What is the main purpose of a safety briefing before flight?

The primary purpose of a safety briefing before a flight is to ensure that passengers are aware of emergency procedures and the safety features of the aircraft. This briefing is crucial as it prepares passengers for potential emergencies by informing them about the location of exits, the proper use of seatbelts, and how to use safety equipment, such as oxygen masks and life vests. Additionally, it outlines procedures to follow in case of an evacuation or other emergency situations. This awareness can significantly enhance passenger safety and can make a critical difference during an actual emergency.

While other options may provide useful information, they do not fulfill the same safety-critical role as the safety briefing. In-flight entertainment options, destination weather conditions, and introductions of flight crew members, although relevant to the travel experience, do not focus on the immediate safety and preparedness of passengers.
