为什么乘坐飞机时手机要调成飞行模式？真实原因是……

坐飞机时会被要求将手机调成飞行模式，因为在飞机上使用手机会对飞行产生干扰，那么这种干扰具体指的是什么呢？

坐飞机时会被要求将手机关机或调成飞行模式，因为在飞机上使用手机会对飞行产生干扰，尤其是起飞和降落的时候，那么这种干扰具体指的是什么呢？来看看这篇干货吧。

We all know the routine by heart: “Please ensure your seats are in the upright position, tray tables stowed, window shades are up, laptops are stored in the overhead bins and electronic devices are set to flight mode.”

这句常规提醒我们都烂熟于心：“请确保您的座椅靠背垂直，餐桌和遮光板收起，笔记本电脑放在头顶的行李架上，手机调成飞行模式。”

Now, the first four are reasonable, right? Window shades need to be up so we can see if there’s an emergency, such as fire. Tray tables need to be stowed and seats upright so we can get out of the row quickly. Laptops can become projectiles in an emergency, as the seat back pockets are not strong enough to contain them.

前几个要求都很合理，不是吗？遮光板收起，我们才能看见起火等紧急状况。餐桌收起，座椅垂直，我们才能迅速离开座位。在发生紧急情况时笔记本电脑会变成乱飞的抛射物，因为椅背的袋子不够牢固。

And mobile phones need to be set to flight mode so they can’t cause an emergency for the airplane, right? Well, it depends whom you ask.

还有，手机需要调成飞行模式，这样才不会引发飞机紧急事故，对吗？这得看你问谁了。
