Future Vertical Lift Airworthiness Certification - Should it be based on A Civil Aviation Functional Safety Certification Standard?
Authors / Details: Daniel Schrage, Georgia TechAbstract
As integration of software and hardware plays a bigger role in the design of complex systems and system of systems the terms Cyber Physical System (CPS) and Cyber Physical Vehicle System (CPVS) are used to describe this software enabled control (SEC) paradigm shift. A CPS is the next generation of system that requires tight integration of computing, communication, and control technologies to achieve stability, performance, reliability, robustness, and efficiency in dealing with physical systems of many application domains1. Pertaining to vehicle systems, a CPVS, ranging from automobile to aircraft and marine craft, is composed of tightly-coupled locomotion, computational and communication components. This SEC tight coupling has a major impact on the development and certification for future aircraft systems, such as Future Vehicle Lift (FVL). In the civil aircraft sector this tight SEC coupling is being addressed by new or substantially updated guidelines for civil aircraft and systems development, such as DO 297 and ARP 4754A. The tight interaction with ARP 4761 and dependence between certification and safety assessment at different levels, e.g. functional and item, are promoted through the use of supporting Development Assurance Levels (DALs). While in the military aircraft sector some attempts have been made to keep pace with this transition to CPVS tight coupling, the question is will this be adequate or relevant for FVL? Following an introduction, this paper will start with a review of functional safety certification standards and their evolution into the civil aircraft sector. This will be followed by a review of military aircraft airworthiness qualification standards. Finally, whether they are sufficient for future aircraft development, such as FVL, will be questioned.
