DESCRIPTION AND OPERATION
FLIGHT CONTROL CONSOLE

7.9 FLIGHT CONTROLS
Dual controls are provided as standard equipment, with a cable system used between the controls and
the surfaces. The horizontal tail (stabilator) is of the all-movable slab type with a trim tab mounted on the
trailing edge of the stabilator to reduce the control system forces. This tab is actuated by a control wheel
on the floor between the front seats (Figure 7-3).
The stabilator provides extra stability and controllability with less size, drag and weight than
conventional tail surfaces. The ailerons are provided with a differential action which tends to reduce adverse
yaw in turning maneuvers, and which also reduces the amount of coordination required in normal turns. A
rudder trim adjustment is mounted on the right side of the pedestal below the throttle quadrant and
permits directional trim as needed in flight (refer to Figure 7-5).
The flaps are manually operated, balanced for light operating forces and spring-loaded to return to the
up position. A past-center lock incorporated in the actuating linkage holds the flap when it is in the up
position so that it may be used as a step on the right side. The flap will not support a step load except when
in the full up position, so it must be completely retracted when used as a step. The flaps have three
extended positions, 10, 25 and 40 degrees.
