Research on Controlled Flight Into Terrain Risk Analysis Based on Bow-tie Model and WQAR Data

Abstract

Controlled flight into the terrain (CFIT) is the main types of civil aircraft accidents. In this paper, we bulid the risk model for CFIT event, which is based on Bow-tie analysis model. At the same time, we calculated and verified this model by using China civil aviation flight quality monitoring station’s A320 fleets of flight data, and analyzed the results based on the time dimension and China's domestic airport dimension, finally achieved the warning function of CFIT event risk.
