Regression Plots, Zone 1 Equivalent Thumbtip Reaches with the Left Hand to the Rudder Arm Switch, a Thumb Operated Control in the F-16A. The full-up seat position is represented by a solid line. Each successive line represents one inch down from the previous seat position. The full-down seat position is represented by the dotted line. To derive Zone 2 Equivalent Thumbtip Reaches, subtract 2.2 inches from Zone 1 values. Zone 1 Equivalent Thumbtip Reach (full-up seat) = Sitting Shoulder Height X 0.908 + 8.463, r = 0.68. N = >10.
