What is the correct command to shout during a brace position?

The command "Heads Down, Stay Down" is the correct phrase to shout during a brace position in an emergency situation. This command serves to instruct passengers to protect their heads and remain in a low position, which is crucial for maximizing safety during an impact. The instruction to keep heads down helps passengers brace for landing and minimizes the risk of head injuries from potential debris or jolts that could occur during an emergency.

The focus on remaining down reinforces the critical need to maintain a protective posture until it is safe to move. The terminology is clear and direct, ensuring that passengers understand the immediate action they need to take in a high-stress situation.
