The full-scale CR929 mock-up unveiled at this month's Airshow China by Russian-Chinese venture CRAIC illustrates how the cockpit and cabin of the widebody might look.
The revealing at Zhuhai was the first time that partners United Aircraft of Russia and China's Comac have displayed a physical mock-up of the twinjet.
The two-crew flightdeck has a similar arrangement to the Comac C919 single-aisle, incorporating a five-screen EFIS display set-up and sidestick controls.
The cabin section illustrates possible premium- and economy-seating arrangements. The business cabin has a four-abreast arrangement while the economy area shows a nine-abreast layout.
The baseline CR929-600 will seat 280 passengers in a standard three-class configuration and offer a range of 6,490nm (12,000km). A shorter -500 variant is proposed, seating 250 passengers with a range of 7,570nm while the planned 320-seat -700 stretch would have a range of 5,400nm.
