When the red indicator flag is down, do oxygen masks in that compartment deploy in the event of decompression?

When the red indicator flag is down, the oxygen masks in that compartment do not deploy in the event of decompression. This flag typically indicates that the oxygen system is not in an active state or that there may be an issue with the deployment mechanism. In many aircraft, the deployment of the oxygen masks is contingent on specific conditions being met, such as an activated system or a specific signal indicating the necessity for oxygen.

In this case, the presence of the red indicator flag suggests that the system is not ready or that it has been disabled, which means the oxygen masks would not automatically deploy during an emergency requiring them. Knowledge of this operational function is essential for flight attendants, as it impacts their response to emergencies and assists in ensuring passenger safety.
