Boundaries for Future Developments Changing Global Air Traffic Flow - Middle East reaches 2/3 of global population within 8 hours flight
8 hrs 4 hrs
- Mega airport turntables provide significant long range transport capacities - Air transport flows will change resulting in a changing relevance of the acutal airport hubs and spokes in Europe - European Airlines will benefit but also change their business models due to the Middle East and Asian developments

Trade Off between Mobility and Green Transportation - Mobility is a major pillar of high life style and prosperity - Increasing energy/oil cost and ecological responsibility argue against quantitative traffic growth - Ensure mobility with less energy effort, materials, emissions and noise requests for less traffic less aircraft, less airport, airspace capacity - Passenger mobility can be achieved with less aircraft movements - Cost and emissions per flight are to be shared by more people per trip
Paradigm shift from quantitative air transport growth to qualitative air transport growth

The Paradigm Shift of Flying Qualitative Growth of Aviation - Balance of time, cost, emissions, effort Airbus - Less traffic, less aircraft, consolidated capacities - Less noise and emissions - More potential for robustness, and reliability in the transportation processes - Increased level of service - More comfort and relaxed travel experience - Air transport is more attractive - More potential for punctuality (door to door) Airbus
- Common Vision - Joint targets and common goals - Integrated ATS - Understanding of systems dependencies Source: U. Becker, TU Dresden, V. Gollnick, DLR
