An Engineered Materials Arresting System (EMAS) is an installed surface placed beyond the end of a runway, and designed to safely stop an overrunning aircraft. The EMAS bed is designed to stop an aircraft by exerting smooth deceleration forces on its landing gear as the aircraft enters the bed and the EMAS material deforms. The EMAS bed design minimizes the potential for structural damage to aircraft.
This Briefing Leaflet covers what EMAS is, how to identify it and provides general advice on engaging an EMAS.
Before take off and landing, pilots should be aware of the presence of an EMAS bed.
