英文摘要：

Air Performance-Based Navigation （PBN） freeways in the next generation aviation transportation system （NGATS） are characterized by monolayer route with single direction, no crossover, aircraft performance limitation, and high density of operation. In order to study the traffic flow operation on the air PBN freeways, introducing basic functions of flights traffic flow, density and velocity, along with relationship equation. A dynamics model of aircraft flow for single layer route Of air PBN freeways was established using the dynamics theory of traffic flow, based on the civil aviation operation rules of NGATS. Through analysis of the aircraft flow relationship between velocity and density, a stable equilibrium state model of aircraft flow for air IPBN freeways was then deduced. The model can be used for air route flow optimization and capacity valuation. With the model, aircraft flow was studied in the terminal area. The calculation capacity is in agreement with actual situation. The model shows method of reduce-aircraft-wake-interval can improve PBN route flow.
