When traveling, you may have noticed that aircraft cabins have their lights dimmed for takeoff and landing.
Yet, this process only occurs at certain times of the day.
In today's video, let's take a look at the reasoning behind this initiative.
Overall, light dimming happens when it is dusk, dawn, or merely dark outside.
The safety measure makes sure that passengers' eyes are adjusted to the darkness well-enough to notice the cabin's floor lights.
This process can help travelers be led to safety along the aisle if there is an emergency or evacuation.
Indeed, it would take a while for people's eyes to adjust if the cabin lights were on beforehand.
In fact, humans and their eyes can take between 10 and 30 minutes to fully adjust to a gloomy room.
Thus, any initiative to help speed up the process can make a significant difference.
