Abstract

The invention relates to a method for acquiring the airplane vertical occupancy rate. The method comprises the following steps: the acquired flight flow sample data is processed to obtain the data information of all flights; the position information of each way point of the flights on the flight line and the flight information of the flights to pass through each way point are extracted from the data information of each flight; two flights are compared in sequence according to the position information of the way point and the flight information of the flights to pass through each way point to determine the number of the flight pair with collision risk; and the vertical occupancy rate is determined according to the number of the flight pair with collision risk. The flight pair with collision risk does not depend on the individual empiric parameter value, and not adopt the direct statistical method for the complex parameter. Therefore, not only the accuracy of the calculated vertical occupancy rate is high, but also the use is simple and convenient, and the invention is convenient for engineering realization, is favorable for the quantitative description of busyness of the aerial traffic to realize, provides the accurate data basis for the airspace running analysis and the safety assessment, and has wide application prospect.

Description

technical field [0001] The invention relates to an acquisition method of airspace operation analysis and safety assessment data, in particular to an acquisition method of aircraft vertical occupancy rate. Background technique [0002] With the rapid development of the air transport industry, the air traffic continues to grow, and the existing airspace capacity is becoming saturated, which greatly restricts the sustainable development of the air transport industry. To this end, the international civil aviation industry is actively developing and applying advanced aviation communication, navigation, and surveillance technologies to gradually reduce the horizontal and vertical separation standards between aircraft, which greatly improves the utilization of airspace. However, the reduction of the separation standard between aircraft will inevitably lead to an increase in the risk of collision, which will affect the safety of air transportation. The International Civil Aviation ...
