Why do they turn off the lights in aircraft cabins on take off and landing at night?

so if there is an emergency during takeoff or landing and you have to evacuate you will be able to see where your going a lot better as your eyes will have adjusted to the dark

In case of an rejected take off (RTO) or emergency landing at night time. To get your eyes accostomed to the dark in case of an emergency evacuation. You need to see what you are doing if you have to jump off the trailing edge of a wing.

To get your eyes adjusted to the darkness so if there is an emergency evacuation, passengers and crew will be able to see once they have left the aircraft.

To see out better, no glare from internal lights

so that the captain can get as much power as posible to the front landin lights so it is easier to land and also to keep the glare to a minimum

They lights get turned off because in the event of an emergency evacuation:
1) Your eyes take time to adjust to the dark and
2) So you can see the emergency lighting along the floor in the aisle.

so it will be more easy for the captin to take control

So its not so easy to shoot them down.

Two reasons: To reduce overall power consumption and give the plane everything it needs to land (someone already mentioned this) and also to keep everyone calm and relaxed as possible as the plane touches down. With the lights off, passengers are more likely to put down what they are doing (they should be anyway) and sit back and relax themselves for landing.

So that you can see out the window. A lot of people who are not frequent flyers get a kick out of looking out the window while the plane takes off and lands. You get a better view when it's dark in the cabin.

the pilot is right, its to ajust your eyes to the outside darkness should there be a problem and u have to evacuate .milliseconds count in this moment

To minimise the glare for the pilot during descent through cloud, alot of light is relected around the aircraft.

Think of driving in fog with dipped lights and then turning the main beam on.

Get it?

Takes that load off the electrical system for landing.

to help your eyes adjust should there be a problem and you are in total darkness

Liam G

So your eyes can adjust to the darkness should you have to evacuate the plane in an emergency. It takes time for the eyes to adjust to changes in light tensity - which could be a hinderance in an emergency evacuation. You may note at night in the house before you go to bed and in a light room and if the lights are off in the bedroom - you can not see objects that easy (depending on how dark the room is) - but later as your eyes adjust you can make out objects etc.

Hope this helps.

probably becuase they need more electricity for the other components on the plane...
