The question is very important and thank U for asking such a question.
All the answerers has given fantastic useful information.
Thanx for them.
2) So that the cabin crew have full view of what is happening outside during take off and landing
3) Ipods and electronic gadets interfere with the air traffic frequencies and navigation during take off and landing due to electromagnetic radiation.
4) If the seat /tray is kept down then it restricts the movements of the cabin crew and passengers in case of an emergency during take off and landing.
The rules are confusing, but the safety concern is real...
1. Cabin lights are dimmed for night t/o and landing to enable pax to have what is in effect 'night vision' in the event of an emergency. Additionally the floor guidance illuminated strips are far more effective as they are designed to 'glow' in the dim light showing the pax the way to evacuate should it be necessary. Easy to see the luminated strips marking the way to the exit on the floor..
So that the passengers and crews eyes are accustomed to the dark - take off and landing are the most dangerous times of an aircrafts trip - so if an accident you will be able to focus on your surroundings, rather than having to wait for your eyes to adjust to the dark which might cause a delay in your reaction / escape.
its important for crew and passengers to be alert and aware of changes outside at the crucial stages of take off and landing.
2. You are asked to raise your shade so that in the event of an ...more
Upon descent (and also if you are taking off at night) they dim the lights to help your eyes adjust to the darkness, so if anything happens and it goes dark, you're not suddenly blinded while dashing for the exits. It makes the emergency path/exit lights more visible, as these might be the only lights you see in an emergency. As with the shades, it allows you to see outside for orientation, because with the cabin lights burning brightly, the glare would make it impossible.
