Background
The Federal Aviation Administration (FAA) is actively working to improve runway safety areas (RSAs) at commercial service airports by the end of 2015. The RSA is typically 500 feet wide and extends 1,000 feet beyond each end of the runway. It provides a graded area in the event that an aircraft overruns, undershoots, or veers off the side of the runway. Many airports were built before the current 1,000-foot RSA standard was adopted approximately 20 years ago. In some cases, it is not practicable to achieve the full standard RSA because there may be a lack of available land. There also may be obstacles such as bodies of water, highways, railroads, and populated areas or severe drop-off of terrain.
The FAA began conducting research in the 1990s to determine how to improve safety at airports where the full RSA cannot be obtained. Working in concert with the University of Dayton, the Port Authority of New York and New Jersey, and the Engineered Arresting Systems Corporation (ESCO) of Logan Township, NJ, a new technology emerged to safely arrest overrunning aircraft. EMAS uses crushable concrete placed at the end of a runway to stop an aircraft that overruns the runway. The tires of the aircraft sink into the lightweight concrete and the aircraft is decelerated as it rolls through the material.
Benefits of the EMAS Technology
The EMAS technology improves safety benefits in cases where land is not available, or not possible to have the standard 1,000-foot overrun. A standard EMAS installation extends 600 feet from the end of the runway. An EMAS arrestor bed can be installed to help slow or stop an aircraft that overruns the runway, even if less than 600 feet of land is available.
Current FAA Initiatives
The Office of Airports 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. Of the approximately 1,000 RSAs at these airports, an estimated 65 percent have been improved to full standards, and an estimated 90 percent have been improved to the extent practicable, not including the relocation of FAA-owned navigational equipment.
Many of the EMAS beds installed prior to 2006 need periodic re-painting to maintain the integrity and functionality of the bed. ESCO has developed improved plastic seal coating for EMAS beds. This new coating should eliminate the need for the periodic re-painting.
EMAS Arrestments
To date, there have been nine incidents where EMAS has safely stopped nine overrunning aircraft with a total of 243 crew and passengers aboard those flights.

EMAS Installations
Currently, EMAS is installed at 74 runway ends at 47 airports in the United States, with plans to install 13 EMAS systems at seven additional U.S. airports.
