The C919 has the shape of an A320neo but with more modern nose and wingtips.
It is slightly longer than the A320 and has therefore one seat row more in the cabin.
COMAC has sensibly stayed with a fully conventional build-up of the aircraft. It has enough on its plate to learn the ropes of getting a mainline single aisle aircraft through flight testing and certification
The classical build and slightly larger dimension make for a heavier aircraft than A320neo. We check if its more modern wing can bring the performance past the A320neo benchmark.
