 China's first civil aircraft with its own intellectual property rights, the C919, started its high temperature operating test on Sunday and landed at Turpan Jiaohe Airport in Northwest China's Xinjiang Uygur Autonomous Region.

According to media reports, an extreme weather test is compulsory for all planes still in the research and development stage in China and abroad. The C919, as a domestically produced large passenger plane, has to go through trials such as the high temperature test. 

The testing environment at Turpan Jiaohe Airport can reach 42 degrees Celsius and 70 degrees on the ground. Turpan is one of the hottest places in China in the summer, thus it offers the best environment for high temperature aircraft testing. 

The C919 aircraft will also undergo its flying tests there.

The C919 is a narrow-body jet developed by Chinese aerospace manufacturer the Commercial Aircraft Corporation of China (COMAC). Its development was launched in 2008 and production of a prototype began in December 2011.
