DO-297 Training Course – Hands-on

DO-297 Training, Integrated Modular Avionics (IMA) Development Guidance and Certification Considerations

DO-297 training provides with the concepts, theories, methods, and requirements to create, develop, and maintain an effective DO-297 guideline. DO-297 training course delivers the basics for creating and incorporating Integrated Modular Avionics (IMA) system and its relationship and RTCA/DO-297 guidance and certification considerations.

Integrated modular avionics (IMA) and DO-297 are presently the analysis methods in the aerospace domain. Such techniques offer notions for the development and certification of the potential system architectures in the future. In fact, IMA is an architectural technique containing various hosts linked together by a safety-critical channel system. Such communication system needs to deliver various features to give support to a modular and integrated architecture. DO-297, in particular, handles the modular certification that is a requirement for the certification of these architectures. The integration of the IMA system and the certification standard enables establishing effective procedures for development and certification where the process is fully supported by the features of the communication system. DO-297 training will discuss such features, the correlation between the IMA system, its main communication structure and the development and certification process.

The integrated modular avionic (IMA) structure, presented in different current civil aircrafts, signifies a real-time avionic system layer with several adjustable, reusable, and inter-functional hardware and software elements that are able to introduce a number of applications executing aircraft operations at various levels. DO-297 hands-on will discuss the fundamental knowledge of IMA conferring RTCA DO-297.
