Integrated modular avionics (IMA) and DO-297 are currently the analysis methods in the aerospace domain.
These techniques offer notions for the development and certification of the potential system architectures in the future. IMA is in fact an architectural technique containing various hosts linked together by a safety-critical channel system.
DO-297 contains guidance for Integrated Modular Avionics (IMA) developers as well as application developers, integrators, certification applicants. It also contains guidance for those involved in the approval and continued airworthiness of IMA systems in civil certification projects.
Along with ARINC 653 and DO-248, the DO-297 standard guides “Safety of flight for IMA systems” DO-297 provides specific guidance for the stakeholders, defining roles, such as:
- platform and module suppliers
- application suppliers
- IMA system
- integrator
- certification applicant
- maintenance organization
- certification authority.
The DO-297 standard formalizes the use of more powerful computing hardware to host multiple software functions of mixed safety-criticality.
IMA produces benefits of reduced Size, Weight and Power (SWaP) by integrating into a single computing platform software functions that were formerly on separate (federated) computing systems.
The standard describes how safety is maintained through the isolation provided by a partitioning environment, ensuring that independent functions cannot adversely impact one another’s behavior.
