Comprehensive Study on Assessment Model of Free Flight Collision Risk

Abstract

The free flight concept and the research status at home and abroad were summarized. Then the collision risk model of the Reich model, the double ice hockey model, the event tree model, the stochastic analysis model, have analyzed, and then the application scope, merits and drawbacks of each model were analyzed. Furthermore the collision risk assessment model of free flight based on CNS performance was studied. This provides a theoretical basis for the further research of free flight in the future.
