Abstract:
As aircraft systems become more complex the need to integrate software and hardware at different levels of abstraction becomes more important. For complex civil aircraft USA and Europe have reached a consensus in "Guidelines for Development of Civil Aircraft and Systems Development" in SAE ARP 4754A/ED-79. This document discusses the development of aircraft systems taking into account the overall aircraft operating environment and functions. This includes validation of requirements and verification of the design implementation for certification and product assurance. It provides practices for showing compliance with the regulations and serves to assist a company in developing and meeting its own internal standards by considering the guidelines in it. It focuses on the need for aircraft and system (both hardware and software) functional hazard assessment and safety analysis early in the complex system development process. For military aircraft system development, airworthiness qualification and safety assessment are often conducted too late in the development process. This results in the airworthiness process and the DOD acquisition process being incompatible for the acquisition of complex systems. The Department of Defense (DoD) needs to focus on the value a thing has over its useful life. This change will allow DOD to compete differing solutions and get the best value. The key to Value Based Acquisition (VBA) at the program level is the development of a value model that embodies key system design features, such as weight, manufacturing cost, reliability, and the like, as well as key acquisition concerns, such as cost and schedule. Once a quantitative value model has been defined, it can become the basis for contracting. This paper will propose how a combination of the Development Assurance (DA) civil aircraft approach in SAE ARP 4754A/ED-79 and a VBA approach can be combined for a DAVBA Approach for military planned VTOL Aircraft Development, such as Future Vertical Lift (FVL). An example of how the approach can be developed for a FVL baseline, the UH-60M Black Hawk Helicopter, will be presented.
