Seeking the Proper Balance Between Simulation and Flight Test - Public Policy

This paper examines the past and present roles of modeling and simulation (M&S) in lieu of, or in support of, the developmental engineering flight testing of aircraft and airborne systems. However, it should be noted that much of the commentary also applies to space systems. It posits that both M&S and flight testing are essential for efficient and effective development of such systems. It demonstrates, however, that the proper balance of the two must be based on sound engineering and programmatic analysis of their respective capabilities, benefits and disadvantages. At this time such a rigorous evaluation is rare, contributing to demonstrated or potential testing mishaps, poor development methodology, cost and schedule impacts, and deficient systems. AIAA recommends that a methodology for guiding the disciplined balancing of M&S and flight testing be developed and promulgated to avoid these outcomes and improve the air and space vehicle development process. AIAA offers the expertise of its Flight Testing Technical Committee and applicable Technical Committees to aid in this development.
