Engineered Material Arresting System (EMAS) Background The Federal Aviation Administration (FAA) requires that commercial airports, regulated under Part 139 safety rules, have astandard Runway Safety Area (RSA) where possible. At most commercial airports the RSA is500 feetwide and extends 1,000 feet beyond each end ofthe runway. The FAA hasthis requirement inthe event that an aircraft overruns, undershoots, orveers offthe side ofthe runway. The most dangerous ofthese incidents are overruns, but since many airports were built before the 1,OOO-foot RSA length was adopted some 20 years ago, the area beyond the end ofthe runway iswhere many airports cannot achieve the full standard RSA. This isdue to obstacles such as bodies ofwater, highways, railroads and populated areas orsevere drop-off ofterrain. The FAA has a high-priority program to enhance safety by upgrading the RSAs atcommercial airports and provide federal funding to support those upgrades. However, itstill may not be practical for some airports to achieve the standard RSA. The FAA, knowing that itwould be difficult to achieve astandard RSA atevery airport, began conducting research inthe 1990s to determine how to ensure maximum safety atairports where the full RSA cannot be obtained. Working in concert with the University of Dayton, the PortAuthority of NewYork and New Jersey, and the Engineered Arresting Systems Corporation (ESCO) of Logan Township, NJ, a newtechnology emerged to provide an added measure ofsafety. An Engineered Materials Arresting System (EMAS) uses materials ofclosely controlled strength and density placed atthe end ofa runway to stop orgreatly slow an aircraft that overruns the runway. The best material found to date isa lightweight, crushable concrete. When an aircraft rolls into an EMAS arrestor bed, the tires ofthe aircraft sink into the lightweight concrete and the aircraft isdecelerated by having to roll through the material. Benefits of the EMAS Technology The EMAS technology provides safety benefits in cases where land is not available, where itwould bevery expensive forthe airport sponsor to buythe land offthe end ofthe runway, orwhere it is otherwise not possible to have the standard 1,OOO-foot overrun. A standard EMAS installation extends 600 feet from the end ofthe runway. An EMAS arrestor bed can still be installed to help slow orstop an aircraft that overruns the runway, even if lessthan 600 feet of land isavailable. Current FAA Initiatives The Office ofAirports prepared an RSA improvement plan for the runways at approximately 575 commercial airports in 2005. This plan allows the agency to track the progress and to direct federal funds for making all practicable improvements, including the use of EMAS technology. Presently, the EMAS system developed by ESCO using crushable concrete isthe only system that meets the FAA standard. However, FAA isconducting research through theAirport Cooperative Research Program (project number 07-03) thatwill examine alternatives to the existing approved system. The results ofthis effort are expected in2009. More information onthe project can be found atthe Transportation Research Board web site athttpJ/WwwJf!;l.org/CRP/ACRP/ACRP.asp. Many ofthe EMAS beds installed prior to 2006 need periodic re-painting to maintain the integrity and functionality ofthe bed. FAA isworking with ESCO to develop a retrofit ofthe older beds with

plastic lids that are used on newer installations. This lid should eliminate the need forthe periodic re-painting. EMASArrestments To date, there have been four incidents where the technology has worked successfully to arrest aircraft which overrun the runway and in several cases has prevented injury to passengers and damage tothe aircraft. May 1999: A Saab 340 commuter aircraft overran the runway atJFK
"' May2003: Gemini Cargo MD-11 overran the runway atJFK January 2005: A Boeing 747 overran the runway atJFK

m July 2006: Mystere Falcon 900 airplane overran the runway atthe Greenville Downtown Airport in South Carolina EMAS Installations Currently, EMAS is installed at30 runway ends at21 airports in the United Stated, with plans to install 14 EMAS systems at 8additional US. airports.
