When must flight attendants assume the brace position?

Flight attendants must assume the brace position prior to every takeoff and landing as a safety protocol. This is because these phases of flight are considered the most critical and potentially dangerous, especially during unexpected events such as turbulence, emergency landings, or other incidents. Assume the brace position ensures that flight attendants are prepared to protect themselves and assist passengers effectively in case of an emergency.

While it might seem logical to think about the other options, they do not align with the established protocols for safety. For example, assuming the brace position during taxi to the gate or only in the event of turbulence does not adequately prepare the crew during critical flight phases. The requirement to take this position also is not activated simply by the seatbelt sign being turned on, as it serves a broader purpose related to the entire takeoff and landing sequence, emphasizing the importance of readiness in those moments.
