What is the purpose of announcing the "sterile cockpit" protocol?

The purpose of announcing the "sterile cockpit" protocol is to minimize distractions during critical flight operations. This protocol is vital during specific phases of flight, such as takeoff and landing, when safety is paramount. The sterile cockpit rule restricts non-essential activities and conversations in the cockpit and cabin, ensuring that crew members are fully focused on their tasks. This heightened awareness helps prevent errors and enhances overall safety for both passengers and crew. It is crucial for flight attendants to recognize and adhere to this protocol, as maintaining a distraction-free environment contributes significantly to operational safety at these critical points in the flight.
