Keywords: avionics systems

The technological growth of ‘avionics systems’ has outpaced the service-life of the aircraft, resulting in avionics upgrade as a preferred cost-effective option to new design. Mid-life upgrade of “avionics systems” by state-of-the-art mission systems has been a challenging engineering task. The complexity of avionics upgrade process is due to the design rigidity of avionics systems architecture. An avionics architecture with growth potential is required to optimise avionics upgrade with state-of-the-art systems. In this paper, the overview of system framework for the development of avionics architecture with growth potential is presented, followed by the detailed discussion on the ‘Avionics Architecture Analysis’ (AAA) module. The AAA module considers various design parameters in identifying the architectural parameters of existing avionics.
