A question you’ve always wondered but never asked
Lowering cabin lights and raising window shades are standard safety measures during takeoff and landingâthe most criticalÂ moments of every flight. But what purpose do they serve? As it turns out, the dim lighting is a precautionary measure thatÂ allows passengersâ eyes to adjust more quickly during an emergency evacuation. As Chris Cooke, a pilot with a major domestic carrier, puts it: âImagine being in an unfamiliar bright room filled with obstacles when someone turns off the lights and asks you to exit quickly.â The raised window shades bring natural light into the cabin, just in case itâs needed.
