Rationale:This Aerospace Information Report (AIR) has been superseded by the document AIR7999, “Diagnostic and Prognostic Metrics for Aerospace Propulsion Health Management Systems.” AIR7999 consolidates and expands upon the contents of this document (AIR4985) plus AIR5909, “Prognostic Metrics for Engine Health Management Systems.” As such, AIR7999 provides a single comprehensive document on diagnostic and prognostic metrics for aerospace propulsion health management systems making the contents of AIR4985 and AIR5909 redundant and unnecessary. This document consolidation strategy was agreed to by the SAE E-32 Aerospace Propulsion Systems Health Management Committee as part of the Committee’s Master Plan.
Also known as: SAE AIR 4985
