More Commonality. Better Integration.



Airbus’ commonality philosophy ensures harmonisation across Airbus products, optimising pilot and maintenance training costs across the board.



The A350 Family’s high degree of spares and tooling commonality coupled with Airbus’ Flight Hour Services component management solution helps operators simplify and lower their operating costs.



The Trent XWB engine has been designed to reduce costs and increase efficiency through commonality, across spares, tooling, training and maintenance procedures.




From the A320 to the A350, all Airbus aircraft have been developed following the same fly-by-wire philosophy and similar flight deck layouts.


A330 A350 Cockpit Commonality
Flight deck commonality benefits
  • Shorter trainings for pilots between different aircraft types
  • Pilots can hold more than one type qualification
  • Reduced number of flight crews
  • Higher flight crew productivity          

This cockpit commonality allows pilots to move from one aircraft type to another within short training periods and to handle more than one type qualification to fly different aircraft types at the same time.


A350 commonality Pilot Training vs other Airbus aircraft programme

One of the great commonality examples within the Airbus widebody family is with regards the A330 and the A350 cockpit commonality. 

Airbus has been granted regulatory approval of a Common Type Rating (CTR, difference training course) for A330 and A350, based on handling similarities.

A330 pilots are expected to qualify on the A350 in 8 working days without mandated Full Flight Simulator time.

Using the same principle, the A350 pilots can benefit from a reduced Type Rating to be also qualified on A330.





The commonality philosophy between the A350-900 and A350-1000 also trickles down to the aircraft systems. 

This high degree of spares and tooling commonality within the A350 Family reduces the associated investment costs when both aircraft types are operated together.

A350 Family Spares Tools Commonality

When it comes to maintenance training between different aircraft families (A330 to A350 for example), operators can have their mechanics undergo Cross Mechanic Qualifications, which is essentially a shortened licensed B1/B2 mechanics training between certain aircraft types.

This advantage translates into having a reduction in the number of mechanics by economies of scale and increasing mechanic productivity.

Flight Hour Services (FHS)

FHS Components is the best solution to further streamline the management of your spare parts, while optimising your costs and transforming your upfront investment from CAPEX into OPEX.


Flight Hour Services (FHS) Savings

FHS Components offers guaranteed availability of all primary Line Replaceable Units (LRUs) spare parts, to keep your aircraft flying. It also provides you with exclusive inventory at your main base and selected outstations, backed up by unlimited pool access to deliver a guaranteed service level. In addition, through accurate reliability monitoring, we track and improve your components‘ performance.





The A350 Family’s commonality reduces maintenance costs not only through simplification of system architectures, maintenance procedures and reductions in spare holdings but also by having the leanest maintenance programme.


The Trent XWB engine has been designed specifically for the A350 and it benefits from an optimised performance and commonality across its two thrust versions, the Trent XWB-84 and the Trent XWB-97. 

Optimised commonality contributes to reducing costs and increasing efficiency across LRUs and IP, tooling, training and maintenance procedures, enabling an airline to operate both Airbus A350-900 & A350-1000 within their fleet with maximum efficiency and operability.



A350 family Engine Commonality Savings

80% spares commonality and 1.8 million dollars potential savings

A350 | More commonality. Better integration.

When considering the A350, the question of integration into your current fleet will be paramount. Commonality across the cockpit, systems and engine reduces your upfront investment, training costs and generally simplifies operations.This integration is made even smoother when opting for FHS components to streamline spare parts management.  

Using the same Airbus philosophy the A350 cabin has also been designed with commonality in mind. The award-winning Airspace cabin ensures a consistent premium passenger experience across your fleet and gives operators even more revenue generating capabilities.
