During a ditching drill, what is the command given to passengers at 30 seconds before landing?

The command given to passengers 30 seconds before landing during a ditching drill is "Brace, Brace." This command serves as a critical alert that instructs passengers to assume the brace position to minimize potential injuries during impact. The brace position typically involves the passenger leaning forward with their head down, placing their arms over their heads or clutching their knees to protect vital areas of their body.

This command is standardized across aviation safety protocols, emphasizing the urgency of preparation for an emergency landing on water. It is essential for ensuring that passengers are adequately prepared for the impending impact, promoting safety and reducing the likelihood of injury while increasing the chances of survival.

The other options do not provide immediate instructions for impact preparedness, making them less relevant in this specific context. Commanding passengers to secure personal belongings may detract from the focus on safety, while commands like "Life vests on" relate to post-impact survival rather than immediate impact preparedness.
