Figure 27 shows the percentages of malfunction-turn impacts in 5° sectors for no breakup and for breakup qa’s of 20,000, 10,000, and 5,000 deg-Ib/: ft. For B= 1,000, theoretical Mode-5 impact distributions are also plotted in the figure using best-fit values of A. This value of B was chosen since it is currently used by RTI in making launch-area risk studies for 45SW/SE. Within the sectors from +60° to +180°, where most population centers are located, data fits are reasonably good. As seen in the next figure, the divergence for the no-breakup case can be greatly reduced by'selecting other values for B and A. 100 10 Percent in 5-deg sector (%) 0.1 i i i i i i i 0 20 40 60 80 100 120 140 160 180 Angle From Flight Path (deg) Figure 27.
