Free-Flight in Europe, Problems and Solutions

Abstract

Earlier papers, based on a computer model of European air traffic, deal with the probability of conflicts arising between pairs of aircraft operating under free-flight rules. This paper discusses the problems of resolving these conflicts. When a potential collision takes place in the neighbourhood of other intruding aircraft, these must be taken into account when choosing an escape manoeuvre. A suggestion is made that may ease the problem. KEY WORDS1. Air Traffic Control.2. Safety. 3. Modelling.

An Integrated Air Traffic Control Display Concept for Conveying Temporal and Probabilistic Conflict Information

“…In particular, it remains to be shown that this concept will not hinder controllers' ability to manage air traffic at anticipated increased loads (Wickens, 1998). For example, an analysis of a one day sample of current Eurocontrol traffic, comprising 1000 intersections, showed that with free flight this number would likely increase to at least 62,000 intersections (Ratcliffe, 2001).…”
