When a flight deck lockdown occurs, what is a flight attendant’s recommended action?

In the event of a flight deck lockdown, a flight attendant's recommended action is to ensure all procedures are followed accordingly. This is vital for maintaining the security and safety of everyone on board. Adhering to established protocols during such critical situations helps manage the potential risks and protect the flight crew and passengers from harm.

Following the procedures may involve securing the cabin, informing passengers of the situation in a calm and controlled manner, and preparing for any further instructions from the flight crew. By sticking to the established security protocols, flight attendants play a crucial role in supporting the flight crew and ensuring that everyone remains safe and the situation is handled according to organizational policies.

The other options would compromise safety and security. Leaving a post or allowing passengers near the flight deck could lead to confusion and increased risk during a lockdown situation. Taking no action would also be inappropriate as it would fail to address the critical security concern at hand.
