An Operational Safety Evaluation Method for Manned Transport Aircraft and Large UAV in Mixed Airspace

To improve the predictive ability in trajectory of large unmanned aerial vehicle (UAV) and the calculation performance in complicated circumstances with mixed airspace, multiple aircraft types, and joint operations, the concept of phased trajectory deviation (PTD) is introduced and a corresponding m...
