TPS evolution and test software development in the two-level maintenance environment

Abstract

Two-level maintenance and BIT/software intensive line replaceable module architectures will be driven by the dual imperatives of harmonizing online UUT BIT/BIST (unit under test built-in test/built-in self-test) with offline ATS/TPS (automatic test system/test program set) test capability and of improving the approach to software specification and development in both areas. It is suggested that these imperatives can be satisfied through the introduction of a consolidated support package (CSP) concept that is derived from, but replaces, the currently used TPS. The CSP, which can be used as a key element in the acquisition of demonstrable integrated support capability, is an identifiable entity developed in accordance with a generic standard such as DOD-STD-2167A, but tailored by maintenance-specific standards to test software needs.<>
