Description / Abstract: DO-297 contains guidance for Integrated Modular Avionics (IMA) developers, application developers, integrators, certification applicants, and those involved in the approval and continued airworthiness of IMA systems in civil certification projects. It is focused on IMA-specific aspects of design assurance. IMA is described as a shared set of flexible, reusable, and interoperable hardware and software resources that, when integrated, form a platform that provides services, designed and verified to a defined set of requirements, to host applications performing aircraft functions. The primary industry-accepted guidance for satisfying airworthiness requirements for IMA components is included and it describes application properties as they relate to their integration with a platform.
