View Full Version : Dimming the cabin lights
I've been asked more than once why cabin lights are dimmed for takeoff and landing at night. It was then that I realised I didn't know the answer.... .All I could think of was that the pax's eyes would be slightly better accustomed to the dark if the worst were to happen. If that is the reason, then why do we let them keep their reading light switch on??. .. .Any suggestions for the real reason??. .. . <img border="0" title="" alt="[Confused]" src="confused.gif" /> <img border="0" title="" alt="[Confused]" src="confused.gif" /> <img border="0" title="" alt="[Confused]" src="confused.gif" />

Similar post a while back. The main ideas were as you mentioned. It takes the eyes over 30 mins to become adapted to the low lighting intensity found on such things as exit signs and those little lights found along the side of the aisle on the floor. If due to a cabin fire those little lights would be your only lifeline.. .. .Other popular answers involved. .a) Better view outside of approaching destination.. .b) Acft needs to conserve power to get enough power to take off (I guess some people like this one)

Is it mandatory to dim the cabin lights on night take offs and landings?? Or just up to individual operators?
Enhances the beauty of the Flight attendants.

TR4A - Brave comment that one! Good luck as the Chapesses (and possibly even some of the Chaps) will be after you for that. <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" />
Some of our Flight Attendants actually say this.

I was told that its to conserve power for the engines during t/o and landing. Sounds logical!

In our Crew Safety Manual it tells us that it is to "comply with safety regulations" but no reason given as to why. Could be to make it easier to see the emergency lights.

To save power?? Never heard of that one, and IMHO doesn't seem logical at all!. .. .In evening- and nightflights cabin lights are dimmed because of the 30 mins adaptationeffect. People would be linke blind moles in an emergency if not.. .. .P77
