METS meets the F-15E supportability challenge

The Mobile Electronic Test Set (METS) F-15 avionics intermediate shop (AIS) automatic test equipment (ATE) is described. METS takes advantage of the stimuli/measurement capability for a printed circuit board available for portable testers. Because METS uses six parallel high-speed microprocessors and distributed processing techniques, it provides a real-time multitasking test environment. The extensive built-in testing (BIT) capability of each unit is utilized by METS to assist in the fault isolation. The evolution of F-15 AIS ATE to the METS is presented as a function of a combination of changes in US Air Force operational requirements and improvements in line replaceable unit (LRU) testability.<
