This SAE Aerospace Recommended Practice (ARP) examines a comprehensive construct of an Integrated Vehicle Health Management (IVHM) capability. This document provides a top-level view of the concepts, technology, and implementation practices associated with IVHM. This keystone document of the SAE HM-1 Committee is not intended as a legal document and does not provide detailed implementation steps, but does address general implementation concerns and potential benefits.

This SAE Aerospace Recommended Practice (ARP) examines a comprehensive construct of an Integrated Vehicle Health Management (IVHM) capability. This document provides a top-level view of the concepts, technology, and implementation practices associated with IVHM. This keystone document of the SAE HM-1 Committee is not intended as a legal document and does not provide detailed implementation steps, but does address general implementation concerns and potential benefits. Figure 1 provides a document flow map of the documents currently in work or planned by the Committee. The documents shown below will provide the recommended practices for IVHM implementation. This document map reflects the current SAE IVHM document configuration as of the date of publication. Future documents that are released will be included in the flow map in future updates of this document. An indication of the scope of IVHM is diagrammed in Figure 2.

This SAE Aerospace Recommended Practice (ARP) provides guidance when creating integrated vehicle health management (IVHM) system architecture. IVHM covers a vehicle’s monitoring and data processing functions inherent within its sub-systems, and the tools and processes used to manage and restore the vehicle health. These guidelines are drawn from experience within both defense and commercial IVHM initiatives and implementations. The document identifies a step-by-step methodology to expose functional and non-functional requirements, mature the architecture and support organizational business goals and objectives.

This Aerospace Recommended Practice (ARP) provides guidance on developing requirements for systems that include Integrated Vehicle Health Management (IVHM) capability [REF1], [REF18]. IVHM is increasingly being implemented on military and commercial aircraft. Some examples include the F-35 Joint Strike Fighter (JSF) [REF1] and the AH-64 Apache [REF3] in the military domain, and the B787 [REF4] and A350XWB [REF5] in the commercial domain. This document provides a systematic approach for developing requirements related to the IVHM capabilities of a vehicle system. This document is not intended to repeat general guidelines on good requirements writing [REF13], [REF20]. Instead, the focus is on the unique elements, which need to be considered for IVHM and the resulting specific guidelines that will help define better requirements and hence better systems. The multi-faceted nature of IVHM should include the process of requirements gathering.
