众所周知,低能几尢度(大雾、降雪、沙尘暴、浓烟等)严重地影响着航空器的起飞和着陆,是酿成飞行事故和航班延误最常几尢的原因之一。 1993年11月13日21时(北京时,下同)后,首都机场出现大雾,能见度小于100m,器测跑道视程RVR显示MM200(最小显示极限),全部飞行活动停止。直至14日10时以后能见度稍有好转,维持在300～500m之
It is well-known that the low energy levels (fog, snowfall, sandstorms, smoke, etc.) seriously affect the take-off and landing of aircraft and are one of the most common causes of flight delays and flight delays. At 21:00 on November 13, 1993 (at the same time in Beijing, the same below), the fog appeared at the Capital Airport with a visibility of less than 100m. The RVR of the measured runway showed MM200 (minimum display limit) and all flight activities were stopped. Visibility improved slightly until 10 o’clock on the 14th, maintained at 300 ~ 500m
