-----------------------------------------------------------------------------------------------

TOPIC #3: Aircraft landing performance including landing on contaminated runways, manufacturer's landing data, use of OPCs, and use of thrust reversers

7. Boeing Airplane Company

• Mr. Bob Orlowski (Aero Perf)
• Mr. Paul Giesman (Flight Ops)

Issue areas:

• Airplane Flight Manual landing performance

8. FAA

• Mr. Jerry Ostronic
• Mr. Don Stimson
  AVS Task Force on Safe Landing Distances

Issue areas:

• Task Force purpose, methodology, and progress to date.
• Why is there no minimum safety margin for landing, or how is landing safety margin provided? Certification/regulatory basis? Operational practice?
• Differences in dispatch and landing requirements.
• History of thrust reverser in dispatch calculations and advisory data
• Why do WET conditions give better braking during landing than CLUTTER?
• What factors (e.g., reverse thrust) may be incorporated as an operational landing distance credit?
• How conservative are landing estimates?
• Consistency of stopping distances (different carriers with same models= diff #s?)
• Advisability of putting contaminated runway landing data in AFM.

9. Southwest Airlines
