why do the lights swithed off in an aircraft while taking off or landing?

Answer 1

take off and landing is the critical phase for a flight. aircraft has what we call a integrated drive generator as the engine spins it drives the generator. lights in the cabin are switched off because if an engine fails the generator on the other engine can supply power to the critical systems suppored by the failed engine and stops the extra load which is put on by non essential items i.e cabin lights, coffee maker,oven etc.

Answer 2

An Aircraft consumes the maximum fuel and power during take off and landing. In order to save as much energy as possible from not so important resources, the lights are switched off at these times.

Answer 3

So the flight team and passengers are familiar with the lighting fixtures outdoors the plane in the variety of an emergency and function to evacuate the plane. similar reason that the window colour might want to be up for take off and landing, so the flight team can see out and verify the problem if an emergeny arose.

Answer 4

So that you don't learn from the pilot how to take the flight off and landing on your own later on.

Answer 5

Taking of and landing are critical stages, so you reduce the non-critical consumption to have extra power if needed.

Answer 6

So the passengers can't see the horror on each other's faces and start a panic.

Answer 7

I think because the runway is filed by lights and it's enough

Answer 8

Because it is easier to see the runway which has lights of its own

Answer 9

Its nothing personal, believe me. The pilots dont exchange kisses during this time...

Answer 10

To preserve power, I think as during takeoff, lot of power is required.
