Things that look scary but have an explanation

Why do the cabin lights dim?

The lights just went dim. What is the crew expecting?

At night, the cabin lights are dimmed for takeoff and landing so your eyes adapt to the dark. If an evacuation were ever needed, you would not be blinded by stepping from a bright cabin into the dark, and you could see the exit lighting more clearly.

Window shades are raised for the same reason, and also so crew and passengers can see outside. Seats upright, tray tables stowed and bags stowed also help for the same reason.

Takeoff and landing are the busiest parts of the flight and where the rare accidents mostly happen, so aviation puts extra preparation into those minutes.

A little deeper

It takes the human eye several minutes to adapt fully to the dark. Dimming early gets you a head start.

Floor-path lighting leads to the exits and is designed to remain visible in smoke. Modern LED cabins also use colour shifts to ease sleep and wake cycles on long flights.

Honest limits: this is a precaution, not a prediction. Dimmed lights are standard on every night flight.
