The Bombardier CSeries aircraft contains a high usage of composite materials and larger windows. The CSeries cabin features large, rotating overhead storage bins, allowing each passenger to stow a sizeable carry-on bag overhead. Compared to the cabins of current in-service narrowbody aircraft, the CSeries is to provide airlines with the highest overhead bin volume per passenger and a wider aisle that would allow for faster boarding and disembarkation of passengers.
The CSeries aircraft contain 70% advanced materials comprising 46% composite materials and 24% aluminium-lithium which allows for a 15% lower seat-mile cost and a significant reduction in maintenance costs. Computer software design tools were used on the project, including CATIA, HyperSizer, and similar technology that was employed in the Learjet 85 programme.
