengers are secured is the foremost duty during such events.
