Why is it that the cabin lights go off during the take off and landing phase of the flight? This may be a simple answer but so far the people ive asked havent got much of an idea and they're all lecturers on the damn subject!!
Appreciate if anyone can help...Thanks

from what i understand its so that peoples eyes can adjust to the dark if there is a failure and they have to evacuate quickly... so once their down the slides they can see were there going and not fall over and stuff. so no it isnt for passenger comfort like they say

Instresting question, I dont know why.

One question I had is why do some airlines (I've seen it done in a US Airways Express flight) request that the passengers leave the window shades up.



If it was said by us, then it must be true.

I think it's so ground crews would be able to see inside if they had to assist.

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.

Its simple if you have the light on inside you cannot see outside as well. Check it out for your self turn the lights on and look outside, then turn the inside light off.

It does take a long time for the eye to completely adjust, and turning the reading light on will ruin night vision anyway. But it is an extra precaution.

Are there reasons to have them on as well? I know Qantas is one airline that have all the cabin lights turned on at full during takeoffs and landings.

Interesting.
The Dimming of the Cabin lights during T/O & Landings is to get the Pax Vision accustomed to darkness in case of an Emergency to be able to view the outside better & the Emergency floor evacuation strips.

In case of an Evac, depending on the airline, the cabin crew will decide which doors not to use for evacuation. This is why it's very important to have the shades up, so they can see outside quickly.

You really don't want to evacuate to the right when the right wing is on fire. The thing is when you do open the door on the right, people will just flood out in a frenzy like lemmings, whether there's a fire or not. So that's why. The pilots usually cannot see that from the cockpit and they are working on their procedures as well, so most of the time, the cabin crew will decide this.

I asked my ex this question, hes a flight attendant for VS. This is so that passengers can react to any problems during take off, e.g. engine fire... If the shades are closed, passengers wont scream when an engine catches fire, flap fairing falls off and therefore flight attendants can't report to flight deck if they havent already realised.

A crash/abnormal situation will be known with out looking out.Closing Window shades wont help much.Better to leave it open & know whats going on.

And smoke won't flood the cabin (as quickly): British Airtours, Manchester

Yes, most (if not all?) airlines do.

Point noted.I guess the words gave a different impression as to wouldnt an emergency give a different vibration during a cruising flt.
