Understand the Challenges
The key driving factors for the future air transport system have been captured and analysed
MARKET REQUIREMENTS1. High Productivity2. Low cost of operation3. Superior reliability/maintainability4. Comfort / health driven cabin design5. Low cost of acquisition6. High flexibility/updatability7. Family Concept design8. Market specialisation
ENVIRONMENTAL PRESSURE9. Low noise10. Reduced emissions11. Low manufacturing impact
INTEGRATION IN THE SYSTEM12. Solution to airport congestion13. Good airport compatibility14. Exploiting new ATM opportunities

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 :
