Product Code:SAE ARP4294
Title:Data Formats and Practices for Life Cycle Cost Information
Issuing Committee:E-35 Prop Economics For Acquisition And Ownership Committee
Scope: This SAE Aerospace Recommended Practice (ARP) 4294 is directed at life cycle cost (LCC) analysis of aerospace propulsion systems and supplements AIR1939. Specific topics addressed by ARP4294 are listed below: a) propulsion system LCC element structure; b) information exchange and relationship with: 1) aircraft manufacturer, 2) equipment suppliers, and 3) customer; c) the relationship of the LCC element structure to work breakdown structures; d) the relationship between LCC analysis and other related disciplines (e.g., technical (performance analysis, weight control, component lives), reliability, availability and maintainability (RAM), integrated logistic support (ILS), production and finance); and e) classification of the accuracy and applicability of LCC assessments.
