F =0.98. The conditional probability of a Mode-5 response was assumed to be 0.08 (from the last line of Table 15), so the absolute probability was 0.031 x 0.08 = 0.0025. For the remaining cases in Table 21, the same assumptions were made for the total failure probability and for the probability of a Mode-5 response. • Table 21 .

Even for values of B as different as 1,000 and 5,000,000, the Mode-5 risks (qa =5,000) differ by only 12%. This difference drops for all other values of B. In fact, the differences probably have more to do with the choice of A than to any inherent difference in results due to the choice of B. For Atlas IIAS, 24% of the total Mode-5 Ee in the launch area is due to one population center, and 51 % of the total Ee to only five population centers (see page 49 of Ref [3]). If values of A had been chosen so that theoretical distributions and random-attitude-turn distributions more nearly matched for the radial directions to these population centers, 9/10/96 50 RTI
Vision Description (EN)
Technical analysis page documenting section 6.3.2 Launch-Area Mode-5 Risks. The page opens with a narrative paragraph explaining failure probability methodology and Mode-5 response conditional probabilities, followed by Table 21 'Shaping Constants and Related Risks for Delta-CEII', which presents structured numerical data across six columns with approximately 18 rows. The table rows contain failure probability scenarios with varying parameters (Ps, TB duration in seconds, Breakup loads, and constants B and A). Below the table are three paragraphs of technical discussion analyzing the sensitivity of Mode-5 risks to parameter A and B values, and risk distribution across population centers. Footer indicates date 9/10/96, page number 64, and RTI attribution. No visible classification markings, redactions, or signatures.
Descrição Vision (PT-BR)
Página de análise técnica documentando a seção 6.3.2 Riscos de Modo-5 na Área de Lançamento. A página abre com um parágrafo narrativo explicando a metodologia de probabilidade de falha e as probabilidades condicionais de resposta de Modo-5, seguido pela Tabela 21 'Constantes de Configuração e Riscos Relacionados para Delta-CEII', que apresenta dados numéricos estruturados em seis colunas com aproximadamente 18 linhas. As linhas da tabela contêm cenários de probabilidade de falha com parâmetros variados (Ps, duração de TB em segundos, cargas de falha, e constantes B e A). Abaixo da tabela há três parágrafos de discussão técnica analisando a sensibilidade dos riscos de Modo-5 aos valores dos parâmetros A e B, e distribuição de risco em centros populacionais.
