Abstract: The Concorde aircraft accident decision is studied in this paper under the view of system safety,with the simulation for the overrun speed and time.It is believed in this paper that to continue to climb when catching fire is the worst decision with the heaviest lost in lives.If it Rejected Takeoff (RTO),the consequence would be slighter,saving many lives.The program is complied in this paper to show the overrun speed and time for the Concorde aircraft to evacuation in RTO under high running velocity.The safety margin is consisted of speed and time,regarded in this paper.The result shows that the 90 second regulation is a key element to obey to make decision after V1.The margin of safety may be reached at the RTO decision with the higher survival rate of passengers.The analysis method developed in this paper may give guide to suppress the dangerous situation in flight for other aircrafts and regulations.The time constrain of 90 seconds has the higher order than the V1 decision regulation.

摘要: 为协和飞机的坠毁事故是由于当时没有选择中断起飞而造成的最差决策,损失最大且没有救援的可能。如果当时选择中断起飞决策,其安全裕度会提高,结果可能会好一些。为了说明这个问题,设计了计算程序,分别计算冲出跑道的速度、距离和逃生时间。安全时间是火灾发生后的判断关键,时间与速度,构成了这次事故的裕度。从计算结果可以看出,安全裕度较大。用于逃生的90秒规则,具有很高的安全限制,它高于中断起飞的决断速度规定。程序计算结果说明选择中断起飞,损失可以减少,生存率可以提高。该分析方法为处理危机时刻的两难决策问题提供了理论指导。
