2 © AIRBUS S.A.S. All rights reserved. Confidential and proprietary document. Develop Capabilities for Multiple Challenges The idea is to select the concepts to explore the more relevant capabilities and meet the widest range of 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

Understand the Challenges 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 ENVIRONMENT MARKET SYSTEM

Irrespective of final future product configurations, the champions will act as basic vectors, describing the whole set of future capability development 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

Extend the Capability Limits 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 SystemMarket Environment Classic configuration used as reference (red line)
