根据2006年1-12月四川航空公司A320和A319飞机的机载QAR数据,对我国高原重要航线上飞机颠簸次数、强度和出现的概率进行了统计,分析了我国高原重要航线上飞机颠簸的出现规律。研究指出,在我国高原航线上,飞机颠簸主要出现在冬春季节,以成都为中心,以九黄、丽江、大理、昆明为弧线的扇形区域,是高原航线飞机颠簸主要发生区。飞机颠簸主要出现在飞机的起飞着陆阶段,颠簸强度越大,发生的概率越小。青藏高原航线上飞机颠簸出现的概率较小,而云贵高原航线上飞机颠簸出现的概率较大。
Based on the airborne QAR data of Sichuan Airlines A320 and A319 from January to December in 2006, the frequency, intensity and occurrence probability of aircraft jerk in the important routes on the plateau in China were analyzed. The occurrence of aircraft bumps in the important routes on the plateau of China was analyzed law. The study indicates that the aircraft bumpy mainly occurs in the winter and spring seasons on the plateau routes in China. The fan-shaped area with Chengdu as the center and Jiulou, Lijiang, Dali and Kunming as the arcs is the main area where aircraft bumps occur in the plateau routes. Aircraft bumps mainly in the take-off and landing phase of the aircraft, bump strength, the smaller the probability of occurrence. The probability of aircraft bump on the Qinghai-Tibet Plateau is small, while the probability of aircraft bump on the Yun-Gui Plateau route is higher.
