A study compared three display pane's used by air traffic controllers. Each display panel was tested for four different simulated emergency conditions. Twenty-four highly trained air traffic controllers were used in the study. Two controllers were randomly assigned to each display panel-emergency condition combination. The time (in seconds) required to stabilize the emergency condition was recorded. The following table gives the resulting data and the JMP output of a two-way ANOVA of the data Emergency Condition m MAN 22 19 31 1 32 15 37 12 res Means Est in ate Condition Estime 24. 560860 32. 166667 3.303 nce Mean Square Prob 26. 1949 6-6961 Adjustment = Tukey Sto t Ratio Prob 2. 172604 -6.25 6. 6062- -16 - 3126 2- 172604 -12.79 1 - 172684 3.27 0. 6297- 2. 3521 . 5657 1. 172684 -6.54 0.6061- -11. 1479 2. 172604 9.52 . 172604 16.06 15 . 352reject Ition effect ise compariso of emergency conditions t. 2. connoen ervals.
