Abstract
The lateral conflict risk assessment of low-altitude training airspace strategic
planning, which is based on the TSE errors has always been a difficult task for
training flight research. In order to effectively evaluate the safety interval and
lateral collision risk in training airspace, in this paper, TSE error performance
using a weakly supervised learning method was modelled. First, the lateral
probability density function of TSE is given by using a multidimensional random
variable covariance matrix, and the risk model of a training flight lateral collision
based on TSE error is established. The lateral conflict risk in specific training
airspace is analyzed, and then the lateral collision model is built. Through the
quantification of the risk probability of lateral collisions, the security level of a
specific airspace is evaluated. The analysis of the examples shows that for normal
training flight in a variety of 4D flight track data, the lateral collision risk in
specific training airspace is 0.543744 × 10
-13, the conflict risk meets the
requirement of safety target level of international civil aviation organization.
