What must cabin crew do during moderate turbulence?

During moderate turbulence, cabin crew must prioritize the safety of all passengers and crew members on board. This includes stopping all service in order to ensure that everyone is securely seated with their seatbelts fastened. Moderate turbulence can pose a risk of injury to both passengers and crew if they are moving about the cabin or handling hot or heavy items. By ceasing all service, flight attendants can focus on monitoring the situation and ensuring that appropriate safety measures are being followed.

The other options do not adequately address the safety protocols required during moderate turbulence. Continuing all services as normal fails to account for the risks associated with turbulence, while only serving beverages does not provide the necessary caution needed during this time. Preparing for a potential emergency, while prudent, is a broader action that may not pertain directly to the immediate requirement of halting service during turbulence. The primary focus during moderate turbulence must be on maintaining safety, which necessitates stopping all service activities.
