The Federal Aviation Administration (FAA) requires airfields to have a 1000-ft. runway safety area beyond the design runway length for aircraft overruns. However, at many locations, this requirement cannot be satisfied because of natural or man-made barriers. An alternative solution to the 1000-ft. runway extension is to use an engineered material arresting system (EMAS). An EMAS system is designed to significantly reduce an aircraft's stopping distance during an aircraft overrun without significant passenger discomfort or aircraft damage. The FAA computer code ARRESTOR is used in this study to evaluate aircraft stopping distance as a function of characteristic parameters that are typically considered in an EMAS design. This study considers the sensitivity of stopping distance as a function of arrestor material compressive strength behavior, aircraft characteristics, and aircraft type for a given arrestor bed geometry. During this study, 121 computer overrun simulations are performed to develop a sensitivity study of the EMAS. The sensitivity of aircraft stopping distance is examined as a function of a specific study parameter (arrestor material characteristic or aircraft characteristic). Results are normalized using typical design parameters as a basis. Results for stopping distance are summarized as plots as a function of variability in material strength. The sensitivity analysis conducted in this work identifies critical EMAS design parameters and therefore, provides a means to optimize an EMAS design.
