1 1 Los Angeles World Airports | LAX Interim Runway Safety Improvement Project Update of Interim Safety Improvement Planning Presentation to Board of Airport Commissioners November 16, 2009 Michael D. Feldman Deputy Executive Director Facilities Management Group

2 2 Los Angeles World Airports | LAX Interim Runway Safety Improvement Project LAWA’s Airfield Safety Goals Overall: Continue to be proactive in enhancing safety on the airfield while maintaining efficient movement of aircraft Interim: Reduce risk levels as much as possible while maintaining airfield operational efficiency pending ultimate North Airfield configuration decisions Long-Term Improvements: Eliminate and/or substantially reduce levels of risk while maintaining airfield operational efficiency

3 3 Los Angeles World Airports | LAX Interim Runway Safety Improvement Project Background of IRSIP Study North Airfield Technical Studies – Independent Airfield Safety Assessments 2007 North Airfield Safety Risk Assessment Report Independent North Airfield Safety Study (NASA, Academic Panel) - ongoing BOAC Direction to LAWA to Identify Further Safety Enhancements During Interim Period IRSIP Study Status Update Presentation to BOAC on April 6, 2009

4 4 Los Angeles World Airports | LAX Interim Runway Safety Improvement Project Airfield Safety Improvements Implemented South Airfield Improvement Project - completed Enhanced Marking and Lighting System – completed Runway Status Light System – pilot program completed ASDE-X system installation – completed Pilot and Controller Awareness Program – on-going

5 5 Los Angeles World Airports | LAX Interim Runway Safety Improvement Project Safety/Risk Terminology Hazard: condition that is necessary to lead to an incident or accident. Likelihood: Probable frequency of hazard occurrence (i.e. once per week/month/year/10 years/100 years). Severity: A measure of the end result (i.e. increased pilot and FAA workload, extreme pilot measures to avoid collision, loss of life and property). Risk: a predicted result of an event and the probability of the event occurring.

6 6 Los Angeles World Airports | LAX Interim Runway Safety Improvement Project FAA Engineering Recommendations FAA places priority on runway separation and proper airfield geometry Pending resolution of the final airfield geometry, the FAA prefers the following: “.... The preference is for aircraft to cross in the last third of the runway whenever possible, since within the middle third of the runway the arriving/ departing aircraft is usually on the ground and traveling at a high rate of speed.” 1/ 1/ FAA Engineering Brief No. 75: Incorporation of Runway Incursion Prevention into Taxiway and Apron Design, November 19, 2007.

13 13 Los Angeles World Airports | LAX Interim Runway Safety Improvement Project Next Steps December Board Meeting: Staff will request authority to initiate IRSIP design and environmental review Provide results of this work to NORSAC Committee and the Academic Panel. On-going collaboration with the FAA regarding additional Runway Status Light Installations and IRSIP Finalize Safety Risk Management Panel Report

14 14 Los Angeles World Airports | LAX Interim Runway Safety Improvement Project Discussions/Questions

15 15 Los Angeles World Airports | LAX Interim Runway Safety Improvement Project North Airfield Hazards Hazard LAX001 – Taxiway Y What is going on: Simultaneous use of Runway 24R for Arrivals and Runway 24L for Non-Heavy Departures What may occur: The departing Non-Heavy aircraft is cleared for departure and begins its takeoff roll and the arrival on Runway 24L, instructed to hold on Taxiway Y, approaches to hold line at the same time. What is the hazard: The aircraft that landed on Runway 24R inadvertently crosses past the hold line on Taxiway Y and crosses Runway 24L at the same time a Non-Heavy begins its departure roll down Runway 24L. What may be the outcome if the hazard occurs: Either or both pilots conduct a severe maneuver to avoid a potential collision, which would be classified by the FAA as a “severe operational error.”

17 17 Los Angeles World Airports | LAX Interim Runway Safety Improvement Project North Airfield Hazards Hazard LAX001 – Taxiway Z What is going on: Simultaneous use of Runway 24R for Arrivals and Runway 24L for Non-Heavy Departures What may occur: The departing Non-Heavy aircraft is cleared for departure and begins its takeoff roll and the arrival on Runway 24L, instructed to hold on Taxiway Z, approaches to hold line at the same time. What is the hazard: The aircraft that landed on Runway 24R inadvertently crosses past the hold line on Taxiway Z and crosses Runway 24L at the same time a Non-Heavy begins its departure roll down Runway 24L. What may be the outcome if the hazard occurs: Either or both pilots conduct a severe maneuver to avoid a potential collision, which would be classified by the FAA as a “severe operational error.”
