Background
The Federal Aviation Administration (FAA) actively worked 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, now Runway Safe Inc of Logan Township, NJ, a new technology emerged to safely arrest overrunning aircraft. EMAS uses crushable material placed at the end of a runway to stop an aircraft that overruns the runway. The tires of the aircraft sink into the lightweight material 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 can stop an aircraft from overrunning the runway at approximately 80 miles per hour. An EMAS arrestor bed can be installed to help slow or stop an aircraft that overruns the runway, even if less than a standard RSA length is available.
EMAS Manufacturers
Runway Safe acquired the EMASMAX product range from ESCO as of February 2020. Runway Safe is the sole manufacturer of EMAS products that meet the FAA requirements of advisory circular 150-5220-22B, “Engineered Materials Arresting Systems for Aircraft Overruns.” Currently, Runway Safe has two EMAS systems, the cellular concrete block system called EMASMAX and the silica foam system called greenEMAS.
The FAA must still review and approve each EMAS installation.
EMASMAX® is the latest, most durable version of Runway Safe’s block based EMAS, developed with and technically accepted by the FAA. EMASMAX arrestor beds are composed of blocks of lightweight, crushable cellular cement material designed to safely stop airplanes that overshoot runways.
Runway Safe’s greenEMAS® is a foamed silica bed which is made from recycled glass and is contained within a high-strength plastic mesh system anchored to the pavement at the end of the runway. The foamed silica is poured into lanes bounded by the mesh and covered with a poured cement layer and treated with a top coat of sealant.
Both EMAS products are located at the end of the runway and are typically the full width of the runway. The length depends on the airport configuration and the aircraft fleet using the airport.
Background
The Runway Safe Group and Safran Aerospace Arresting (formerly Engineered Arresting Systems Corporation, or ESCO), a subsidiary of the Safran Group entered into an agreement for Runway Safe to acquire the ESCO EMAS business. This transaction was completed in February of 2020.
Current FAA Initiatives
The FAA's Office of Airports has made RSA improvements at more than 500 commercial airports. This means that all practicable improvements, including the use of EMAS technology, have been made at approximately 1,000 runway ends at these airports. These RSAs have been improved to full standards or to the extent practicable, not including the relocation of FAA-owned navigational equipment.
EMAS Arrestments
To date, there have been 15 incidents where EMAS systems have safely stopped 15 overrunning aircraft, carrying 406 crew and passengers, aboard those flights.
