China's indigenously-developed large passenger plane C919 completed its first low-temperature flight test in North China's Inner Mongolia Autonomous Region on Saturday. 

The C919 jet took off from Hulunbuir Dongshan International Airport in the region, and landed at Dongying Shengli Airport in East China's Shandong Province, completing 23 days of tests. 

The low-temperature test is an extreme weather flight test that civil aircraft are required to clear-- aimed at testing the functions and performances of the operational systems and equipment of the aircraft, experts said.

During the flight test, 10 aircraft experiments and four ground experiments related to C919 were verified as meeting standards in a low temperature environment of -35C.

To complete the flight test, Hulunbuir Dongshan International Airport worked with related departments and companies including local airport supply and air control department and China National Aviation Fuel Group Limited (CNAF). Hulunbeier Meteorological Service also placed five sets of meteorological monitor equipment to ensure the precisely climate data during the test. 

C919 jet is China's first independently developed jumbo plane with own intellectual properties, experts said.
