What is required of crew members when they are outside the cockpit during sterile flight deck periods?

During sterile flight deck periods, crew members are required to refrain from any contact with the cockpit. This regulation is in place to minimize distractions for the flight crew, allowing them to focus entirely on the operation of the aircraft. The sterile cockpit rule applies during critical phases of flight, such as takeoff and landing, and it aims to ensure that all communications and actions within the cockpit remain clear and unimpeded.

By minimizing distractions, the risk of misunderstanding or miscommunication is reduced, which directly enhances safety. This regulation is vital for maintaining the highest levels of situational awareness for those in control of the aircraft.

In this context, while monitoring cabin announcements or conducting safety demonstrations can be important for ensuring passenger safety and comfort, these actions do not align with the needs of the cockpit crew during these critical phases. Therefore, it's essential for cabin crew outside the cockpit to maintain that separation to support safe flight operations.
