Bright days no lights, dark nights all lights?

[newflyer]

Forgive me for the title. Another question that I'm sure has been answered...

Anyone know why the dim the cabin lights for take-off in the daytime? Happened on my 0825 flight out of Brisneyland yesterday. Was clear, bright and sunny outside...

It's been a while since I've taken a night flight, but from memory, I think they turn the cabin lights on?

Cheers!

In an emergency, it makes it easier to see outside of the plane. (Don't think they are on bright at night, just dim)

I believe the reason is to accustom you to the daylight (or lack of light) in case of emergency evacuation.

..or was it to enhance the cabin crews appearance....hmm, I am confused now

Hang on......... are you saying QF crew isn't good looking?

 

[serfty]

CSMs have been dimming the lights for takeoff and landing as a matter of Qantas policy for over a year now.

As oz_mark posted it in case of emergency situations.

On two recent QF flights I have actually heard the CSM say:

"We will be dimming the cabin lights for take-off as this improves the appearance of the cabin crew" ...

Its a cost saving exercise, perhaps ... Light bulbs last longer, use less energy

Right, right, I see (no pun intended). Thanks for the super quick response - and, as always, much appreciated!

Just don't get NM going on his theories of light vs darkness :!:

Its a safety issue. I have flown much regionally arounf Africa and Asia - very common there as well

But which is the natural state? Is darkness the lack of light, or is light the lack of darkness? It all comes down to scientific (or engineering in my case) proof!

Darkness is a dimmer form of light therefore not a lack of light...

Anyway, I thought the cabin light thing was so spectators and aircraft spotters could see the look of horror on PAX faces at QF landings... (or in a couple of recent landings for Mr! - multiple landings - you know, the ones where the pilots keep trying to dislodge your kidneys by bouncing down the runway...)

I am not even entering into that discussion - my brain is bouncing just trying to work out what you guys have said already!

Mr!

They are simply testing the structural rigidity of the contents of the conveyance... Sheesh, what next, that all the sudden problems on QF are as a result of somehthing sinister behind the scenes and not because of maintenance issues...

I doesn't really matter as long as the sun keeps rising in the morning. When the sun stops rising then we all start to worry....

... and by then it's all too late :!: :shock:

If you travel fast enough westbound for long enough, your condition can be met .

[scotchonrocks]

All airlines are compelled by regulation to dim lights and open window shades for a number of reasons.

1) To accustom eyes to low light levels in the event of a de-planing
2) In the event of a high G landing, the electrics to the lighting will be tripped. Having the lights dimmed prepares for this.
3) Window shades open allow pax and FA's to see where the smoke/fire is in an emergency (know which way to run).
4) Above also allows emergency rescue crews to eyeball pax inside plane from outside.

What really gets up my nose however is the placing of life-jackets on aircraft. There has hardly been a single known life saved with them, on the contrary, several lives have been lost with them preventing escape from a flooded cabin. They SHOULD place smoke filters for escape breathing instead. The trouble is, the legislation is so entrenched, it will take a catastrophe to see it introduced

Let me get this right NM, if I travel fast enough westwards, I can actually arrive before I departed?
