DO-297, Integrated Modular Avionics (IMA) Development Guidance and Certification Considerations provides guidance for IMA systems, including partitioning considerations. Modern avionics systems are typically based on computer processors with sufficient performance to run multiple flight applications simultaneously, such as flight management, navigation, communications, and more. In previous generations of avionics, such functions were segregated to distinct (i.e., federated) computing hardware so that there was no interactions between them. Once integrated on a single processor, the safety of such systems must be assured, by verifying with high confidence that each independent function is partitioned from the others. [1] This modular approach is not only good software engineering practice but also supports incremental certification for software functions that are added in the future.[2], [3]
The FAA, EASA and other certification authorities indicate the DO-297 standard as one means to obtain airworthiness approval of IMA systems. For example, the FAA Advisory Circular (AC) 20-170[4] refers to DO-297. The document is published by RTCA, Incorporated, in a joint effort with EUROCAE, completed in November 2005. Along with ARINC 653 and DO-248, the DO-297 standard guides "Safety of flight for IMA systems"[5] DO-297 provides specific guidance for the stakeholders, defining the following roles[6]
- platform and module suppliers
- application suppliers
- IMA system
- integrator
- certification applicant
- maintenance organization
- certification authority.
History
The standard was significant because it formalized the use of more powerful computing hardware to host multiple software functions of differing safety-criticality. Without such formal recognition, the goals of reduced Size, Weight, and Power (SWaP) that can be achieved by IMA architectures are unachievable since such systems could not be flight certified. The lessons learned in certifying early approaches to IMA in commercial aircraft such as the Boeing 787 Dreamliner and the Airbus A380 helped inform the development of the standard.[7]
