Aileron Control System
The aileron control system, shown in figure 9-8,
is equipped with a power mechanism that provides
hydraulic power to operate the ailerons. If hydraulic
power fails, the mechanism can be disconnected,
placing the system in complete manual operation.
Movement of the aileron control system begins when
the control stick in the cockpit moves left or right.
When the stick is moved, cables connected to the bell
crank in the control stick housing are moved to
operate the sector on the power mechanism. With the
actuation of the sector, the power mechanism
operates, transferring the movement to the
mechanical linkage that operates the ailerons.
The aileron power mechanism consists of two
control valves, a dual-chambered hydraulic power
cylinder, cable sectors, and a system of latches and
related cranks. Linkage connects the control valves in
tandem. The flight control hydraulic system powers
