The C919, China’s large homegrown passenger jet, has finished its first high-speed taxiing test, coming one step closer to its maiden flight. Most ground-based pre-flight evaluations have been completed. The C919 is a single-aisle,168-seat, twin-engine jet for medium-haul flights, designed to compete with the updated Airbus 320 and the new-generation Boeing 737, which currently dominate the market. As of last November, COMAC had received 570 orders for the C919 from more than 20 customers.
