Airbus Operational Landing Distances FAA TALPA ARC – Runway Assessment Matrix Reporting Code Measured Friction Reported Braking Action DOWNGRADE ONLY Primary Assessment Differentiation by Temperature PiRep Guidelines
Always start assessment with contaminant type and depth • Use additional information to • Degrade to lower friction code • Never upgrade • Careful with friction reports • May be optimistic on fluid contaminants • Do not hesitate to request additional information from ATC Airbus Operational Landing Distances Procedure

Airbus Operational Landing Distances TALPA Rules in a Nutshell • Provide Runway Status Reports • Using Matrix and associated methodology • In a performance oriented way • Publish Realistic Landing Performance Data • In accordance with agreed rules • For all supported aircraft types • Make Systematic Landing Performance Check • In all cases except for dry runway • Apply a 15% margin to the result
Publication for in-flight use • Unfactored certified reference distances used for dispatch • For incomplete list of contaminant types and depths • Coverage of loose snow by equivalence only • Inconsistent assumptions between dry/wet and contaminants for airborne phase • Operators must define their own margins • Pilots have difficulty in using published data with diverse runway condition reporting methods Airbus Operational Landing Distances Situation for Airbus – BEFORE
Airbus Operational Landing Distances Airbus Situation – AFTER • For all Airbus aircraft • At least “Minimum Compliance” with TALPA ARC • Cover all 6 friction levels • Accountability for • Temperature effect • Runway slope effect • Matrix as entry-point • All Performance data sources • Flight Ops Engineer Software • Flight Manual • Operational Documentation • Electronic Flight Bag • Training Material

Airbus Operational Landing Distances Conclusion • Airbus adopts TALPA ARC standard for in-flight landing performance including for non-normal and in ROPS • Realistic computation basis for all winter runway conditions • In current environment, pilot must compensate for non yet compliant Runway Condition Reporting • Major safety step change requires SHARED Global Assessment & Reporting STANDARDS
