Computing Model of Airspace Utilization Rate Based on Airspace Load

A model for the computation of the airspace utilization rate is put forward to help the airspace manager assess the airspace usage effectively. Through proposing the concept of “airspace load”, the airspace resource is quantified and a new definition of the airspace utilization rate is introduced. Based on the new definition and the research about airspace capacity and air traffic flow management, a model is established by analyzing the flying process of an en-route to compute the utilization rate of the en-route. To know the computation feasibility and ability of the model, it is applied to a given en-route in the computational example, the results of which show that the model can simulate the operation process of the en-route and can reflect its usage situation.
