“…Hsu researched the aircraft collision risk problem of intersecting air-routes for aircraft pairs flying on level air-routes at the same altitude with the invariable speed and both the Gaussian and the double double exponential model are used for the position error distributions to compute the aircraft overlap probability [8] . A Post-Reich' event model was developed by Brooker for lateral collision risk in air traffic track systems and applied to lateral collision in the North Atlantic Region track system, which resolves the problems of the Reich model [9] . It is a direct and concrete approach focusing on events, in contrast to Reich's synthetic methodology.…”

In this paper, for purposes of airspace planning, by the theory of statistical-probabilistic and theory of traffic engineering a mathematical expression of the parallel airways based on the variable nominal distance and airspace planning parameters is given. By using the estimation formula proposed the average number of collisions between the parallel airways can be calculated and the impacts of airspace planning parameters on the collision risk can be shown. A method to characterize the collision risk when the aircraft are flying on parallel airways and the collision risk when the nominal distances on parallel airways are variable is given in the progress of airspace planning which may provide some theoretical basis for airspace planners to determine the lateral separation minimum, and may give some references basis for researchers of air traffic flow to study the capacity of airspace and air traffic controllers to keep airspace safe.

“…On the basis of Reich's model and the improved models, the concept of Target Level of Safety (TLS) in airspace is proposed by International Civil Aviation Organization (ICAO) [10]. Besides, the studies on aircraft lateral separation minima in the North Atlantic region [11], aircraft vertical separation minima in Europe [12][13][14], aircraft longitudinal separation minima in the Asia-Pacific region [15], as well as collision risk analysis for Performance-based Navigation (PBN) procedures [16][17][18][19], are all based on Reich's study. The mentioned aircraft separation and collision risk studies contribute greatly to aircraft separation minima determination in the aspects of structured airspace and evolved flight procedure.…”

“…The risk values calculated using the developed models are only the relative measure of safety. This means that there are intended for the purpose of comparison between numerous scenarios, not for comparison with a Target Level of Safety (TLS) given by the international regulations [38][39][40].…”

Risk Assessment in Air Traffic Management

This chapter presents a conflict risk assessment based framework for airspace planning and design developed for the purpose of preventing aircraft conflicts and collisions. During airspace planning and design process, airspace designers are often guided by the need to increase capacity and/or reduce air traffic controller (ATCo) workload. In order to consider safety risks in a systematic way, the proposed framework contains an additional step-safety risk assessment, performed by safety analysts guided by the risk reduction need. In such a way, they are providing feedback to airspace designers regarding safety issues of their solutions. This chapter presents four conflict risk assessment models, each one developed for different airspace planning level (strategic, tactical, operational, and current day) contained in the proposed framework. Basic development principles for every model were explained together with specific objectives, assumptions, conflict risk concepts, and required input data. Models are illustrated by the simple numerical examples.
