KUNMING, Nov. 21 (Xinhua) -- China's civil AC312E helicopter, which made its maiden flight in July 2016, on Tuesday completed all plateau test flights, according to its developer, the Aviation Industry Corporation of China (AVIC).
AC312E, a light twin-engine civilian helicopter, completed plateau testing at Ninglang Luguhu Airport, a commercial airport at an altitude of 3,293 meters in southwest China's Yunnan Province.
Installed with Arriel 2H heli-engines, the AC312E has now completed all requirements for high-altitude helicopters, according to AVIC Hafei.
"AC312E has shown reliability and good performance on all types of plateau environments. It can now meet demand for emergency rescue and earthquake relief helicopters in plateau regions," said Li Shengwei, deputy chief designer of the AC312E.
The maximum take-off weight of the AC312E is 4.25 tonnes, with a maximum payload of 1.7 tonnes. It can carry nine passengers.
