ARINC specification 653 based real-time software engineering

This paper reports successive steps of a real-time avionic pitch control application creation. The application structure follows a new real-time systems development profile published in ARINC specification 653. The paper mentions some main ARINC specification 653 features and shows the subsequent application creation levels: control system units distribution, timing requirements definition, application implementation and tests. It describes the author's experience gained during an avionic hard real-time system development and focuses on real-time software engineering details of the application creation.
