A Methodology for Nowcasting Unstable Approaches

Abstract

The approach-and-landing is one of the most complex procedures in airline operations. 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.
