Abstract
Embodiments of the present invention provide a prognostics and health management (PHM) system for one or more electronic, electro-mechanical, pneudraulic and mechanical devices of an aircraft, and associated diagnostic methods and computer program products. The system includes a tangible and non-transitory memory preloaded with prognostics and health management signature data; one or more sensors that are adapted to monitor the one or more devices; and a logic device adapted to calculate an address and to access the tangible and non-transitory memory using the calculated address in real time. One or more portions of the calculated address are responsive to one or more parameter values associated with the sensors so that sensor parameter data determines the address into the memory. In the PHM system, the logic device is further adapted to generate a PHM alert in real time responsive to a value of the PHM signature data accessed at the address.
