Aircraft Gas Turbine Engine Health Management System Development and Integration Guide
ARP5120 provides recommended best practices, procedures, and technology to guide the physical and functional design, development, integration, verification, and validation of highly reliable Engine Health Management (EHM) systems for aircraft engines and Auxiliary Power Units (APUs). This SAE Aerospace Recommended Practice (ARP) also serves as a concise reference of considerations, approaches, activities, and requirements for producing the end-to-end engine health management system comprised of both on and off-board subsystems for the sensing, acquisition, analysis, detection, and data handling functions for EHM. These functions may also be used to effect continued operation or return to service decisions when demonstrated as compliant with the applicable airworthiness requirements defined by the responsible Aviation Authority. Where practical, this document delineates between military and commercial practices.
Rationale: The aviation industry uses Engine Health Management technologies to improve engine and aircraft reliability, availability and maintainability. This SAE Aerospace Recommended Practice (ARP) provides guidance on how to develop and implement an integrated end-to-end health management system for gas turbine engine applications. ARP5120 consolidates AIR1873, AIR4061B, AIR4175A, and AIR5120 into one document per the direction of the SAE E32 committee.
