The FAA describes the alpha of EMAS, its capability and what it is fabricated out of:
“The FAA began administering analysis in the 1990s to actuate how to advance assurance at airports area the abounding 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 cautiously arrest overrunning aircraft. EMAS uses crushable actual placed at the end of a aerodrome to stop an aircraft that overruns the runway. The tires of the aircraft bore into the failing actual and the aircraft is decelerated as it rolls through the material.
The EMAS technology improves assurance allowances in cases area acreage is not available, or not accessible to accept the accustomed 1,000-foot overrun. A accustomed EMAS accession can stop an aircraft from overrunning the aerodrome at about 80 afar per hour. An EMAS arrestor bed can be installed to advice apathetic or stop an aircraft that overruns the runway, alike if beneath than a accustomed RSA breadth is available.”
“As of October 2014, there are two manufacturers of EMAS articles that accommodated the FAA requirements…EMASMAX is the latest, best abiding adaptation of ESCO’s EMAS, developed with and technically accustomed by the FAA. EMASMAX arrestor beds are composed of blocks of lightweight, crushable cellular adhesive actual advised to cautiously stop airplanes that overshoot runways.
Runway Safe EMAS is a foamed silica bed which is fabricated from recycled bottle and is independent aural a high-strength artificial cobweb arrangement anchored to the pavement at the end of the runway. The foamed silica is caked into lanes belted by the cobweb and covered with a caked adhesive band and advised with a top covering of sealant. Both EMAS articles are amid at the end of the aerodrome and are about the abounding amplitude of the runway. The breadth depends on the airport agreement and the aircraft agile application the airport.”
As of February of 2016, ESCO’s EMAS, the best abounding of the two suppliers, has been installed on over 103 aerodrome ends at 61 airports in the US, according to the FAA. Those installations accept adored at atomic ten aircraft abounding with a absolute of 245 souls, as apparent in the FAA blueprint below.
LaGuardia was a accomplished applicant for EMAS and has had some of its runways able with the arrangement back the 2005, one of which Pence’s 737 fabricated use of Thursday evening. Extensions were fabricated to the airport’s water-side aerodrome thresholds in aboriginal 2015 and they too affection EMAS systems now.
Other new technologies, like Airbus’s Aerodrome Beat Prevention Arrangement (ROTS), accept the abeyant to acutely abate aerodrome overruns in the future. ROTS offers added situational acquaintance and automation for pilots during landing, and is bactericide in nature. Such a system, forth with added EMAS installations at airports with abbreviate runways and baby beat areas, could massively abate the regularity of these types of incidents, and the severity of their appulse back they do occur.
