Why Are Cabin Lights Dimmed During Landing?

Question

Why do they turn the lights off when the plane's landing?

Answer 1

There are two main reasons why cabin lights are turned down before landing. First of all, it allows conserving energy in this critical stage whereby more power can be directed to the brakes and the generator. Secondly, it serves as a safety precaution. In case of an emergency when it is dark outside, dimmed cabin lights facilitate passengers’ ability to adjust to darkness more quickly, enabling them to see the floor lights which guide toward the exits.

The pilots DO NOT dim the lights for "energy". I don't know where you got that from, but it's just not true. The lights use such a small amount of energy, and the other functions of the plane are using the same amount of energy for the entire flight. There is no need for extra energy during landing.

Also, the plane does not say "decide", it says "minimums". I don't think there is a single plane that says "decide".

Ground effect does not happen just before landing, it happens only within about a wingspan from the ground, meaning you will only really feel it very close to touchdown.

The "approach" and a "Holding pattern" are two very different things. The approach is the procedure used to get to the runway. A holding pattern is a racetrack-shaped pattern that planes go into when they have to wait for further clearance.

During an approach in low visibility, the ATC is not a set of "extra eyes". Everything is just about the same for the Air Traffic Controller, and it's up to the pilots to land the plane properly.

Please, check your facts and stop just spewing nonsense about a topic you know nothing about.
