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.
