• Abstract:
  This study compared the effect of alternative graphic or ; numeric cockpit display formats on the tactical aspects of ; vertical navigation (VNAV). Display formats included: ; a) a moving map with altitude range arc, b) the same ; format, supplemented with a push-to-see profile view, ; including a vector flight path predictor, c) an equivalent ; numeric format, d) a numeric non-VNAV format. Sixteen ; pilots each flew four different approaches with each ; format in a Frasca 242 simulator. Vertical and horizontal ; flight technical errors (FTE), workload, and subjective ; display preferences were measured. VNAV displays ; improved vertical FTE by as much as a factor of two ; without increasing workload. Relative advantages of the ; graphics formats are discussed.
