These systems include both internal diagnostic equipment referred to as built-intest (BIT) and external off-line test equipment. At the designing stage an adequate database to evaluate the quality of the BIT is the failure mode and effect analysis. In the paper various mathematical indices are suggested and constructed to quantify testability of avionic systems. The indices provide the needed flexibility for representing structural and reliability properties of the controlled system. Analytical model for evaluation BIT performance impact on the system\'s reliability is discussed. << 收起
