There is probably a really obvious answer to this but....why when you are taking off or landing at night do the cabin crew dim the cabin lights? I would have thought that the more lights on in the plane, the better because it would be more visible to other planes. They always say it's 'due to air traffic regulations' or something. But why? Or am i just missing something really obvious??

Cabin lights are dimmed during (night) take-offs to allow you the best opportunity to see(eyes adjusted to darkness) in the event you have to evacuate a dark aircraft.

When you walk from a lighted area into a darker one, how long does it take your eyes to adjust? Keeping this in mind, put yourself on a well-lit aircraft when suddenly all H--- breaks loose and you must evacuate, quickly, into the darkness of the night.

The lights are dimmed so that if a evactuation is need on the gound at night when you exit the aircraft your not temporarily blinded. try walking out of a bright room into a dark room, it usually take your eyes to adjust to the new light level.

In case of an evacuation, passengers and cabin crew can adjust to the dark more easier if the cabin lights have been dimmed.

It also reduces the fire hazard as it reduces the spark/heat sources vulnurable to a crash or heavy landing. It would be ironic for a survivable accident to become fatal due to a cabin fire caused by either the wiring or lamp fixtures...... Thus the reason for switching of in the daylight.

The Flight attendants operate the switching not the pilots.

Not every flight dims interior lights for takeoff and landing. I don't think it has anything to do with safety as you are quite welcome to use your reading light if you like.

The simple reason is so pax can get a nice view of the city and surrounds as the plane takes off or lands. If interior lights are left on, reflections off the glass makes it hard to see out... Simple as that

You are wrong!! Plain and simple. It is for Safety precaautions and FA's just donot bother about telling passengers about the reading lights as they get in a teasy fit. On the newer Airbus planes i.e The A320 Reading lights donot come on till the aircraft is at an altitude of 10000 feet.

It is solely for Safety. E-mail your local Airline and they will tell you the same thing.

Airnewzealand (mikey)
im sorry to disapoint you but i was on a A320-200 and A321 last year, a A330-300 2 weeks ago and a A340-300 last week. (as you know all airbus's) the flights were all started during the day and prgressed on to night where we landed at night time

the reading lights were all operational.
but they dimmed the lights at night for approach/landing and taxying.
It was my observatyion because my dad read magazines on all the landings with the reading light ON.

kind regards and happy flying

Main lights are dimmed for the reasons of evacuation as stated above, as far as I know it's regulatory..... reading lights can be switched on though.....these lights are already pretty dim, and you can stare at them without affecting your eyes.......I take it there's no need to turn them off.......

This question has come up a hundred times by now, and almost everybody here on this forum finally answers that question correctly. Except for Tullamarine. And with such confidence. He must be new.

Hmmmm...

I have heard the FA on VS between BOS and LGW state unequivocally that the cabin lights are being dimmed during the nighttime takeoff as a safety precaution. Also, the VS flight lands before sunrise at LGW during the winter months, and they announce a second time that "because it is still dark at Gatwick, the cabin lights will be dimmed for landing"

While this procedure seems to be practiced on all flights, I was on a flight a few weeks ago where the lights were not dimmed during take-off. Hmm...

Flights doing this are putting passengers safety at risk. Just imagine if the plane crashed just after V1 and the passengers were not used to the darkness. What would happen??

Airbus_A340: I just found out that only some airlines have them installed. Sorry about that!

Also Cabin lights are also dimmed during the Day, but it is to hard to see that they are being dimmed. If you read my first post it will tell you why they dim them during the day.

PS: Airbus_A340..... How did you like the A330. I have heard AirNZ are going to be getting some. Please tell. Thanks.

I don't understand this whole arguement...I mean, the cabin lights aren't really that bright anyway...and even if something did happen and we lost electricity I'm pretty sure the light from the airport shining on the plane, as well as the emergency lights in the aisle, over the exits ETC would provide enough light to make do. I can't see that much of a difference when they dim the lights on the flights I've been on anyway.

Hi Airnewzealand
The A340 and A330 flights were exactly the same, except for the fact of 4 engines over 2.
The A330/40 is a great plane and you wont be disapointed!


post above=Lights are turned down ANYWAY even though they may not be bright, it would help if there was an emergency!!
kind regards

As a Flight Attendant and one that prefers to fly at night. When cabin lights are turned on especially to bright the cabin lights are blinding and personally it gives me a headache. on Airbus we have the FAP(flight attendant panel) on that panel includes the lighting control DIM 1, DIM 2, and BRT (for bright) it also controls diffrent sections of the cabin. As our flights go from early evening as sunsets to night we adjust the cabin lights accordingly there are time's like on short 45-50 min flights where the flight goes into night(dark outside) the cabin crew forgets to turn the lights off because they are being rushed to complete the cabin clean up from beverage service but all FA's must remember to turn the cabin lights off for takeoff and landing this is part of pre arrival and departure duties at night. As stated by many of you and I am sure those of you who would agree with me are crew members too. The cabin lights are turned off at night for take off and landing in case of an emergency evacuation your eyes would better acclimate to the dark of the outside of the aircraft. As you who would agree with me the runways/taxiways are pitchblack when you takeoff or land at any airport at night. as far as individual reading lights in the passenger service unit above each seat. it only gives off just enought light (not blinding light) for that one passenger in that seat that is why we call it individual reading lamps. The cabin is still dark even when the reading lamps are on.   Fly safe!

Hello guys,

I see lots of Qantas planes in Singapore every evening. I noticed that they don't dimm their lights on take off and landings. 90% of Qantas flights don't, even when it gets dark.

Why?
