Modular Architecture technologies dates back to the 1990’s. The first modular solution – The Common Integrated Processor – was introduced on the F-22. Civil applications started with the AIMS platform on the B777. Further came the notion of openness introducing interface standardization and a multi supplier approach.
Benefits of a Modular Open Architecture in aviation is undisputable: from weight reductions (to the tune of 1000s of pounds), to spares pools optimization, all the way through to the ability to evolve functionality during the life of the aircraft. Two common perceptions: (i) this operational efficiency comes at a significant price and (ii) developing a system using an IMA architecture adds significant complexity (and cost) during the development and certification process. This tutorial intends to demystify the notions of Modular Open Architecture and Integrated Modular Avionics System. It will also highlight what are the key technical traps as well as the industrial challenges requiring careful consideration during a modular architecture development and certification.
