SAE AIR4061C

SAE Aerospace Information Report (AIR) 4061 provides best practice guidelines for the integration of Engine Health Management (EHM) system functions within aircraft systems to include both its main engine(s) and any Auxiliary Power Unit(s) (APU). This document provides an overview of some of the functions EHM typically integrates, offers some system variations encountered with different aircraft, and suggests general considerations involved with integration. It presents a sample EHM parameter coverage matrix to show the types of parameters with which a typical EHM system might interface, offers insight into signal and data processing and retrieval, and offers a view of typical EHM parameter requirements by function. Where practical, this document delineates between military and commercial practices. The AIR4061B has been superseded by a completely new document, ARP5120, which provides guidance on how to develop and implement an integrated end-to-end health management system for gas turbine engine applications. ARP5120 consolidates SAE Aerospace Information Reports AIR1873, AIR4061B, AIR4175A, and AIR5120 into one document per the direction of the SAE E-32 committee. The original AIR4061B information was updated and transformed into ARP5120 so AIR4061B should be cancelled.
