When the seat belt sign is turned on, who is responsible for making an announcement?

When the seat belt sign is turned on, both the Flight Attendants and the flight deck crew are responsible for making announcements. This collaborative responsibility ensures that all passengers receive vital safety information in a timely manner. The flight deck crew may initiate the announcement to notify passengers of turbulence or other safety concerns, while Flight Attendants may reinforce this message, ensuring that passengers are aware of the need to fasten their seat belts. This dual approach maximizes communication effectiveness and provides clear instructions, enhancing overall safety and compliance throughout the cabin.
