PIPER CHEROKEE 180 āCā

LANDING GEAR
The three landing gears use a Cleveland 6.00 x 6 wheel, the main wheels being
provided with Cleveland single disc hydraulic brake assemblies, No. 30-55. All
wheels use 6.00 x 6 four ply tires with tubes.
The nose gear is steerable through a 30 degree arc by use of the rudder
pedals. A spring device is incorporated in the rudder pedal torque tube
assembly to aid in rudder centering and to provide rudder trim. The nose gear
steering mechanism also incorporates a hydraulic shimmy dampener.
The three struts are of the air-oil type, with the normal extension being 3.25
inches for the nose gear and 4.50 inches for the main gear.
The standard brake system for the Cherokee consists of a hand lever and
master cylinder which is located below and behind the left center of the
instrument sub-panel. The brake fluid reservoir is installed on the top left front
face of the firewall.
The parking brake is incorporated in the master cylinder and is actuated by
pulling back on the brake lever, depressing the knob attached to the handle
and releasing the brake lever. To release the parking brake, pull back on the
lever to disengage the catch mechanism and allow the handle to swing
forward.
Optional toe brakes are available to supplement the standard hand lever and
parking brake system.
CONTROL SYSTEMS
Dual controls are provided as standard equipment with a cable system used
between the controls and the surfaces. The horizontal tail is of the Flying Tail
type (stabilator), with an anti-servo tab which also acts as a longitudinal trim
tab, actuated by a control on the cabin ceiling. 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
