Two Chinese manufactured C919 planes and three ARJ21 aircraft made their official debut at the Singapore Airshow on Tuesday, according to press release sent to the Global Times.
During the event, the planes will perform flight demonstrations, conduct in-hall model exhibitions and outdoor displays, through which China is about to present to the public the phased results its commercial aircraft project has achieved, said the statement.
On the sideline of the Singapore Airshow, China's Tibet Airlines and COMAC signed a contract for 40 high-altitude C919 plane orders and 10 ARJ 21 orders. Henan Civil Aviation Development & Investment Co also ordered six ARJ 21 planes including fire-fighting aircraft, medical use aircraft and emergency rescue aircraft, COMAC said in a separate statement sent to the Global Times.
The C919 high-altitude variant is a significant development of the orginal C919 model, which meets the transportation requirements in plateau areas by shortening the fuselage and other plateau-use modifications, with 140 to 160 seats.
The maximum takeoff and landing altitude of the ARJ21 plateau model is 14,500 feet （4,419.6 meters）, with a good takeoff and landing performance at high plateau airports with crosswind resistance ability, which can be used at most of the high plateau airports in China.
China's homegrown passenger jets have become one of the highlights at the event since it is the first time China flies its homegrown plane before international aviation enthusiasts overseas.
