中国西部干线飞机颠簸分布规律分析

基于四川航空公司2006年的飞机颠簸资料,对以成都为枢纽中心的14条航线在巡航阶段产生的颠簸情况进行了分析。结果表明:在西部干线中,飞往西藏地区的航线飞机颠簸出现概率最高,春季的航线颠簸次数最多,秋季发生的颠簸次数最少;飞机颠簸的出现高度主要分布在7000~10000m高度范围内;西部干线上发生中-轻度颠簸的概率最高,其次是轻度颠簸,发生强烈颠簸的概率最小。 

Airplane Turbulence Distribution Analysis of Western Trunk Airlines in China

The paper is based on the aircraft-borne data from Sichuan airline during 2006.The authors analysis turbulence produces in the cruising phase distribution on 14 western routes which are around the airport of Chengdu.The research points out that the Tibet area occurs the largest probability of turbulence;the aircraft turbulence mainly appear in spring and the fall occur very few;aircraft turbulence mainly distribute between 7000m and 10000m altitude range;middle-light is the most high probability turbulence level,follow is light level and the probability of strong level is the most minimum.
