Avicopter AC-311
The Avicopter AC311 is a Chinese light utility helicopter developed from the Harbin Z-11 family. It is intended for training, police, medical, and private-transport missions and uses a modern glass cockpit. The design illustrates China’s effort to build a domestic civil-helicopter industry instead of relying entirely on licensed foreign models. Production has remained small, making it an unusual sight outside China despite its conventional light-helicopter layout.

The AC311 is China's homegrown answer to Western light helicopters, developed from the Harbin Z-11 rather than a foreign licence.
