Who has the authority to turn on the fasten seat belt sign during any phase of flight?

• A. Passengers
• B. Flight crew
• C. Ground crew
• D. Management

Answer: (B)

The flight crew have the authority to turn on the fasten seat belt sign because it is a safety control managed from the flight deck and used to secure the cabin under conditions the pilots deem necessary. The captain (or the pilot in command) evaluates turbulence, takeoff, landing, and other flight conditions and decides when passengers should buckle up. Once the sign is illuminated, cabin crew monitor compliance and assist as needed, but they do not control the sign themselves. Passengers, ground crew, and management do not have access to operate this in-flight safety indicator, which is why the flight crew is the correct authority.
