Presentation Transcript

  1. Runway Safety Areas Mark George Survival Factors Division

  2. Runway Safety Areas • Buffer zone 1000 feet beyond runway ends, and 250 feet on each side of runway centerline 1000feet (longitudinal) 500 feet (lateral)

  3. Runway Safety Areas • Options for improving RSAs: • Acquisition of land (to standards) • Relocate or shift runway • Reduction in runway length • Declared distances • Engineered Materials Arresting System (EMAS)

  4. Runway Safety Areas - EMAS • Engineered Materials Arresting System • Crushable concrete blocks • Attenuates energy as the airplane crushes the blocks • Tunable for “design” airplane and available space • Standard EMAS – 70 knot exit speed • Non-standard EMAS – 40 knot exit speed

  5. Runway Safety Areas - EMAS

  6. RSAs - Chronology of significant events

  7. RSAs - Chronology of significant events

  8. 22L EMAS scheduled completion 10/2007 13C EMAS completed 9/2007 04R EMAS scheduled completion Fall 2007 31C EMAS scheduled completion Fall 2007

  9. Runway Safety Areas • Non-standard EMAS would have stopped the accident airplane • Conclusion: Absence of EMAS contributed to the severity of the accident
