It should depend on the policy of the relevant aviation authority however in practice I believe it is just a case of whether the individual airline thinks it is a good idea or not.

Excuse me for coming in late on this, Willow, but to amplify your query, why don’t all Airlines do this?
Which don’t? – not quite sure at the moment but I think either KLM or LH don’t.

Not a daft question at all willow and the boys have given you the text book answer.
By the way if more performance is required for departure the air conditioning packs can be turned off which allows the engines to produce more thrust.

Plus having the lights off gives a much clearer view of the surronding area on take-off 😉

The main reason is that if the aircraft needs to be evacuated the crews and passengers eyes are adapted to darker conditions.Also that the exit signs are more visible.If you went from a bright cabin out into darkness people would not be able to see very well causing more panic and confusion.If their eyes were adapted it would make the whole thing run much better.

Makes sense doesn’t it. Thanks very much for that.

This is FAA and other regulation administration rules.
If there is a problem during take-off and if there is an emergency abandoning , the passengers must have their eyes used to darkness in case of no light in the cabin.

I’ve often wondered about that myself ?
