AIRPLANE & SYSTEMS DESCRIPTION
CESSNA
MODEL 172R (180 HP)
The empennage (tail assembly) consists of a conventional verti
cal stabilizer, rudder, horizontal stabilizer, and elevator. The vertical
stabilizer consists of a spar, formed sheet metal ribs and reinforce
ments, a wraparound skin panel, formed leading edge skin and a
dorsal. The rudder is constructed of a formed leading edge skin and
spar with attached hinge brackets and ribs, a center spar, a wrap
around skin, and a ground adjustable trim tab at the base of the
trailing edge. The top of the rudder incorporates a leading edge ex
tension which contains a balance weight.
The horizontal stabilizer is constructed of a forward and aft spar,
ribs and stiffeners, center, left, and right wrap around skin panels,
and formed leading edge skins. The horizontal stabilizer also
contains the elevator trim tab actuator.
Construction of the elevator consists of formed leading edge
skins, a forward spar, aft channel, ribs, torque tube and bellcrank,
left upper and lower
•v•
type corrugated skins, and right upper and
lower "V" type corrugated skins incorporating a trailing edge cutout
for the trim tab. The elevator tip leading edge extensions incorporate
balance weights. The elevator trim tab consists of a spar, rib, and
upper and lower
•v•
type corrugated skins.
FLIGHT CONTROLS
The airplane's flight control system (Refer to Figure 7-1) consists
of conventional aileron, rudder, and elevator control surfaces. The
control surfaces are manually operated through cables and
mechanical linkage using a control wheel for the ailerons and
elevator, and rudder/brake pedals for the rudder.
TRIM SYSTEM
A manually operated elevator trim system is provided (Refer to
Figure 7-1 ). Elevator trimming is accomplished through the elevator
trim tab by utilizing the vertically mounted trim control wheel in the
cockpit. Forward rotation of the trim wheel will trim nose down;
conversely, aft rotation will trim nose up.
