When is it appropriate to discontinue the seat belt sign and begin service?

• A. Immediately after takeoff.
• B. When the captain determines it is safe to move about and turbulence is no longer expected.
• C. Only after all passengers are seated for service.
• D. After the cabin lights are adjusted.

Answer: (B)

The key idea is that the seat belt sign is a safety cue tied to turbulence risk, so it should be turned off only when conditions are stable. When the captain determines it is safe to move about the cabin and turbulence is no longer expected, passengers may walk around and service can begin. This protects everyone from unexpected jostling while still allowing normal cabin operations when it's appropriate. Immediately after takeoff is not the best moment to rely on, since conditions can still change and turbulence may occur soon after; turning the sign off then would be premature. Waiting until all passengers are seated for service is too restrictive—service can begin as soon as it’s safe to move about. Relying on cabin lighting changes has no bearing on turbulence or safety.
