MODEL 152 7-8
FLIGHT CONTROLS
The airplane’s flight control system (see figure 7-1) consists of conventional aileron, rudder, and elevator
control surfaces. The control surfaces are manually operated through mechanical linkage using a
control wheel for the ailerons and elevator, and rudder/brake pedals for the rudder.
Extensions are available for the rudder/brake pedals. They consist of a rudder pedal face, two spacers
and two spring clips. To install an extension, place the clip on the bottom of the extension under the
bottom of the rudder pedal and snap the top clip over the top of the rudder pedal. Check that the
extension is firmly in place. To remove the extensions, reverse the above procedures.
TRIM SYSTEM
A manually-operated elevator trim tab is provided. Elevator trimming is accomplished through the
elevator trim tab by utilizing the vertically mounted trim control wheel. Forward rotation of the trim
wheel will trim nose-down; conversely, aft rotation will trim nose-up.
INSTRUMENT PANEL
The instrument panel (see figure 7-2) is designed to place the primary flight instruments directly in front
of the pilot. The gyro-operated flight instruments are arranged one above the other, slightly to the left
of the control column. To the left of these instruments are the airspeed indicator, turn coordinator, and
suction gage. The clock, altimeter, rate-of-climb indicator, and navigation instruments are above and/or
to the right of the control column. Avionics equipment is stacked approximately on the centerline of the
panel, with space for additional equipment on the lower right side of the instrument panel. The right
side of the panel also contains the tachometer, ammeter, over-voltage light, and additional instruments
such as a flight hour recorder. A subpanel, under the primary instrument panel, contains the fuel
quantity indicators, cigar lighter, and engine instruments positioned below the pilot’s control wheel.
The electrical switches, panel and radio light rheostat knob, ignition and master switches, primer, and
parking brake control are located around these instruments. The engine controls, wing flap switch, and
cabin air and heat control knobs are to the right of the pilot, along the upper edge of the subpanel.
Directly below these controls are the elevator trim control wheel, trim position indicator, microphone,
and circuit breakers. A map compartment is on the extreme right side of the subpanel.
For details concerning the instruments, switches, circuit breakers, and controls on this panel, refer in
this section to the description of the systems to which these items are related.
GROUND CONTROL
Effective ground control while taxiing is accomplished through nose wheel steering by using the rudder
pedals; left rudder pedal to steer left and right rudder pedal to steer right. When a rudder pedal is
depressed, a spring-loaded steering bungee (which is connected to the nose gear and to the rudder
bars) will turn the nose wheel through an arc of approximately 8.5° each side of center. By applying
either left or right brake, the degree of turn may be increased by up to 30° each side of center.
