Abstract

This article describes one of the approaches to functional and data exchange architecture of airborne distributed computer system (ADCS) for integrated flight-control systems (IFCS) to realize the fail-save requirement for airborne flight-control systems. The technical figure of fail-save ADCS for typed integrated flight-control systems (IFCS) for long-range civil aircraft was generally developed. To provide the required reliability control of integrated flight-control systems (IFCS) and designed level of flight operating safety the new principles of fail-save software development and rearrangement of its functional modes in case of failure were formed.
