航班起飞过程的风险识别与控制

飞机起飞阶段是事故多发阶段,为了进行风险识别与控制,设计了定性判别方法和定量计算仿真算法,并以具体飞机坠毁事故为例分析了安全裕度.分别计算了飞机冲出跑道的速度、距离和逃生时间.中断起飞的速度与时间,是火灾发生后的判断关键,也构成了飞机起飞事故的裕度.结果表明,中断起飞的安全裕度比坠毁的大,且关于中断起飞的规定有矛盾之处;用于逃生的90 s规则高于中断起飞的决断速度的限制规定.该分析方法为处理危急时刻的两难决策问题提供了理论指导.

Risk recognizing and control for flight takeoff

The present paper is aimed to introduce a quantitative and qualitative simulation algorithm developed by its authors for observing and calculation of the velocity and the taking-off distance. It is well-known that there have been exiting or hard-nuts or troubles in risk-recognition and control in the takeoff stage of the airliners,which in turn may lead to disastrous accidents. In hoping to work out an approach to more efficiently recognize the hazards on the high-speed running,we have done a lot of qualita...
