Table 1. Effects of Mode-5 Shaping Constant A on Atlas IIA Risks B= 1,000 Percent of Mode-5 IPs Uprange 28.6 Casualty Expectancv (x 10°') inside ILLs Modes Total for all Modes 246 259.9 Constant A 2.5 3.0 3.5 4.0 20.7 14.6 10.0 136 149.4 58.9 72.7 30.5 44.3 The results in·the third column are directly proportional to the probability that a Mode­ 5 failure occurs. For the Atlas IIA analysis, a value of 1/200 = 0.005 was assumed. Case 2: Risk Contours for Atlas IIAS Definitions of Flight Hazard Area and Flight Caution Area may be based on the risk contours for inner-ear injury. Constant A can have a significant effect on the location of the 10-6 contour, as illustrated in Figure 2 and Figure 3 for the Atlas IIAS. For these figures, the Mode-5 absolute probability of occurrence was 0.005, constant A was 3.0 and 3.5, and constant B was 1000. 9/10/96 10 RTI
