Research on the assessment Method for the safety of Flight Procedure based on Time-space Diagram

In view of the lack of more practical automatic allocation tools for flight interval allocation, this paper proposes a concept of aircraft operation diagram, provides the drawing method of aircraft operation diagram, abstracting the operation time and space position of aircraft, and representing the operation state and future trend of each aircraft on the same diagram. A flight interval increment algorithm is proposed in combination with the operation diagram to evaluate whether the current operation trend meets the requirements of operation safety, realize automatic monitoring and automatic optimization of flight interval deployment, and provide a feasible and practical method for future control monitoring.
