ABSTRACT "Pathway-in-the-sky" flight display formats appear to offer exceptional path-control precision forfuture transport operational environments requiring complex-path approaches. With theconversion from the present instrument landing system (ILS) to the microwave landing system(MLS) within the National Airspace System, complex-path approaches could be used forcommercial transport operations to address airport capacity issues. Therefore, the application of"pathway-in-the-sky" formats to commercial transport operations is being evaluated at variousflight display research laboratories. The introduction of true depth cues via stereopsis techniquesoffers a means of further enhancing these displays. The subject paper describes researchconducted to determine the effectiveness of two candidate pathway formats for landing approachand to investigate the effect of their presentation in stereo versus non-stereo displayenvironments. A real-time piloted simulation experiment comparing performance across thesefactors in a transport landing-approach task will be discussed.
