When should cabin crew conduct a passenger safety briefing?

The correct answer indicates that cabin crew should conduct a passenger safety briefing before every flight. This practice is crucial as it ensures that all passengers are made aware of safety procedures and emergency protocols regardless of the flight's duration. By conducting the safety briefing at the beginning of each flight, the crew helps to familiarize passengers with the aircraft's layout, the use of safety equipment, and the actions to take in case of an emergency.

Standard safety protocols require this briefing for ensuring that everyone on board has the information they need to maintain safety. Regulations mandate that flight crews provide this information as a standard practice, which helps create a safe environment for all passengers and contributes to an overall safer flying experience. The consistency of performing briefings regardless of flight length or specific situations enhances passenger preparedness and can significantly impact outcomes in emergency scenarios.
