Back to REACH

Regression Plots, Zone 1 Equivalent Thumbtip Reaches with the Right Hand to the Horizontal Stabilizer De-Ice Backup Switch, a Thumb Operated Overhead Control in the Left Cockpit of the T-1A. Since this control is located overhead, subjects with higher shoulders can have shorter reaches to access it. This is illustrated by the reverse slope of the regression lines. Zone 1 Equivalent Thumbtip Reach (full-up seat) = Sitting Shoulder Height X -0.78 + 43.318, r = -0.94. N = <10.
