During take off and landing in the hours of darkness, why is it compulsory to have the cabin lights off ?

Question

But it's ok to have your reading lights on ?

Answer 1

It's so you cant tell by looking at them, who has s.h.i.t. themselves...........

Answer 2

Well, this rule is more understandable if you read the complete law. According to cvial aviation athority, passanger airliners need to have their internal cabin lights off and window shutters open during take off. The reason this done ist that if for some reason an engine catches fire, of a bird strikes the wing and if the pilot do not pick it up in their instruments in the cockpit, then the cabin crew can alert them. No lighting and open window shutters helps the rear cabin passanger see better the outside of the aircraft hence are more likely to spot a problem. ALL other aswers above are incorrect.

Answer 3

You correctly noticed that it is only during the hours of darkness, which gives it away. It is so that if there is an emergency, your eyes are already adjusted to the darkness outside.

In example, the planes roof of the cabin (The fusalage) suddenly breaks off. As your eyes have been in light, the sudden light loss means your eyes have to adjust and the precious seconds cost you the risk of your life.

It also conserves power so that more can be diverted to the reverse thrusters to slow the plane down.

Answer 4

I'm fairly confident the main lights are required to be off during takeoff/landing for safety; the idea is that the pax eyes should be adjusted to the ambient outside light in case of evacuation.

Of course they don't force everyone to kill their reading light, but the concept is still sound.

I have also seen FAs require that exit-row window shades be open (not always up, some exit row shades are upside-down) during takeoff/landing so that the smoke/fire will be visible during an evacuation. Makes sense to me.

Answer 5

Uh, no. What that announces is that there would desire to be a gadget to boot the main considerable cabin lights which will gentle up for the time of an emergency. contained related to Boeing and Airbus airplane, those platforms are battery powered, or sometimes, they use risk-free-t-glo strips that would desire to be maintained by potential of checking them for luminescence. So, collectively as you purchased the superb data from the FAA website, this would not say that the main considerable cabin illumination would desire to be became off for the time of take-off and landing, it in simple terms describes the gadget that would desire to be in place and operable in an emergency on any airplane used as a transport airplane. Drumgod - What are you speaking approximately? the electrical powered gadget is pushed by potential of turbines on the engines and, whilst switched on, the APU. whilst on the floor, it rather is the two the APU (whilst the engines are off), or floor capacity. Hydraulic pumps grant HYDRAULIC capacity.

Answer 6

It makes it easier for air traffic control to get a visual check on the plane. (You try looking at a plane with the cabin lights on in the dark!)

Answer 7

Why must you have the lights dimmed during the day as well? Seems silly when you can have your reading light on during the day and at night. If everybody (approx 165 people) had their light on, then how powerful would that be?

Answer 8

If the aircraft should have to abort the take off or god forbid, an emergency, the passengers eyes would be used to the dark and could find there way off the plane quicker....Safety.

Answer 9

So you can see out for traffics and not to get the cabin light reflected and observe for any objects out side would be hard to spot.

Answer 10

Its so your eyes are adjusted to the levels of darkness that would be experienced if the plane suddenly loses power and crashes........it also helps to see the emergency exit lights in the aisles.

Answer 11

so the pilot knows where the landing strip is.(he can only identify the landing strip by lights so when multiple lights are on it could cause the pilot to go off the runway)
