人的视力范围有一定限度,在空中看到一架战斗机的平均距离是8千米左右,这是天气晴朗时的平均值。有雾、雨天、黄昏时候,能见度很差,看见的距离要大为减小。而且每个人的视力差别很大,有的飞行员可在20千米以外看到飞机,有的近到8千米也看不见。此外,还与飞机大小有很大关系,对于轰炸机可以看得远一些,人的肉眼还有一个特点,如果已看到飞机,一直盯住让飞机逐渐飞远则可在10多千米后才看不见。相反,在天空中找飞机,有时已飞到5千米距离还找不
The range of human vision has a certain limit, in the air to see a fighter average distance is about 8 km, which is the average when the weather is fine. Foggy, rainy, dusk, visibility is poor, to see the distance to be greatly reduced. And each person's vision varies greatly, and some pilots can see the aircraft 20 km away, and some can not see nearly 8 km. In addition, but also a great relationship with the size of the aircraft, the bomber can see farther, the naked eye there is a feature, if you have seen the aircraft, has been pegged to the aircraft gradually flies can be more than 10 km Can not see Instead, looking for an airplane in the sky, it has sometimes flown to a distance of 5 kilometers and still can not find it
