New data suggests the Comac C919 narrowbody airliner may not have achieved the low weight expected of a new advanced design.
AviationWeek reports preliminary C919 specifications issued suggest it is unexpectedly heavy for a new-generation airliner. Gross takeoff mass for the extended-range version will be 77.3 tons (170,400 pounds), almost the same as that of the 1980s-technology Airbus A320 while carrying only six more passengers over the same range of 3,000 nautical miles.
Comac is promising a 10% reduction in direct operating costs but there seems a hesitation on the part of the state airlines to seriously commit to the C919.
