What should a flight attendant assess before verifying a passenger’s eligibility to sit in the exit row?

The correct focus for a flight attendant to assess before verifying a passenger’s eligibility to sit in the exit row is to look for any obvious conditions that would prevent a passenger from providing assistance in the event of an emergency. This includes considering factors such as physical disabilities, medical conditions, or any other limitations that could hinder a passenger's ability to assist in the evacuation process. The role of a passenger seated in an exit row is critical as they are expected to help evacuate the aircraft if necessary. Thus, ensuring that passengers sitting in these rows are capable of fulfilling this responsibility is paramount for safety.

Other potential assessments, such as flight history, passenger weight, or previous flight behavior, do not directly relate to a passenger's ability to assist in an emergency situation. While these factors may be important in other contexts, they do not provide relevant information regarding the immediate physical capability of a passenger to respond in an emergency. Therefore, the focus must be on identifying any conditions that could impede a passenger's ability to perform crucial safety functions.
