Why the pilot should reduce the cabin light when taking-off or landing a passenger airplane?

Question

Why the pilot should reduce the cabin light when taking-off or landing a passenger airplane?

Answer 1

I am a flight attendant so us in the industry know best. The flight attendants control the cabin lighting first off. We turn off the cabin lights for a few reasons. One being its a federal law. Two being so that there is no glare on the windows during the critical phases of flight so we can see all things outside the aircraft at all times. Three being in the unlikely event of an emergency, your eyes will not have to adjust rapidly so you can safely evacuate. Four being it conserves power. Any questions?

Answer 2

So the passenger are alert. this is also the reason youre not really ment to film an aircraft landing or taking of while youre a passenger because you will not be alert in an emergency situation.

Answer 3

psychological effect/affect on the passengers mind. Be seated, the plane is ready for take-off./land soon.

Basically, if there is a crash, the passengers will be able to see better as their eyes won't have to adjust to a low-light condition.

Answer 5

the answers with thumbs up are right.(i thumbed up the right answers) I would just like to say how absurd people are to answer questions to which they are nor qualified OR even know the slightest knowledge about.

Anyone want to know the actual truth?  Forget everything about rescue work, electrical power, and all that stuff.  

The REAL reason is that people boarding the aircraft on the next leg prefer them to be up so they can watch everything going on outside.  The head honchos at corporate have decided this is the best way to do things.  Raising the shades on descent means the FA's don't have to do it when the aircraft is in the gate.  One less job to do means the plane gets turned around faster and gets back to doing its job (making money) that much faster.

Not too exciting is it?

Answer 7

Crashes and mechanical problems are much more common during take-off and landing.  So, to allow the flight crew to be able to better see outside the aircraft, the lights are dimmed.  For this reason, they also ask that all windows be opened during this time as well.

Engines are powered by jet fuel so electrical systems for the lights do not impact in any way the performance of the engines.

Cabin lights are on a different circuit than flight deck lights so this would have no effect on the lights in the flight deck.  The dimming of the cabin lights is for the flight attendants only.  Lights in the flight deck are always dimmed during flight.

Answer 8

To see the runway lights better.

Answer 9

To allow vision outside and to prevent passengers eyes from having to adjust in case of an emergency. (crash)

Answer 11

More power for the engines.

Answer 12

DRINK

Answer 13

Takeoff is by far the most critical factor in a flight.  There are a few reasons why lights are shut off, one of them being if a generator / engine failure occurs while taking off.  Turning off unnecessary equipment is just a precaution.

Answer 14

To have a clear look out side.

Answer 15

to conserve the aircraft's power in case of emergency. lightings consume a lot of power you know. somebody told me also that it is in the law that aircrafts are required to switch off interior lights when taking off and landing. who knows

Answer 16

Hi:  The flight decks lighting system is separate from the passenger cabin.   Flight attendants control the brightness of the main cabin's interior.   We are taught to match the lighting with the outside ambient light for takeoff/landing.  This will allow passenger's vision to be adjusted to the exterior should an incident occur, with possible evacuation.

It has absolutely no impact on 'power for the engines'.

Answer 17

drink.

Good answer, Jason!

Answer 18

The light emitted causes and inside reflective glare on the windows. That may hinder a pilots vision .

Judging distance is crucial when landing . because you must set the plane in to a controlled stall. as the plane falls, the ground is there to catch it

Answer 19

Since lights take up a lot of energy in the cabin the pilot

lowers them to save energy.  This in case of emergancy and for good green ideas.  Some people are the type that sleep all the time so the pilot wants to be curdios and lower the lights for them.
