One of the most important system development issues facing developing new aerospace systems is how to comply with the complex design requirements and in the same time ensure compliance to the associated safety requirements. There is an increased need to develop complex and critical aerospace systems that depend on high integration between the Hardware and the Software to achieve efficiency and optimization. This level of complexity imposes significant challenge in complying and achieving the required level of safety. This paper addresses the safety challenges that are imposed by developing complex systems to fulfill critical functions with the focus on the common causes and the compliance to the Design Assurance Level. The design doesn’t only need to take in consideration assigning the proper Design Assurance Level for each function, but also provide immune against common cause errors. The paper will discuss different design cases to illustrate how incorporating the design and safety requirements in an early stage of the design is a key for a successful development.
