I'm reading this paper about IMA (Integrated Modular Avionics) and I don't get the splitting of the development and integration procedure. In page 4 it says:
Airbus has to modify the conventional development processes and responsibilities. The IMA system development and integration procedure is split between
- the Avionic Module Supplier
- the Aircraft System Manufacturer
Who is the Aircraft System Manufacturer? Which is its function?
My doubt is principally about this paragraph that is few lines later:
The open IMA concept puts the assembler into the position of the IMA system integrator. The development responsibility for the single systems and their functions remains at the system manufacturers. The avionic module supplier provides “empty” IMA modules to both, the system manufacturers and to assembler. The system manufacturer applies the CPIOM for the local function implementation and qualification. The assembler, in turn integrates the own empty CPIOM with the ADCN on the aircraft in order to establish the basic computing resource for different system functions.
