Why do they dim the lights on an aircraft at night for take off and landing?
Answers:
FUN is correct, they dim the light so the passengers eyes get accustomed to the darkness in case there is an emergency on takeoffs and landing. The exit signs and placards illuminate but if there is too much light in the cabin nobody can see them.
Next time you board a commercial aircraft look at them. You really can't see them much and most people ignore them. But kill the cabin lighting and you will notice they all glow.
Btw the floor lights are called eel lights, those run on battery power.
They don't dim the aicraft lights for T/O or landing. All lights are on and on as bright as they can be.
They switch power from there to the engines and the pilots' controls ie the power to light the lights is reduced so they become dimmer
So the pilot and the air hostess can have a cuddle.
I believe the lights dim as the aircraft needs more power for the task at hand.i.e., taking off, landing, and such.Sounds good to me.
To reduce the amount of power consumption to the main area of the aircraft and make that "extra" power available to say the engines and wing flaps.
b coz they dnt want 2 waste electricity??
they dnt want people 2 c them take off??
they dnt want 2 use that much power bcause the aeroplane needs it 2 take off and land?
i juss made all these up
hope i helped alittle
its nothing to do with the power. its so the crew and passengers can be more aware of their surroundings. god forbid anything should happen on take off or landing, if its dark outside and the lights are on in the cabin, you won't be able to see outside. its important for crew and passengers to be alert and aware of changes outside at the crucial stages of take off and landing. its also a CAA requirement.
So you can take a quick nap.
Excellent questions and I always asked myself that.
I already asked an air-hostess but she didn't know the answer.
Don't listen to the previous answers as they're not true, especially that one who said that when the engine consumes more power the light becomes dimmer. The cabin crew dim the light themselves (according to the regulations of the take-off and landing) and it's never automatically.
I know that I didn't answer your question but at lease I want to tell you about the wrong answers for not to take them. I'm also looking for an answer.
This is a safety consideration. In the event it becomes necessary to evacuate the airplane, your eyes are already adjusted. Otherwise, it takes at least several seconds to go from bright light to being able to see in the dark.
To see the luminated strips marking the way to the exit on the floor.
Also it is so other aircraft dont mistake the lights in the plane for signals, whilst take off and landing.
because it is night time and some ppl will b sleeping!! so it doesnt wake them up!!
Cabin lights are dimmed for night t/o and landing to enable pax to have what is in effect 'night vision' in the event of an emergency. Additionally the floor guidance illuminated strips are far more effective as they are designed to 'glow' in the dim light showing the pax the way to evacuate should it be necessary.
They dim the lights so that passengers have trouble seeing.
That way there is less panic in the cabin as it hurtles out of control and hits the ground at 500mph.
Enjoy yer flight yawl!
they are very hot lamps. they make spark fuel vapors without a breeze of somekind if on full blast with plane at rest.
To set the mood.
some airlines have mood lighting in first and business class.
I've been told by a BA worker that this is done due to the fact that take off and landing is generally when an aircraft is most vulnerable and at night, they dim the lights as if anything should happen, people's eyes will be accustomed to the dark and they would be able to find their way out of the aircraft in an emergency if required to.
so that the passengers and crews eyes are accustomed to the dark - take off and landing are the most dangerous times of an aircrafts trip - so if an accident you will be able to focus on your surroundings, rather than having to wait for your eyes to adjust to the dark which might cause a delay in your reaction / escape.
