True or False: There is an aural chime heard in the cabin when the seatbelt sign is turned on and off.

• A. True
• B. False
• C. Depends on the aircraft
• D. Only for emergency landings

Answer: (A)

The statement is true because in commercial aviation, when the seatbelt sign is activated or deactivated, an aural chime is typically produced in the cabin. This serves as an important alert to passengers and crew members. The chime provides clear communication that indicates the need for seatbelt use or that it is safe to move about the cabin.

This feature is part of safety protocols designed to ensure that all onboard are aware of critical updates regarding cabin safety. It enhances situational awareness and reinforces compliance with safety regulations during flights.

While there may be variations in aircraft systems and features, standard commercial aircraft designs generally include this aural alert for seatbelt sign changes, making it an expected safety measure across the industry.
