What is the function of an Engineered Material Arresting System (EMAS)?

The function of an Engineered Material Arresting System (EMAS) is specifically designed to absorb energy during aircraft overruns. This system consists of a specially designed material that compresses upon impact, effectively slowing down an aircraft that has inadvertently exceeded the runway length during landing. By doing so, the EMAS can help prevent potential damage to the aircraft and minimize the risk of incidents on the runway.

While facilitating aircraft landings, assisting in takeoff, or serving as taxiway barriers are important aspects of airport operations, they do not accurately describe the primary role of an EMAS. The design and function of EMAS systems are focused solely on enhancing safety during runway overruns, making them a critical safety feature in aviation infrastructure.
