飞机客舱为何会在降落时调弱舱内灯光？
语航学苑·科普在线
大家在飞机快要降落的时候，就会听到广播提示我们打开遮光板，同时会调整机舱里的灯光，那大家知道，为什么要调暗客舱光线吗？
When the plane is about to land, we will hear the radio prompt us to pull up airplane window shades and adjust the lights in the cabin. Do you know why we are supposed to dim the cabin light?
其实，调弱舱内灯光可不仅仅是用来方便乘客睡觉的！关闭客舱灯光有助于保持乘客的视觉适应，特别是在夜间起飞或降落时，外部黑暗可能会很强烈，乘客需要适应相对低亮度的外部环境。当飞机在夜晚准备降落时，机舱内的灯光就会调暗，这样降落后，乘客在下飞机时，眼睛就很容易适应夜晚外面的光线强度，可以更清楚地看到外面的情况，找到适合的逃生路线。我们在飞机降落前打开遮光板也是一个道理。
In fact, dimming cabin lighting is not just used for passengers to sleep. Turning off or dimming cabin lights helps keep passengers visually adapted, especially during night take-off or landing, when external darkness can be intense and passengers need to adapt to a relatively low brightness external environment. When the plane is ready to land at night, the lights in the cabin will be dimmed, so that after landing, when passengers get off the plane, their eyes can easily adapt to the light intensity outside of the night, and they can see the situation outside more clearly and find a suitable escape route. It's the same thing when we open shades before the plane lands.
对乘客而言，调弱客舱灯光有助于减轻在突发情况下的恐慌感，乘客的焦点更容易集中在紧急情况的处理上。
For passengers, adjusting the weak cabin light can help reduce the sense of panic in an emergency, and passengers are more likely to focus on emergency handling.
调暗客舱灯光可以保证飞行的安全性和准确性，避免对飞行员的视线造成干扰，以及保障飞机的正常信号接受和传输。
Reducing the cabin lights can ensure the safety and accuracy of the flight, avoid interference to the pilot's line of sight, and ensure the normal signal acceptance and transmission of the aircraft.
当然，从保障飞行安全的角度出发，飞机降落时调弱客舱灯光也是很有必要的。飞机的起飞和降落是整个航程中最为危险的时刻，所以在降落时调暗客舱灯光，可以降低不必要的能耗，使发动机产生的能量主要用于提供飞机的动力，目的是为了确保飞机安全降落。
Of course, for ensuring flight safety, it is also necessary to weaken the cabin lights when landing. The take-off and landing of the aircraft are the most dangerous moments in the whole voyage, so to dim the cabin lights during the landing can reduce unnecessary energy consumption, so that the energy generated by the engine is mainly used to provide the power of the aircraft, in order to ensure the safe landing of the aircraft.
所以下次坐在飞机上，
客舱灯光调暗，
这可不仅仅是为了营造静谧的氛围，
而是一项旨在保护飞机上每个人的安全措施。
