  • VOA慢速听写:为何飞机在高温天气无法飞行

    1zwl366 2017-07-10 09:00

    新闻背景:
    有时,飞机在极度高温的天气中是很难起飞的。不过,原因并不是温度或空气湿度。阻碍飞机飞行的是空气密度。天气炎热空气较稀薄。空气稀薄会影响飞机正常起飞和降落。这种情况对于小型飞机更为常见。本周早些时候,美国西南部超50多班飞机因为高温被迫停飞。那里的气温已飙升至49摄氏度。
    It is sometimes more difficult to get airplanes off the ground in extremely hot weather. But the problem is not the temperature itself or the humidity.
    It is the air density that can get in the way.

    That is why more than 50 flights were canceled in the southwestern United States earlier this week. Temperatures there have climbed to 49 degrees Celsius.

    hotter air gets thinner, thinner air makes it difficult for planes to leave or land safely.

    Hotter air gets thinner. Thinner air makes it more difficult for planes to leave and land safely. This is especially the case with small planes.
