Longitudinal minimum interval of aircrafts based on ADS-B monitoring technique

Abstract

The problem of longitudinal safety interval of aircraft during parallel air route flight is discussed in order to solve the problem of flight safety and improve the accuracy of the collision risk. The traditional EVENT model is improved by using elliptic cylinder as the collision template. The performance and application field of broadcast automatic monitoring (ADS-B) are introduced, and based on the improved EVENT model, a method for calculating the parameters through using ADS-B monitoring technology is put forward. Taking E500 aircraft as a model example, the minimum safety distance is calculated. The results are in line with the international civil aviation organization's flight safety index, which provides an effective method for the study of risk classification based on ADS-B technology.
