What action should a flight attendant take during smooth turbulence?

During smooth turbulence, it is important for flight attendants to remain attentive and responsive to the needs of passengers while performing their duties. The correct action is to maintain normal operations, which allows flight attendants to assist passengers and carry out their responsibilities effectively. This could include serving food and beverages, checking on the well-being of passengers, and ensuring that safety protocols are followed.

In this scenario, suspension of all duties or remaining seated is not necessary, as it is important for crew members to be available for assistance. Additionally, notifying passengers of severe turbulence would not be appropriate during smooth turbulence, as this could create unnecessary alarm and confusion among passengers. Therefore, continuing with all flight attendant duties aligns with providing a safe, comfortable, and attentive service experience for travelers.
