Technology Challenges Characterizing vehicle s degradation and capability in harsh environments. (temp, acoustic, etc.) Interpreting sensor information into vehicle s condition via diagnostics algorithms in near real-time. Integrating, managing and processing sensor data in real-time. Minimal turn-around time is achieved with the diagnostic tools for early identification, accurate assessment and timely maintenance of subsystem degradation during pre-flight and postflight Higher vehicle operation reliability is achieved by updating in-flight the vehicle s guidance and control system with its current capabilities and limitations Lower cost of operation is achieved with the prognostic tools to allow the repair & replace schedule to be integrated with the flight schedule
