Approach of UAS airspace integration based on systematic classification and level of safety assessment

UAS (Unmanned Aircraft System) airspace integration, which means UAVs entering non-segregated airspace, is the trend of next generation air transportation system, which will also bring new challenges to the air traffic management. Referring to the airspace integration project of United States, the classification of airspace should be proposed. Based on the comprehensive capacity of the UAS, the operations profile can lead to a full dynamic operation solution. Aiming at evaluating UAS, two aspects are taken into consideration: the classification of the systems and the assessment of safety level; in which the two key factors of system classification are autonomous controllability and surveillance method. The airspace integration of a certain type of UAS can be achieved by define the accessible airspace and the mode of operating through different types of airspace.
