During aircraft movement, what must flight attendants do?

During aircraft movement, it is essential for flight attendants to remain seated with their seat belts and shoulder harnesses fastened. This practice is primarily a safety measure. When the aircraft is taxiing, taking off, or landing, any sudden changes in dynamics could occur, which may pose a significant risk of injury to flight attendants who are not securely seated. By keeping their seat belts and shoulder harnesses fastened, flight attendants ensure their safety and maintain their ability to respond quickly in case of an emergency.

The role of flight attendants is critical during these phases of flight, but their primary responsibility is to prioritize safety; thus, remaining seated with seat belts secured is necessary to protect themselves, allowing them to be in a position to assist passengers effectively as soon as it is safe to do so.
