Flight Controls; Elevator - Cessna 152 Training Manual

Flight Controls

The aeroplane's flight control system consists of conventional aileron, rudder
and elevator control surfaces. The control surfaces are manually operated
through mechanical linkages to the control wheel for the ailerons and elevator,
and rudder/brake pedals for the rudder. A manually-operated elevator trim tab
is provided and installed on the right elevator.
The control surfaces are formed in a similar way to the wing and tail section
with the inclusion of the balance weights, actuation system (control cables etc)
and trim tabs. Control actuation is provided by a series of push-pull rods,
bellcranks, pulleys and cables with the required individual connections.

Elevator

The elevator is hinged to the rear part of the horizontal stabilizer on both sides.
The main features are:
an inset hinge with balance weights;
an adjustable trim tab on the right side.
The leading edge of both left and right elevator tips incorporate extensions
which contain the balance weights which aerodynamically and mechanically
assists with control input reducing the force required to move the control.
