What is one of the flight attendant's roles during the safety demonstration?

During the safety demonstration, one of the primary responsibilities of the flight attendant is to provide information on seatbelt use. This is crucial because seatbelts are a fundamental safety feature that helps protect passengers during takeoff, landing, and any unexpected turbulence. Discussing how to properly fasten and unfasten the seatbelt ensures that all passengers understand its importance and are prepared for any incidents that may occur during the flight.

Providing clear and concise instructions during the safety demonstration also helps create a safety-conscious environment and reduces the risk of injuries. While understanding technical aircraft details, organizing passenger seating, and discussing flight duration may be important elements of flight operations, they do not directly relate to the immediate safety procedures that must be adhered to during the flight, which makes the instruction on seatbelt use a critical focus during these demonstrations.
