According to the Civil Aviation Administration of China, in order to better guide and standardize the type certification process for Normal-class powered lift unmanned aircraft systems (unmanned) and Normal-class multi-rotor unmanned aircraft systems (unmanned), and drawing on practical experience from multiple type certification projects, our agency has organized the drafting of the Advisory Circulars "Airworthiness Standards for Normal-Class Powered Lift Unmanned Aircraft Systems (Unmanned) (Draft for Comment)" and "Airworthiness Standards for Normal-Class Multirotor Unmanned Aircraft Systems (Unmanned) (Draft for Comment)," and is now soliciting public comments.
