The Chinese-produced large passenger jet, C919, will make its first long-distance flight on Friday, leaving Shanghai for Northwest China's Shaanxi province where it will undergo further testing.
COMAC has received orders for 730 C919 planes from 27 domestic and international clients.
With a standard range of 4,075 kilometers, the C919 jet is comparable to the updated Airbus 320 and Boeing's new generation 737 planes.
