To mitigate the potential risks in this phase of flight, airlines and regulators have published stabilized approach criteria that require the flight crew to check a set of conditions at 1000’ and 500’ above ground level (AGL). If the stabilization criteria are not met, the flight crew is required to abort the approach by executing a go-around, which adds operational costs to the flight and reduces runway efficiency.267 pagesenCopyright 2016 Zhenming WangTransportationInformation technologyAviation safetyPredictionSupervised learningTrajectory analysisA Methodology for Nowcasting Unstable ApproachesDissertation
