Airbus now owns a 50.01% majority stake in C Series Aircraft Limited Partnership, while Bombardier and Investissement Québec own approximately 34% and 16% respectively. CSALP’s head office, primary assembly line and related functions are based in Mirabel, Québec. Airbus’ global reach and scale combine with Bombardier’s state-of-the-art jet aircraft in the C Series, now being produced in a partnership between Airbus and Bombardier. Airbus manufactures, markets, and supports C Series aircraft under the aegis of the Airbus-Bombardier partnership, with Bombardier’s two C Series jetliners being brought into the Airbus commercial aircraft line-up. These airplanes fill an important niche – covering the segment that typically accommodates 100-150 seats – and responding to a worldwide aviation market for smaller single-aisle jetliners estimated at some 6,000 such aircraft over the next 20 years. Series aircraft have been specifically designed for the 100 -150 seat market, resulting in efficiencies inherent in purpose-built aircraft with an unmatched environmental scorecard. What’s more, the CS100 and CS300 have over 99 percent parts commonality between them, as well as the same pilot type rating, facilitating the family’s addition to an airline’s fleet. Up to 5,440 kg lighter than their competitors, C Series jetliners were designed using state-of-the-art computational aerodynamics combined with 21st century supercomputing capability; the result is a family of aircraft with optimal aerodynamic performance and reduced drag. Powering the aircraft are twin Pratt & Whitney PurePower PW1500G geared turbofan engines specifically designed for this jetliner product line. With a bypass ratio of 12:1 – one of the highest of any turbofan engine in the world – the engines feature 20 percent lower fuel burn per seat than previous generation aircraft, half the noise footprint, and decreased emissions. Together, the C Series represents the most efficient aircraft in the skies in their class, with up a low cost per trip, as well as the lowest noise levels of any commercial jet in production. This makes the C Series aircraft ideal for urban operations and noise-sensitive airports C Series aircraft are designed to deliver the feel of a widebody jetliner in a single-aisle aircraft. The cabin provides space where it matters the most, leading to an unparalleled passenger experience. Overhead bins, with the largest stowage capacity in their class, are easily accessible. The windows, extra large and plentiful with more than one at each row, are positioned high on the cabin sidewall to provide an optimal viewing angle and an abundance of natural light. Wide seats –18 inches or more – provide personal space without compromise, and the newly designed engines contribute to the quietest cabin in the C Series’ class.
