Abstract

In order to reduce the risk of collision between aircraft and improve the efficiency of airspace resource utilization, this paper proposes an improved EVENT model. The improved EVENT model is based on the rectangular collision template, which is a combination of a cylinder and two cones, so that the improved collision template is more consistent with the real form of the aircraft. Meanwhile, based on the traditional EVENT model, the collision risk model is established in the same height longitudinal plane, the same height lateral plane and vertical plane, and the calculation method of collision risk in different directions is proposed. Finally, taking the Airbus A380 model as an example, the relevant parameters are brought into the Excel table for calculation, and then the magnitude of the collision risk of the improved EVENT model is compared with the collision risk of the traditional EVENT model and the collision risk of the safety target under the ICAO standard. The results show that the collision risk calculated by the improved EVENT model is 9.0% higher than that calculated by the traditional EVENT model, and all of them meet the collision risk requirements of ICAO, so the model can be used to evaluate the aircraft collision risk, and the calculation results are more accurate.
