7-3 PRIMARY FLIGHT CONTROLS
The KODIAK uses conventional ight controls for the ailerons, rudder and
elevator. The control surfaces are pilot actuated through input from either of
two conventional control yokes, located directly forward of each crew seat.
The control system uses a combination of push-rods, cables, sectors, and bell
cranks to control the surfaces.
Roll, pitch, and yaw trim are available through controls mounted on the
control pedestal, and on the left and right control yokes. Manual elevator
trim is available through a trim wheel located on the left side of the quadrant.
Electric elevator trim is operated by a switch located on the outboard side of
the left control yoke. Electric rudder and aileron trim are operated by switches
located on the control pedestal.
ELEVATOR SYSTEM
The two-piece elevator provides pitch control for the aircraft. The elevator
is of conventional aluminum construction with skins, a spar and ribs. Each
elevator is attached to the aft spar of the horizontal stabilizer at three hinge
points and to the aft fuselage with the elevator control sector.
Elevator motion is generated through the pilot’s control yokes by sliding the
yoke tubes forward or aft. A push-pull linkage is connected to a cable sector,
from which cables are routed through a series of pulleys to a sector located in
the tail cone The tail cone sector actuates a push/pull rod which is attached
to the elevator sector and elevator torque-tube.
AILERON SYSTEM
The ailerons provide roll control for the airplane. The ailerons are of
conventional aluminum construction consisting of skins, spars and ribs. Each
aileron is attached to the aft spar of the wing at two hinge points.
The left and right control columns contain control wheels, control tubes,
bearings and quadrants. An interconnect cable attaches the left control wheel
to the right control wheel. The aileron cable is divided into two loops: the low
tension loop and the high tension loop.
The low tension loop, located in the fuselage, is routed via a series of pulleys
from the left control wheel, under the oorboards and up the left sidewall to
a loop connecting bracket in the cabin overhead. The loop then runs from
the loop connecting bracket across the cabin to the second loop connecting
bracket, to the right sidewall, down the sidewall, under the oorboards, and
back to the left quadrant.
The high tension loop is located in the upper portion of the cabin and left and
right wings. It interconnects the loop connecting brackets in the cabin top
with the left and right aileron sectors installed in the wings. Aileron push rods
connect the wing aileron sectors to the ailerons and provide aileron actuation.
