What is the first action to take when experiencing sudden turbulence?

When experiencing sudden turbulence, the appropriate first action is to discontinue service and secure carts. This is crucial because turbulence can cause unexpected jolts that might lead to injuries or accidents if service items are left unsecured. Ensuring that the carts are secured prevents them from becoming hazardous projectiles and protects both the crew and passengers from potential injuries.

Securing carts and discontinuing service creates a safer environment on the aircraft, allowing the crew to focus on managing the situation. This proactive measure also allows the crew to quickly assist passengers and react to any further observations of turbulence, ensuring safety throughout the remaining flight.

While remaining seated is important for safety during turbulence, it does not address the immediate need to protect service carts or items that could harm passengers. Notifying the captain of turbulence is typically done after ensuring that the cabin and service area are secure. Advising passengers to stand up during turbulence contradicts safety protocols, as it can lead to increased risk of injury.
