• « FAILURE CONDITION »
DEFINITION FROM CS 25 1309
• A « Failure Condition » is defined at each system level by its effects on the
functioning of the system. It is characterised by its effects on the other
systems and on the aircraft.
All single failures or combination of failures including failures of other
systems that have the same effect on the considered system are grouped
together in the same « Failure Condition »

INTEGRATION
The worldwide leader in air and space platforms and systems
Become the worldwide leader in air and space platforms and systems (mainly platform-related
systems architecture and integration) with a complete portfolio of products, both commercial
and governmental (commercial aircraft, military transport, mission aircraft, helicopters,
fighters, UAVs, missiles, launchers, satellites, systems and secure networks).
Profitability
Achieve best-in-class operational and financial efficiency to reach 10% EBIT in the first half of
the decade 2010-2020.
Focus on core and optimize financial means
Focus on core. This means a new business model approach and the reallocation of
human/financial resources which are currently locked in non-core legacy activities.
Divestments in non-core areas have to be implemented.
Balanced revenues
Achieve around €80bn turnover by 2020 and reach a 50/50 balance in Airbus / other
Divisions' revenues.
Mission-critical service provider to our customers
Achieve a 25% services share – against 10% – of business by 2020 (hence €20bn), focusing
on high-value services initially related to platforms, requiring and developing both customer
intimacy and product intimacy.
Globalisation
Become a true global industrial company with 40% of EADS sourcing and 20% of EADS
employees outside of Europe. Achieve $10bn revenues in North America in non-Airbus
businesses and gain a prime position with US Government.
Moving towards an eco-efficient enterprise
Move towards an eco-efficient company. Environmental issues are to become a transversal
driver towards sustainable development. Airbus' ambitious targets are already defined. To be
done for non-Airbus Divisions.
