3. Benefits of investing in aeronautics technologies
 Environment
 Greener products into service sooner
 Less noise, lower emissions
 Reduced fuel consumption
 Greener design, production and maintenance
 Faster introduction of innovative technologies
 Application across all commercial aircraft
 Socio-economic impact
 Integrating European industry
 Open access to SMEs and New Member States
 Expected multiplier effect via complementary National Programmes
 A competitive European industry leading the introduction of more
environmentally friendly products and sustaining the creation of
highly qualified jobs
 Major contribution to sustainable growth in Europe

Technology Readiness Level

4. Towards a High maturity
A high level of « technology readiness »: the technologies
are integrated into large demonstrators, in-flight or on-
ground
 Demonstrators definition close to the market needs: the
demonstrator is the last R&T phase, before starting a
development
 Schedule is key to keep this link (be neither too early, nor too
late)
 A large part of this downstream research activity lays within
big players, « integrators » - a typical feature of aeronautics
 These activities must be thoroughly coordinated
A large programme focused on environment…
… and compe++veness
These features create the condi0ons for a Public‐
Private Partnership 7
Aerospace Technology 2010, Stockholm,
