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.
