Aileron System

The ailerons provide airplane roll control. The ailerons are of
conventional design with skin, spar and ribs manufactured of
aluminum. Each aileron is attached to the wing shear web at two hinge
points.
Aileron control motion is generated through the pilot's control yokes by
rotating the yokes in pivoting bearing carriages. Push rods link the
pivoting carriages to a centrally located pulley sector. A single cable
system runs from the sector to beneath the cabin floor and aft of the
rear spar. From there, the cables are routed in each wing to a vertical
sector/crank arm that rotates the aileron through a right angle conical
drive arm.
