Touchdown Point

Global Positioning System technology has the potential to revolutionize both commercial and military aircraft landing procedures. It will enable pilots to fly complex, curved approaches rather than the more simple straight-in approaches necessitated by the Instrument Landing System used at most large airports. To complement this technology, Head-Up Display pathway symbology was developed for use in the aircraft to help pilots stay on course during these complex landings. Thirteen Air Force pilots used this pathway symbology in a simulator to land under Visual Meteorological, Partial Instrument Meteorological and Full Instrument Meteorological visibility conditions. Deviations from commanded flight path, as well as lateral and longitudinal deviations from a desired runway touchdown point, were measured. Results indicated that landing performance was acceptable for all pilots and functionally equivalent in all weather conditions. Results of this study suggest that pathway symbology could provide the cues necessary to successfully fly complex, curved approaches to landing. In addition, the merits of using Equivalency Analysis, rather than traditional Analysis of Variance in testing for performance differences is discussed.
