Engineered Materials Arresting System

This System uses a specially installed porous surface which quickly stops any aircraft that moves onto it. EMAS may be installed at the end of some runways to reduce the extent, and associated risks, of any over run off the end of the runway compared to the equivalent soft ground distance. As such it may be an alternative to a Runway End Safety Area (RESA) where the topography precludes the full recommended length of a RESA or it may be used in addition to a full length RESA where precipitous terrain immediately follows the end of the RESA. Operationally, it may also be installed to prevent an overrun affecting other runways and therefore increasing the capacity consequences of an overrun.
