8.7 Airplane control systems
Airplane control systems include control systems for drooping ailerons (flaperons), elevator
with trim tab, rudder and nose wheel, engine and brakes.
The control system is combined consisting of foot- and hand-actuated subsystems.
Ailerons and elevator are hand-actuated and are controlled using yokes.
8.7.1 Elevator control system
The elevator control system linkage (see Fig. 4 ) is rigid, comprising 3 pushrods and 2
bellcranks. “Push” and “pull” forces are applied by the pilot to the yoke 1 is passed via the
control column 2 to the pushrod 3, then via the bellcrank 4 to the pushrod 5. The force is
transferred to the elevator via the pushrod 7, attached to the bellcrank 6. And the pushrod
7 is supported by the rollers 8 and connected to the elevator arm 9.
The elevator angles of deflection are: upward 25±1º, downward 15±1º.
