This paper targets the deterministic modeling for availability and survivability evaluation of Avionics Display System through simulation on MATLAB using Markov Model. The modern day Glass cockpit are designed to use four Multi Functional Displays (MFDs) to provide information to pilots. This paper presents mainly about Markov modeling through simulation on MATLAB Version 7.7.0 (R2008b) for determining failure rate of MFDs. These MFDs are Line Replaceable Units (LRU). Avionics system's failure rate depends on reliability of 4 LRUs(MFDs) and their failure rates (λ). It is assumed that data is mirrored in all MFDs. With help of Markov Model on MATLAB, graphical analysis of failure rate over a period of long time can be simulated. “Analysis of Failure rate of Multi Function Display (MFD)” concludes that Failure Rate of the system works out to be 84.885 Failures / 106 Hrs.
