Until when should you remain in the brace position after landing?

The correct understanding of the brace position after landing is that you should remain in this position until you are off the active runway. The purpose of maintaining the brace position is to protect yourself during landing from potential hazards, including unexpected movements and the need for a quick evacuation if necessary.

Remaining in the brace position until off the active runway signifies caution because even after touchdown, there may be a need for swift action. It ensures that passengers are prepared for any sudden events that could occur as the aircraft slows down and navigates away from the runway.

While other phases, such as taxiing or until the aircraft comes to a complete stop, might seem relevant, the critical factor here is the active runway context. Being on or off the active runway is significant in aviation safety protocols, which prioritize readiness for immediate evacuation or other actions that may be required in case of emergencies.
