Aeronautical Safety Engineering References & FAA Criteria

FAA Advisory Circular 150/5300-13B (Airport Design): Standard Runway Safety Areas (RSA) for Design Aircraft Group IV/V (e.g., Boeing 767/777) require a 500-foot total width and 1,000-foot overrun containment length beyond the physical runway end. Paved terrain must be cleared, drained, graded, and free of hazardous surface variations.

Perimeter Hazard Mitigation: When physical constraints (canals, perimeter service roads, public thoroughfares, rail spurs, or drainage swales) lie within or immediately adjacent to the overrun zone, AC 150/5220-22B approves Engineered Material Arresting Systems (EMAS). Cellular concrete crush blocks safely dissipate aircraft kinetic energy through controlled landing gear drag, arresting aircraft at entry speeds exceeding 70 kt without catastrophic structural breakup.

It does not replace aircraft flight manuals (AFM/QRH) or active NTSB accident investigation findings.
