The Chinese-developed AC312E light civilian
helicopter has passed its stability flight test, a key performance test for helicopters.
The model has undertaken multiple flight
tests totalling 18 hours, including those for stability and cooling of its
propulsion system, at a civil airport in Jiamusi, northeast China's
Heilongjiang Province.
It represents a major step for AC312E on
its validation flight test journey as a new helicopter model, the AVIC said.
