Have you ever wondered why the light in the aircraft are dimmed or turned off when the aircraft is landing or taking off? Here we have the answer to your question.
In aircraft, it is a common practice for airlines to dim or turn off cabin lights at the time of landing and take off. However, you must have noticed that this practice is not operated every time during landing or takeoff; it is only done at certain periods of the day. But why is that?
Why is the change in light required in the aircraft cabin?
To understand the practice, we first must know when it is operated. Airlines generally use this practice in the twilight hours, i.e., dusk and dawn.
The safety feature ensures that passengers’ eyes are sufficiently acclimated to the darkness to detect the cabin’s floor lights. In the event of an emergency or evacuation, this procedure can guide passengers to safety along the aisle. If the cabin lights were turned on beforehand, it would take a while for the passenger’s eyes to adjust.

10 to 30 minutes to properly adjust to a dimly lit environment
Humans can take anywhere from 10 to 30 minutes to properly adjust to a dimly lit environment. As an outcome, every initiative that aids in the speeding up of the process can have a big effect.
While onboard, crew members frequently ask that the window shades be lifted in addition to the lights being dimmed. In the event of an emergency, this element also contributes to increased visibility. The better one’s orientation, the better one’s judgment.
Aircraft manufacturers realize the importance of lighting, and hence they have included the features to control lighting in the aircraft. The lighting features were extensively promoted during the pandemic to help the passengers follow social distancing.
Using these developing features and technologies, the aircraft’s crew members can easily and more comfortably guide the passengers to follow their rule.
