If an plane is always to overrun a runway, utilizing EMAS (Engineered materials arresting programs) permits the aircraft to sink into a light-weight content, which can assistance the aircraft swiftly decelerate.
The 'arrestor mattress,' made of crushable components, will crush under the aircraft's fat, slowing the airplane all the way down to a complete cease. The arrestor mattress can assist gradual or end the aircraft, irrespective of whether the EMAS region is up to one,000 feet extensive, dependant upon Each individual situation.
Experiments had been carried out to assist style and design the technique, and initial tests had been done on phenolic foam and mobile cement with the FAA Boeing 727. In 1994, the FAA and JFK Airport formulated and put in one of many prototype arrestor beds on runway 04R.

An EMAS is comparable in strategy on the runaway truck ramp or race circuit gravel lure, made from gravel or sand. It is meant to prevent an plane which has overshot a runway when there Emas is inadequate free of charge Place for a typical runway safety region (RSA). Several patents happen to be issued on the construction and structure within the elements and method.
