This page explains the flight permission and approval procedures required when operating unmanned aircraft weighing 100g or more outdoors. Based on the Civil Aviation Law, permits are necessary for flying in specific airspace (populated areas, airport vicinity, above 150m altitude) or using certain methods (night flight, beyond visual line of sight). Unmanned aircraft are classified into three categories by risk level—Category III, II, and I—with different procedural requirements. Aircraft registration and application via the DIPS2.0 system are mandatory. Operating without proper authorization results in penalties.
