Aircraft Deceleration & Kinetic Energy Decay (E_k = ½ m v²)
Deceleration profile combining aerodynamic parasite drag, wheel anti-skid friction braking, reverse thrust, and EMAS crush penetration.
Airport Boundary & Surface Roadway Impact Assessment
When excursions exceed the certified Runway Safety Area (RSA), aircraft penetrate perimeter security fencing and can strike active public roadways, ground support structures, or fuel storage.
Engineered Barrier Mitigation Efficacy
FAA Advisory Circular 150/5220-22B recognizes EMAS as capable of safely arresting transport category aircraft entering up to 70 knots with minimal airframe destruction and no catastrophic breach of adjacent highways. Adding an EMAS bed transforms uncontained high-energy perimeter collisions into survivable contained crush stops.

Evaluation of Runway Design Group (RDG) IV/V dimensions, longitudinal overrun clearance, and frangible navigation aid requirements.
