  2. Develop Capabilities for Multiple Challenges Past : one single concept to best meet all requirements Past : one single concept to best meet all requirements Past : one single concept to best meet all requirements Today : a family of concepts tailored to fit specific sets of requirements Requirements The idea is to select the concepts to explore the more relevant capabilities and meet the widest range of challenges

  3. Understand the Challenges SYSTEM MARKET ENVIRONMENT The key driving factors for the future air transport system have been captured and analysed MARKET REQUIREMENTS 1. High Productivity 2. Low cost of operation 3. Superior reliability/maintainability 4. Comfort / health driven cabin design 5. Low cost of acquisition 6. High flexibility/updatability 7. Family Concept design 8. Market specialisation ENVIRONMENTAL PRESSURE 9. Low noise 10. Reduced emissions 11. Low manufacturing impact INTEGRATION IN THE SYSTEM 12. Solution to airport congestion 13. Good airport compatibility 14. Exploiting new ATM opportunities

  4. Select the Champions From the foreseen range of requirements, Airbus has selected typical concepts, as most able to drive the innovations in their respective field of difficulty : The Simple Flying Bus The Proactive Green The Payload Driven The Value of Speed The Flying Truck Irrespective of final future product configurations, the champions will act as basic vectors, describing the whole set of future capability development

  5. Extend the Capability Limits System Market Environment Development of the Champion Concepts will extend the capability limits beyond the natural trend of the classic configuration, as shown in the following assessment Classic Configuration (ref.) Simple Flying Bus Proactive Green Payload Driven Value of Speed 1 Value of Speed 2 Flying Truck Classic configuration used as reference (red line)

  10. Requirements for High Lift Devices Clmax limit Vapproach = 1.23 x Vs1g + 5 kts CLapproach = f(CLmax) Vapproach = 1.23 x Vs1g + 15 (20) kts cruise • Provide sufficient lift to meet Vapp • Avoid tail-strike @ touch down • Avoid NLG first impact @ touchdown for High speed landing Max Alpha cases CL Overspeed cases CL0 NLG First Impact Tailstrike Alpha

  11. Typical Airbus • Description • High lift: Slats, single slotted fowler flaps & aileron • Roll control: o/b aileron & spoilers • Load control: o/b aileron & spoilers • Lift reduction: spoilers • Speed brake: spoilers
