This correspondence presents a reliability model for a redundant flight computer system with. standby sparing, taking into account various mission abort strategies. A mission rule to initiate a mission abort after a predetermined number of detected computer failures and to return to earth with the remaining computers is shown to result in: 1) little improvement of crew safety unless computer error coverage is nearly perfect, and 2) significant degradation in mission success whenever coverage is high.
Aerospace computers, computer system reliability modeling, coverage, crew safety probability, mission abort strategies, mission success probability.
