What is required from the cabin crew during a lockdown besides not opening the flight deck door?

During a lockdown situation, maintaining focused and effective communication with the flight crew is crucial for the safety and coordination within the aircraft. Ceasing face-to-face communication helps to minimize distractions and ensure that each crew member can effectively monitor the situation, respond to instructions, and maintain situational awareness without additional interference or confusion. This allows the cabin crew to remain attentive to their surroundings and effectively manage passenger safety during a critical incident.

In this context, while other aspects like ensuring passengers are seated or using hand signals may be relevant, they do not carry the same level of direct importance in preserving the communication flow and clarity between the crew members and the flight deck. Maintaining radio silence with the flight crew, while necessary in some situations, can limit essential communication, which is vital for operational safety. Therefore, stopping face-to-face conversations stands out as particularly necessary in a lockdown scenario.
