Civil Aircraft Functional Reliability Requirements Capture and Decomposition

As the complexity of civil aircraft continues to increase, ensuring their reliability becomes more important. As a leading manufacturer of civil aircraft, there is necessary to accurately capture aircraft-level top-level requirements in order to meet stakeholder requirements. As a key part of aircraft reliability design assessment, functional reliability assessment is an important design methodology to improve the level of aircraft reliability and complements previous reliability efforts. Through functional reliability requirement capture and decomposition, it can help leading manufacturer to grasp aircraft functions and the impact of failure states, and facilitate the subsequent better development of system and equipment specifications. This paper describes the process and results of functional reliability requirements capture and decomposition to guide the implementation.
