What are life lines used for during an evacuation?

Life lines are essential tools used during water evacuations, primarily for maintaining the safety and organization of passengers exiting the aircraft. In the event of a water landing, life lines assist in guiding evacuees to safety, ensuring they remain oriented and are able to reach safety rafts or other flotation devices. Their design facilitates the rapid and orderly evacuation of passengers from the aircraft, especially in an emergency situation where panic could lead to chaos.

While each of the other options presents possible scenarios for airline operations, they do not pertain to the specific function of life lines during an evacuation. In turbulence, stability is typically provided through secure seating and safety protocols, rather than life lines. Baggage is managed through other means, such as baggage handling systems, and cabin crew support during service relies on different tools and procedures designed for in-flight service rather than evacuation scenarios.
