Question

In aircraft why are the cabin lights turned off for take off and landing?

Answer 1

for the same reason you dont drive round in cars at night with the inside light on...it reflects of the screen so u cant see as much outside..

Answer 2

desert camel said it.  It serves the same purpose as not having lights on inside a car while your driving.

Answer 3

to make it more scariererer

Answer 4

that isn't always so, last month on the flight back from spain it was the first time i'd ever been on a plane when they turned the lights off for take off & landing. But it might be so the pilot gives more effect if he mucks it up.

Answer 5

the lights can s***w up the take off

Answer 6

To give the engines more power.

Answer 7

The lights should be on when landing due to, If there was a crash the Emergency Services can see inside the plane.

Answer 8

the lights are dimmed in the cabin for 2 main reasons: to allow passangers eyes and senses to adjust to the dark and emergency guide lighting (run mainly of batery packs) in case or emergency landing and/or emergency evacuation.

and also lighting and galley power ect. are powered by generators which are run from the aircrafts engines this uses up some of the engines full power. this is undesirable during take off and landing as this extra power will be required in case of an emergency or reroute ect.

this information may vary depending on aircraft but will apply to most commercial aircrafts in operation today.

hope this helps

Cabin lights, along with some other nonessential systems (like galley power, a major consumer), may be turned off to reduce generator loading. Generators rob the engines of a little bit of power and this is not desireable during take-off. When we trim the engines for take-off power during a test run, these nonessential systems are turned off as well. As for landing, once again that extra power from the engines will be needed in case an emergency go around is required. Most emergency lighting for the cockpit or cabin comes from battery packs, armed during take-off and landing. True, aircraft are varied in both procedure and construction. My above statements have the Boeing 767-200 in mind and my company's procedures.

Answer 10

So that you can see the emergency light in the dark if you get into difficulties.

Answer 11

So that your eyes are used to the dark ... just in case there's a need to evacuate the aircraft ;-)

Answer 12

because if there is an emergency during take off 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
