Implementing the TALPA ARC proposals
Presented by
Lars KORNSTAEDT / Performance Expert, Airbus Flight Operations Support

2. TALPA ARC Concepts Page 2 Airbus Operational Landing Distances
International Air Safety Seminar 2011
TALPA ARC Concepts
Common rules
For all airports
For all manufacturers
For all operators
Shared operational landing performance computation
Realistic Air Distance
Representative Friction
All physical effects considered
Standardized performance to match reported conditions
Standardized runway condition assessment
Allow performance determination for all types of reports

4. Always start assessment with contaminant type and depth

Procedure
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

6. TALPA Rules in a Nutshell
Airbus Operational Landing Distances
International Air Safety Seminar 2011
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

7. Situation for Airbus – BEFORE
Airbus Operational Landing Distances
International Air Safety Seminar 2011
Situation for Airbus – BEFORE
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

8. Airbus Situation – AFTER

International Air Safety Seminar 2011
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

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
