Acknowledging that airlines are concerned about more than bottom-line operating costs when it comes to choosing airplanes, Bombardier unveiled the airplane’s cabin mockup here at Le Bourget to claim best-in-class passenger comfort for its proposed C Series of single-aisle airliners.

Counting the Boeing 737-600/700, Airbus A318/319 and Embraer 190/195 as potential competitors for the still-to-be-launched C Series, the Canadian airframe maker said its new Pratt & Whitney Canada-powered airliner would boast the widest seats (18.5 inches in five-abreast configuration) and widest aisle (20 inches).

The C Series would be offered in two versions, the C110 (110 to 115 seats) and the larger C130 (as many as 130 seats). A short-range version would fly 1,800 nm, while planned transcontinental variants would fly 3,000 nm, Bombardier said. Goals for the program are a 15-percent cash operating advantage over competing aircraft, 99-percent reliability from the first day of operation and “passenger appeal” in the form of bigger seats and windows and more baggage space.
