Method to Allocate Vehicle Health Management Analytics to Subsystems for Maintenance Credit

Airworthiness Approval of a Health and Usage Monitoring System as described in Miscellaneous Guidance 15 of the FAA's Advisory Circular 27-1B requires emphasis be placed on the certification requirements and their relationship to the design solution as it matures during the systems development process. A candidate Integrated Vehicle Health Management (IVHM) System-of-Systems (SoS) architecture is proposed in which the vertical lift segment and automated information systems are integrated with the sustainment processes. Next generation ground and support processes are introduced and methods used to substantiate reliability, availability, maintainability, and cost (RAM-C) using discrete event simulations based on market specific design reference missions are examined. A step-by-step system design process, including techniques to allocate data manipulation, condition monitoring, health assessments, and prognostics functionality to on-board and off-board system segments from concept design through sustainment with emphasis on certification is presented.
