DS2 is used to indicate which condition?

Explanation:
DS2 is used to indicate a flag drop condition. This indicator signals that the visual status flag, which communicates a specific safety or status condition, has dropped from its position. When a flag drops, the normal status cue is no longer valid, so you must stop, locate or replace the flag, and reestablish the safe condition before proceeding. It isn’t showing power status, airflow conditions, or triggering a local audible alarm—those would be separate indicators or alarms. The key point is that DS2 directly flags the loss of the status marker provided by the flag, ensuring you don’t rely on an outdated signal.
