Extreme Cold Weather and Field Strength Testing of Engineered Material Arresting Systems (EMAS)

The Engineered Material Arresting System (EMAS) was jointly developed by the Federal Aviation Administration (FAA), The Port Authority of New York and New Jersey (PANYNJ), and Engineered Arresting Systems Corporation (ESCO-ZA) in the 1990’s as an alternate means of providing overrun safety when the mandated 1,000-foot-long Runway Safety Area (RSA) could not be economically achieved. The current EMAS system, EMASMAX®, manufactured (ESCO-ZA), is currently the only system that meets the requirements of FAA Advisory Circular AC150/5220-22A and is installed at 30 airports in the U.S. To date, the system has successfully arrested six overrunning aircraft, and has proven to be a reliable, efficient remedy for length-deficient runway end safety areas. Due to a lack of historical data, there have been some questions regarding EMAS’ long-term durability. In particular, there was of a lack of data regarding the ability of the system to maintain performance and survive for up to 20 years in extreme cold environments, or any quantitative method to evaluate the condition of the installed systems. This paper discusses two studies conducted by the FAA and ESCO-ZA to answer these questions: Extreme Cold Weather Testing and Development of a Field Strength Test Method. The results of the cold weather study have shown that EMAS is unaffected by extreme cold and temperature cycling, and can be expected to be durable for up to 20 years or more in extreme cold climates, while the development and certification of a field test method now provides a way to test the viability of installed beds. Combined, these studies result in a higher confidence that properly-maintained EMAS systems can survive harsh runway environments for up 20 years.
