Which of the following is not a part of the BRIEF acronym?

The BRIEF acronym is designed to ensure effective communication and thorough preparation during critical phases of passenger handling and safety briefings. Each component of the acronym stands for a specific part of the process aimed at optimizing safety and efficiency.

The inclusion of "Bag strategy," "Review special information," and "ID display and verify minimum crew" aligns with common practices in facilitating safe travel and ensuring that all necessary information is conveyed to both crew and passengers. These elements revolve around considerations for passenger belongings, any unique passenger needs or situations, and confirming crew readiness.

"Prepare for passenger safety," while an important concept, does not specifically correspond to a component of the BRIEF acronym. The focus of BRIEF is more on procedural and communicative aspects rather than the preparatory tone suggested by this phrase. Hence, it is not included in the defined elements of the BRIEF acronym, making it the correct choice for what does not belong.
