By GlobalData"The geared turbofan (GTF) engine has over 10,000 hours of ground and flight testing and we’re confident that it will enter into service meeting or exceeding the fuel burn, emissions, thrust and noise specifications, as promised by Pratt & Whitney."
The flight test programme comprises four CSeries FTVs, which have accumulated a total of around 330 flight test hours as of June 2014.
Designed for the 100 to 149-seat, single-aisle market, the CSeries aircraft is claimed to offer a 15% operating cost advantage, a 20% fuel burn advantage.
