What is one critical action for flight attendants during expected turbulence?

The critical action for flight attendants during expected turbulence is to reinforce the need for seatbelts. This is vital because during turbulence, there is a significant risk of passengers being thrown about, which can lead to injuries. Ensuring that everyone is wearing their seatbelt helps keep them safe and mitigates the consequences of any unexpected movements of the aircraft.

Flight attendants play a crucial role in maintaining passenger safety, and their reminders about seatbelt usage are essential in promoting compliance and helping to prevent injury during turbulent conditions. This action also emphasizes the importance of adhering to safety protocols, which are designed to protect all individuals on board during flight disturbances.
