How long does the emergency flash light last?

• A. 4 hours
• B. 6 hours
• C. 8 hours
• D. 10 hours

Answer: (C)

Emergency lighting is designed to keep a visible path and usable illumination after a power loss so crew can find exits and guide passengers to safety. The handheld emergency flashlight carried by crew is built to run on its battery for several hours, with eight hours as the standard endurance. This keeps the light available through most realistic emergency scenarios, including extended evacuations, without adding unnecessary battery weight or complexity. Shorter runtimes wouldn’t meet the expected reliability, while longer runtimes aren’t typically needed for this device.
