Despite any disturbancies aviation industry is still expecting 4.8% global annual growth in terms of growing passenger movements

Short range transport will increase in growing countries with own manufacturing industry Long range transport will grow between „Western World, Middle East and Growing Countries

Mobility nearly independent from economic growth and static

Mobility steep increasing function of the economic growth

- Middle East reaches 2/3 of global population within 8 hours flight

- 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

Asian crisis

- 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

Trade Off between Mobility and Green Transportation

- Balance of time, cost, emissions, effort - 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)

The Paradigm Shift of Flying Qualitative Growth of Aviation

Airbus

- Common Vision - Joint targets and common goals

- Integrated ATS

- Understanding of systems dependencies

2040: DLR BWB - It offers potential benefits - Expand the design space and possibilities - It gives answers to global developments - „Known unconventional“! - It is emotional! - Still technically challenging
