  1. Comparing Runway Excursion Factors  Scott R. Winter, Steven M. Leib, Robert C. Geske, Tyler B. Spence, Lauren A. Sperlak, Lukas Rudari, Craig D. Cestari Flight Safety Foundation Student Chapter at Purdue University October 30th, 2013 Flight Safety Foundation 66th International Air Safety Summit Washington, D.C. Special thanks to Founding Chapter Advisor: Stewart Schreckengast

  2. Student Chapter • Inaugural chapter at Purdue University • Research based student organization, consisting of both undergraduate and graduate students • Currently comprised of 11 active members

  3. Introduction & Purpose Review of factors of runway excursions 1 Comparison of reports 2 Analysis of FSF dataset for landing excursions 3

  4. Comparing Reports Boeing Report FSF Report • Reports are independent • Most causal factors contributing to runway excursions are similar

  5. Comparing Reports

  6. Database Exploration

  7. Type of Operator Factors remained fairly constant across the Type of Operator • Contaminated runway • Unstable Approach • Landing long

  8. Type of Operator Contaminated Runway Reverse Thrust Malfun. Unstable Apph

  9. Risk Factor by Aircraft Type Aircraft type does not appear to play a role

  10. Aircraft Class Top 3 factors for business jets, commercial jets and turboprops:

  11. Aircraft Class Excursion Factors of Aircraft Class by Percentage

  12. Stabilized Approaches Why do excursions happen after stabilized approaches? 183 out of 520 landing excursions from FSF Database (1995-2010) we classified as stable approaches (50 were unknown)

  13. Stabilized Approaches

  14. Pilot Factors – Stabilized Approaches

  15. Conclusions Excursion factors appear to be fairly consistent across conditions 1 • Most commonly cited factors were: • Runway contamination • Landing long/fast • Landing after unstabilized approach 2 Even after a stabilized approach, safe landing is not guaranteed 3

  16. The End Questions?
