Frequently Asked Questions

The concept of integrated modular avionics came due to the huge advancements in the electronics industry, increased functional complexity in the avionics systems and need for smart integrated and modular systems. The concept of integrated modular avionics came in mid-90 due to huge investments made by the airline industries on more integrated platforms.  The basic concept behind IMA is sharing the common set of “cabinets” with ARINC 653 specifications that are connected simultaneously with other secondary equipment through number of multiple access network which are based on ARINC 664 specifications. Each cabinet is a high-power computing hub which substitutes a number of avionics applications. Each cabinet has an adequate processing and interface capability to maintain the required integration of avionics functionality. The system specific application software is designed to conform the appropriate standards of the application executive interface specification (APEX). Thus this application standard also allows the application software reusability on processors of diverse hardware designs.
