Who is required to make the announcement for passengers to keep their seatbelt fastened even when the seatbelt sign is off?

The requirement for a crew member to make the announcement regarding passengers keeping their seatbelts fastened, even when the seatbelt sign is off, is grounded in safety protocols and passenger compliance. This announcement is critical as it reinforces safety measures that might not be immediately obvious to passengers who might assume that they can move around freely once the sign is turned off. A crew member is trained to communicate important safety information and ensures that all passengers are informed about the necessity of remaining buckled in, particularly during times of turbulence or unexpected in-flight conditions.

Additionally, regulations and best practices within the aviation industry dictate that, while pilots are responsible for overall flight safety, the specific communication of various safety instructions is typically designated to flight attendants or other designated crew members. This approach promotes a clear understanding of safety protocols among passengers and aligns with the crew's responsibilities. Thus, a crew member is empowered to address these important safety issues, ensuring that passengers maintain their seatbelt usage throughout the flight as needed.
