Theory of Operations

Predictable, Reliable Performance for Safely Stopping Aircraft in Overrun Situations!

Zodiac Arresting Systems’ EMAS design involves complex computer analysis of over 100 variables for each operating aircraft. Material strength & depth varies to provide optimum performance.

  • As the aircraft traverses the bed, the wheels crush the EMAS material creating a tire/material interface.
  • It is the point of the tire/material interface that provides the resistive loads to decelerate the aircraft.
  • The loads are placed on the aircraft landing gear and support structure.
  • Level of performance depends primarily on landing gear strength and runway safety area available.
