A robust method for runway conflict resolution during take-off

Abstract

This paper deals with the design and analysis of a method for traffic conflict resolution during take-off. Technologies developed to date have addressed the issue of runway incursions through advisory alerting once a conflict is detected, leaving the critical go/stop decision with the crew. Based on an estimate of take-off performance, the proposed method has the capability of determining which of the two manoeuvres can be conducted safely with adequate levels of confidence. With this objective information, the crew can be directed into taking a safe conflict resolution manoeuvre. Runway incursion is a major hazard in commercial aviation, with an average of two incursions occurring every day in the United States alone [1]. Over the years, there have been numerous initiatives to mitigate the risk of runway conflicts, within both the US and Europe. Operators and airframers alike have initiated several awareness campaigns and runway safety programmes, promoting techniques for preventing runway incursions. These programmes have targeted wide ranges of aspects, with improvements proposed to operations, training and airfield design amongst others. These include enforcing strict ICAO phraseologies for radio communications, strict procedure for crew whilst manoeuvring on and crossing runways, changes to typical taxiing routes to avoid incursion hotspots and improved airfield signage and lighting techniques. Nevertheless, runway incursions still occur and indeed their mitigation remains on the NTSB’s most wanted list of safety improvements [2].
